Final answer:
The procedure for level off during descents involves adjusting the angle of descent to reach a desired altitude and maintain a constant level flight.
Step-by-step explanation:
During descents, the procedure for leveling off in aviation involves adjusting the angle of descent to reach a desired altitude and maintain a constant level flight. Pilots use the aircraft's instruments, particularly the altimeter and vertical speed indicator, to monitor the aircraft's altitude and rate of descent. When approaching the desired altitude, the pilot gradually reduces the rate of descent by decreasing the angle of descent and increasing the engine power. As the aircraft reaches the desired altitude, the pilot levels off by maintaining a constant descent rate, adjusting the pitch and throttle accordingly.
