Taxiways located on aprons may be classified into two types apron taxiways and aircraft parking position taxilanes. Apron taxiways provide a through taxi route across the apron, or provide access to aircraft parking position taxilanes. If located on the edge of an apron, as is common practice, they are often termed apron edge taxiways. Aircraft parking position taxilanes are portions of an apron designated as taxiways which only provide access to aircraft parking positions.
