In a PEL, if the aircraft is below profile between high key and low key, what should the pilot do?

In a practice emergency landing (PEL) scenario, if the aircraft is below the desired glide profile between high key and low key, the pilot should add power to regain altitude. This action is important as it helps to maintain safe control of the aircraft and improve the chances of making the intended landing area. Adding power gives the aircraft the necessary thrust to climb or at least regain lost altitude, which is critical for ensuring the aircraft is in the correct position to execute a successful landing.

This option emphasizes the importance of maintaining adequate altitude and positioning during the landing approach, which is crucial in emergency procedures. It allows the pilot to assess the situation better and make any further adjustments necessary to successfully reach the landing zone.

Typically, lowering the gear immediately would be appropriate once the approach is stabilized and the pilot is confident in achieving a safe landing. An immediate landing is not advisable without verifying the aircraft's position and ensuring a controlled descent. Completing a 360° turn might place the aircraft further out of position and complicate the landing approach, rather than correcting the altitude issue. Therefore, adding power to regain altitude is the most logical and effective action to take in this situation.
