View Full Version : Climbing Rate on flights
03-24-2003, 11:47 PM
I have been trying to climb to 33,000 ft+ but for some reason I keep on slowing down, and when I get close to that point, my plan stalls because I lose so much speed. At what rate should I climb at, and what flap settings with a Boeing jet. Also, in MelJet 777s how do you walk around virtual Business Class??

It depends on the aircraft you use, but a good rule of thumb is to climb at 250kts-2500 to 3500fpm until 10,000ft, then reduce your climb to 2000fpm and increase your speed to .71 or .73mach.
As for Meljet, go to anticyclone.com and download active camera.
I hope that helps.

There are 3 main things that affect this in flightsim:
1 Amount of fuel
2 Air pressure (QNH/Altimeter)
Basically after about FL 150, set your airspeed to M0.78.
You will notice your airspeed gradually decrease as you mentioned so compensate for this by gradually reducing your rate of climb.
You will probably find that if you are carrying a lot of fuel you may have to reduce to about 300-400 ft/min as you approach FL300.
As far as reaching FL 370 or higher is concerned, in the real world the pilots have to wait unitl they have burned off enough fuel to get up there, as the aircraft simply wont do it.
Hope this helps best regards Gareth.

Flaps are only used for take-off. Once you are established in climb, the flaps are retracted and are not used for climbing to cruise altitude.
you can get the climb schedule from the flight manuals.
You can get them for various Boeing and Airbus a/c from here:
You are probably flying to slowly and need full climb thrust and a reasonable climb angle.
You did not say which you were interested in.

Do not use the climb rate hold function of the autopilot, actually do not care too much about the climb rate at all.
For climb basicly bring your plane to a positive pitch, then let the autopilot controll the IAS (250 below 10000 ft, approx. 300 above). The autopilot then will automatically adjust the climb rate to speed, weight and altidude.
This way is also much saver as it protects you from stalls and/or overspeed.
There is an excellent tutorial how to fly a DC9, written by an real world SAS pilot on http://www.bahnhof.se/~classic/
The basics of this tutorial are valid for any jet.
