What constitutes the "Critical Phase of Flight"?

The "Critical Phase of Flight" refers specifically to the segments of flight where the aircraft is in heightened risk and requires increased attention and focus from the crew. This includes taxiing, takeoff, landing, and all operations below 10,000 feet. During these phases, the aircraft is maneuvering or transitioning close to the ground, where any disturbances or errors could have significant consequences.

This definition underscores the importance of alertness and adherence to safety protocols during these critical stages, as they are when accidents are most likely to occur. For example, during takeoff and landing, pilots are managing the aircraft's speed, altitude, and trajectory, while flight attendants must also ensure passenger safety and prepare for potential emergencies.

In contrast, other phases of flight, such as cruising above 10,000 feet, are generally considered lower risk, allowing for in-flight services and less stringent safety measures compared to the critical phases. Emergency procedures conducted by the crew, while important, do not directly define the operations classified under the Critical Phase of Flight as they can occur during any phase and are not limited to specific altitude parameters.
