1,338 TT when I lost my medical :-(
PP-ASMEL,Inst (single only),
I applied for a waiver, declined. If only I had simply not renewed,
I'd be eligible for Sport Pilot today. A pisser.
MOST pilots cannot operate a GTSIO Continental or TGIO Lyc properly.
It's a job for a FLIGHT ENGINEER, not a PILOT. Single pilot IFR in our
nightmarishly complex ATC system is tough enough in a
single-power-lever aircraft.
One mag, one electronic system with an electronically trimmed
mechanical FI system-called "supervisory" rather than "full
authority"-would give 99% of the redundancy of two mags plus provide
for single lever power control (especially if we got rid of free air
cooling, which worked on the A-65 in the J-3 pretty well but which has
no place on a 240 kt aircraft).
The average GA pilot IS NOT Yeager, Armstrong, or Hoover. And will
not, cannot, and does not want to be. Personal aircraft are consumer
products. We need to get rid of the fighter pilot mentality and design
for realistic owner-operation. That means single lever power control,
positive redundant electrical and/or vacuum sources for full panel (no
needle ball and alcohol crap-even the Air Force does not expect UPT
pupils to fly the T-38 that way) attitude display, and a few other
things. Combined with mandatory basic aerobatic training and airframes
that make even minimal use of crashworthiness lessons learned in
military helos and race cars, aviation can be made safe.
Of course you don't want that.

Dragsters have no electrics, and besides on fuel cars the ignition is
for start and idle. Once the run starts hitting the mag kill switch has
no effect.
Sprint cars also run mags.

P.S. Ask your A&P about the dual mags on your Continental and the ONE
gear that drives both.
