Help with the glide slope.

the glide slope is 3° in standard some exceptions apply. you can always find your vertical speed by taking your ground speed in knots and multiply it by 5.31 that is your vertical speed for descent in ft/mn to maintain your glide slope. :)

also at about 1000ft agl. you will be able to see the runway. unless very bad visibility. aim for the 2 solid dashed line on the runway. go visual from there.

I’ve already read that. Thanks. But th at topic about the glideslope didn’t really help.

What is agl ? I know that there’s another unit but I forgot it

above ground level. it is different from msl that is shown in altitude meter in hud. if the ground underneath you is a terrain at 1000ft. and you are at 2000 ft msl. your agl is 1000ft.

Judging from some of your questions, I think spending time reading the pilot tutorial may help as most of what you are asking is covered.


Ok as some simple guidelines to help you get started, once you have nailed the basics then you can learn to refine it as you gain more experience.

First of all I would start with a mid size jet like a B737-700 and in settings keep landing aid ON.

First of all start off on SOLO mode when you are on a short final. This will put you in the correct starting place at about the right speed, configuration for landing ( flaps down, spoilers armed, gear down).

As soon as you spawn hit the SP button on your autopilot so that you stay at the starting speed. You should be at about 3000ft AGL (above ground level) inbound to landing, now hand fly down the red boxes towards the runway. Nite that your VS speed should be about -700.

When you get the call out for ‘1000’ then disconnect the autopilot and you will have to control the throttle as well. Aim to keep speed about 135-150 kts ( yes a little fast but ok at this stage).

Just before you land, raise the nose and the cut the throttle, you should gently float down and land!

Now do that 10 times in solo, ( at least) to get the hang of it before heading on line to a deserted airport where you can do extended circuits to build up your skills.

Good luck!


What really worked for me in the beginning is trying to approach as “flat” as I can so I didn’t have to worry about my vertical angle. Then I could focus on aligning myself with the runway horizontally.

When I was close enough to see the runway my focus was to keep the little circle (I don’t know its name) on the runway. The circle tells you where you are really heading - that’s different from your nose direction because of winds. I made small corrections using the autopilot, adjusting the HDG. Not very professional but it did the job and now after a lot of practice I can land 100% manually while aligned with both the glideslope and the localizer.

Make sure you watch all tutorials here, but especially those related to ILS approach.

After you’re good with theory, practice is key. Keep flying and in 50-60 landing from now you should be able to master this stuff.

Good luck and welcome aboard!

Pick a plane and stick to it until you’re experienced enough. Physics differs, so choose the one you know best - it allows you to focus on the landing itself.

How long did it take for you to get better?

How long did it take you to master it?

It took me a long time to get it right. Lots of practice. Like most things in aviation, it doesn’t come easy.

To add onto what @royfr83 said, go find an airport, take off, and set autopilot to hold you at 2,000 feet above the airport altitude (roughly – if your airport is 2,645 feet, you can fly at 4,600 and be ok) and a constant airspeed, maybe 180 knots. Without worrying about your pitch or speed, just like up with the localizer (left/right indicator, in the bottom center) until you’re comfortable with that. Then, fly a long approach, and line up on the localizer. While you’re underneath the glideslope, set your AP heading to stay (roughly) on the localizer. Take off your altitude part of the autopilot. Practice descending on the glideslope until you’re comfortable. Then, put both parts together.

It might take a couple days, but I promise you’ll see improvement. I’m a G4 pilot, IFAE, ATC, 800+ hours. I still use autothrottle on many approaches, and in some cases I’ll use heading and altitude controls. Managing your pitch, heading, and speed all at the same time isn’t easy, but give it some work and you’ll be a pro in no time. Feel free to PM with any questions, and happy landings!

@Cifs don’t give up! You surely can and will master this.

My recommendation for you would be, after watching and reading the tutorials, to…just practice. As mentioned, this is the whole trick: practice, fail, repeat, get better. Start with an easy aircraft, such as the C208 or the Citation. Then slowly move to small airliners.

Keep a good eye on your vertical and horizontal instruments, and avoid over-corrections. Forget the APPR function. If you wanna learn this, it’s better to crash then to ‘cheat’.

I have done about 2000 landings in X-plane, and another 5000 landings in IF, and I still sometimes get them so wrong, that I need to execute a go around to avoid a crash.

Practice makes almost perfect 😀


Thanks for all the tips. Also. If you’re flight is long and you are cruising at possible 10-38k ft when is the right time to descend for your final. And how excalty can you maintain your glideslope on different methods.

you cannot be exactly on the glide slope from FL320. just desend at around 100nm from FL280 at -2000fpm. add 5nm for every 1000ft in your cruise altitude. gardually slow down to 240knts by 10000ft. that should work. try to be at 18000ft when 60nm out. thats the best to contact approach if you have one. :)

In reality most ILS slopes and localisers are only ‘authorised’ for use within 25 miles and 5 degrees.

This is due to radio interference and thus loss of stability of the beam.

Aim to ‘intercept’ the beam from below, halve your ground speed to give you the rate of descent you need for a 3 degree slope (i.e. 180 kts GROUNDSPEED gives 900fpm for a 3 degree descent). As the glideslope indicator comes in from the top and reaches 1 dot above the middle start descending at the rate you’ve worked out. The slight delay in starting the descent will put the bug in the middle. Pitch then gives to speed power gives you change in the rate of descent.

Easy! ;D

Ok, this is a different question, it’s not about landing, but about approaching.

There are apps in the iOS and Android store that can help you calculate your descent rate. Search for ‘descent’ and there’s a good chance you find a few.

In my flightplan, I always try to find a waypoint which is about 20 NM from the start of the ILS cone of the destination airport. This is the point where I want to be at 11,000 feet AGL, to make sure I can gently descent to the start of the ILS cone.
When at cruis altitude, before you start your descent, check your flightplan for the distance between current position and the 11000 feet waypoint. In the little calculator enter this distance along with your current altitude, target altitude (11,000) and your current ground speed… The tool then calculated your descent rate in feet per minute. Works great!

Good advice @azeeuwnl. Let’s be honest we don’t always take the time to make a flight plane in SimBrief or find one in flight aware. This info might help you visualize distances on the map to bettter select waypoints… The ILS cone on the map is 10 miles long. Class bravo airports have three concentric circles around then at 3, 8, and 12 nautical miles. Class charlie airports have two rings at 3, and 6nm. Class bravo have one at 2nm.

Maybe this will help you, it’s much easier to understand…

Always approach the airport at 3,000 feet. However if the airport is for say 609ft above sea level, I would approach at 3,600 feet. Hope that makes since. Now I approach at 200knts in a comercial jet, I then slow down to around 180knts, around 8-9 miles out. This is also around the first two set of flaps (in a Boeing flaps 10 to 15 in an airbus flaps 1-3) around 7 miles out I take the speed down to 160knts, another couple notches if flaps. Then at around 5-6 miles out I hit my final approach speed of 150knts. At 5 miles I ask my spoilers and put my gear down. I am one notch if flops away from full, at 4 miles out I put full flaps in, and turn if the auto pilot.

Now that we learned how to properly approach, the glidespoe will come easy. When you approach at the 3,000 feet, make sure that the little green circle is on the runway. Preferably near the piano keys (the white strips) you will actually touch down a little after the piano keys, but you aim for the piano keys so you have enough time to flair. If you need help with flair PM me. Anyway… descend how ever fast it takes for you to reach the rubway, with the green curser over the piano keys. Remover to watch your speed and your flaps. I’m here for any further questions. Feel free to PM.
