SPEED BRAKE not arming

[Artman]

The SPEED BRAKE is not arming when the handle is set to the ARM position

Try to assign a button to "extend speedbrake one notch" and then try again - even in the real 737 the positioning of the lever is "finicky" and it is easy to misplace it and either not arm the speedbrake or actually start extending it.

And of course you are not trying to arm the speedbrake while on the ground, are you?

Thank you, I'm trying exactly this way
I assigned the button to "Speedbrakes toggle between arm/disarm". But it was to no avail.

This screenshot was taken on the ground as an example. But the problem also manifested itself in flight.
We'll try the recommended one on our next flight.

In flight it should work! Let me know if it does not for you, we will troubleshoot together then.
