744: Can't get CLB 1 or CLB 2 to kick in on climbout....

Featured Replies

I am still in my testing and familiarization phase with the Queen and hand flying quite a bit. I am experimenting with derated t/o and climbouts. I find that using the FMC to enter PERF INIT data and the THR LIM page for setting power, although I can depart normally and also with assumed temp, doing a TO1 or TO2 at light weights, when the time comes for climb thrust and I hit THR on the MCP, I always get CLB power. I never get CLB 1 or CLB 2 power even if I have selected such settings with the relevant LSK right clicks. As a result, the N1 will surge from, say, TO1 or TO2 to full CLB power which is not what I want.Does CLB1 or CLB2 only work when VNAV is engaged and activated using the AP and flying a departure on a flightplan? Appreciate any info/advice on this, thanks!Jonathan

In reality I think the "THR Switch" should function as you describe. Perhaps PMDG will "patch" it?-Paul :-)

Ah, the joys (and risks) of reality. Whoever imagined we'd get to a point where we need to patch reality? I love it!I guess the fix for now then is that for manual departures, I must have the THR LIM page open at thrust reduction height and manually hit the LSK for CLB1 or CLB2 when ready to do so ? (probably....)Jonathan
