During an ELP, at what distance should you configure the aircraft for landing?

Configuring the aircraft for landing during an Engine Failure in a Landing Pattern (ELP) at 1 mile from the runway is the correct choice because at this distance, the aircraft is typically positioned to establish a stable approach to the runway. This allows for a controlled descent and ample time to perform any necessary checks and adjustments for landing.

At 1 mile, the pilot can ensure that they have the appropriate airspeed, descent rate, and flap configuration. This distance also provides sufficient time for making any final adjustments to the glide slope, ensuring a safe landing trajectory while managing the energy in the aircraft effectively.

While the other distances mentioned may allow for landing configurations under different circumstances, they do not provide the same level of efficiency and timing that 1 mile from the runway does in standard protocol for ELP situations. This makes 1 mile the optimal distance for configuring the aircraft for landing.
