Correct time,decent and speed for landing

Can anybody post, as I am experiencing problems when landing with speed,decent,distance to start decent and landing on auto poilet. .

It all depends on the aircraft you are flying especially the decent rate.

If you search on YouTube there a are few good tutorial video’s to help with this thanks to FDS.

I’ve borrowed this from someone and I can tell ya its pretty accurate:

Calculating top cruise altitude:
Formula: Total Route Distance / 2
Subtract 10 from Ans
Divide by 3
Multiply by 1000
Example: TRD: 200nm/2 = 100nm
100nm - 10 = 90nm
90nm / 3 = 30
30 x 1000 = 30,000ft
So cruise at any altitude at or lower than FL300.

Calculating top of descent distance:
Formula: Cruise Altitude / 1000
Multiply by 3
Add 10 (optional)
Example: 30,000 / 1000 = 30
30 x 3 = 90
90 + 10 = 100
Start descent at 100nm out. This provides enough time to descend incrementally and level off at a reasonable speed.

Calculating VS:

Formula: Ground Speed x 5
Add 100 (optional)
For descent: Ans x -1
Example: 500 x 5 = 2500
2500 + 100 = 2600
2600 x -1 = -2600

Don’t you just love math!

could you get VS calculation by multiplying with airspeed?

You must have scrolled down pretty far to find this topic. Please don’t necropost In future :)
