Default Dual start buttons

Maybe this is an odd question, but I was wondering if it is possible to install two independent start buttons: one for the left seat and one for the right seat. There is no legal reason that you can't fly from the right seat. Correct? And with dual G3X screens, it seems that you could have all the information to fly from either seat.

The reason that I ask is that my wife is getting her license and is 5'2", while I am 5'8". She will have to have foot pedal extension and a custom seat. It would be much easier to set one side up for her and one side for me and not to have to switch things if she wanted to fly on her own.

Once the plane is started, the mag check can be done from the right seat even if they are on the left side.

Is this a crazy idea?

Thanks
Ken

Not quite sure if she can reach the mag switch, why can't she reach the starter?
My Wife flew our RV-6 from the right seat. We had the mag switches and starter on the throttle/mixture/etc. sub panel.
No reason you can't have 2 starter switches. I just don't see the need.

wouldn't it be hard to control throttle while starting and reaching over to hit the start button?

I guess the other option is to have start switch on the stick.

You would want to put the mag switch(Es) close to the middle of he Panel and could easily out in two independent start switches/buttons, but you would probably want a starter enable switch so you could disable the right button at least if there is a kid riding over there that may like to push buttons. You donít want to crank the starter in flight.

As for dual key switches, I canít think of a way that would work unless maybe you used relays. With either switch on off the mags would be dead. You would have to set it up so the mags are on the NC pole of the relays and either mag switch on would energize the relays to turn the mag or mags on. I wonít speak to the safety of using relays to run the p-leads.

I will have Vertical power, which will disable starter switch over 600 rpm. I will be using push button start with a hidden switch to "lock out" the ability to start. I agree that Mag switches near the middle would be good.

This is a thought experiment at this point.

Default Middle

Put the switches in the middle of the panel. Or closer to whoever canít reach them.

This was my thought as well. Why not in the middle, right above the throttle?

Otherwise, if the mag switches can stay on one side, the starter could as well. If you can reach one, you can reach the other...

I tried to avoid putting flight-critical switches too near the throttle/mixture. Probably overthinking it, but didn't want to risk tripping one when reaching for a control. No doubt guarded switches, or careful placement, would solve that issue.

I don't use a mag switch. I use two toggle switches and a button for starting.
Vendors also have mag switches without the starter portion. You can wire two buttons so that either one can be used to start the engine. The mag switch with the button is wired by the manufacturer so that when starting it shorts out the mag without the impulse coupling so that the engine will not start before top dead center. I have one electronic ignition and a mag without impulse so I start with the electronic ignition and then turn on the mag after the engine starts. The buttons can be placed so that both pilot and copilot can have a hand on the throttle when pushing a button.

My RV-9A has the ignition switch on the far left, and it's very reachable from the far seat. Yes, you have to lean across, but so what? As for hidden switches and such, hard for me to see that the upside outweighs what I think is a considerable downside.
