Scud Running

ByHank Gibson June 2, 2015

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.

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?

I Learn To Speak Seaplane

ByHank Gibson February 9, 2019February 19, 2019

From the time I started flying, I have always had the dream to learn how to fly a seaplane.  As I learned in November, it’s actually learning to land a seaplane, and the veterans call them floatplanes.

ProMark Aviation at the Burnet Airport (KBMQ) offers a weekend float plane course that is high on fun and low on stress.  The school has a Piper PA12 Super Cruiser on amphibious floats (amphibs as I was corrected at one point.  I mean, if you’re going to fly a seaplane, er, floatplane, you have to know the lingo) that will land and takeoff on water, but does little else with ease and grace.  At 150 HP with those big floats and all the associated rigging hanging underneath the airplane, you are lucky to get to 500 feet before you get to your destination.

We weren’t working on setting any speed records.  I was learning the lay of the water.  I learned about the step, the keel, pumping the floats, how to read the water, currents, ducks (yes, ducks and birds are important to know about when you are flying low on the water), buoys, docking, and ditching.  Step taxiing was fun as you are basically at 3/4 throttle screaming across the top of the water just below flying speed.  It’s the best way to taxi a seaplane (truly, it is.  You get more air in your engine, you can see better, and you are moving.  Just don’t try and turn sharp).

Floatplanes also don’t have any shock absorbers, so the higher the wave, the more you get knocked around, so wind velocity and, in turn, wave height is very important.

A very important nuance of an amphibious floatplane compared to a straight floatplane (one that doesn’t have wheels that come out of the floats), is at one point, you want to make sure your gear is down for landing (runway landing) and at another, you want to make absolutely sure your gear is up for landing (water landing).  If you land wheels down in the water, you will capsize, 100% of the time.  Thankfully from my good instruction, I did not capsize.

Ken Wittekiend, my instructor, and I spent the majority of the weekend landing and taking off on Lake Buchanan (I was informed by locals it is pronounced “Buk-cannon”, not “Bue-cannon”), which is more open and therefore has more waves.  We did one landing on Inks Lake so my kids could see me land, which they thought was the best thing since cheese sticks.

There is a check ride at the end of the training, but, as Ken reassured me, it’s the most fun check ride you’ll ever have.  I still hate check rides, but that one I think I hated least of all.

I hope someday I can put my floatplane skills to practice, but for now, I can vouch that I now speak seaplane!

Shock Cooling in a PA46

ByJoe Casey October 25, 2018

We’ve all heard it said…”reduce the throttle by no more than 1-inch every minutes to ensure you don’t shock-cool your engine”. Does this advice apply to a PA46 engine? Can a PA46 engine (Lycoming 540 or Continental 520/550) really be shock-cooled? How should the engine temperature be managed?

Metals expand and contract with temperature, and the various metals in an air-cooled aviation engine expand and contract at a different rates. Shock-cooling supposedly occurs when the engine changes temperature quickly and the different metals in the engine cool (and therefore change shape) at different rates. When the change occurs dramatically supposed scoring, rubbing, and marking of the metal can occur, which can cause catastrophic results.

So, let’s back to the original question…can a PA46 engine suffer shock-cooling and should a pilot operate the engine so as to avoid shock cooling? Simply put, I’ve never seen nor heard of any piston PA46 engine suffer shock-cooling. In 5000+ hours flying the piston PA46 and 16 years of flying/managing/training in the Malibu/Mirage/Matrix, it simply has not happened to me nor anyone I know. Does it mean that it cannot happen or has never happened? No. But, it is certainly not a prolific threat to our fleet.

