Q

Left Turn Tendencies

A

-Most Prominent @:
-High Power
-High AOA
-Low Airspeed

1.Torque:
-newton’s equal and opposite rx
-only rolling

2.Slipstream:
-vorticies of air moves around plane, hitting tail, yawing left

3.P-factor:
-propellor
-down faster than up

4.Gyroscopic Effect:
-propellor
-a force felt on a spinning disk is felt 90 degrees in the direction of rotation

Q

Load Factor

A

Actual load supported by wings divided by the total weight of the airplane
-effect of gravity on the plane in a bank
- 60 degrees = 2 G’s

Why is it dangerous?
- overloading the plane is not good
-increase stall speed

Q

Va

A

Maneuvering Speed:
-@ or below we will stall before structural damage occurs, across only 1 axis of motion
-speed is based on weight
