What must pilots flying the RTRL procedures ensure about their aircraft?

When pilots are flying RTRL (Runway Takeoff Runway Length) procedures, they need to ensure that their aircraft can lift off before reaching the specified takeoff distance for safety and performance reasons. This distance is critical because it is calculated based on the aircraft's weight, the runway's length, elevation, and other environmental factors. If the aircraft manages to lift off before the designated distance, it demonstrates that it has sufficient thrust and performance capability to safely ascend, thereby reducing the risk of accidents during takeoff.

This ensures compliance with safety regulations and optimizes aircraft performance during the takeoff phase. Adhering to these specified criteria helps pilots maintain control and minimizes the risk of runway overruns or other performance-related issues during the crucial takeoff maneuver.
