Has anyone experienced this issue.

1. Flight Director - Since I purchased the 690B the flight director is very sensitive. They just seem to fly off as if you are completely all over the place. What should be slightly off course look like it's all over the place. It's not really a big deal but when in IMC with turbulence you are concentrating on the screen. It's creates a sense of motion sickness. Even with very little turbulence it will show all over the place. I have been shifting back and forth and keeping an eye on the stand by artificial horizon.

I don't know anything about avionics but I think it should be simple to adjust the sensitivity. Anyone experienced this. I don't know enough to even know if this is an auto pilot issue or display issue.

2. Bank Angle - When the autopilot (2100) is engaged and with GPSS Nav when I hit a way point and there is a turn it will bank into a 30 degree bank. Not an issue 95% of the times but in IMC conditions it seems excessive. I would think this should be a fairly simple adjustment.

Thanks for any input someone can share.

Hi Sean (Is that right),

Who is your instructor at SimCom?

I am an 840 owner.

I know you can keep the Meggit engine display, because I know someone who used to own a 1000 which had G600s and the engine display. He also took the rest of the Meggit stuff out.

Bruce - Yes that would be great. All the technicalities I won't know. Just curious to know how that process works on an annual.

I removed mine just to have less hydraulic actuators and linkage, but I think if I had a faster -10 I would just keep them, like Steve has done. Not sure the removal is worth it.

Can you keep Meggit engine display if you change the rest? Are they standalone and not interconnected?

If you’d like some light reading material, I think I have a maintenance manual digital form I can send you Andrew.

Most of the time when I mess with the interconnect, I find I end up making the situation worse, rather than better.

 ;D. Me too. 

It could be useful if you’re on an incline and want to top it off from the high wing.

Are you getting rid of the Magic engine display?

I went the other way.  My airplane did not have gear doors on it when I bought it. I had the doors reinstalled on my airplane.  I flew it for two years without the doors.

It just looked like the lack of doors had to cause drag and turbulence.  The wheels sit pretty deeply into the wheel well leaving an obvious source of drag and potential cracking on the wheel well cowl.

I know on 421’s by adding hub caps you can get improved climb and cruise performance.  It seemed adding the gear doors back would help the commander.

The only down side was possible MX cost.  So far no issues with the doors.

I had tracked performance before and after.  The doors added 300fpm in climb and 5kts in cruise.  They also lessened the vibration noticeably.  On the first flight I could feel the reduced vibration through the floor.  It was like when I upgraded my props on my 421. 

I also like having the plane as close to factory condition as is possible.  Was it worth it?  It was for me but  probably not for everybody..  The cost was $20k, but I also like the way they look.

I would not remove them if I had them but 20k is a lot for the improvement gains.
