What are the two large half dome shaped objects on the center console,
just below the keyboards, forward of the radio displays, and outboard

trying to use the keyboard, unless they're some odd kind of wrist
rest.

They're plam rests to stabilize your hand when typing on the keyboard.

Thanks. I know that it can be tough hitting the radio or transponder
buttons even in light turbulence in a small plane, but thought that a
palm rest would be shaped differently, more concave than convex.
