Hi. New the J41, just picked it up last week and loving it.Yesterday I encountered what I think was my first "emergency". Shortly after takeoff, I set the HDG ON in the AP to follow a departure procedure as requested by Vatsim ATC - standard stuff and it worked fine. Once cleared, I engaged the NAV and set the FMC to my next waypoint and everything seemed fine. I had the Yaw Dampner and the AP both ON and green, along with the NAV on, and the ALT SEL + VS to get to my cruise altitude. About 1 minute into the climb, i heard a quick beep and ALL the lights on the AP went ON - with a yellow amber light and the solid green light. All settings: NAV, HDG, IAS, VS, etc... they were all on. There was no alert at the time other then icing detected which was quickly dealt with using the ice boots and heating.Any ideas? I could not figure out what happened or how to reset it. On reaching my destination my APPR would not work and would never engage the localizer.thanks

Sounds like hardware interfering with the trim, which kicked off the autopilot. Check to make sure you don't have any hardware trim axes set (or that the hardware trim is zeroed before engaging the AP).

I helped trouble shoot it with him over on the FSE Forums and it ended up being the SBY button being pressed and left on. Was able to find it in the manual. So its a feature not an error or bug.

No idea what your problem is, but you should be using IAS to climb, not VS. VS gives no speed protection so if you slow for any reason, it will simply pitch up further and further to maintian the rate of climb. If you were distracted by what ever it was that caused you to slow, you will quickly find yourself in dangerous territory.
