Most difficult instrument approaches

The most difficult part of an approach like that to Arcata on a stormy night is the winds are usually blowing at 40-60 knots. I did an approach in there a few months ago with winds blowing at 40 knots and my ground speed was around 87 knots.

WTF is that for? An F16???!!! No seriously! What is that for? How the heck is it flown and WTF are those dotted lines? :D

Actually, yeah. Most "HI-something" approaches are designed with high performance jets like fighters in mind. The military teaches them, and civilians generally don't fly them very often, but there is nothing out there prohibiting a civilian from flying them. The dotted line is the ground track that they want you to fly. "HI" procedures are generally a little bit convoluted and usually require a pretty steep descent gradient. The basic idea is to take you from a high cruise altitude to the runway without having to do an enroute descent. Most of them are simple tear-drop shaped things, (sort of like the "base turns" that the ICAO uses in some foreign countries) but some of them have weird restrictions, dead-reckoning legs, and all sorts of oddities.

This is a fun one to have a student get out while in a sim session. It isn't that hard to actually fly it but the looks of it can be overwhelming at first.

College Station, TX (KCLL): Localizer Back Course 16

I've shot that approach before. They didn't let us do the Arc. We were radar vectored to intercept the back course and off we went.

All of you DFW folks should check out the new ILS approach that just came out for Mineral Wells (MWL) in the newest edition of the TERPS. It's super funky. I would post it up but I can't find it anywhere on the net.

DCA LDA/DME 19. At minimums.

I'll second this one. Better get configured early and make sure you're lined up with the correct runway before descending to land!

Heres the approach I was talking about. http://myairplane.com/databases/approach/pdfs/00658ILD31.PDF
 
I've revewied the approach plate and I can't see what's so unusual about it!

Kind of caught me off guard that you go out on the VOR radial, procedure inbound on a VOR radial, and then track the localizer at glide slope intercept.

That just seems weird to me. It really through my student for a loop the first time we flew it.

threw :D ...just kiddin'...just kiddin'
 
I always liked the ILS 1 at DCA followed by a last minute "can you circle to land on 33?" call from the tower. The approach to 19 is just as interesting.
 
I would have to vote for

HGR VOR 9 this is a fun approach due to the steep descent and a poor VOR signal.

ASE LOC/DME - E the missed approach is quite fun :sarcasm:
 
Flip the switch on the procedure turn outbound. Gotta be easier than flying a LOC outbound, eh? :)

Yeah but that's for KROW...an airport open to the public.

Dotted line is the procedural track portion of a jet penetration.


Check a few of the Distant Early Warning stations and their IAPs. They have the warning of "Successful Go Around Improbable" due to their location. The field is usually located on a mountaintop side, with the runway at 7% or greater. Air Stations with these warnings include Earacksen AS, Cape Newenham AFS, Cape Romanzof AFS. There's restrictions as to what kind of aircraft can operate out of these stations as well as crew experience. Normally, you'll only see C-7/C-123/C-130 aircraft.
 
I've found any LOC you do partial panel really challenges your scan, especially if there's a big altitude loss from the FAF to the MAP.
