What letters are used to designate taxiways?

Taxiways at airports are designated using letters to provide clear and consistent navigation for pilots and ground personnel. The letters L, R, and C correspond to different types of taxiways: 'L' for the left, 'R' for the right, and 'C' for center taxiways. This system helps in differentiating between parallel taxiways and enhances safety by reducing confusion while taxiing.

Other designations, such as those using the letters A, B, or C, are more commonly associated with runway identifiers rather than taxiways specifically. Similarly, numerical designations such as 1, 2, or 3 do not follow the established conventions for taxiway identification and are generally not used in this context. The letters X, Y, or Z also do not align with standard taxiway designations and could lead to misunderstandings on the airfield. Hence, the use of L, R, and C effectively fulfills the need for clear communication regarding taxiway navigation.
