Most pilots know that way back in 2010 the FAA retired the phrase “Position and Hold”. Instead “Line Up and Wait” came into usage, indicated to an aircraft at a towered field that they are to taxi onto the runway, line up for departure, and then wait until takeoff clearance is given.

I have been a CFI for 10 years now and a simulator user for much longer than that. I am frequently asked if flight simulators are just games or if they can really teach someone to fly. Continue reading “Can a simulator teach you to fly?”
Recently I was flying a Piper Arrow at 2500 feet in turbulent air. I was carefully maintaining my altitude with pitch and trim changes. It was a bumpy ride but it was nice watching the puffy cumulus clouds pass by overhead.
Then I began to notice my indicated airspeed was changing despite my unchanged engine settings. First, my speed would be up about 10-15 knots for a minute or so, then it would drop back down for another minute. The next minute it was back up.
Why was this happening?
I thought about it for a few minutes. The engine RPM and manifold pressure were constant, and my altitude was constant.
This could only be caused by updrafts and downdrafts! Yes, the same turbulent air that was creating those clouds was pushing the plane up every time I passed under one.
You can imagine my plane flying in that mass of rising air, and me correcting almost subconsciously to maintain altitude. As the air mass rises, I need to pitch down to stay at the same altitude. This is as good as descending as far as airspeed is concerned.
These updrafts are what glider pilots use to stay airborne and even climb without an engine. A single-engine plane is far too heavy to stay aloft on the updrafts alone, but they do offer us free airspeed which can save on rental or fuel costs.
But how do we take advantage of them?
First, there is terrain: When you have any kind of terrain plan to stay on the upwind side as much as possible. As the wind reaches rising terrain it will rise to go over it and this rising air provides a great updraft that you might be able to take advantage of by altering your course just a little.
Second is cloud streets: Puffy cumulus clouds are formed in rising air so alter course slightly if it will put you under some cumulus clouds. It may be bumpy but if you are between clouds the air will generally be descending to replace the rising air under the cloud. Glider pilots look for cloud streets, which are long rows of clouds that can provide an updraft over a very long distance.
Just think like a glider pilot and consider how the air around you is moving. Tailwinds get all the attention when looking for bonus performance from the environment, but a nice updraft can help any aircraft to go just a little bit faster for the same power.
Taxiing an airplane is easy to learn once you get some muscle memory in place.
You may already know this, but for most airplanes, you taxi with your feet. Some large planes have a tiller but that is another story for another day. Your foot controls consist of rudder pedals that will control the rudder and, for many planes, also directly control the nosewheel steering. Continue reading “Taxiing An Airplane”
Taking off in an airplane is a fairly simple process, especially compared to landing. But this easy task can be filled with danger, especially because of complacency.
“Just throttle up and pull back!”
It might be easy to think of take off this way, but don’t lose your focus because it’s not hard to make a mistake that can pull the tire off the wheel or leave you stuck in the mud at the side of the runway. Continue reading “Takeoff”
