Please tell me the steps you use to capture the ILS. Here's what I do, but mine's flawed because my "Altitude Hold" switches off and I get erratic and deadly behavior from the aircraft. 1. I'm in GPS mode (direct to) an airport. 2. I program the runway I want into GPS. 3. I start my descent at proper time. 4. I set "heading" to intercept the ILS, and go from GPS mode to Nav. mode. 5. When I switch on APP. mode, my Altitude Hold goes off and the plane goes into a deadly dive. 6. I have to switch Altitude Hold back on, but then the APP. mode doesn't AUTOMATICALLY switch off Altitude any more.What am I doing wrong procedurally? Exactly "What" and "When" do you move from GPS to NAV and how do you guarantee that Altitude stays on WITH the APP. mode until it's automatically shut off? This is driving me crazy. It used to work well for me in FS 2002. Stan

Maybe here? topic #196192:-)

How do I get to that topic? Is there a search procedure for finding a topic #? Stan

Just checking... you may know that it's essential to be BELOW the glide slope before turning on APP in order to properly capture it.AS far as getting to that topic, you could cust and paste it into the "id=" portion of the address bar in your browser window.Alex M.

Please show an example or discribe where to cut and paste the topic number. I tried the search box several ways and got nothing. Thanks.

Please tell me if you need a better discription.Thanks, Mark.I am trying to find the post number, topic #196192, as listed above. The attachment dose not work.

Stan, first, let's simplify this. Don't use GPS for a flight. Take off from an airport that has at least one ILS approach. For the heck of it, I suggest KCHO (my home airport). Set your NAV1 to 111.70 with your OBS set to 031. Depart using runway 3. Do not turn on A/P. Fly out from KCHO for about 1 mile and then turn right to the ricip of 210 degrees. Engage A/P with a HDG of 210 and ALT = 3,500. This will put you on a right pattern hand pattern. Climb to 3,500 feet MSL during your downwind leg. Maintain 3,500 feet until you are below the GSI. Now turn right to 300 degrees. Hold that heading only a short period and start your descent to 2,200 feet. If you wish, use PVE as a marker to turn. If you use PVE, you will be able to approximate your next right turn to final. When you do turn, you should be less than 30 degrees from 031. Maintain a less than 30 degree approach to the centerline, and turn on APP. You should now intercept both the glide slope and ILS and be on track for an instrument landing at KCHO. If you look on the map, you will see PVE is the line up VOR for 031, and serves as the altitude reference point for the glide slope (2,200 FT MSL if memory serves). Give that a try and let us know how you did.

G'day Stan,You are too high! ie you are above the glide slope when you select APP.1.2.3.4.5. Intercercept the localiser when you are about 20 miles out. Make sure that by 15 miles out you are at 2400 ft. Set altitude holdSet APPROACHat approximately 10 miles out you will then capture (standard 3 degree) the glide slopeand altitude hold will automatically disengage.Cheers,Roger

Thanks everyone,I will try to practice the procedures recommended by some of you.Perhaps I am too high when I click on APP. Thanks again. Stan

"Intercercept the localiser when you are about 20 miles out. Make sure that by 15 miles out you are at 2400 ft."20 miles is generally way too far out for a standard approach. At a lot of airports, interception at less than 10dme is very common.If you wanted to go 15 miles out, 2400ft seems a bit low. I would suggest you would want to be about 2000ft QNH at around 7 to 8 miles not 15, with which the G/S will take you down to.

G'day Tim,The figures I quoted were not in any way meant to be standard. They were just figures that I felt would give Stan the time to set up the aircraft and capture the glide slope to a sucessful landing. I simply felt that he was intercepting the localiser way too high/too close. ( above the glide slope). I'm looking at the approach chart to Brisbane as I write.intercept the localiser at 2500ft 14 nautical miles out and then capture the glide slope at 2500ft and 10.5 miles out.Exact figures will vary from airport to airport.I hope Stan has success.Cheers,Roger @YSSY
