How to descent in an easy way from high Altitude?
Procedure:-
**P1)**You are at FL300, And you want to descent, do this calculations:-
`30000×3÷1000=90`

Then `90+70NM=160NM`

Descent from 30000 to 15000

**P2)**Then Do this Calculation:-
`15000×3.5=52500÷1000~=53NM`

So at `53NM`

descent to 3000 then wait until establish on Localizer

That is all!

***VS.:- ***`-1700----------->-2000`

Speed:-
FL300:- 0.75M
FL250:- 220k
FL200:- 200k
FL150:- 190k
7000ft:- 170k
3000ft:- Landing speed.

This is for begginers in another way from High alt

Still it’s related and similar. We don’t want topics about every single little thing that can happen :-)
Good tutorial though!

Yeah but beginners or confirmed users, the calcul is the same…!

@R_Jordanian

It’s not, show me that post

Your speeds look low, we often keep our aircraft around 220-240 until near landing when we drop the flaps. (That is unless the STAR says different).

That is for begginers, if they started doing this then they will be familiar with the IRL procedure

@R_Jordanian :

Hi There,
there is an easy thumb rule for descents, that is important to know for pilots and ATC Controllers as well:
subtract the current altitude from the target altitude, eg
30000ft - 10000ft = 20000
divide the result by 1000 and multiply with 3 and you will get the miles
20000 : 10000 = 20 x 3 = 60 miles
so you have to start the descent 60 miles away from the point where you plan to be at 10000
IMPORTANT:
descent rate is no less than 2000ft/min
speed is not higher than 280kts til 10…

Quoted from my personal notes I keep…
==============================
When to Descend.
Using trigonometry to calculate …
1mile = 5280ft therefore…
3deg glide = 277ft per mile.
4deg glide = 369ft per mile.
5deg glide = 462ft per mile.
Remember though that airfields quite often aren’t at zero ft, so use AGL or subtract the airport altitude from your actual altitude.
Most approaches will be a 3° glide slope. A quick and convenient way to calculate these in your head is…
If you multiply you…

Why did you have two sames topics ?

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 d…
Is the difference is : for beginner and for confirmed users ?

We’re did you get 70nm from

i need to know for my t/d im landing at KLAX from YSSY and do I still use the same formula if im at FL390?

Generally speaking, most planes can easily make 10,000ft at 30miles from the field if you start at about 150nm out and drop at 1200-1800 depending on cruise.
