What Does TMECO Stand For?

TMECO stands for Time Of Main Engine Cutoff

TMECO, or Time Of Main Engine Cutoff, refers to the precise moment during a spacecraft's flight when the main engines are shut down. This critical event marks the transition from powered flight to coasting phases, such as in orbit insertion or re-entry. TMECO is essential for mission planning and performance assessment, as it contributes to the overall trajectory and timing of subsequent flight operations.
