Taxiways are primarily used for what purpose?

Taxiways are critical components of an airfield, designed primarily for the movement of aircraft to and from runways and other areas like ramps and hangars. The correct purpose for taxiways is to facilitate the safe and efficient movement of aircraft on the ground.

While the other options touch upon related aircraft operations, they don't define the main purpose of taxiways:

• Fueling aircraft usually occurs in designated fueling areas and not specifically on taxiways.

• The calibration of aircraft compasses is typically performed in specific locations away from significant magnetic interference, not on taxiways.

• Parking of aircraft before takeoff usually takes place in designated parking spots or ramps, not specifically on taxiways.

Taxiways are essential for ensuring that aircraft can travel from their hangars or parking areas to the runway for takeoff and vice versa after landing, serving as the ground pathways between these critical operations.
