Tests after avionics and autopilot re-fit

[rmac]

My Cessna 303 is about to finish a major re-fit where a new S-Tec 55X, an Aspen PFD1000 and an Avidyne 500 with integrated hazard suite have been fitted. Two GNS430W already exist in the stack.

I will have to flight test the equipment. I have 800hr multi/IR and know the aircraft very well. A multi thousand hour ATP friend has agreed to fly with me on the tests as a second pair of hands, but very limited knowledge of the aircraft.

Any advice as to a process to follow, what order to tackle the tasks in, what needs to be covered etc, will be most welcome.

Thanks
