still no success with glidescope capture

Recommended Posts

hi can you tell me when landing the GS captured properly?i am having problems with my planes, add ons and stock MSFS planes capturing the GSthe needle comes down, the ALT button goes off, the engines rev up, the speed increases, and the plane takes a dip,never to recover and i end up landing on the grass at the MM or in the sea short of the runway...

.. how about "GS", "capture" ...and search in archives too. I hope you can figure out how to use search options.Michael J.

One thing that usually works for me is to be set up, gear down, trimmed and on speed for FINAL approach prior to glideslope capture.Capture the glideslope from below in level flight. Dont wait til in close, as it usually cant hack it. Most of the time it works great for me. The only problem now is watching out for those killer ILS's out there:)Hornit

Hi,I have a 99% succes ratio on capturing the glideslope and making succesful ILS landings on everything from default Cessnas to the most complex Category 3 Autoland Heavy jets. 3 very brief rules of thumb:1) Make sure you are centered on the localizer as far out as possible. 10 miles or more is great. This usually means making your descents at a HIGH vertical speed (2000 feet per minute or more) combined with a LOW forward velocity...never over 250 kts. This will get you to a low altitude in plenty of time to start your approach many miiles from the airport.2) ALWAYS capture the GS from BELOW. Wait until you start to see the indicator come down and THEN push the approach button. If the indicator hits the center or goes below it, you are out of luck. Timing is everything here.3) Keep your speed up. Even though your calcualtions or your FMC might tell you that your 737 or A320 (for example) should be landing at 135-140 kts, I find that in most cases if I let the speed drop below 150kts, the plane will loose the glide slope, and will not have nough energy to climb back up to capture it again. It is my opinion that this last point is responsible for the trouble that many people have with the GS capture. Landing a little fast seems to have few ill effects, you just get a little more smoke out of the tires!!!!!As others have noted, volumes have been written about this, but I think if you try these three rules, you'll have great success!!!Good Luck,Vonat(PS - actual succsful GS capture illustrated...it CAN be DONE!!!)

yea thanks i will give it a go when i come homethe thing is i tried everything from slow speed to, low fuel, to fast speed, however this time i will get dirty before gs capture, also this time i will press the APP button once i see the GS coming down,but i need to press the APP button earlier so the localiser captures first ?:-hmmm p.s also i havent been centered, so i may have to centre myself first...

Localizer and Approach are two seperate functions. Most if not all planes have two different buttons for this. You first get yourself centered in the horizontal plane by pushing the LOC button once you see your VOR/Localizer indicator start to move towards the center. This ussualy happens several minutes before you reach the point where your GS indicator starts to move down. It is at this pint you push the APP button. You might want to take a quick look in the MS2002 Help section to get familiar with these concepts. There are also some good flight lessons that came with FS with instructors explaining all these things in great detail as you go along.Vonat

thanksbut correct me if i am wrongas i dont have FS2002 at work,but in the default planes there is only the APP button?no LOC button?i know is payware like PIC Phoenix they may be two separate ones

Yep, you're absolutely right. On many smaller planes, the NAV button doubles as the LOC button, so push that one. Be sure you have NAV selected and NOT GPS ...you will usually find a switch for that near the VOR readout.Vonat

ah ha oki never knew the NAV button was also the LOC button,ok so this time i will press the NAV button first for intercept and then APP button for Glidescope intercept and trackingthanksi will give it a go when i get home and report back:-wave

Actually, the APP button will automatically intercept the localiser AND (then) the glideslope, provided you are within reasonable intercept parameters (< 45 degree localiser intecept and under the glideslope to start). Note localiser MUST intercept before the glideslope does.Gary

ok guys it hasnt worked here are some pics1/ has you can see i am getting stablised on the ILS, glidescope is still up awaiting to intercept2/ got the Outer Marker3/ Intercept Glidescope Alt Button gone off4/ Plane takes a dip 5/ See the GS needle, its up, i am too low, plane never recovers and i land on the grass:-hmmm

