Concept
Main Engine Cutoff: the commanded shutdown of a launch vehicle's first-stage main engines when predetermined conditions (altitude, velocity, fuel state) are met, marking the end of powered flight and enabling transition to coasting phase.
Main Engine Cutoff: o desligamento comandado dos motores principais do primeiro estágio de um veículo de lançamento quando as condições predeterminadas (altitude, velocidade, estado do combustível) são atingidas, marcando o fim da fase de voo propulsionado e permitindo a transição para a fase de coast.
