I’m installing a new GRT autopilot (2-axis) on my RV4. I have a Horizon 10.1 and Mini-X, installed last year. The install manual suggests either one “ENGAGE/DISENGAGE” switch for both axis’, or two switches, one for each axis (roll/ trim). From those that have done this, is there a relative advantage in having the ability to select just one axis of the autopilot? It’s not a difficult thing to do, but should I have that option, + extra switch? I’m trying to imagine when I would want one axis without the other. My vertical autopilot will have the capability of VS, IAS, or VNAV for climbs or descents.
