Re: Light-Sport Aircraft Yahoo group Can anyone read German

Average recip SFC ~ .45
Previous mentioned Turbine SFC~1.00 (over twice the fuel consumption of
recip)
Rotary I understand the SFC's are a little over .55 for them...
The turbine would lose it's advantage (IE weight) from the need to carry much
more fuel. Also as far as this group is concerned is a moot point anyway since
they are not allowed in SP aircraft.
So like it or not your down to recip or rotary and the recip still has a fuel
efficiency advantage.
Also electric is not allowable under current SP rules....
