I've been having issues with manual elevator control in the NGX ever since it was installed, and after extensive testing I've come to the conclusion that the issue is with the aircraft itself.

 

I always perform a flight control check as part of the 'Before Taxi' checklist and often find that the elevator responsiveness is sluggish. With the SYS page open on the lower CDU it is clear that sometimes the elevator doesn't reach it's full range of travel and moves at a slower rate than the control inputs. This issue is intermittent, but can sometimes be remedied by moving my CH controller through it's full range of motion a few times. Every time this happens, I also switch to the CH control manager and test my yoke, it shows completely normal range of travel and responsiveness.

 

There is also an issue whereby after the autopilot has been used, the elevator will not reach it's full range of travel (according to the SYS page on the CDU). When the yoke reaches either full back or full forward travel, the elevator will jump to the neutral position. Again, a check of CH control manager shows that this behaviour is absent.

 

The result is that manual flying after the use of the autopilot is much more difficult than after takeoff. During the approach the aircraft is 'mushy' and not as responsive. 

 

Out of interest, loading a default FSX aircraft also clears this issue, therefore I have to assume that the problem is with the NGX itself. 

 

Has anyone else noticed this issue, or know of a remedy?

 

Many thanks,

You say loading a default FSX aircraft clears the issue. How are you loading the NGX, do you have it as your default flight? That can cause problems. It's best to have an FSX default aircraft in the default flight to initialise the NGX correctly.

 

It could be a hydraulic system problem in the NGX. Make sure all pumps are on and quantities are full.

Thanks for the tip, I'll give this a go and see if it resolves the issue.
