Question 1

What’s a spin?

Answer 1

It’s an aggaravated stall that results in an autorotation.

Question 2

What’s an autorotation?
When does it happen?

Answer 2

It’s a combination of roll and yaw that propagates itself due to asymmetrically stalled wings. For it to happen, the aircraft must be stalled and have a yaw.

Question 3

What’s the main control surface used in a spin?
What’s the effect of an increase in deflection during a spin?

Answer 3

It’s the rudder, which is used to stop the spin.
It is used to create drag (due to a change in relative wind direction) in order to create yawing moment.

Question 4

What’s the pitch tendency of a T-6B during a spin, based on spin direction?

Answer 4

In a right spin, the nose will tend to pitch down and opposite for the left spin, due to gyroscopic precession.

Question 5

What’s the relation between rotation speed and nose pitch during a spin?

Answer 5

The higher the pitch, the slower the rotation.

Question 6

List the spin recovery steps.

Answer 6

1. Gear, flaps and speedbrake retracted
2. PCL idle
3. Rudder full opposite to turn needle deflection
4. Control stick forward of neutral with ailerons neutral
5. After spin stops, level out and recover.
