Has something to do with the cone of ambiguity, or no-course signal
zone. It gets wider the higher the TACAN aircraft is. There's a chart in the holding pattern manual that shows the distance vs. altitude, and a DME fix can't even be used if it's within the specified distance, because the TACAN-only aircraft won't ever receive it while he's in that cone.

The text "DME or ADF required" is a lot smaller than I'm used to seeing it
and in a different place.. I had just glanced at the chart wondering how one would identify RMN until I found the text. Great chart--thanks for posting it. Max T, CFI Brad Z wrote in message news:NT9rc.85411$536.14236711@attbi_s03... http://www.naco.faa.gov/d-tpp/0405/09743IL33.PDF I haven't come across an approach with two separate missed approach procedures before. Is this even remotely common? I think I'll add this to my instrument students' training regiment due to some additional interesting features- teardrop course reversal, intersection identification using ndb bearings (not using DME), and a lot of stuff to brief. Some of the approaches down here in central VA are pretty boring. |
