What To Do Once You Have Reached Airport VOR

Sat Jul 27, 2002 7:38 pm

What do I do once I have gone over the VOR without using FSnavigator or a GPS. Say i want to land how do i find the ILS. What do the real life pilots do once they have gone over VOR. I dont know what to do. Could you please give me some detailed help.
Thanks Ryan

You should never pass over the VOR (unless your approach chart says to)...
It's the final fix in your landing patter, usually a non-precision approach. Fly the correct heading towards it and you should end up at the runway.

What you can also do, is just enter the traffic pattern. There are a bunch of easy and difficult ways to do this, but the easiest thing to do in FS, is fly parallell to the runway you would like to land on, but come from the opposite direction, and keep the runway to your left side. You are now in left downwind.

Now, just keep flying and make sure you have the ILS set and so. No, when you are like 10 NM away from the runway (or airport, or whatever), turn to base leg (i.e. make a 90° left turn), and before you 'intercept' the ILS localizer, turn another 45° or so. This should make it easier to intercept the localizer.

Now, when you see the localizer needle moving ('alive'), intercept the localizer and make sure you are aligned with the runway. Of course, watch your glideslope as well. You should intercept the glideslope from below, i.e. flying 'under' the glideslope and then watch the 'glideslope' needle coming 'alive'.

I think this is a pretty nice way to land using ILS, not using vectors, STAR or whatever. Of course, don't get me wrong. I don't know how real-life pilots would do it, but in FS, you're free to do whatever you want, right?

Well Ryan, lets start with a small plane so you can get the hang of an approach and landing...just like real life, you don't start in a 747!
First, taxi to the active runway. I'm going to use Meigs airport as an example because it is the most widely known. For this purpose, lets say the active is rwy 36. This will mean your approximate heading is 360, or North. Take off, and climb to 700 AGL making a climbing left turn to 270 (crosswind leg). Climb to 800 AGL. Now, when you are about 1/2 mile away from the runway, make another left turn to 180 for downwind leg. You should be flying parallel to the runway. Reduce your power so that when you are abeam the numbers, your airspeed indicator is in the white arc. Extend your first notch of flaps, and being your descent. When the end of the runway is about 45 degrees between your tail and wing, make another left turn to 090 for base leg. Finally, make another left turn to 360 to line with the runway for final.
This is the basic landing pattern for all landings, no matter what aircraft. To preform an ILS, tune the ILS freq. to your NAV1 radio. You can turn your OBS course to the runway heading for a reference if you prefer. Establish yourself in the pattern on a downwind leg of the runway you wish to land on. Fly past the runway until your DME reads about 10NM from the airport, now turn to base. Intercept the needle as you turn towards final and use the glideslope to maintain a proper descent. Remember that an ILS approach is only an ILS approach until you see the runway. When you have the runway in site, make a visual approach to the runway.

Usualy you file to the Initial approach fix (which on an ILS is often not the on field nav aid). But, assuming it is, fly oubound on the radial opposite the inbound course for the ILS you wish to fly (using NAV2), with the your NAV 1 tuned to to the ILS frequecy. Once the locaclizer comes "alive", follow that (watch out for reverse sensing!) untill you are 2 minutes from the on field VOR. then turn 45 degrees and fly for one minute. then turn 180 degrees in the opposite direction to intercept the localizer. Turn inbound on the localizer and continue to fly level utill you intercept the glide scope. at this point drop gear, approach flaps, and start down.
When in doubt, one B pump off
