Asymmetric thrust and pitching moments due to thrust...

Recommended Posts

Hi you lucky guys already playing with this new kid in town :-)

 

An aspect that has always kind of disappointed me in previous PMDG releases, namely the NGX and the 777 ( with the "SAS" systems disengaged ) is the behaviour under asymmetric thrust situations.

 

I wonder how it is now modeled in the 744 ?  How are the rolling / yawing moments reproduced when an engine failure occurs ?

 

How about the pitching moments with thrust changes specially on landing configuration ?

SAS? Not sure if that is Boeing terminology. Certainly haven't seen it in any flight manuals.

 

Could it be possible you are comparing the handling characteristics of a <5700kg airplane type to a sophisticated airliner?

 

Also, how can you be certain that the 737, 777 and potentially, the 747 engine inoperative handling behavior is incorrect?

 

Genuine curiosity and not being mean, or intentionally mean.

SAS - hence the " " around it :-)

 

737 - LevelD Sim experience.

747 - Pilot reports

Haha careful, you might get chased outta town :)

 

Thank you for the rest. I'll leave it to PMDG to answer.

Pitching moments : well try it :) Whack the throttle and see what it does

 

Yawing tendency with engine out : yes we augmented FS dynamics internally (by code) in order to match required rudder trim settings between FS model and real world and LVL D sim session ex[erience.

Ok!  Looks VERY promising!  Thx for the prompt answer.
