Scud Running

I was speaking with a pilot a few months back who was not instrument rated.  He was telling me of his flying experience while continually speaking fondly of scud running.  He told me several stories, most of the time with a smile on his face, about scud running to his destination while staying clear of clouds.  While he was talking, my mind was cycling through the numerous accident reports I’ve seen where a scud running VFR pilot has crashed into terrain or an obstacle.  Needless to say, scud running is not a very good idea.

This pilot’s stories got me to thinking, how common is the practice of scud running amongst VFR only pilots?  As an instructor, I always teach my private students about personal minimums and making that no-go decision when clouds are below those personal minimums.  The act of scud running falls under several of those dangerous pilot mindsets, get-there-itis, invincibility, and macho-ism, to name a few.

To bring everyone on the same page, let’s define scud running.  Wikipedia has a very good definition:

Scud running is a practice in which pilots lower their altitude to avoid clouds or instrument meteorological conditions (IMC). The goal of scud running is to stay clear of weather to continue flying with visual, rather than instrument, references. This practice is widely accepted to be dangerous, and has led to death in many cases from pilots flying into radio towers and high tension wires; however, even instrument-rated pilots sometimes elect to take the risk to avoid icing or embedded thunderstorms in cloud, or in situations where the minimum instrument altitudes are too high for their aircraft.

To put some numbers with that definition, a scud running VFR pilot would takeoff with a 1200-1500 foot ceiling and stay 700-1000 feet above the ground, right in the area where towers, hills, and rapidly rising terrain reside.

Scud Running

How do we change this mindset?  Well, if someone has been scud running for years without incident, the practice becomes normal, like the pilot I mentioned above.  The mindset of invincibility sets in and the practice continues.  This particular pilot can also lead other pilots to adopt the same practice, encouraging them that nothing will happen to them, since we all know that our pilot peers know better than our flight instructors (insert heavy sarcasm here).

In order to change this mindset, instructors need to emphasize personal minimums from day one.  This includes ceilings, visibility, and winds.  For a seasoned pilot, a review of accident statistics might help the process.

Scud running is not a safe practice.  If you’re a scud runner, you need to rethink your attitude.  Is getting there really worth it?

Still not convinced?  Read this pilot’s experience from AOPA.

  • A Takeoff Briefing

    Takeoff briefings are one of those things that most pilots are taught when they first learn how to fly, but once they get into flying themselves around, quickly fall by the wayside.  There is a reason student pilots are instructed to perform a takeoff briefing before departure.  It gets them thinking about what the plan is after they get off the ground and what to do if something goes wrong.

    Takeoff Briefing

    Takeoff briefings are a good habit to get into.  Airline crews do a takeoff briefing before every departure, even though they have performed a takeoff in that particular airplane thousands of times.  It enhances safety and provides repetition, keeping that knowledge at the forefront of the crew’s minds.

    In general aviation, a takeoff briefing should cover what the takeoff procedure is, what the abort plan is, and what the plan after takeoff is.

    Takeoff Procedure

    Most pilots fly the same airplane all the time, so the familiarity with what goes into a takeoff is there.  But, habits should be formed to brief the takeoff procedure as part of the takeoff briefing.  It doesn’t need to be extensive, just covering the basics of how the airplane is getting off the ground.  Something like this:

    • Throttle setting (if turbo charged, will full throttle cause an overboost?)
    • Rotate speed
    • Expected takeoff roll

    That’s it.  Nothing fancy for the takeoff procedure.

    Abort Plan

    What is the plan if something goes wrong?  It doesn’t have to be an engine failure, maybe the engine coughs when full power is added or maybe the engine doesn’t produce peak RPM.  Maybe the takeoff roll is longer than anticipated and something doesn’t seem right.  Maybe on climb out a door pops open.  Maybe the engine fails at 1,000 feet.  It’s good to keep the plan in the foreground for what to do if an abnormal or emergency situation takes place.

