i'm working on learning the Tomcat and following along in Chuck's guide. However I can't get the autopilot to work. Here's what it says:

ALTITUDE HOLD: Barometric Altitude Hold. When engaged, aircraft will maintain current heading and barometric altitude. a) Ensure aircraft vertical velocity is approximately within +/- 200 ft/min or the autopilot cannot be engaged. Try to fly level and aim for a vertical velocity of 0 ft/min. b) Ensure Yaw, Pitch & Roll SAS switches are ON (FWD) c) Set Autopilot Switch to ENGAGE (FWD) d) Set Autopilot Altitude Hold Mode switch to ALT (FWD) e) Wait for the A/P REF warning light on the left side of the Vertical Display Indicator (VDI) to illuminate f) Press the Autopilot Reference/Nosewheel Steering button on the control stick to set the current altitude as the reference altitude.

However it will usually just begin to dive shortly after. Anyone know if this guide is correct?

I think there are some issue regarding the autopilot and FFB. Not sure if that got fixed. 

Cheers! 

I knew there were some issues with the AP last year however i thought I saw in an update they fixed it. hmmm

Yeah, I'm not sure if it was fixed. They have aquired an FFB stick though, IIRC.

that's good! i use a ffb stick too so maybe they can help get it working.

How fast are you going? and at what altitude?

i was at 35,000' @ mach 0.9ish

Mach .9 is on the edge of where the autopilot is going to lose effectiveness because of transsonic shenanigans. I'll check if it's expected to be able to hold, but you might be going too fast.

Checking the NATOPs, See if the problem persists if you're not at M0.9

thanks for the info. i believe i tried it at other altitudes and speeds but the behavior seemed to be the same. but i'll try again
