If one uses other a/c manufacturers (I do wish Flight Mag would stop calling them airframers

) there is a common product progression.
You know where this is going already - singles then twins. Tecnam, Diamond
DynAero and I' sure others have all followed this route with varying success.
Has Cirrus spotted the fact that some customers leave their orbit to step up to a twin and that to hold onto them they need the right equipment? After all it's easier to retain repeat business than to spend money attracting new buyers.
Single engined turbines are OK but the market is smaller than for twins engined a/c. Doesn't the PiperJet failure support that?
