November 2, 200421 yr I have a question about how the aircraft deals with a reduced tkaeoff and climb. Am I right in saying that above FL150 the aircraft will resume normal climb thrust after having done a reduced takeoff and climb. If so, I haven't seen this action, it looks like mine stays in the reduced climb mode even though the EICAS changes from R-CLB to CLB. The engines just don't seem to spool up to a normal climb thrust.
November 2, 200421 yr Hi,you are right regarding the reduced CLB thrust being automatically cancelled passing 15000 ft. This is stated in th Flight Manual ("Normal Procedures", section "Climb"). For what I remember of my latest flights, I used reduce TO and reduced CLB and the FMC performed flawlessly, increasing thrust levels crossing FL150.
November 2, 200421 yr I guess I have just not been paying enough attention to the numbers. From what I remember, well I know it does switch over to normal climb, but I don't see or hear a big increase in thrust after crossing FL150...maybe it's because it was already at a high thrust setting before leaving reduced climb.
November 2, 200421 yr Mikkel - The A/T or EEC will gradually increase the thrust from R-CLB to reach nominal CLB thrust at 15000 feet. You will not hear or see a big increase in N1 values.Hope it helps, Mats JohanssonPMDG Flight Test Dept | Asus Z270-A | Intel i5-7600K @ 4.8 GHz OC/H2O | nVidia Geforce GTX 1070 8GB OC/O2|
