Can you confirm that the 727-200 ( version with the INS ) does not have the ability to track a back ILS, unlike later 737s etc. As the airport I was landing at ( Marston, Kent UK ) does not have a vor/dme on the airport it was difficult to align - is it a case of landing visually or have I forgotton to do something.
I am new to the panel but getting the hang of it

So far as I'm aware .... there's no issues relating to the B727 ILS (or that of any of our aircraft/panels). In fact I've always found the B727's to perform ILS approaches b---e---a---u---t---i---f---u---l---l---y .... for me !
If you're new to these B727 panels then you might like to familiarize yourself with my B727 PANEL INSTALLATION & HANDLING NOTES .... on the ABOUT HJG AIRCRAFT forum page. These notes are intended to help folk better understand and enjoy/get the best out of these panels.

I think the issue was in relation to RWY's that only have one ILS and hence landing from the other side, need to be able to do a so-called back-track on the ILS.
Not a few RWY's does only have the ILS on their main heading, whereas Mike's problem here is that the conditions had him forced to land from "the other side" and not wanting to go visual....
Mike: I'm not too familiar with the INS on the 727, but I do seem to remember that backtracking ILS isn't the easiest of approaches in FS. althoguh the basic issue is that you just have to turn your head up-side down when reading the headings .... (more or less) ....

It's been a while since I flew in the real world, but as I recall, typically you only see Localizer backcourse approaches (not ILS backcourse). Of course there may be a few of those out there. I'll ask an airline pilot friend of mine.

Yes, ILS Backcourse's are localizer only.

Indeed, confirmed with an airline pilot friend here in the US.

Just as an aside, I'm not aware of any 737 (real or FS) that has a difficulty flying a back-course ILS approach as long as you're not expecting it to fly the non-existent glideslope no matter what equipment it has onboard. If it's getting vertical guideance, then you're not flying a back-course approach, you're flying a front-course ILS or you're flying an RNAV approach, something that an INS and most FMS aren't capable of providing.

Just a note Chris, Mike was asking about the 727 not the 737, not that I think your answer would be any different though  |

Dan, he made a reference to "later 737s", which is what I was addressing as I read it to mean that the early model 737s had a problem like the 727. |

A link to a nice page explaining LOC Backcourse Approaches: stoenworks.com/Tutorials/ILS%20Back-Course%20Approaches.htmlBasically, tune the LOC Frequency. Turn your Course on the HSI to the opposite direction of landing. Turn in towards the LOC Backcourse and make sure autopilot has B/C selected. Do no select NAV, do not select APP, do not select ILS. However, in some aircraft, if you turn the course on the HSI to the landing direction of the runway, and have the LOC tuned, the flight director system will automatically sense that it is a Backcourse, and you can select NAV mode on the flight director / autopilot and it will fly the approach. I suggest trying B/C mode first, with the course on the HSI set to the opposite of the landing direction. -Andrew |
