Why do TACANs not have a symbol for compulsory reporting on IFR Enroute Low Altitude charts? I am studying the IFR Enroute Low Altitude legend, and I noticed that all NAV Aids other than TACAN have a compulsory reporting point icon.





They do appear on the STAR/DP legend.


Why do TACANs not have a compulsory reporting point icon on the STAR/DP, but not IFR Enroute Low Altitude?
TACANs are for military use. VOR or VORTAC are the civilian equivalent.  Civilians can't generally tune in TACAN.

This wikipedia article has more details.  https://en.wikipedia.org/wiki/Tactical_air_navigation_system
