Hey guys,

My issue is with initial climb.  I set the FMC fine, import flightplans from PFPX, calculate loads and weights and set the aircraft up for econ climb.  Under FL250 it climbs at around 2000 - 3000 fpm, from FL250 - FL320 it slows to about 1400fpm, but after a certain height it just slows to about 50fpm until I take over myself and force it into a real climb.  I've turned off step climb options in PFPX and the FMC, and the aircraft isn't struggling with speed in the climb (usually .768).  It's not a major issue, just want to know if I'm doing anything wrong here.  Maybe it's a simple fix.

 

Thanks for your help,

-Karl

Karl,

 

Which WX program (Upper winds temps).

 

What is your OAT?

Hey Vaughn,

I use REX2.  The issue happens no matter the wind bearing or strength.  I would estimate -30 to -40 OAT on average(I fly in North America almost exclusively).

 

I have disabled FSInn weather and set FSX to clear skies to reduce weather loading problems.

Karl,

 

Need to be sure about this one.." I would estimate -30 to -40 OAT"

I was not so worried about wind ..

Did you do a screenshot of your panel?

 

FL230 is -30C

FL280 is -40C

FL320 IS -48C

FL360 IS -56C (standard)

I didn't grab a screenshot and I'm currently not in flight.  I'll grab all the required info on my next flight.

 

Thanks for the quick reply!

Ok,

Sounds like a plan.

I used REX3 and ActiveSky2013  , i found out that REX 3c confusing climbing rate on my PMDG 737 . I think it affects badly after injection , nevertheless i like better Active Sky gives better performances results
