Snappy Posted May 20, 2023 Posted May 20, 2023 (edited) Are / were there official procedures for flying land-based instrument approaches like TACAN approaches or PAR? In case weather didn't not permit the classic visual/overhead break pattern. Specifically, when to configure the aircraft at which point on the instrument approach or which speeds to fly on the different segments. Couldn't find anything in the HB manual under procedurs and don't have the actual NATOPS. Thanks a lot in advance, Regards, Snappy Edited May 20, 2023 by Snappy
Bremspropeller Posted May 21, 2023 Posted May 21, 2023 (edited) TACAN approaches are normal non-precision approaches which you would fly off the approach charts in the kneeboard. The charts are either included with the map or they're dowloadable for most airfields. I think I've seen a DOD-style PAR approach plate for Cecil Field - so I'd hazard a guess they're field-specific procedures as well. Here's Gwangju, ROK (Jepp Chart) - it uses both ASR and PAR for opposite runways. Note there's no actual 'procedure' besides the mised approach instructions, as you're being vectored onto final by radar and you're talked down by radar as well. ASR is without altitude guidance, so it's basicly your NP PAR with higher minimums. Note there are no circling minimums for PAR, which is straight in only, but for ASR there are. Hope this at least partially answers your question. As a rule of thumb, if you're configured and on speed around the Final Approach Fix, you're going to do okay. Unless you're a Space Shuttle: Edit: Here's a nice PPT with non standard approach procedures that also covers ASR and PAR quite well: https://www.slideserve.com/gasha/non-standard-approaches Edited May 21, 2023 by Bremspropeller 1 So ein Feuerball, JUNGE!

I am familiar with the Tacan / Instrument approach procedures and how to read the approach charts and fly them. I was really more looking for how things were officially done in the real aircraft in regards to speeds and configuration. Being fully configured and on speed/AOA passing the FAF sounds sensible. You can freestyle the other parts of course ,but it would be interesting to know how the aircraft is operated authentically, which speeds were typically flown on the initial approach segments or during racetrack patterns while descending etc.. Still thanks for putting in much effort into such a detailed reply! kind regards, Snappy 1