Well, it's hard to tell exactly what's going on from still pictures, but I do notice two things....one is that your NAV button is not lit at any time. You may be headed in the right direction, but if that button isn't lit, your computer has not locked on to it.Secondly, your IAS is set to 140. I would set it at 150. Even though at the moment your speed IS 150, it must be decelerating to match up with your 140 setting. Allthough the APP button IS capable of capturing both localizer and glideslope, EVERYTHINGS has to be perfect when you push it to be sussceful with that button alone. A good strong localizer lock, a STEADY speed and a CONSTANT altitude. all locked in several miles before you cross the glide slope from below are crucial to your success!!!Good Luck,Vonat

No, the NAV light need not be on. Only the approach light.More flaps and a higher speed should do it.Kitty MercuryCathay Pacific Virtual Pilot (CX252)

Landing with zero flaps? Now I'm yet to see that :) I always land with full flaps :) Unfortunately the FS2k2 G/S implementation is sadly lacking. Most payware panels are fitted with custom G/S, for example the PSS 747 and A320, which stick to it like glue. The PIC is pretty good as well, although it might lose the G/S in bad weather (high cross-winds).

Most of the planes I fly are payware, so I cannot send them to you. I would suggest you practice with the default planes first...the smaller they are and the slower they go, the easier. Try the Cessnas, then the Baron, then the Default 737. If all that works out, you should be able to land anything.Vonat

Hmmm, zero flaps eh? That should have been entertaining! As you've probably realised, you need to ensure that you're pursuing a realistic flap regime and I'd suggest as others have that you stick to one aircraft until you get it right. The default 737 is as good as any other for this purpose.The thing I don't think anyone else has mentioned is weight. If you're trying to land on full or nearly full tanks, you will experience problems with g/s capture for the obvious reason that the a/p is trying to adjust the flight profile from maintaining level flight to a gradual descent. Unless you have a payware aircraft where the weights are factored in realistically and the effects passed to the a/p by a flight management computer (I can't think of too many freeware aircraft that do this), the descent will probably be made assuming a relatively light aircraft. I've proved this to myself many time - take an aircaft and fly a circuit with it, on full tanks and try to capture the ILS. It will invariably dive because it's too heavy for what the default a/p code is expecting. Try it again with no more than about 25% fuel in two tanks. Tell us if it works out any different.Note there are excellent freeware aircraft/panels that do behave as I've suggested without an FMC, but they require that you're aware of the accurate weight of the aircraft including fuel and the need for you to factor that into your approach speed. If that seems a pain, I can only say that that his how the real aircraft are flown. Cheers,AndyEGTR

Right away, I've noted that your speed is a bit too slow with your flap settings.... In an A 319/320 in APR mode, I try to keep it at 145-150KIAS with full flap...remember that the aircraft will lose speed when you start the flare....You don't show full flaps in your shot.... With those settings, I'd come in around 160-165 KIAS, maybe a bit more. As soon as I'd hit and lock the G/S, then I might add a notch of flap which should put the a/c slightly above the g/s...You don't want to get into a situation where the aircraft is chasing the G/S lock. FS will adjust the pitch trim, which will slow the aircraft, reduce lift, and quite often move you further below from the G/S.... You want to lock the G/S at a speed vs. flap setting which will maintain the G/S with only minor intervention from FS's autopilot. If you see the aircraft slipping under the G/S, you want to apply a bit of power, then back off slowly until the G/S stabilizes. But once you have the proper intercept speed vs. flap settings locked into your mind, the G/S will track well.One other issue which can cause a problem.... The APR uses elevator trim to respond to deviations in the G/S.... You may have to increase the aircraft's trim sensitivity to make it a "good g/s tracker". You can add or adjust a line under flight dynamics called elevator_trim_effectiveness, and that can help with the odd problem aircraft.-John

To me.... everything looks okay, and like someone else said, I bet you have way too much fuel. I usually take off with about 30% fuel if the flight is 30 minutes or less. Try thatRick
