Hi!I recently hav had the issue that the FO won´t set the MCP accordingly on Takeoff. When I call for Heading Select, he says it, but it won´t activate. The same happens with LNAV or Command A on some occasions.Don´t know what is causing this.I reinstalled the NGX and FS2Crew, but the problem is still there.

The call is "Select Heading Select"

You sure the aircraft was configured properly?All FS2Crew does is send the signal to the NGX to engage heading select.

I am using the Button Version.I believe that the aircraft was configured properly Byork, it worked most of the time, but then sometimes not. I will check if the problem persists with SP1, which is absolutely mindblowing!

FO sometimes for me doesn't engage COMMAND A nor LNAV or VNAV, nearly crashed into a mountain tonight because I thought the FO turned on LNAV!Plane's configured properly.

The correct commands are "Select Lnav" "Select Vnav" "Select Command A"

Also remember that the control column needs to be centered before the autopilot will engage.So if you're applying pressure, the autopilot won't engage even though you ask the FO to turn it on.LNAV/VNAV... you probably weren't configured properly... the test is to try to turn LNAV/VNAV on manually.If it doesn't engage, the plane is not setup properly to accept a VNAV/LNAV engagement.Was your FMC setup properly?Best,

I only use the button control version and yes once again everything is set up properly.I follow the F/D upon take off and press the COMMAND A button and the FO says "COMMAND A", it's a hit and miss, it's either on or hasn't worked.I'll just physically do it myself from now on I don't trust it.

Hi Pete,Not sure what more to say. FS2Crew sends sends the signal via the SDK. It's pretty simple.You're 100 percent positive you're not applying any joystick pressure when you ask the FO to turn on the autopilot?

From memory, I believe that if you have PMDG option set to "Heading Select" after take off (as opposed to "Wings Leveled"), Heading select will be automatically selected shortly after take off. If so, maybe FS2Crew is "pressing" Heading select a second time, deactivating it...

As I said, this is something that occurred to me as a possibility, but I am not able to test it right now. Maybe something you could have a look.

If you arm Lnav and Vnav before runway entry, everything should work as published,
