What happens if an engine is lost after S1 in a split marker scenario?

In a split marker scenario, if an engine is lost after S1 (the decision speed), it is crucial to recognize that the aircraft has reached a point where it may not safely abort the takeoff without potentially compromising safety. The loss of an engine after S1 can result in continued acceleration that was not adequately accounted for before reaching this speed.

Understanding the dynamics of a multi-engine aircraft during takeoff is essential. At S1, the pilot must consider the aircraft's performance capabilities and thresholds. If the aircraft continues to accelerate after losing an engine, it may not have been fully prepared for that scenario, leading to insufficient power or performance awareness to maintain safe flight. Therefore, recognizing that runway acceleration may not have been adequately accounted for is key in mitigating risks associated with engine loss and ensuring proper decision-making during crucial phases of flight.
