crew is usually startled by the loud bang and the yaw movement, and consequently believes the aircraft is not
fit to fly. Similarly, engine fire warnings have also led to rejected takeoffs above V1. From a system point of view, the engine is certified to ensure that it can sustain an engine fire for a few minutes without affecting the
