What is a requirement for using maximum performance technique in certain scenarios?

The use of maximum performance techniques is particularly crucial in emergencies or situations where conditions are less than ideal. When facing an emergency, pilots must ensure that they can achieve the best performance possible to climb or maneuver effectively, and utilizing maximum performance techniques can be essential in those scenarios. This approach allows pilots to extract optimal performance from the aircraft, ensuring a safer outcome when confronted with challenges such as obstacles, adverse weather, or equipment failures.

In contrast, while the presence of passengers, the comfort level of the Second-in-Command (SIC), or making techniques mandatory for all takeoffs and landings may seem relevant, these options do not account for the essential context in which maximum performance techniques are most vital—namely, emergencies where quick decision-making and superior performance are necessary for safety.
