Problems maintaining speed above FL210 - gazpode_l - 02-11-2011
I'm trying to pilot a POSKY B-767. It performs quite well on take-off and seems to climb ok. However, it appears I can only operate it cruising
around FL180. Anything above that I seem to have problems maintaining speed above 210knt indicated speed.
All the other stock a/c and other plane's i've downloaded are unaffected, apart from my vistalines 737-500 which appears to be similarly
affected.
Any help appreciated.

Above FL180 you need to 1) hit the "B" key to turn your altimeter to standard air pressure and 2) above FL180 you should fly a mach speed
not IAS. 210 IAS above transition alt. could be 400 kts GS.

Could it be something that's foul in the aircraft .cfg or air file? If all other aircraft are performing without this issue, I would think there's a
problem in the particular software.

before we start messing with the CFG. id suddgest flying with a Mach instead of IAS
In the FSX default 737 i use 280KIAS to climb between 10000 and 20000. at 20000ft 280IAS is Mach0.60, i then use Mach hold to stay at .60 as i
climb.
the speeds would be diffrent in the 767. but i would assume as simmiler procedure would be used.

i went and read the Pilot Operations manual for the B767 in my Virtual Airline. wich is based on the POSKY 767.
I got this from the Abreviated climb procedure
Climb
inital rate of climb 3000ft/min at 250KIAS to 10,000ft
at 10,000 lower nose and accelerate to cruise climb of 300KIAS or greater, and climb at 1800ft/min
at FL180 reset Altimiters to standered
at FL270 reduce climb rate again to 500-1000ft/min
continue climb to cruise altitude and adgust rate of climb to not exceed Vmo. )you may find that 88%N1 equates into a level 0.80 cruise)
that may or may not help
