climb thrust

[Guest squarebush]

With the autothrottles engaged on takeoff, climb thrust engages after barely passing 100 feet. As a commercial pilot, this is dangereous...climb thrust should not engage until 1000 feet depending on airline procedure or a/c.... why is this????

What makes you think you have LEFT TAKEOFF MODE at 100 RA? [h4]Randy J. Smith[/h4]

In the real thing you can set the height at which you want N1 thrust reduction. This is found in the N1 limit page in the top right corner. It may be that you have inadvertantly got 100 in that box if it is in the PMDG FMC that is. Are you 100% certain that it is reducing the thrust. You can tell because on the EICAS it will tell you what THR mode you are in eg TO/GA, CLB, CRZ etc. or R-TO, R-CLB for reduced thrust operations. If the EICAS still says TOGA then you are still in TOGA. perhaps a screenshot would aid fault diagnosis.Hope that helpsKris

Shortly after rotation at approx. 100 ft ra, the autothrottles change mode from "TO" to "CLB" and the engines rollback to climb thrust....this is shown just above the N1 indication. I didnt see anything pertaining to this in the fmc under n1 limit or other...

Ms/Mr SquareBush,On page 2 on the TAKEOFF REF page you should have the setting for thrust reduction altitude. It should default to 1500 feet but you sure seem to have it set to 100 feet.Oh, and please read the forum guidelines topic pinned near the top. You are required to sign your posts with your real name. ThanksHope it helps,

Ah thats where the darn thing is! I knew it was somewhere in the U10.5 FMC but couldn't place it. We lowly U-5 users don't get such luxuries although thankfully we are slowly being dragged into the 20th century as U10.5 is phased in during hanger inputs.. .suppose I'd best hit the books! Kris
