Also known as P-factor. A tendency for an aircraft to yaw to the left due to the descending propeller blade on the right producing more thrust than the ascending blade on the left. This occurs when the aircraft’s longitudinal axis is in a climbing attitude in relation to the relative wind. The P-factor would be to the right if the aircraft had a counterclockwise rotating propeller.

A bending of the electromagnetic (EM) wave from the satellite that creates an error in the GPS system.
A personal motivational predisposition to respond to persons, situations, or events in a given manner that can, nevertheless, be changed or modified through training as sort of a mental shortcut to decision-making.
A system composed of three-axis sensors that provide heading, attitude, and yaw information for aircraft. AHRS are designed to replace traditional mechanical gyroscopic flight instruments and provide superior reliability and accuracy.
An aircraft attitude indicator that incorporates flight command bars to provide pitch and roll commands.
The foundation for all instrument flight, this instrument reflects the airplane’s attitude in relation to the horizon.
Controlling the aircraft by reference to the instruments rather than by outside visual cues.
