What is the maximum differential pressure for the CRJ 200?

The maximum differential pressure for the CRJ 200 is indeed 8.7 psi. This figure is critical for maintaining the structural integrity of the aircraft during flight. Differential pressure refers to the difference in pressure between the inside of the aircraft (cabin pressure) and the outside atmospheric pressure.

Exceeding this maximum limit can pose risks, including compromised structural safety, as the aircraft fuselage is designed to handle pressures within certain parameters. Therefore, the specified maximum differential pressure is an important limitation that pilots must adhere to for safe operations, especially during climbs and descents when pressure changes are most significant.
