Hello, Guys!

 

I always use ILS to land a plane. Problem is that my vertical diamond shape comes top to bottom near landing instead of going bottom to top (as every one say that this should go G/S diamond from bottom to top) while ILS landing.

 

I've landed hunderds of airplane on FSX but by top to bottom Glide Scope. Look at my plan, I ususally fly B747 and near about 15nm away from landing, I keep my airplane at 3000ft altitude and 200Knots speed. I keep my flaps full at this time. When plane detect G/S, then it itself own come down and I keep speed 160Knts, then plane lands successfully.

 

But I'm not happy by this top to bottom Diamond shape icon, I want it should go from bottom to top. So how can I do this? Please help me. See given pictures also and tell me what error I'm doing?

 

I would be grateful to you.

 

My Method is in this picture:

 

 

Everyone says, do like this,

 

The glide slope should be intercepted from below. That is why the diamond moves down to the center as you approach the glide slope. The diamond shows you where the GS is relative to your airplane.

 

If the diamond is on the bottom it indicates you are too high and above the glide slope. It is very difficult to intercept the glide slope when too high.

Not sure if I understand your problem: Am I right that you want the glideslope indicator come up instead of down?

If this is the case, you'll never be able to land on the ILS with the AP on, because this would mean that the G/S is below your plane's vertical position, and thus the AP will never be able to intercept it.

I understand you've managed to land your plane on ILS quite well, so why would you want to change anything about this? Your way seems to be the correct one, anyways. Whoever told you, that the G/S indicator should come from the bottom of the PFD was wrong.

 

Reagrds,

Flo

Bill has it spot on, whatever aircraft you used before displayed the G/S incorrectly

Not sure if I understand your problem: Am I right that you want the glideslope indicator come up instead of down?

 

Yup, You are pretty right. Can you tell me why you didn't understand me? 1- Due to my weak English 2- Something else?

 

If this is the case, you'll never be able to land on the ILS with the AP on, because this would mean that the G/S is below your plane's vertical position, and thus the AP will never be able to intercept it.

 

Then, how can I do that G/S should be intercepted by plane at right time? From Below to Up? Means, how can I level my airplane vertically with G/S?

I want to do same as a real-World pilot does. Therefore I want G/S Diamond must be intercepted from below.

The glide slope should be intercepted from below.

 

Ya, I think you are right but how to do this?

OK you are right. But you please understand what I'm saying. I'm saying, if it's at the bottom then it should come to the center from bottom instead of remaining there. How can I do this?

Can you tell me why you didn't understand me?

It was mainly the arrows in the two pictures that made me think, I might get you wrong. I only figured out their meaning after I've posted my first reply.

It actually seems you got confused a bit: The vertical diamond represents the G/S relative to your aircraft, and to intercept the G/S signal you have to be below it. Thus the indicator has to be above the center (i.e. the G/S is above your aircraft)! If the glideslope were below your aircraft's vertical position, you'll have to disconnect the AP and manually capture it.

To sum it up: Everything's right, as long as the diamond is above the centerline, but even in realworld, the G/S indicator starts moving from the top downwards. The way you did it until now is just the right one.

If you look at approach plates for your destination, there are always 2 important points. The initial approach fix (IAF) and the final approach fix or point (marked via a cross). The FAF is almost always at an altitude of round about 3000' AGL (Edit:for a standard 3° glideslope). If, for example, the rundway threshold is at 1000' MSL, the altitude for the FAF is likely to be 4000' MSL in the charts. If you are stabilized on your final course you have to descent to that mentioned altitude for the FAF. This ensures that you capture the G/S from below. The diamond shows the position of the glideslope beam. If the diamond is above you, you must be below. If you're at the stated altitude of the approach plate, youre doin it right to intercept the glideslope at the right distance from the touchdown zone.

autopilot, Hirschi is correct. If you are at the correct altitude at the FAF you will be at or slightly below the GS. You then fly into the GS and start your decent. At this point you can lower the gear and set the flaps for landing. If you are using the autopilot you also press the approach button when the diamond reaches the center.

 

Here is a picture that may help. The horizontal bar is just like the diamond on other airplanes.

 

 

Hope this helps you understand what you are seeing.

Nice picture. It's a thousand times better to explain it that way than with words. First I thought to add a draw in my post. But then I remembered my drawing skills ^_^

Guys! Please look at these pictures and tell me, are these two good landings? If not, then please tell me errors?

Looks very good. Good catch of the G/S. Stable Approach. Passengers would sleep like babies.

BTW, if you encounter VMC during your approach, its no fault to switch A/P and A/T off and fly the approach completely visual when the airport is in sight. Firstly, reallife pilots do that, too. Secondly, why sitting in a simulator only to simulate flying within, too? Another plus... flying visual means 70% outside view. So you see the beautiful scenery

That's indeed how it should be, but I agree with Hirschi, flying the approach manually is way more fun. (But as far as I remember, you fly using only the key commands, which makes it much harder to hand-fly an aircraft, but I can tell you, it's still possible. I did that a long time, too, but two years ago I tried flying with a cheaper joystick, and that is really much easier!)

 

Flo

puh, with key commands. Reminds me of the good old racing games without a wheel and broken keyboards keys because, you know, the harder you press, the better it brakes

Haha you used DLH as an example nice!

Thanks All Guys! for helping me. I'm grateful to you all.