    • Brief the aborted takeoff procedure
      • Pick an abort point on the runway based on the expected ground roll
      • What is the procedure if the airplane isn’t off the ground by then?
      • What is the procedure if the engine quits on the runway?
    • Brief the engine failure procedure at low altitude
      • If the engine fails over the runway, will you try to land on the runway?
      • What altitude would you elect to turn back as opposed to landing straight ahead?
      • If the plane is too low to turn back, would you land straight ahead or aim left or right?
      • What airspeed will you aim to hold if the engine fails?
    • In a Cirrus, what is your minimum parachute deployment altitude?

    After Takeoff Plan

    After the airplane is off the ground, what’s the plan then?  Are you staying in the pattern or departing the area?  Do you need to adjust your power at a certain altitude?  What altitude are you climbing to?  What heading are you going to fly?  Is your flight plan in your GPS?  This is an excellent time to set up altitude and heading bugs if your airplane is so equipped.

    Get in the habit of doing a takeoff briefing before you call the tower or announce your departure.  It get’s your mind focused on the task at hand and then what is going to be happening next.

  • The Aunt Betty Directive: PFD Failures

    Glass panel displays, ballistic parachute aircraft recovery systems, portable tablet computers enabling paperless cockpits, and widely available three axis autopilot systems have changed the way we fly, the way we train, and the way we are expected to perform on check rides. Our training and testing paradigms have tried to stay in synch, yet always seem to be catching up to the latest levels of technology.

    This is very apparent when we instructors are preparing a student for an FAA practical test. When training aircraft had no autopilots, no GPS, and certainly no parachutes, the general philosophy was that during training, the student should have the lowest level of technology available. This was also the expectation on the check ride. This theory has changed over the years and now the Practical Test Standards require that an applicant integrate all available technology while demonstrating mastery of his or her aircraft. This raises numerous questions from instructors and students about what technology will be available for each task.

    One example of this dilemma is found when contemplating an instrument airplane practical test in a Cirrus SR20/SR22. The test requires the task “Instrument Approach without Primary Flight Display”, which has taken the place of what was the partial panel approach, accomplished without use of gyroscopic heading and attitude indicators. In the Cirrus, the standby attitude indicator, standby airspeed, and standby altimeter are available, as is the Multi-Function Display. Guidance from the FAA has us shooting a GPS approach using the moving map display on the MFD after disabling the PFD. Those of us who trained and tested in steam gauge aircraft think that this task should be fairly easy. With a fully functional Attitude Indicator and a nice big moving map display showing our course, a reasonably competent instrument pilot should have little trouble adapting to this setup and flying a good approach.

    But, in the Cirrus specifically, and perhaps in other aircraft as well, another question comes up. Can the applicant use the autopilot (which still works just fine after a display failure) during the approach without the PFD? A rather famous DPE who writes for a national magazine says “yes”, opining that not to allow its use would be introducing simultaneous multiple systems failures, which is strictly forbidden in the minds of some. If we follow this logic, we would not test simulated engine failure emergencies in these aircraft either, because to do so would imply failure of not only the engine, but the CAPS parachute system as well. In my former role as a pilot examiner, I always said no, that the approach should be hand flown. Here is my logic.

    I was amazed that flight instructors and examiners would accept the substitution of autopilot technology for the skill required to fly an approach without the PFD. I would argue that the intent and the well described emphasis of the PTS is that the applicant must demonstrate the ability to control the airplane after a loss of the primary flight display, not observe and monitor the autopilot controlling the airplane! This argument was generally unpersuasive, so I approached from a different point of view, that of a concerned family member.

