Use bank angle between 30° and 45° to maintain positive load factors during the descent.

Bottom line

When initiating the descent, a bank of approximately 30 to 45° should be established to maintain positive load factors (G forces) on the airplane. Simulated emergency descents should be made in a turn to check for other air traffic below and to look around for a possible emergency landing area. The objective is to descend the airplane as soon and as rapidly as possible while not exceeding any structural limitations of the airplane.
