Las Vegas Airspace Transition: GA Pilot’s Guide

For many GA pilots, the allure of trips with friends for fun and adventure is a big reason to fly. For flyboys in the southwest, sunny Las Vegas can be the next step beyond that classic $100 hamburger! Only a few hours from the bustling airspace of Southern California, the Las Vegas terminal area offers impressive views from the air, including the Hoover Dam, astounding Red Rock Canyon, and of course the iconic Strip. Read on to learn the nuances of a trouble free day navigating our busy Bravo airspace, and how to set yourself up for a successful red carpet ride down the Strip! With a little luck and some pre-planning, you can fly abeam Las Vegas Boulevard, with a view to rival those spendy Heli-tours. Just remember to observe your clearance minimums as the Stratosphere looms in your windscreen before the entrance to the KVGT pattern!

Arrival into Las Vegas

For our exercise, we will be approaching Las Vegas from the south with a destination of KVGT North Las Vegas. Be sure you take a moment to look at the Las Vegas TAC and FLY charts to familiarize yourself with the local landmarks. You’ll want to be aware of The Ridge, Bank of America Bldg, and the Stratosphere (referred to as Monument on the chart, but as its namesake on the radios). Also, take note that there are heavy skydiving operations just south of Jean airport, east of Interstate 15. They will announce on Jean’s CTAF (122.9) during active jumps.

Las Vegas TAC   Las Vegas FLY

Stratosphere

Set your course towards Jean airport (0L7) as you near Las Vegas. Your best bet is to have been using flight following on your trip in, but if not, contact Las Vegas Approach on 125.9 sometime before the mode-C veil. “Las Vegas approach, Piper 123XH, 30 miles South at 5,500, request bravo transition to North Las Vegas.” Depending on your altitude, this is also a good time to start listening for KVGT ATIS if you have a second radio, otherwise you end up with a high workload as you transition the bravo and get handed off to VGT tower. For the pilots who don’t often operate in Class B airspace, remember that ATC must explicitly clear you into the airspace; a vector and a transponder assignment wont be sufficient to keep you out of hot water if they didn’t say the magic words.

Once you have set your transponder and been cleared into the Bravo, expect to be vectored just west of KHND, and then directly over the numbers for RWY 25 at KLAS. This is where it gets fun! Shortly after you have flown abeam the end of RWY 19 and confirmed visual of the Stratosphere, expect to be granted own-nav, direct to KVGT, and instructed to remain above 3,500 until cleared below by North Las Vegas tower. This is a good time to slow the plane down, adjust your heading to get a bit closer to the scenery, and take in the view.

EncoreWynn

Soon after you fly abeam Wynn Resort (two striking bronze colored ellipse towers), you will be handed off to North Las Vegas tower. Mention the current ATIS identifier on initial contact, and expect to be given a turn instruction and your runway assignment. Depending on winds and traffic at VGT, you will be instructed to turn in before the Strat with a direct-in approach to RWY 30L/downwind for 12R, or turn after the Strat to fly a left base/cross into 25/7. Just remember that the tip of the Stratosphere is at 3,187’ (that’s above VGT TPA!), so maintain that lateral clearance; there’s a good chance that you will descend below it as you make your final turn into KVGT.

If approaching from the southeast, expect vectors to the Henderson (KHND) airport and from there a northerly heading as previously stated. There is skydiving activity at the Boulder City Airport (KBVU) so you will want to use caution when transitioning overhead. Also use caution for multiple helicopter tour operators operating between the ridge (south of KHND) and the Boulder City Airport (KBVU). They all will be on KBVU CTAF until the Boulder City substation (depicted on TAC southeast of KBVU) where they will switch to 120.650. It is recommended that you get flight following from Las Vegas approach when you approach from the southeast. Do note that if you are at an altitude of 8,500 ft or lower in the vicinity of KBVU, you may not be able to communicate with Las Vegas approach as there are many dead spots which are blocked by mountains and the Approach control transmitter site. You may also request the Cortez Arrival into KVGT with Las Vegas approach which starts at Lava Butte(depicted on TAC chart south east of Nellis(KLSV)). You will need a Bravo clearance to fly this arrival. The instructions for this arrival can be found on the inset of the TAC chart. Expect numerous helicopter arrivals to operate underneath you at 3000 to KLAS and KVGT. Their route will take them from Lava Butte to the Stratosphere tower, almost directly under the same path you will take. Also note multiple arrivals to 19L/R to KLAS if the winds are from the south or southeast. Expect to maintain 3,500 until entering the KVGT class D airspace.

