hi vfe,
you would be better sitting in the left seat unless you have dual instruments as parallax would be a problem from the right...and anyway if you've ever tried to teach instruments from the right hand side you know how difficult it is if you're doing the flying..it is difficult and can be confusing and due to parallax not likely to be as accurate (whan you think you are on the ILS from the side if may look like the needle is in the middle and it may not be..)
also the scan is more difficult from the right.....
i would'nt do it..and agree with portsharbourflyer...its no big deal switching back to the left hand seat...
