Touchdown! Greaser!
Two opposite ILSs, one with a wavy ILS, the other unusuable inside the threshold (has Cat II on ILS 23), and an obstacle on the NW side; part time tower that contols the TDZ & CL lighting....

Another reason to brief completely and be pretty sure the approach is a make, or to have an alternate means on board. Of course you could "estimate the MAP hold" just like if the core navaid goes down inside the IAF...but out to the south somewhere there is a 7400 foot MSA....

And speaking of Misseds, my all time favorite is attached. Sorry about the lousy copy. It's from an OLD publication. But at least here there are two ways to identify the Missed hold. You just can't get to it anymore if you lose the rnwy on the fly visual segment.

Is this just for when the tower is closed, as it is right after the bit talking about increased visibilities when the tower is locked up for the night?
Gee, I can't imagine why circling not authorized NW of the field
It looks like an obstruction farm up there.
Does the CAT II ILS gain you very much here? I know you get 50 feet better, but you can't ride it down to the threshold. What does "RA192" mean in the altitudes and visibilities chart? It is military in the parentheses, but I don't remember seeing that "RA" term before.

If radar is out and you don't have any ability to legally ID the missed approach holding fix then you are SOL for this approach. There is an alternate missed approach procedure for 23 but I can't for the life of me remember what it is. Of, course if you're NORDO it don't much matter, I guess.wsuffa said:On the ILS-23, look at the missed. ADF is not required for the approach.

Jim the field always has radar as long as the radar site is operational. When KTRI tower closes Atlanta center takes over the airspace and simply remotes the TRI radar to a scope in Hampton, GA. They have the same picture and video map.grattonja said:I may be missing something here, but on the NOS chart I have, in the notes section, there is a small note in caps saying ADF or Radar required.

grattonja said:"Successful go-around improbable". Nice. Should have an exclaimation point after it. "Don't do this missed approach" might be a better way to say it.