    “Aunt Betty” represents a future passenger flying with the soon to be rated instrument pilot. Here is the question posed to Aunt Betty: “When we train and test pilots for instrument proficiency, we require them to demonstrate the ability to safely and skillfully fly the airplane without their primary instruments. Now, Betty, in this airplane, we can test this task in one of two ways. We would like your input on which way you would prefer, seeing as you will be a frequent passenger with your nephew. We can either have the pilot (might be your son, brother, husband, or nephew) demonstrate that he can fly the airplane by hand without the PFD, which does require a little more skill and a slightly different technique, or, we can require the pilot to perform this task using the autopilot so that the pilot basically monitors the airplane flying itself on the approach.

    “Now, Aunt Betty, a pilot allowed to use the autopilot system on this approach may not have the skill or technique to fly the approach by hand in the clouds should the autopilot shut down due to turbulence or mechanical failure. Should this happen to a pilot without the skill and practice normally required, the odds of a fatal accident occurring would be quite high.

    “So what do you think, Aunt Betty? Would you feel more comfortable flying with this fellow if he has demonstrated mastery of the aircraft (sans PFD) without the autopilot or only with its assistance?”

    This leads us to a larger discussion about the use of other technology, iPad, GPS moving map, and more. If technology is used as a replacement for pilot proficiency during training and testing, we end up with less skillful, less competent and ultimately less safe pilots. But, if we require that our students demonstrate mastery with the lowest available level of automation and technology (which, by the way, implies excellent fundamental aircraft control skills) then, when technology is added into the equation, we have a safer pilot.

    Technology can be a value added safety multiplier, or it can be a crutch needed to make up for lack of fundamental and advanced skills. Crutch or Safety Multiplier, which one will you choose? I know which one Aunt Betty prefers.

  • The Importance of Density Altitude

    Density Altitude:  Pressure Altitude corrected for non-standard temperature.

    That’s the book definition of density altitude.  The problem is, that definition leaves a lot of general aviation pilots scratching their heads.  What really is density altitude?

    All airplane engines rely on air and fuel mixing together, then that mixture is ignited to create combustion. Normally aspirated piston engine airplanes get their best performance at sea level, where the air is nice and thick, allowing plenty of air molecules to get sucked in the engine intake.  As a normally-aspirated airplane climbs, the ambient air pressure drops with an increase in altitude (the air gets thinner, less dense), thereby reducing airplane takeoff, climb, and landing performance.  There just isn’t as much air at higher altitudes, to put it simply.

    Turbo charged piston engines assist with this air density problem.  A turbo charger boosts the air coming into the engine and fools the engine into thinking it is at sea level pressure all the time.  The higher the altitude, the faster the turbo charger spins, spinning the compressor faster, which compresses more air to continue to give the engine sea level pressure air.  This gets faster cruise speeds the higher you go.

    Both normally aspirated & turbo charged engines do experience longer takeoff rolls and reduced climb rates at higher airport elevations & higher altitudes.

    How does this all relate to density altitude?

    When the outside air temperature rises, the air becomes thinner, less dense.  This means that when an airport elevation is 1,000 feet, but the density altitude is reported as 3,000 feet, the airplane engine thinks it is at 3,000 feet.  It won’t accelerate as fast.  The airplane’s climb rate will also be reduced.  That means that the normal climb pitch attitude a pilot is used to seeing won’t be accurate at higher density altitudes. It will lead to slower indicated airspeeds, slow enough to potentially lead to a stall if a pilot isn’t paying attention.

    Where does this get dangerous?  High elevation airports.  Whenever the OAT creeps above 85 or 90 at an airport that is higher elevation (I would classify higher elevation as 2,500 feet or higher), the corresponding density altitude sky rockets.  If a pilot isn’t paying attention to airspeed or angle of attack (if the airplane is equipped with an AOA), a stall can come very quickly on climb out.

    What to take home from this?  Monitor your climb speed and angle of attack, especially right after takeoff, when you hear density altitude on the ATIS or AWOS.

    Airplane Covers

    If you’re going to be leaving your airplane outside at your destination, make sure you have proper covers and plugs to protect it while you are gone. A friend of mine forgot to put his pitot cover on his airplane while it was parked outside and had his departure delayed because of a mud dauber which had moved in while the airplane sat on the ramp.

