Well when the CAA first issued the Engineers guidance document for licencing and gave 2 examples for getting a
Cessna Twin Engined Pressurised Metal Piston Engine Aircraft Group Rating.
And the two examples given in the CAA book of words were the
Cessna 500 ( Citation Jet )
and the
Cessna 441 ( Conquest 2 TurboProp )
I knew nothing would suprise me, so a Cirrus twin is about right.
