How do I use TACAN and ILCS?

TACAN Limitations:

Cannot transmit voice

DME equipment is an integral part in providing slant range up to 399.9 NM with an accuracy of 2 miles or 3% of the distance, whichever is greater

Cone of confusion:

Exists where TACAN azimuth information is not available

The "cone" varies from 60° to 110° wide

TACAN DME and ID signal will be received and station passage will be noted by minimum DME

Although narrow at low altitudes, this "cone" expands to about 18 NM across at 30,000'

Because of the size of TACAN cone of confusion, holding on a TACAN will always be established using DME

Standard Service Volume applies (T, L, H stations):

SSV defines the interference free reception limits of unrestricted NAVAIDs, which are usable for random/unpublished route navigation

Reception may be possible beyond the ranges, however interference from other stations on the same frequencies may cause 40° off bearing lock-on

40° off bearing TACAN pointer lock-on error:

Locking on to multiples of 40° from the desired radial due to inherent operating functions of the older crystal controlled receivers

Solid-state electronics in the T-45C should preclude this problem from occurring

Re-channeling the receiver and tuning back to the original station may remedy the error

Failure to lock on:

Misalignment of equipment

Worn aircraft control box

Re-channeling the receiver and tuning from the opposite direction back to the original station may remedy the error

Co-channel interference:

Receiving signals (DME, azimuth, identifier) from more than one TACAN station due to the relationship between aircraft's high altitude and station locations

Ah perfect! Thank you very much!
