whats the most realistic climb rate and for both descent and climb..with an airliner jet? and does real airliners use VOR.. or it is like in flight sim just gps navigation,how it really works? and how do u use in the sim? do u use vor?

airplanes helped me come to my love in USA,airplanes broke us off. how sad it is?

Rate of climb is determined by what airspeed you wish to maintain and the power settings required for different phases of flight.

VOR and NDB is the only way I get around.

Hallelujah - I'd still use the old SBRAZ if there were any which makes us BC's in an age of AD's.

Indeed, it depends on at what speed you want to climb.

Steepest climb is possible when thrust exceeds the drag by the maximum amount. From the so called drag polar, it can be seen that this is at Vmd (EAS), or the minimum drag speed.

Often, with real airliners, the aircraft climbs at 250kias, because this gives constant loading on the airframe.

Just to give you an idea though, for a modern large airliner this would typically result in climb angles of around 10°.

Rate of climb will depend on how heavy you are, particularly as you reach cruising altitudes.

As for descent, if its well planned, somewhere between 1000 and 2500fpm is reasonable ballpark. Put the spoilers out though, and you can get down far quicker.

My tip for obtaining information such as this, is to read the "Aircraft Owners Handbook" for each and every Aircraft before entering the Cockpit.

All the specifications for operating and flying the Aircraft can be found there.

The details will either be included in the Download, or on the Aircraft's Knee-board.

Failing that, it can be sourced on the Internet for each individual Aircraft.

Exactly. Every aeroplane's different (apart from ones that are the same!).
