Good luck!

1. 1) Angle of attack is:

   You got it. According to the Airplane Flying Handbook, angle of attack is the acute angle between the chord line of the airfoil and the direction of the relative wind.

2. 2) What speed is the top of the airspeed indicator green arc?

   You got it. The maximum structural cruising speed (Vno) is the top of the green arc.

3. 3) In a spin:

   You got it. Both wings are stalled in a spin. As the airplane rotates around the vertical axis, the rising wing is less stalled than the descending wing creating a rolling, yawing, and pitching motion.

5. 5) Maneuvering speed (Va):

   You got it. Maneuvering speed increases as aircraft weight increases. This is because aircraft at higher weights need to fly at a higher angle of attack at a given airspeed to produce enough lift for level flight. Since the aircraft is at a higher AOA, it will more quickly reach the Critical AOA if a full, abrupt control movement is used.

6. 6) Ground effect is caused by:

   You got it. Ground effect is a reduction in induced drag, caused by a reduction in downwash and wingtip vortices when your aircraft is approximately 1 wingspan or less from the ground.
