I am consulting for an OEM who needs an EFIS for their production aircraft, the ArrowCopter (www.arrow-copter.com). The EFIS will be a Dynon SV 1000. But the question remaining is whether the SV setup can be somehow "locked" against changes in the screen layout. This feauture is required by the certification authorities who want to make sure that a user can't accidentally get rid of certain instruments available only on the EFIS display. We have been using MGL Voyager units so far, and they did support a 3 level locking scheme.
