My 2-cents worth
Yea , I can agree with most of the posts.
However nobody mentioned the great value of pilot's having flown a pressurised turbo-charged Piston twin -
i..e Cessna 340/414. 421 ; Beech 58P;
Rockwell 680FLP & the single-engined
Piper Malibu.
Ever heard of shock-cooling, fuel-vapourisation, fuel-blockages, 6-tank fuel management , 180 fpm single-engine climb , drift-down when on one overheating engine & Avgas shortages ?
Taught me a thing or 2 before going onto
JetA1 !!
