How many crew members are required to be on the flight deck at all times?

The requirement for two crew members to be present on the flight deck at all times reflects established aviation safety standards. This rule is in place to ensure that there is always a qualified pilot and co-pilot available to manage the aircraft’s operation, especially during critical phases of flight such as takeoff and landing. Having two crew members allows for better monitoring of instruments, communication with air traffic control, and the ability to assist each other in emergencies. Additionally, having a second pilot enhances decision-making capabilities, as they can provide input and share responsibilities, which is crucial in maintaining situational awareness and overall flight safety.
