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

Front

What is positive static stability

Back

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

Front

What is neutral static stability

Back

initial tendency of the aircraft to remain in a new condition after its equilibrium has been disturbed

Front

What is negative static stability

Back

initial tendency of the aircraft to continue away from the original state of equilibrium after being disturbed

(Contiune to advance into a steeper angle)

Front

What is positive dynamic stability

Back

return to its equilibrium through smaller and smaller oscillations

Front

What is neutral dynamic stability

Back

Tend to continue oscillating with the same magnitude for each oscillation

Front

What is negative dynamic stability

Back

Overtime the occupations will continue to get worse
