How can the landing altitude be manually set?

The method for manually setting the landing altitude involves selecting the "MAN" option located on the pressurization panel. This allows the flight crew to take control of the pressurization system and manually input the desired landing altitude, ensuring that the aircraft maintains the appropriate cabin pressure as it descends. This capability is important during flight operations, as it enables pilots to adapt to varying atmospheric conditions and maintain passenger comfort.

Using the cabin pressure switch primarily adjusts the overall cabin pressure and does not specifically set the landing altitude. Autopilot settings cater more to flight control during cruise phases rather than directly influencing cabin pressure or altitude settings. The flap adjustment panel is unrelated to cabin altitude management and instead focuses on the aircraft’s aerodynamic characteristics during takeoff and landing phases. Thus, selecting "MAN" on the pressurization panel is the correct and effective means to manually set the landing altitude.
