So, there I was, in my Hornet, doing my usual (blast off, tank, 2 CASE-1’s, 2 CASE-2’s, lather, rinse repeat) and I thought I’d intercept an [arbitrary] arc for a TACAN approach for fun.
I’ve seen these done a zillion times in years past (million years ago) on my RADAR, but never really learned how you’re supposed to fly them. I asked a co-worker once (he was a CFI on a B-1900 or something like that) but long ago forgot what he said…
Just a quick ‘hack’, from those of u that have done it for realz. I just kinda WAG it: point the wing at the TACAN and watch my DME, adjusting as necessary to stay within +/- 1nm, til I see the needle ‘twitching’.
Essentially what you said, but getting to and maintaining a specific arc, and calculating when to start your turn on and off the arc can get a bit complex. Should all be laid out in there.
4.5.3.3. To roll out on a desired heading, calculate a lead point that is approximately one-third the angle of bank used in the turn (e.g., if making a 30 degrees bank turn, begin roll
out at 10 degrees of heading prior to the desired final heading)
Yeah… Haven’t flown an ARC in years, but I remember it was rather entertaining. When I learned about it in flight school I was amazed! Such a simple way to get to the lead in!
Now every approach have got T points. Meh.