Should the owner/pilot operate the engine with a cautious eye cast toward the potential of shock cooling? Well, sort of…but, let’s flesh this out. My suggestion is that a pilot should operate the engine with conservatism in movement of temperature, but only because this is a good operating practice with any machine, and any flying machine is (by definition) not “overbuilt”. And, there are many ways to change the temperature of the engine…not just by reducing power. Here’s a partial list of ways to cool your PA46 engine:

• Reduce power: Obvious…yes. When the engine produces less power, less heat is generated. Reducing power in a piston engine will almost always result in less temperature.
• Lower the nose: By descending (and leaving power in a cruise setting) the airspeed will increase and cool the engine.
• Enrichen the mixture: Fuel has a cooling effect on the engine, so the richer the mixture the cooler the engine.
• Lower the landing gear: Yes…you read that right…engine cooling will occur when you lower the landing gear because more air will flow over the cylinders. Notice the landing gear doors on the PA46 have air louvers. Air flows into the engine nacelle on the front, passes down through the cylinders (along with the oil cooler, intercoolers, and other components) and then out the louvers of the closed gear doors. When the landing gear is lowered the “back door is opened” and a LOT more airflows over the cylinders.

My suggestion is that a pilot only perform ONE of these actions at a time when beginning a descent. This suggestion was presented to me by Chad Menne (Owner, Malibu Aerospace) some time ago and I’ve operated engines this way ever since. If you are at a higher altitude and simultaneously reduced the power, lowered the landing gear, started a big descent, and enrichened the mixture in one flail swoop, I think there’s a chance that your engine would suffer some negative effects that could be called “shock cooling”. So, when you do start a descent, pick one “cooling action” to accomplish at a time. I’m sure you’ll not hurt your engine.

Simply put, shock cooling is not a huge factor in the PA46 community, and a PA46 pilot does not need to be overly cautious. The “one inch per minute” rule may apply in some other airframes, but in the PA46 world it is not applicable.

Joe Casey’s aviation story began in 1990 with his first flight near Nacogdoches, TX in a Cessna 172. From lift-off, Joe knew he would have a lifetime passion flying just about anything that will leave the ground…He was completely hooked.

Along with being an FAA Designated Pilot Examiner (DPE), Joe is an ATP/CFI-AHMG and Commercial Rotorcraft/Glider Pilot in the civilian world and also a UH-60/AH-64 Pilot-in-Command/Instructor/Examiner Pilot in the US Army Reserves.  His passion for the last 19 years, however, has been the PA-46 Malibu/Mirage/Matrix/Jetprop/Meridian. Has has amassed over 6,500 hours in various PA-46 airframes and believe it to be one of the finest flying machines available for the serious cross-country pilot with an eye for efficiency.

Now, Joe has flown more than 12,200 hours in just about every imaginable environment. Whether providing initial/recurrent training in the PA-46’s, TBM’s, instructing in NVG’s in a UH-60 Blackhawk, flying the King Air series of airplanes, giving tailwheel endorsements, or taking kids flying for the first time, he simply loves flying machines and the people who fly them.

Lightspeed Headsets and Modern Audio Panels

ByHank Gibson February 1, 2018February 9, 2018

I love Lightspeed headsets.  They are very comfortable, durable, and reasonably priced.  Plus, when you call Customer Service, you are actually talking to someone who works for the company and knows what they are talking about.

One thing to watch out for with Lightspeed headsets is the Mono vs. Stereo option.  On the Zulu 3, there is a very small control panel underneath the battery compartment to change from Mono to Stereo.  If you have any kind of modern audio panel, you will definitely want to do this.  Here’s why.

I was flying in a Cirrus SR22 G5 last fall with a Garmin 350 Audio Panel.  Everything worked fine talking to the ground and tower controllers.  Once I took off and was switched to approach, everything went quiet.  I could hear the approach controller, but couldn’t transmit.  I thought my headset had bit the dust. There was another set in the plane that I switched to, but I thought the transmit function of mine was out.

I sent the headset back to Lightspeed for repair.  The headset was still under their 5 year warranty, which is really nice!  I got it back a few days later, plugged it in to another Cirrus, and still had nothing.  I was getting frustrated, but then a light went on.  One of my colleagues had mentioned something about mono and stereo in the Lightspeed.  I popped the batteries out, flipped the switch over to stereo, and wa-la!  Everything was fully operational.

If you get Lightspeed headsets, you’ll want to make sure it is set on Stereo, as they all come from the factory on Mono.  If you get a PFX, there is an easy access button on the side of the battery unit to switch from Mono to Stereo.
