After the G-warm, what should the PCL be set to at altitudes above 10,000 feet?

• A. 90%
• B. 100%
• C. 75%
• D. 85%

Answer: (B)

At altitudes above 10,000 feet, the Pressure Control Limit (PCL) should be set to 100%. This setting is crucial as it ensures that the aircraft system operates within optimal parameters under lower atmospheric pressure conditions typically found at higher altitudes. Setting the PCL to 100% provides necessary thrust and system performance, which is vital for maintaining altitude and maneuverability in an environment where engine performance can be adversely affected by thinner air. The choice to maintain the PCL at this level reflects an understanding of the aviation safety protocols that help manage engine and system performance. The higher PCL setting is essential in compensating for any loss of power that might occur due to the decreased air density, thereby enhancing the aircraft's reliability and efficiency during flight in such altitudes.