If You Don’t Get Cleared into Bravo

If for some reason KLAS isn’t able to accommodate your flight through their airspace, there is a VFR Flyway, which is illustrated on the TAC chart. Follow the 15 Freeway while descending below 4,000, and turn west before you enter KHND airspace. The SFC Bravo is 6 NM from the LAS VORTAC, so use your DME to remain clear of the airspace, following this route to the north. Contact KVGT tower before you reach the Bank of America building.

Touchdown

Once you’re on the ground, you will find transient parking just north of taxiway B at H, with self-serve fuel a bit further north nearby. Do look ahead at the hotspots indicated on the VGT diagram, as this airport is well known for runway incursions. You’ll typically find Ground Control to be accommodating, and it is recommend to request a taxicab over UNICOM (122.95) if you’re planning to use one; the wait can be at least 30 minutes. The fare will average $30-$35 plus tip to get to the Strip. KVGT does have a restaurant on the airport. There are also a number of restaurants at the nearby Hotel/Casino. A second option is to head back to Henderson Executive where there is a great diner with fantastic second floor views of the runway, and a full bar for your passengers!

Heading South

So you’ve won the jackpots, seen the sights, and eaten at the buffet, but now it’s time to think about your trip back out of the valley. Luckily, the transition south is almost identical to the flight in, so go ahead and request the Bravo transition south when you contact KVGT Ground for taxi instructions. KVGT may or MAY NOT coordinate for you, but if not they will give a departure heading, and frequency to contact LAS TRACON to make your request once in the air. Dial this into your second radio if you have one, because you’ll need it soon after rotation.

If you are interested in seeing the Hoover Dam and the tallest concrete span arch bridge in the world request an east departure with KVGT tower. You will also want to make this request if you are headed back to the state of Arizona or towards the Blythe (BLH) VOR. You’ll be handed off to Nellis approach upon departure. You can expect to maintain 5000 and expect vectors to pass right over the center of Nellis AFB (KLSV). Inform them that you will cancel over the Gypsum Mine which is just east of KLSV and depicted on the TAC (on the sectional it is depicted as plant and strip mine). Pilots are requested to monitor 120.65 and it is highly suggested. Be alert for high volume tour traffic in the area. Also observe FAA advisory circular (AC) 91-36, which requests 2,000 AGL clearance in noise sensitive areas. Most of the tour companies over the Hoover Dam will approach the dam from the northwest or will approach from the Boulder City substation which is depicted on the TAC chart just southeast of Boulder City Airport (KBVU). They will be helicopters and will be operating at 3500 on the tour. Be alert for fixed wing tour traffic as well departing from KBVU heading east as well as those returning from the Grand Canyon landing at both Boulder City and Henderson Airports. If you want to skip the dam, inform Nellis approach that you’d like flight following. Expect the vectors out of KVGT as stated above. As you get towards the Gypsum Mine, expect to be handed off to Las Vegas Approach and expect Higher with them.
If the dam doesn’t interest you, you’ve requested a departure to the south-southwest from KVGT tower. Expect a heading assignment on departure with a frequency to contact Las Vegas Approach. You can expect vectors to the west of McCarren airport. You will most likely receive a Bravo clearance unless McCarren is landing runway 7R (usually in the summer months). Out to the west you can expect stunning views of Red Rock National Conservation area off the right side of your airplane. Use caution however getting too close to the mountains out west when the wind is high as downdrafts and turbulence will be present.
Flying around Las Vegas Airspace

Arrows indicate Lava Butte and Hoover Dam

If you’d rather get right out of town without traffic advisories, depart heading 220, remaining north of the Bank of America Building. Once you’ve passed Bank of America, skirt the SFC section of LAS Bravo, remaining 6 NM from the LAS VORTAC and below 4,000’. Follow this around until you have visual of the 15 Freeway, and turn south once you are abeam KHND. There will be varied terrain to the Starboard side of the aircraft, so beware of CFIT and keep a close eye on your altitudes as you climb out; You’ll be flying beneath a major approach corridor for McCarran. It is also recommended to be on frequency with Vegas approach, which KVGT should provide as you exit their airspace(expect 125.9). Be sure not to cross into KHND airspace as you round the bend unless you have radio contact with Tower.

