So I brought for you a new tutorial,
on How to descent (For Begginers) in a simple way
here are the steps for descending:-
1. Imagine I am descending to land at TNCM Rwy 10, (I recommend to use TNCM, because it’s easy, approx. on the sea level) and my ALT is 20000ft, you need to multiply the altitude by 3 (I recommend to multiply it by 3.5 (For better experience)), then divide it by 1000
So 20000×3.5=70000÷1000=70NM out of the Destination
Do your all calculations before takingoff
2. When descending, I recommend for the Vertical Speed to be **
3. When you reach 3000ft, keep your ALT 3000 until you establish on Localizer.
Thanks for Reading!
I’ll see if I can do this more often.
This is useful for servers like Free Flight and ATC Playground. Advanced usually has approach, and I only fly when there’s more than 20 pilots on an Advanced server, and there’s most likely Approach at the airport I’m going to. Will keep this in mind for when I do a flight with no ATC involved I guess.
Nice tutorial, but there are some things to clear up.
It would be best to use a higher altitude as an example, but I like your calculations. Even explain about what VS you would use at those higher altitudes.
Depending on the airport is what altitude you enter the localiser.
Anyway, it’s a nice tutorial.
It is for Begginers, and it is just an Example, Anyways I changed it to 20k ft
The Same VS
The example was about TNCM
Great Tutorial for newbies:
rather than multiply then divide I find it a bit easier to just devide the FL by 3. gets the same result.
The VS changes on your alt as well though. As a rough guide I tend to use VS-2500 when above FL100 and -1500 when below 10,000. Its a very rough guide which is fairly close to how it is done IRL. There is a formula for calculating your VS based on your GS, however my brain power cant cope with that at the same time as trying to do other matters!
when I first started I made myself some charts showing how far out from a runway what height I needed to be, the VS needed and the target speed too. Found this a big help and would recommend and new IF Pilots to spend a bit of time with a calculator and piece of paper to work out some basic maths to have to hand.

Is there a particular speed at which we should be descending at?
For A320 Family, B737, B747, B777 and Minimum weight,
From FL200 TO FL150 280knots
From FL150 to 9500ft 200knots
9500 till 5000 170knots
5000 till 3000 160knots
3000 till landing Depends on the aircraft
again it depnds on your height as well as the aircraft that you are flying. Some (like the 777 and other heavys) you need to slow down early, whilst some of the smaller ones can carry speed till much later on.
Again as a rule of thumb I work with the following figures:
Cruise at M0.799 - M0.82 at FL320-FL380
Descend to FL120 with VS -2500 and Speed M0.69 / 260kts
FL120 - 6000 with VS -2500 / -1500 and speed 240kts
usually from about 8000 ft I am slowing right down to about 180 kts when 8nm from runway and can slow down to landing speed and final landing config by reaching 1000ft AGL.
It’s explained in the post above, you also need to mention which aircraft you’re using as each is different
Could you please send me some of your notes
Most of my notes are written in this thread ;-)
Thank you. Will use this when global comes out😉
Mel personally I put my VS to 2000 and I noticed I decend to fast. thanks for the tutorial
Thanks! Exactly what I needed! Every time I descend I’m just about to stall. I’ll admit it, I’m not a good pilot in IF. Probably because I cruise really high up when the regions are really small. When Global is out I’m sure I would be a pretty ok pilot if I do say so myself :)
If you guys have any questions please dont hesitate and ask!
What speed should I descend at in a 757?! Please answer ASAP!
Whatever fits best your FPL, speed and distance to destination.
