OK so what I've noticed is the following.
- 787 autopilot is screwed up. Auto throttle getting the plane to decend etc all screwed.
2 a320 I have noticed that the auto throttle decides to come on randomly especially when landing causing issues.
That said the other autopilot issues I thought I was having with the Airbus for me anyhow were from a lack of understanding how the Airbus autopilot works specifically auto throttle and managed modes.
Im an avid pmdg user and have been learning and still continue to learn how Boeing aircraft work but id like to say that as an amateur I've gotten pretty good at managing the systems. The Airbus however is Greek to me so I'm starting over.
So I hope the following helps
- After takeoff if you want to toggle the auto throttle and altitude management you have to make sure of a few things
A. You move the throttle off the toga level and into the CLB setting.
B. Clicking on the bottom of the speed knob will give you selected speed mode meaning the level you choose or click the top of the knob will give you managed speed which will use the speeds programmed in the fmc
C similar with altitude. When in managed speed mode and atc tells you decend to 15000 but in the fmc it has the way point altitude as 16000 it will stay at 16000. This is Especially true at airports like paro where there are a lot of mountains and there are minimum altitudes programmed in the fmc. To bypass this you will have to use the VS knob
D with the VS knob there are a few bugs but I have found if you toggle the VS knob on first by clicking the bottom and then use your mouse wheel to increase or decrease the VS it works like a charm.
So after that long winded msg I guess what I'm trying to say is check the position of your throttle handles. That has a lot to do with the autopilot on the Airbus. The position of the throttle will be indicated above your airspeed.
I hope this helps and if anyone has any tips on how to get the 787 autopilot working better please help.