Master Takeoffs & Landings – Land Like a Professional

So you’re a pilot. You can successfully takeoff & land an airplane. BUT – just how good are you? How precise are you? Can you land your airplane like a bush pilot, on an actual soft field AND over an obstacle? Can you land within 25 feet of where you intended to touch down? Can you handle cross-winds with ease & max out the performance of your airplane on takeoff? Do you know the proper techniques for landing on a wet runway?

Learning to land like a pro means precision, safety, and consistency. Whatever skill level you’re at now, mastering takeoffs and landings to a higher proficiency & skill level will make you a safer pilot, and you’ll have more fun! Most accidents happen on takeoff & landing, after all.

After completing this course, you will be more proficient, more precise, and have more fun doing takeoffs & landings than you every had as a pilot. For finishing you’ll get your name on the DFC website T/O & Landings course page (this page), plus a certificate of completion. Rest assured, this is an excellent way to level up your piloting skill. Plus, who doesn’t just want a reason to go fly?! See the detailed syllabus below, and contact DFC to get started on your path to mastery with one of our skilled instructors!

Small Plane Crash near Las Vegas, April 2016

It’s a sad & sobering thought in any pilot’s life when we hear of something that hits close to home: a plane crash. According to news sources, this recent Saturday, April 30th, an Extra 300 that departed from Henderson Executive Airport crashed near the Nevada California border, killing both occupants on board. Not much is knows about the accident other than that. There seem to have been a rash of airplane accidents recently in the Las Vegas valley area. Each time it happens, we’re reminded as pilots of the risks we take every time we climb into the cockpit of an airplane. Our loved ones feel the stress when we hear about accidents like this. We’re reminded that the thing we love so much – flying – is rife with risks.

These kinds of incidents are a good reminder to us that proper & frequent training, and a healthy attitude toward safety & the risks we take, are a key to minimizing that risk. We should take each one of these as an opportunity to reflect on ourselves as aviators, and confront the deficiencies we know we have. Every pilot could be safer. Each flight could have been a little better planned out. We could have been slightly more prepared and familiar.

What happened recently is a tragedy, and our hearts & prayers go out to the families of the crash victims. I urge all of our members and pilots in our communities to always play it safe when it comes to aeronautical decision-making. General Aviation still has an excellent accident record & it is still a very safe industry, but there’s always something more we could be doing to ensure airplane accidents don’t happen or if they do – they have a successful outcome.

Here are some links to the developing story. Again, our best goes out to those involved.

The 9 Deadly Sins of Aircraft Performance

Many of our members attended a FAAST seminar about aircraft performance recently. It’s a very important subject, especially to those of us flying in mountainous terrain, in single-engine normally aspirated airplanes! Mr. Stephen Ruks did an excellent job, and agreed to share the powerpoint slides & notes with us to post here. Enjoy reading – and be safe!

The Nine Deadly Sins POWERPOINT:

 

Slide 2 – References

Pilots Handbook of Aeronautical Knowledge Ch. 7 & 10

Your AFM or POH

AC 00-6A Aviation Wx

AC 61-84B Role of Preflight Preparation

FAA-P-8740-2 Density Altitude Brochure

 

Slide 3 – Wings Program – What is one of the best things you can do to stay safe?

Chances are 97% greater that you won’t have an accident if enrolled in Wings

Slide 4 – Introduction – Misunderstandings or lack of knowledge about our atmosphere and how it affects aircraft performance is one of the leading causes of fatal aviation accidents.  This seminar will remind you of some of the things you already know and maybe show you a few things you didn’t know.

Slide 5 – Altitude types – How many altitude definitions are there?

  1. Indicated altitude
  2. True altitude
  3. Absolute altitude
  4. Pressure altitude
  5. Density altitude

Read on your altimeter

Height above MSL

Height above ground level

Indicated altitude set at 29.92

PA corrected for non-standard temperature

  1. Indicated altitude—read directly from the altimeter (uncorrected) when it is set to the current altimeter setting.
  2. True altitude—the vertical distance of the aircraft above sea level—the actual altitude. It is often expressed as feet above mean sea level (MSL). Airport, terrain, 7-7 and obstacle elevations on aeronautical charts are true altitudes.
  3. Absolute altitude—the vertical distance of an aircraft above the terrain, or above ground level (AGL).
  4. Pressure altitude—the altitude indicated when the altimeter setting window (barometric scale) is adjusted to 29.92 “Hg. This is the altitude above the standard datum plane, which is a theoretical plane where air pressure (corrected to 15 °C) equals 29.92” Hg. Pressure altitude is used to compute density altitude, true altitude, true airspeed (TAS), and other performance data.
  5. Density altitude—pressure altitude corrected for variations from standard temperature. When conditions are standard, pressure altitude and density altitude are the same. If the temperature is above standard, the density altitude is higher than pressure altitude. If the temperature is below standard, the density altitude is lower than pressure altitude. This is an important altitude because it is directly related to the aircraft’s performance.

