Longitude Mach Speed switch

Hello,
When i click on the speed knob on the autopilot to select Mach number, nothing happen.
It alway stay in knots.
I tried to bind a key to switch from mach to knots, it works, but just for 1 or to 2 sec.
It always reverts back to knots.
So i’m unable during climb for example, passing fl300, to switch from knots to mach.

Any idea?

Ps: for info, i use the WT Garmin, and the longitude mod

Best regards

@Superbibi56 Have you selected the little knob behind the speed knob from FMS to MAN. The speed knob works for me by pressing the centre of the knob.

Thanks for the reply.

I just found the solution :slight_smile:

Actually, I had all help buble deactivated.
So, I turned it back on and and the help told me to hold left mouse click the speed knob and right mouse click to switch from mach to knots.

Didn’t know this trick :smiley:

Hope this might help others :slight_smile:
