What is assumed during the Takeoff Ground Run (TOGR)?

During the Takeoff Ground Run (TOGR), it is assumed that all engines are operational. This is crucial because the aircraft needs to perform optimally and safely during takeoff, which relies on the proper functioning of all engines, especially in multi-engine aircraft. An engine failure during the takeoff phase can significantly impact performance and is a critical factor in flight safety.

The assumption of all engines being operational reflects standard operating procedures for takeoff, which prepare pilots for the expected conditions they will encounter. If all engines are functioning as intended, the aircraft can achieve the necessary speed and thrust for a safe takeoff. While factors such as passenger load, weather, and engine performance are relevant in broader contexts, they do not specifically dictate the baseline assumption during the TOGR. This understanding helps pilots to assess performance metrics and manage risks effectively when initiating a takeoff roll.
