MAC262 – ACFT Limits And Speeds Practice Test

PCR (divert) pressure value is which of the following?

70 PSI 80 PSI 92 PSI 100 PSI

Correct Answer:

92 PSI

Explanation:

The idea being tested is the pressure at which the divert path in the PCR system activates. This divert pressure is a deliberate setpoint that tells the system when to switch flow from the primary route to an alternate one. In this configuration, the setpoint is 92 psi. That value sits high enough to avoid nuisance trips during normal operation, yet low enough to divert before pressures rise to unsafe levels in the downstream circuit. If the setpoint were much lower, you'd see unnecessary diversions and potential under-pressurization; if it were much higher, you could push the system toward its maximum limits and risk overpressure. So 92 psi is chosen to balance reliability and safety.
