The main idea is that aircraft travel between runways and gates along designated movement corridors called taxiways. Taxiways are the paved paths that connect the runway to the terminal ramps and gate areas, guiding planes with centerlines, signage, and lighting to keep ground traffic orderly and safe. The area right at the gates is the apron or ramp, where airplanes park, load, and refuel. The terminal area around the gates is the gate area, which is separate from the movement corridors used to taxi between runway and gate. So the path used by all aircraft to move between the runway and the gate area is the taxiway.

The main body of an aircraft is called the fuselage. This term refers specifically to the central structure that houses the cockpit, passengers or cargo, and connects to the wings and tail. It’s the core shell of the aircraft’s shape and supports internal components, doors, and systems. The other terms don’t fit as the single body. The airframe means the entire structural framework of the aircraft, including wings and tail along with the fuselage. Hull is a term more commonly used for ships and some airships, not for the fixed-wing aircraft body. “Body of Aircraft” isn’t the standard, official name used in aviation terminology. So fuselage is the precise, widely used term for the aircraft’s main body.

Hold short means you stop at a designated hold point before entering a runway or crossing another taxiway, and you wait for explicit clearance to proceed. This protects aircraft on the runway from incursions and helps ATC sequence traffic safely. You’ll see hold-short markings at taxiway/runway intersections—the solid lines indicate where you must stop, and you may cross only when ATC gives you the go-ahead. This is different from instructions to line up on the runway or to accelerate before landing, which are not about stopping at a boundary but about entering or using the runway.

GMT stands for Greenwich Mean Time. It comes from the mean solar time at the Royal Observatory in Greenwich, London, which is tied to the prime meridian used as the global reference line for longitude. The other options aren’t recognized time standards, and Green Mountain Time isn’t a real standard either. In practice, GMT is often used interchangeably with UTC in casual contexts, though UTC is the precise, modern time standard.
