How necessary is the SV Knob panel for use with the HDX? I am upgrading from a classic to the HDX and am thinking of removing my knob panel for additional panel space. This panel is great for the classic but is it really necessary with a touch display?
You've gotten a bunch of responses indicating great support for the knob panel. And if you have enough panel space for it and all the other stuff you want/need, I agree - it's very useful and helpful. But on my COZY MKIV panel, I would have had to lose either the COM head or the A/P controller head, and obviously that couldn't happen while still retaining those functionalities. So the knob panel was not installed.
While I agree that it's a bit more of a PITA to set the heading/track, altimeter and altitude via the touchscreen and/or EFIS knob, I don't find it a large problem - having to touch the screen before twiddling a knob takes all of an extra second or two, even in turbulence. There's nothing else on my panel that I'd be willing to give up in order to get the Knob Panel. If you have the space, by all means, keep it. If you don't, it's not the end of the world to eliminate it.
