Actually, not bad kit in my single.
Flymap 7 moving map with current charts (including the heliroute charts)
Virtual horizon with electronic AH altitude and height over ground displayed
Radio altimeter (in addition to the 2 altimeters)
Mode S transponder
2x radios
VOR navigation
Second Garmin GPS with the usual ATZ information
And all the usual flight instruments.
I don't have 2 engine, autopilot or stability control but I do know precisely where I am, at what height and my clearance over ground. Mode S means that ATC know also so I don't break any rules (never did even without all that kit).
