Can't activate ATS

[vdrummer4]

Just wanted to fly the Challenger after some time and after engine start, I can't get the ATS to work (neither the small green light nor the ATS screen is lighting up). I've followed the check lists for cockpit preparation and engine start.

Any idea what I could be missing?

Double check the thrust limit page.

TO was set if that's what you meant. Anything else to look for?

If you followed the checklists there shouldn't be any problems. If you send a screenshot maybe we can figure out what's going on.

I set up the plane as I usually would and made a short video showing the cockpit state at the point ATS is mentioned in the after start checklist.

After pressing the front button on the throttles as you just did, to clear the FAIL message, Press the TOGA button, not the ATS button.

So pressing the buttons at the front of the throttles to clear the FAIL message and then pressing the TOGA button on the throttles? That didn't work for me...

The ATS button isn’t the “I want to get a thrust rating armed” button, it’s the “I want to engage auto thrust and fly right now” button, kind of like the TO/GA button on a Boeing.

Please make another video? To be safe, do not use the default TOGA command binding, use the custom ones, if you’re using a keyboard or joystick button.

Can you please use non-persistent mode to test the procedure? Just to eliminate an airframe issue. A video starting from before you got into FAIL would also help.

[vdrummer4]

Sure, I'll check my key binding for the TOGA, try in non-persistent mode and make another video if the behavior still shows then.

Thanks for your help so far, everyone!

Update: The ATS works just fine with non-persistent mode. The ATS FAIL is there as soon as I turn on the APU GENs.

I will just use a new airframe for tonight. I have the old one saved in case someone wants to debug further, but as long as the new one works, the issues is resolved for me. Thanks again for your help.