    Tie-Down Ropes

    Depending on your destination airport/FBO, there may or may not be tie down ropes available on the ramp. It isn’t uncommon for there to be tie down loops, but no ropes. I generally try to carry a set of ropes in the airplane and even my own set of chocks. If you are going to a fly-in or landing at a private strip, steaks with tie down ropes can be very useful as well. Don’t forget to take your ropes and chocks with you when you leave, though. Ropes and chocks which are left unattended can cause problems for airport machinery (plows) and other airplanes.

    Paper and a Pen

    Back to basics! Don’t forget to bring a pen/ pencil and something to write on to keep track of clearances and frequencies.

    EAPIS/ Boarder Crossing Procedures

    If you are planning to fly across the U.S. Border, you will need to have filed the proper paperwork and make sure to bring along your passport/greencard. If you want to fly into Canada everyone on board the airplane is required to have a passport.

    Basic Tools

    You never know when you may need a screwdriver or some pliers. Having a small toolbox which you can throw in the airplane could be a life saver.

    GPS

    If you have a GPS, make sure that your data base is up to date.

    Camera

    Pretty self explanatory…but, don’t forget the camera charger!

    Currency

    Look through your pilot logbook and the airplane logbook and make sure that everything is up to date. If you need to get an IPC or a BFR done before you leave, give yourself some buffer time in case you have to reschedule.

    Other Considerations

    Sometimes it makes sense to go to a larger airport despite having to pay additional fees and higher gas prices. Often, if I am traveling at night or after regular business hours, it is worth the extra expense to know that there will be assistance available should I need it. It also isn’t always necessary to get a hotel…there are airports such as Noble County, Ohio (I10) that have beautiful campsites available on the airport. If you like camping, it can be a fun alternative to shelling out the cash for a hotel and rental car.
    Camping out next to the airplane can be a fun way to spend the night.

    Finally, I like to take the airplane out for a short flight and make sure that everything is working properly before I bring the family and get everything loaded up. (Plus, it’s a perfect excuse to go for a little joyride.) I’d much rather find out that the battery is dead or the plugs are fouled when I have time to fix the issues. If possible, do your test flight on a day when your maintenance shop is open so you can get any problems addressed immediately. If you haven’t done much cross country flying or if you are a little rusty, ask a flight instructor or another pilot to look over your planning. There is also nothing wrong with having an instructor or experienced friend come along on the first few trips until you become more comfortable doing it on your own.

    In my opinion, cross country flying is one of the most rewarding things a pilot can do with their certificate. The view available from the window of a general aviation airplane is so different than the one you get out the window of a car or a commercial airliner. If you’re willing to invest the time and money, you’ll get a lot more out of your trip than a few hours in your logbook. So, what are you waiting for….haven’t you always wanted to go to Oshkosh?

  • Building An Airplane

    Randy Vanstory, a long-time customer of Texas Top Aviation, decided in early 2017 to build his own airplane. Randy currently owns a Mooney M20J and has been active in aviation for a number of years.  He took on the Vans RV 10, starting in February 2017.  He’s about halfway through right now, with an estimated completion of mid-2020.

    A completed Vans RV 10

    I asked Randy what gave him the desire to build his own plane.  “I love building things, learning new things, and working on things” he said.  “This satisfies those desires all in one project.”  Randy had a desire to work with his hands, to create something of his own, and building an airplane put several of his passions together in one project.

    Lots of pilots out there dream of building their own airplane in their garage.  There is a certain cool factor to putting together an RV or a Lancair in a garage, then trucking it out to an airport, attaching the wings, then flying a personal creation for the first time.  An airplane unique to you, since there isn’t one quite like it any where else.

    That’s the beauty of a homebuilt.

    Here is a link to Randy’s build video done by Kobalt Tools.
