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.

Edit: Plot twist:

They do appear on the STAR/DP legend. enter image description here

Why do TACANs not have a compulsory reporting point icon on the STAR/DP, but not IFR Enroute Low Altitude?

  • $\begingroup$ VOR frequency 108.00 to 117.95 MHz. TACAN frequency 960-1215 MHz. So even when shown, civilian radios would not pick them up. I can't talk to military operations, but I know I can't report a point that I can't tune in. Not even sure my GPS would identify them for me. $\endgroup$ – CrossRoads Apr 29 at 12:44

    $\begingroup$ Keep in mind that the chart legends aren't the end of the story, because they're only the abridged version! If you really want to study the chart symbology, the Aeronautical Chart User's Guide is one of the FAA's best publications ever. $\endgroup$ – Dave-CFII Apr 29 at 12:57

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

  • $\begingroup$ Nope. Military training routes are identified on civilian charts. No TACANs are shown tho. VOR, VOR-DME and VORTAC, but not TACAN. You can see the charts here skyvector.com Military have their own charts. nga.mil/ProductsServices/Pages/… $\endgroup$ – CrossRoads Apr 29 at 12:14
