PVT

A)The airspeed does not increase
B)A spiral is caused by a stall
C)The g-loads increase
D)They are the same thing

g-loads increase. A spin is where the plane is still in a stalled state even though it is falling toward the ground; therefore, the airspeed remains below a stall. In a spiral dive the plane is still in the pilot's control and the airspeed will increase. As the speed increases, the bank angle and the g- load will increase.