 

Slide 6 – Pressure – How do we describe atmospheric pressure, what is it, and how does it affect us?   ^  More importantly, how does it affect our airplanes?

Slide 7 – Pressure – What causes pressure variations?

^          Altitude – Pressure decreases approximately one inch of mercury per 1000 feet increase in altitude.

^          Temperature – The rate of decrease of pressure with altitude in warmer air is less than in colder air.  You will have to climb higher in warm air to reach the same pressure altitude as in cold air.  Temperature id the biggest factor affecting density altitude

Slide 8 – Pressure Gradient – Given the same change in pressure, the rate of change of pressure is greater in cold air than in warm air.

Slide 9 – Effect of non-standard temperature – Notice that True Altitude varies with variations in temperature along the same pressure line or gradient.

Slide 10 – Typical GA Pitot System – Explain disadvantage of having static port on only one side of aircraft. Briefly discuss effects of icing on pitot-static system.  If both ram and drain holes freeze up with ice, airspeed indicator acts as an altimeter – the higher you go the higher the airspeed reads.  If static port freezes up, altimeter and VSI remain constant and airspeed is not accurate.

Slide 11 – Altimeter – Give brief description of how an altimeter works.

Slide 12 – Altimeter Setting – Standard Atmosphere:

29.92 inHg    or

1013.25 hPa (or mb)

at sea level @ 59º F (or 15º C)

One inch of mercury = 1000 feet

One hectoPascal = 100 millibars

1 inHg = 33.8653 hPa  —  Use this for conversion between inHg and hPa

Slide 13 – High Density Altitude

Three important factors contribute to high density altitude:

  1. Altitude
  2. Temperature
  3. Humidity

Reduced air density equates to decreased performance

Explain chart below:

Slide 14 – High Density Altitude

Warmer air will hold more water vapor than cooler air which affects engine performance more than aerodynamic performance.

With high humidity, expect longer take-off rolls and lower climb rates.  Add 10% to take-off distance.

Slide 15 – The Nine Deadly Sins (and their unforgiveness)

Kurt Anderson, an NTSB Investigator, who has investigated more than 400 accidents, gave a seminar on the results of interviews with many of the pilots who survived accidents and discovered nine things that pilots learned and then forgot, never learned at all, or learned wrong.  Those nine things have been dubbed “The Nine Deadly Sins.”  Scott Gardiner of Seattle FSDO published, in FAA Aviation News, May-June 2004, the article discussing those nine deadly sins.  Now I’m going to present them to you.

  1.   Using sea level VSPEEDS
  2.   Using gross weight VSPEEDS
  3.   Ignoring effect on TAS
  4.   Ignoring effects in mountainous terrain
  5.   Ignoring effects on landing speed and distance
  6.   Ignoring climb gradient
  7.   Ignoring runway environment
  8.   Using incorrect flap settings
  9.   Combining soft-field and obstacle techniques

“Practical Density Altitude” by Scott Gardiner, FAA Aviation News, May-June 2004
Slide 16 – Sin #1 – Using Sea Level VSPEEDS

Slide 17 – Sin #1 – Using Sea Level VSPEEDS

If you mistakenly attempt to climb at your sea level indicated best angle of climb speed, you are probably four to seven knots too slow. You have taken an airplane whose climb performance may be poor at best and made it downright lousy!  There is a really good chance the airplane will not climb at all and will simply mush into the obstacle as you will see later on in this presentation.  You will also see later that combining techniques can prove to be hazardous.  Use best rate of climb for the density altitude you are flying and never best angle of climb except for nearby obstacles.

There are some serious drawbacks to using best angle.  A full power climb results in a high pitch angle (so much for see and avoid), poor engine cooling, close to stall speed, and may be uncomfortable for passengers.  Avoid best angle of climb.
Slide 18 – Sin #2 – Using Gross Weight VSPEEDS

Vy decreases with decrease in gross weight

If you attempt to climb out of a high density altitude airport at a reduced gross weight while using your sea-level, maximum gross weight best rate of climb speed (indicated), you combine Sin#1 with Sin #2.  The result can easily be that you are attempting to climb at a speed that could be 15 knots too fast!  Such a mistake can turn minimal climb performance into negative climb performance!  This deadly combination is precisely what is leading to our most common density altitude accidents!

