I have decided to finish my last few instrument 141 lessons, the EOC and Checkride in our glass complex aircraft. The short story reason is below. So we have run into an odd problem. We can not figure out how to do partial panel approaches. Our complex aircraft have Avidyne EX5000 with STBY AS, AI, and ALT. You can fail the PFD/AHRS but that leaves you w/o a Turn Coordinator or VSI. Which means you can only shoot a GPS approach partial panel. You also can not do any partial panel constant rate climbs/descents. So we are trying to figure out how the DE is going to do the partial panel testing. Long story short I have not flown our main instrument plane, steam gauge, since DEC because my old CFI had to leave, both our DEs left on medical leave and winter break. So I went ahead and finished the cross countries for commercial which involved our complex aircraft. So now I have my most recent 20+ hours in our Pipers. So my current CFI and me decided it would be quicker and easier just to finish off my instrument in the Piper or so we thought.
