Hi there,
I can’t figure out how to use MACH instead of IAS for the autothrottle. It has a button saying ‘PUSH IAS - MACH’ on the SPD dial but nothing changes. Am I doing something wrong?
The mach/ias knob has a base portion you can turn and the outer portion you can click and turn. Switch to manual mode by clicking the base portion of the knob and you’ll be able to switch between the two on the outer knob.
