After TO can´t climb or gain speed (nose down pitch atitude)

[tiagoara 0]

Hi everyone!!

 

I´ve recently made a major clean-installation on my computer:

 

• Windows 10
• FSX Steam Edition
• PMDG 737NGX
• FS2CREW 737 REBOOT
• FSUIPC
• EZdok Cam

and some more add-ons that i use such as scenarios, etc...

 

At the beginning everything work fine as a fly the 737NGX, but a few weeks ago i started to have major problems with the 737NGX after takeoff. It happens when i takeoff (Flaps 5 config for departure) and when i´m airborn:

1. positive rate off climb
2. gear up the speed start to raise 160-170 knots
3. engage de AP.

, then aircraft simply does´t gain speed, does´t climb (the engine thrust is set correctly) and the aircraft start to get a negative pitch attitude, never then less IT DOES´T lose Altitude but i can´t climb and i can´t get airspeed (all instruments show correct measures).

 

 

 

 

 

What is more strange is that i disengage the AP and the AT (flying manual) and with full throttle, i trim the elevator, i raise the nose up and the airspeed drops to stall speed, i cant even get close to a clean speed.

 

Does anyone have experience something like this?

 

Thanks in advance.

I've experienced the same.

After submitting a ticket, it was discovered that FSUIPC was causing my problem.

With as wonderful as FSUIPC is, it does some strange things to the NGX.

Doesn't this happen only if FSUIPC is used to operate flaps?

I never tried to assign flaps with FSUIPC so maybe, no.

It is solved!!

 

I´ve followed this tutorial http://support.preci...gative-aoa.aspx and the issue was solved.

 

Thanks everyone specially cbrdriver and scandinavian13.
