Left Turning Tendencies / Aircraft Stability (Check Ride Prep)

Front

What is Torque?

Back

As the airplane's propeller turns to the right, the plane rotates around the longitudinal axis to the left.

-on the ground, especially on takeoff roll, the rotation puts pressure on the left landing gear

Front

Gyroscopic Precession

Back

-Mostly applies to tailwheel aircrafts

-The propeller acts as a gyroscope when it spins.

-This results in a force on the right side 90 degrees pushing the nose to the left

Front

Sprialing slipstream

Back

-The prop wash from the propeller spirals around the airplane in a corkscrew pattern, eventually hitting the vertical stabilizer

Front

P-Factor

Back

Descending propeller creates more thrust than the assenting propeller at a high aoa creating yaw

Back

initial tendency of the aircraft to return to the original state of equilibrium
