Jester,
Are you hearing the morse code identifier correctly?
If you are then it could be a few other things.
1) Firstly, you might be too far away from the ILS beacon to get a proper fix. Open the GPS and wait until you are 10nm away from vectors and then change to NAV.
2) You might be too high which would stop the ILS display functioning properly. When you intercept the ILS approach, you should be below 3000 feet and above 2500 feet. I personally choose around 2800 feet to intercept it.
3) You might be too fast when intercepting the ILS beams. If you are flying the default 734 then you should be at around 160 KIAS when intercepting.
After you have checked all of the above, look at the HSI and you should have 2 axes (the horizontal and vertical axes) with 'directions' to the runway threshold.
Hope that helps  _________________ Click below to support FSF:

Well it was awesome thanks 99, I got a "Nice Landing" I was a little off center when I landed and I used reverse thrust below 60 knots whitch cost me 300 points but hey I am not complaining, I am still in the learning stage and I am happy, compared to what happend to me yesterday.
thanks 99

Nick,
Glad to hear you had a nice flight Keep practicing, and your landings will keep getting better and better  _________________ Click below to support FSF:

sorry one more question, How come I have to switch to NAV when I am 10nm out? I am just wondering because I seen FSPX reports that say
-50ftpm? are they on glideslope or am I just being an idiot?  _________________ slow is smooth, smooth is fast

You switch to NAV (from GPS) if you are going to engage the APP button for the approach, until 200 feet. If you are flying visually then you don't need any of the ILS techniques - just use the PAPI.
I am confused as to the connection between the GPS/NAV switch and the touchdown vertical descent speed
Could you explain a bit more please?

Sure, Sorry I couldnt reply sooner, What I mean is this I see people saying that their decent rate is -146.9FT/M ( as seen below)
Report:
Flight Distance: 20 Nm Landing Speed: 118.92 kt
Time Airborne: 00h20:05 Landing Touchdown: -146.9 ft/m (kiss)
Flight Time (block): 00h31:14 Landing Pitch: -1.66°
Time On Ground: 00h12:54 Landing Weight: 5180 lbs
Average Speed: 62.22 kt Total Fuel Used: 64 lbs
Max. Altitude: 4386ft Fuel Not Used: 786 lbs
So My question is How do they know when to start their decent and what are they following, ( How do they know when they are decending to fast or not enough, kind of like when you are on glideslope and it tells you to decend or climb.) ? or is it just instinct?
Maybe I have explained it better this time if not I will eventually find out.
Thanks for the help!!

The landing touchdown speed is the rate at which your landing gear actually touches the runway - this doesn't have much to do with your approach angle (to a certain extent). You could follow a 6 degree glideslope (very steep) or a 1.5 degree glideslope (very shallow) and still have a touchdown descent rate of -100fpm, so landing touchdown speed is irrelevant (to a certain extent) to the approach angle.
If you want to know how do you know when you are supposed to be descending from cruising altitude, say FL350, then have a look at this post:
http://flyawaysimulation.com/postp16545.html&highlight=#16545
In the real world, for commercial aircraft, the FMC controls the Top of Descent (TOD) and the rate of descent.
If you mean in smaller GA aircraft, then you use your instinct. You are unlikely to be flying at above around 11000 feet so it makes the judging of descending quite a lot easier.
Once you get to the runway, you can either use the PAPI / VASI lights to descend, or the ILS or any other type of approach that tells you the correct glideslope, or again, you can judge it visually in which you use your experience and intuition to descend.
Hope that helps - if not, come back  _________________ Click below to support FSF:

| I can never get the autopilot to line the plane up with the runway... Is there something I'm doing wrong? I went through all the steps.. |

Check these points...
- Have you got the NAV/GPS switch set to NAV
- Are you at the right height
- Are you adhereing to ATC vectors
- Does the runway have ILS
- Have you engaged the APP mode
- Have you set the correct ILS frequency in the NAV1 radio and identified it by morse code
-Have you set the correct course
Hopefully that helps  _________________

Well when you turn it on are both localizer and glide slope active??
Sometimes people may think glide slope is on when it isn't because if localizer is available before glide slope the glide slope will stay in the "perfect glide slope" position
Also it works much better if you are approach it from underneath
Make sure that your altitude is less than about 4000ft, and your speed no more than 200 knots
Also have your airplane reasonably pitched before you go and switch on APP, so it won't sway down jerkily |
