What can occur when operating in the region of reverse command?

When operating in the region of reverse command, increased nose-up pitch indeed results in an increased rate of descent. This phenomenon occurs because, in this flight regime, the aircraft is typically operating at a lower airspeed, where more angle of attack is needed to maintain level flight as the power available decreases.

As the pilot raises the nose to gain altitude, the aircraft may enter a scenario where it requires an increase in thrust to counteract the increased drag and maintain altitude. If there is insufficient power available to maintain altitude with the increased pitch, the aircraft will begin to descend more rapidly. Therefore, nose-up pitch not only fails to produce the desired lift but also exacerbates the descent rate due to the higher angle of attack and the associated drag.

This relationship is crucial for pilots to understand, especially in situations such as go-arounds or low-speed operations, where managing pitch and power requires careful consideration to avoid unintentional altitude loss.
