Narrative:

Was given the sacat 1 departure off of ffz using runway 22L; approximately 1000 ft AGL got several cas warnings; uncommanded trim; landing gear aural warning; and air data computer fail; the programmed route and navigation was unreliable also. I did not want to inadvertently fly into sky harbor's approach paths and airspace and was assessing the situation for a possible return to the airport of departure. I made a left turn back towards the airport of departure and advised the controller that I was having some issues and requested a heading. The controller gave me direct to mrbil and to climb to 5000 ft which I was able to program into the FMS and I was also able to resolve the uncommanded trim problem. I was in VFR conditions at the time of the deviation and was aware of the terrain and other traffic.
