The term 'Parts of a Flight' refers to the various stages of a flight from takeoff to landing. The five-letter solution STEPS is an appropriate answer for this term, as it encompasses all the different parts of a flight. These steps include pre-flight preparation, taxiing, takeoff, cruising, descent, and landing. Pre-flight preparation involves checking the aircraft and making sure all systems are functioning properly. Taxiing is the process of moving the aircraft from the gate to the runway. Takeoff is the process of accelerating the aircraft until it is airborne. Cruising is the period of time when the aircraft is in the air and flying at a constant altitude and speed. Descent is the process of reducing altitude and speed in order to prepare for landing. Finally, landing is the process of bringing the aircraft back to the ground.
