At what altitude and airspeed should the Low Key position be established in the ELP?

The correct altitude and airspeed for establishing the Low Key position in an Emergency Landing Pattern (ELP) is 1,500 feet Above Ground Level (AGL) and 120 Knots Indicated Airspeed (KIAS). This configuration is crucial for maintaining adequate energy and control during a simulated engine failure scenario.

At 1,500 feet AGL, the aircraft is at a safe height that allows for sufficient time to execute maneuvers while being close enough to the landing runway for effective descent and approach. The chosen airspeed of 120 KIAS provides an optimal balance between lift and drag, ensuring that the aircraft can sustain flight while also allowing for a responsive handling characteristic as the pilot prepares for landing.

This combination allows pilots to accurately assess their glide path and make necessary adjustments while maintaining control of the aircraft. Furthermore, it aligns with standard operating procedures taught in flight training, ensuring that pilots can effectively manage any potential emergencies they might encounter in the aircraft.

In contrast, the other answers present altitudes and airspeeds that either exceed the operational efficiency necessary for the Low Key position or do not provide a safe margin for control and glide performance, making them less suitable for the required task.