Explain the effect of DA on TAS using above chart.  See next page . . . .

Slide 19 – Sin #3 – Ignoring effect on TAS

Turn radius increases by the square of the TAS.  The formula is TAS2/11.26 tan Θ.  Assuming IAS of 150 @ sea level, standard temperature, the turn radius would be ≈ 2000’, or one-third of a mile,  But at 8000’ with a temp of 95º your TAS is now 180 and the turn radius increases to ≈ 3000’.  But remember!  That’s turn radius – you have to double that for a 180º turn!  You now need a full mile to turn around and that’s using a 45 bank angle for the maneuver.  How much more power do you think you’ll need at 60 degrees of bank – remember the drag goes up 300%!

So you tell yourself, “Just slow down, turn radius will decrease.”  But now with this increased AOA how much more drag are you adding.  Remember, the slower you fly, the higher the induced drag, and it’s multiplied by 300%.  Does your engine have enough power reserve?  Very doubtful, that’s why we have the accidents.

IAS = 150

PA = 8000

Temp = 95ºF

TAS = 180

DA = 12,000

Looking at this Lift-Drag Chart, I want to throw an additional factor into it.  Consider an airplane in a 30 degree bank.  Induced drag increases by 33%.  At 45 degrees, it increases by 100%, and at 60 degrees it increases by 300%.  This is not shown on a normal L-D chart but imagine how much power your engine must now develop to maintain altitude in a 60 degree bank at a high DA (12,000’) where your engine is struggling to maintain power and altitude.

Slide 20-21 – Sin #4 – Ignoring the effects in mountainous terrain.

Considering all the information I’ve just presented to you, let’s look at the three airplanes flying straight out of the screen.  Consider the effects of wind as depicted by the arrows   Strong downdrafts for airplane #1 requiring additional power to maintain altitude.  Airplane 2 is scooting along normally, and airplane 3 is enjoying the advantage of the updraft.

“Flying in the vicinity of a ridge results in downdrafts for the pilot of Airplane 1. Airplane 2 might escape the downdrafts, but a course reversal either to the right or to the left would leave little maneuvering room between the airplane and the ridge.  Airplane 3 takes advantage of free lift from the up slope airflow and retains the advantage of an into-the-wind escape route.”  The official explanation is technically correct, but it does not go far enough. Since it is questionable whether or not Airplane 2 can complete a 180-degree turn, we can assume this valley is not very wide. Most pilots choose to fly up the correct side of the valley (Airplane 3 in this case), but push on too far before deciding to reverse direction. As long as things are going well for Airplane 3, the pilot continues bravely on course. It’s only when things get tight that the pilot of Airplane 3 decides to make the 180 but turning around at this point results in a radius of turn that places the airplane somewhere between Airplanes 1 and 2. This is precisely the valley location described in the official explanation as an area of downdrafts! The trap has been sprung. Another aircraft smacks the terrain and often with fatal results.

Slide 22 – Sin #5 – Ignoring Effects on Landing Speed and Distance

Often times the discussion of density altitude is limited to takeoff distance and maybe even climb performance.  But you have to think of what the airplane is doing when approaching to land as well.  Remember the TAS is higher than IAS at density altitudes above sea level so that has to be considered.  Imagine a worse case scenario of a  runway at 8000’ elevation that downslopes to the edge of a cliff and is only 2500’ long and you  have a 10 knot tailwind.    So down you go to the landing.  You get about halfway down the runway where you finally touch down and you realize that you may not be able to stop so smart pilot that you are you add power for a go-around forgetting that you placed the mixture in full rich for the landing.  Are you going to have enough power for the go-around and be able to clear all obstacles in the process?  Do you see how these hazards add up and why it is so important to plan ahead?  Consider all the variables before operating in high density airports.

Slide 23 – Sin #6 – Ignoring Climb Gradient

When departing airports, be aware of your climb gradient. We are all familiar with aircraft rate of climb — it’s figured in terms of feet per minute.  Climb gradient is figured in terms of feet per mile.  Consider two airplanes, each climbing at 500 feet per minute. But one is climbing at 60 knots, and the other is climbing at 90 knots. Each will climb 500 feet in one minute. But the first will cover one mile during that minute, and the second will cover a mile and a half during the same minute. The first airplane is climbing 500 feet per mile, and the second is climbing only 333 feet per mile.

