Hi Guys,

Firstly, well done on the plane, it's fast becoming a very usable aircraft. One thing I'm struggling with though is the flight director indications on takeoff, particularly the pitch bar. It never commands a pitch to maintain V2 - V2+20. Below example from today, I'll give as much info as I can:

Aircraft - PW2037
Airport - KATL, 27R/M20
Weather - 210/5, 24C
FMC - TO, derate to 46C, speeds 146, 149, 151, accel height 1000
MCP - EPR 1.39, V2 151, LNAV armed
FMA - EPR/TO/TO

Rotate at 3 degrees per second, initially up to 15 degrees. However the flight director commands a pitch of about 9 degrees. If I follow this command, the speed just increases to well beyond V2+20. Only after I engage VNAV at accel height do the FD commands become sensible again. I find that the problem gets worse the higher the derate.

Any ideas? Or any other members experience anything similar?

The FD on take off is supposed to give guidance for V2+15 but CS  have not bothered to implement it.
It has been mentioned as a bug but nothing has been done or will be done about it.

Seems an odd thing to choose not to implement at a rather crucial phase of flight... Shame. CS, any comment on this? Surely it can't be too complicated to stick in a hotfix...

It's not a bug but a missing feature: https://www.captainsim.org/forum/csf.pl?board=y757_suggest

I can't see it in that forum. Is that a hint that you'd like me to put it in there?

I think so!  ;D
