T-6 GK Flight Characteristics

Question 1

Slipstream Effect

Answer 1

Thrust generated by the rotation of the propeller induces a corkscrew slipstream that strikes the wing root fuselage and tail surfaces with constant force proportional to power setting and airspeed.

Question 2

P-Factor

Answer 2

Effect of propeller - AOA is higher on the downward blade that on the upward blade causing the aircraft to yaw to the left.

Question 3

Torque Effect

Answer 3

Torque reaction acts opposite the direction of propeller rotation. The T-6 tends to roll to the left as a result of torque when power is increased. Also, the aircraft tends to roll to the right when power is decreased.

Question 4

Gyroscopic precession

Answer 4

When a force is applied to displace a spinning mass, the force acts on a plane 90 degrees from that which it was applied. (Right hand rule)

Question 5

Gyroscopic precession: If the nose is yawed to the left, the nose tends to ___.

Answer 5

pitch up

Question 6

Gyroscopic precession: If the nose is yawed to the right, the nose tends to ___.

Answer 6

pitch down

Question 7

Gyroscopic precession: If the nose is pitched down, the nose tends to ___.

Answer 7

yaw left

Question 8

Gyroscopic precession: If the nose is pitched up, the nose tends to ___.

Answer 8

yaw right

Question 9

Adverse Yaw

Answer 9

Thew tendency of the aircraft to yaw away from the direction of aileron input.

Question 10

Adverse Yaw: What creates adverse yaw?

Answer 10

Aileron inputs create asymmetric drag on the wings. Increased drag on the wing-up side cause the nose to yaw towards the outside turn.
