"Airplane mode" does not disable GPS... is it safe to use GPS in flight?
22 votes

"It depends". As others have mentioned, GPS is receive only. In theory at least, when everything is operating normally. In practice, some GPS units can fail in a way that causes them to become an ...

Is it true that a soda can or a bag of chips will pop in a plane at high altitude?
12 votes

I can confirm that bagged snacks can pop from the pressure difference. Climbing through 7,000 feet (on our way up to 9,000) in an unpressurized PA32 we heard a quite loud POP. In and out of clouds ...

Why do pilots' masks have more oxygen?
6 votes

Limited space and weight come into play. As well as the fact that sufficient air to keep one alive is not enough for peak performance. The masks for passengers are enough to keep the passengers ...

Is rebooting the computer normal before/during flights?
6 votes

Airliners are more complex, so I suppose it's possible. On light aircraft, I've never heard of anyone having to reboot the computer (glass panel systems). Sometimes we have to reboot our radios, and ...

Do planes have keys?
5 votes

I can only speak to types I have experience with, so: Light GA singles typically have ignition keys. Light GA twins typically do not. When you get to the heavy stuff, I have no idea. :-)

Can pilots fly circling approaches at non-towered airports?
5 votes

I've done quite a number of circling approaches at non-towered airports. ATC clears one for the approach by type (VOR 4, VOR-A, GPS 32, etc). There's no mention of how it is executed or terminates (...

How well can an airplane which is tied down be protected from a blizzard?
4 votes

Our club found that with a good quantity of combined ice/snow (I don't remember how much) our Cessna 172 tipped onto the tail. The Piper Warrior did not for whatever reason. Perhaps wise to add some ...

Why do pilots use airways instead of just "flying direct" every time?

Speaking as a GA pilot flying light airplanes in the US system: On flights in lower use airspace, at lower altitudes, and with the appropriate ATC controls in place (agreements allowing controllers ...

What is propeller / engine sync and how does it work?
3 votes

It's just an automatic system to do prop speed and/or blade location synchronization. On a multi without it, one does it manually by adjusting the prop pitch controls. If the automatic system is not ...

Are there any twin engine aircraft without counter-rotating props?
3 votes

Piper Twin Comanche was available in both configuration, but the most popular one had the engines turning in the same direction. Aztec and Apache are also models with engines spinning the same way. ...

During a takeoff emergency, is it safer to abort or continue the takeoff if either can be done within the available runway?
3 votes

In light airplanes, if you have runway remaining, landing is the preferred choice even once you've taken off. It's not a "ground reject or continue" choice. It's a 3 stage process. Can I reject ...

Will the landing gear work mechanically in case of total power loss?
2 votes

The Twin Comanche I used for my AMEL rating had an interesting mechanism. First you had to disconnect the electric motor, then you stuck this handle into a hole and crank it as far as you can. Then ...

Can you fly a light GA airplane into a major hub? What operational considerations are there if you do?
2 votes

I've flown into Chicago Midway before (as part of my IFR long XC training flight). It was fun. :-) In the USA, if you're IFR they have to take you. They can refuse VFR flights though. However, at ...

What is an optimum engine-out bank angle?
2 votes

3-5 degrees bank angle ("raise the dead"). Use the rudder to keep the skid/slip about half a ball off. That's the standard operating procedure for best performance.

What are the procedures and responsibilities concering landing clearances on ILS Cat 2 or 3?
Accepted answer
0 votes

Around here we'll typically get our handoff right at the FAF (they seem to know exactly when you're busiest and hit you with more workload right then :-) ). The landing clearance comes afterwards. ...

What is the difference between a POH and an AFM?
-5 votes

The POH is the official book of rules for that specific serial number airplane. The AFM is the unofficial/generic one for a type of airplane that may or may not match the one it's in. On occasion ...