Remember that climb gradients are calculated in feet/nm not feet/min.  And be sure to use TAS (or GS) for calculations not IAS.

Consider the ILS approach to Ketchikan, Alaska.  Minimums are 288’ but the required climb gradient for the missed approach requires 335’/NM to miss a 4000’ mountain directly in front of you!  Localizer circling minimums are 2440’.

Slide 24 – Sin #7 – Ignoring Runway Environment

Watch the video clip of the A36 takeoff and think about what might have gone wrong.

OAT = 97F, Field Elev =1293’ Altimeter 29.89”

Density Altitude = 4125’, Rwy 31 4000’ paved

1996 A36, Turbonormalized IO-550,

GTOW = 4095,  CG = 86.15”

Different piloting techniques may have resulted in a much nicer outcome.

Now think of departing at our 8000’ elevation runway with the temperature at 95 degrees (DA 12,000’).  How well is that going to go?

Slide 25 – Sin #8 – Using Incorrect Flap Settings

In the A36 incident, use of flaps may have made the situation even worse!

Use of the recommended flap setting works just fine when operating at near sea level altitudes but with non-turbocharged engines, there is a density altitude above which the use of takeoff flaps actually increases ground roll.  Be sure to check the POH to ascertain if the use if flaps is recommended at high DA.

Page 26 of the A36’s POH Supplement stated, “However, when operating at the increased weights authorized when operations are conducted in the NORMAL CATEGORY expect the following:

  1. Increased Takeoff Distance of up to 30%.
  2. Decreased Rate-of-Climb of up to 13%.
  3. Increased Stall Speed of up to 7%.
  4. Increased Landing Distance of up to 15%.
  5. Increase Takeoff and Approach Speeds 2 kts.
  6. Increase VX and VY Speeds 2 kts.”

Soft field techniques should be saved for soft fields.  Just because the runway is of dirt or grass, it is not necessarily soft!  Mud in which you leave 3” tracks, beach sand, 6” of snow, or 3” of sleet is a soft field.

Slide 26 – Sin #9 – Combining Soft-Field & Obstacle Techniques

Normally flaps are only used on soft field takeoffs but when used for obstacle clearance, the increase in drag drastically hinders climb performance.

There are numerous instructors out there who routinely combine obstacle takeoff techniques with soft-field takeoff techniques to save time during training. But in actual density altitude situations, a pilot should not combine the two in a normally aspirated, piston-engine airplane.

If we are trying to clear a 100’ tree, we are talking about obstacle clearance takeoffs

not minimum ground-run takeoffs.

For obstacle clearance takeoffs, follow the advice of your airplane manufacturer, which for the vast majority of non-turbocharged airplanes means flaps up and climb at best angle of climb speed for the density altitude.

Always follow manufacturer’s recommendation.

Slide 27 – Summary

Beware, better yet, be knowledgeable, of the Nine Deadly Sins of Density Altitude

Remember the effect of DA on TAS and the TAS effect on airplane performance and humidity on engine performance.

Engine performance degrades with altitude

Desert Flying Club is forming as a non-profit organization, and we need your help!

We have formally incorporated as a non-profit in Nevada, and our current acting Board of Directors have been meeting, discussing the formation and future of the club! It’s very exciting, and there is lots of work to do.

That’s why we need your help! There will be a lot of volunteer time & effort that goes into forming this organization and making it truly a great place to rent inexpensive airplanes, meet life-long friends, and become a more competent, safer pilot. So we’re searching for motivated people who can fill the following roles:

  • Board of Directors
  • Safety Officer (holds safety meetings & promotes best-practices that will increase our safety in flying)
  • Event Committee Member (organizing fly-outs, social events, member communication of events, etc)
  • Flight Instructors (must be DFC-approved, and have a current CFI rating)
  • Aircraft Lessors (own or want to buy an airplane & offset your cost of ownership by leasing back to DFC)
  • Members! (we are accepting membership applications! Contact us for more info!)
  • Any & Every volunteer – you tell us what you’d like to do or if you’re just interested in getting involved!

We have seen an immense amount of interest in the club so far. Get involved in the local aviation community & be part of something growing! You can email info@desertflying.club or use the contact us page to let us know if you or someone you know is interested in helping.
