What is the maximum oil pressure during takeoff?

The correct answer is based on the operational limits set for the T-6A regarding oil pressure during takeoff. The specified maximum oil pressure range for the T-6A is 90 to 120 PSI. This range ensures that the oil system maintains adequate pressure to lubricate the engine and its components effectively during this critical phase of flight.

Understanding why this range is defined is important for operational safety and engine performance. Adequate oil pressure is crucial for cooling the engine and preventing wear or damage during high-power operations such as takeoff. Operating within this specified range allows pilots to ensure that their aircraft is functioning optimally and safely while managing engine stress.

Other options provide different ranges that do not align with the specified limits for the T-6A. Maintaining oil pressure outside the defined range could indicate a potential issue with the engine's lubrication system, which could lead to significant operational hazards if not addressed.
