Which procedure should be followed to gain a better altitude during a waveoff?

To gain better altitude during a waveoff, pitching for Vy (the best rate of climb speed) is the appropriate procedure. Vy is specifically designed to provide the maximum altitude gain in the shortest amount of time. When executing a waveoff, it is essential to maximize the climb performance to respond effectively to the situation and ensure a safe ascent away from the ground.

By pitching for Vy, pilots ensure that the aircraft is generating the optimal lift-to-drag ratio during the climb, which directly translates into improved climb performance. This helps establish a positive climb rate as the aircraft transitions from the landing approach back into a safe maneuvering altitude.

In contrast, leveling off and circling would not necessarily offer immediate altitude gain and could compromise safety in certain situations. Increasing the rate of descent contradicts the goal of gaining altitude, and reducing throttle to maintain altitude would not facilitate a climb but rather keep the aircraft at a steady level, further emphasizing that optimal performance is key during a waveoff. Thus, pitching for Vy is the strategy that ensures effective altitude gain in this critical phase of flight.
