For TACAN or VOR/DME equipped aircraft, the initial approach fix may be designated by a

radial and distance from a specific TACAN or VORTAC facility. The radial and distance will

be preceded first by the three-letter identifier of the station. To determine what radial and

distance define an IAF for a specific approach, check the appropriate approach plate. Example:

The IAF for the TACAN RWY 7R approach at NAS Pensacola is located on the 205 radial 14

DME from the station and is written as NPA 205014.
