![]() ![]() Well, imagine that VOR approach that is to a VOR that isn’t based on the field, but that you will pass over along the approach path. So, why might you want to do this you might be thinking right now. What this means practically is that a pilot may utilize their GPS RNAV system to actually fly along a VOR approach beyond the final approach fix as long as they can “monitor” the VOR (or TACAN or NDB) on a secondary radio and ensure that the GPS is navigating along the appropriate NAVAID course for the approach. The underlying NAVAID must be operational and the NAVAID monitored for final segment course alignment”. “Use of a suitable RNAV system as a means to navigate on the final approach segment of an instrument approach procedure based on a VOR, TACAN or NDB signal, is allowable. It is worth noting that there is an allowance in the FAA’s Airman’s Information Manual (AIM) that gives the pilot the ability to use the GPS system to “navigate” along a path when they are flying along the final approach segment of a VOR approach. ![]() This doesn’t mean you can’t take advantage of your GPS system to fly the approach more accurately or in manner that integrates more fully with your avionics package and autopilot. Well, the answer might be because there isn’t a GPS approach to the runway or even the airport you are approaching, or, perhaps, some mean old examiner is just making you do a VOR approach on an instrument checkride. Assign fixes based on TACAN or VORTAC facilities only.Flying a VOR approach? Asking yourself why you would do this instead of doing a GPS approach (assuming your aircraft is equipped with an IFR GPS system)? TACAN‐only aircraft (type suffix M, N, or P) possess TACAN with DME, but no VOR or LF navigation system capability.When the unpublished fix is located beyond 45 NM from the NAVAID generating the off‐course radial, the minimum divergence angle must increase ½ degree per NM e.g., 130 NM would require 88 degrees.įixes contained in the route description of MTRs are considered filed fixes. When the unpublished fix is located over 30 NM from the NAVAID generating the off‐course radial, the minimum divergence angle must increase 1 degree per NM up to 45 NM e.g., 45 NM would require 45 degrees.When both NAVAIDs involved are located within 30 NM of the unpublished fix, the minimum divergence angle is 30 degrees.When holding operations are involved with respect to subparagraphs (b) and (c) below, the angle of divergence must be at least 45 degrees. When the unpublished fix is located on an off‐route radial and the radial providing course guidance, it must be used consistent with the following divergence angles: ![]()
