The GTNs have airway name entry but the on-screen keypad is not too great, and would be awfully slow to use in turbulence.
I think that's true for the GTN650, but I find the 750 keyboard screen quite easy to use in turbulence. You simply need to get in the habit of anchoring your hand on the bezel.
What are the options for this?
I think the G1000+ systems can have a keypad.
Is there anything below that?
