Terminology
« Reply #25 on: April 25, 2006, 10:36:22 AM »
Most airliners, I believe, climb at maximum thrust, or a derated thrust still close to maximum thrust. Maintaining 250 knots below 10,000ft. To maintain 250 knots, the rate of climb varies. (Pitch controlls airspeed style).

after 10,000ft the Flight Management computer would influence the indicated airspeed to an optimum level. 300KIAS would be roughly the area for most aircraft for this stage in climb, give or take 30KIAS. It would maintain this untill transition to Mach speed controll.

Climbing at an increaced rate while in this mode would cause a reduction in speed. Increasing speed requires a reduction in climb rate, but no change in thrust would be required unless levelling off and maintaining a certain speed.
