Hardly a month goes by without Flyer! Magazine (only one I subscribe to) trumpeting the arrival of a new diesel fitted aeroplane.
I know !
Seen this months edition ?
A flight review of the DA-40 (again). *Sigh*
I don't think that there will be immediate cut backs on hourly rates - (EDIT) €40,000 was the last price tag I seen for a diesel for a C172. (From flyer magazine) Engine only at €19,500
There was a review a while back (within this year) about a C172 converted to diesel.
The performance of the engine isn't as good in the "spamcans" as on the lighter composite Diamond Stars.
