What is the maximum pressure differential during ground maneuvering?

The maximum pressure differential during ground maneuvering is indeed 0.1 psi. This specification is important because it relates to the safety and operational protocols of an aircraft while it is on the ground. Ground maneuvering includes activities such as taxiing and preparing for takeoff, where the aircraft is subjected to various aerodynamic forces, but it is not at a high altitude where pressure differentials can become more significant.

In these ground conditions, the minimal pressure differential helps to ensure that the aircraft’s systems, particularly the cabin pressurization systems, operate safely and effectively without the risk of structural damage or failure. Knowing this pressure differential is crucial for pilots and ground crew to maintain aircraft integrity and ensure safety while the aircraft is still on the ground.

Other choices, such as the larger pressure values or altitude measurements, are not applicable in this context since they pertain to different flight phases or characteristics unrelated to the maximum pressure differential during ground operations.
