Atmospheric pressure has been used to determine the altitude a pilot (or a mountain climber as well) is at since the beginning of the age of ballooning. I find the following Wikipedia excerpt about …

Why is the missed approach point beyond the threshold or sometimes beyond the runway like in the picture below? Is it just to simplify the ATC job or prevent routes from crossing or is it procedural?
|

If you let go of the steering wheel of a (properly maintained) car, it will typically go in a straight or nearly straight line. Would a powered airplane in no-wind conditions do the same thing?

The Commercial ACS steep spiral maneuver calls requires a pilot to fly a descending spiral with power set to idle and maintain a constant radius around a point. The maneuver is supposed to be flown …

Jet engines are by their very nature push-engines, however, most propeller airplanes use pull-engines. Is there an inherent advantage to using pull-propellers except for the increased airflow over the …

This approach shows two sets of minimums that both have vertical guidance with a Decision Altitude (DA). What is the difference between LNAV/VNAV and LPV, and why does LPV have lower minimums?

What is the passenger capacity of an A380, and how many suitcases could it carry?

Can you answer these questions?

As you know, there are two push buttons (MASTER SW and START) related to the APU in the Airbus A320 family. Why there are two pushbuttons? I mean is there any condition in which users switch only one …
