Hi ALROT....!
Do what I do if you want to chat now and again, and you are on a long flight....
I set my heading on the Heading bug, and my altitude on my Bendix-King radios, switch on the Auto-Pilot, and the plane will then fly by itself while you type in the Chat Window...

...!
It's what I do in my Beech Baron during Jimbo's Tours...

...!
Try it first in a small
General Aviation aeroplane, fitted with simple radios containing an Auto-Pilot rather than a large, complex passenger jet....

...!
A
default Cessna 172/182 will be ideal.
REMEMBER!....only use
DEFAULT AIRCRAFT!....non-default ones will not appear to other fliers during the flight...trust me...

...!
Cheers ALROT...looking forward to flying with you...

...!
Paul....G-BPLF....
