maintain level flight
Decreasing airspeed
When airspeed is reduced, the vertical component of lift is reduced.
either INCREASE the angle of attack (back pressure) or decrease the angle of bank (roll out a bit).
Lift increases as airspeed increases.
to keep level
vertical lift must be decreased
decrease the total lift by decreasing the angle of attack
or by changing the vertical component when you tighten the turn.
