What does the F stand for?

I - fuel injected
O-horizontally opposed
240- cubic inches

T-turbo-charged
S-super-charged
L-liquid cooled
V-vertical installation?

Any others?

Thanks,

Paul

LIBERTY TRADES ROTAX FOR CONTINENTAL
Liberty Aerospace recently announced several changes to the XL-2, including
a switch from the design's original Rotax 912S to a 125-hp Teledyne
Continental IOF-240B. The new installation features FADEC (full-authority
digital engine control) that provides automatic mixture control and maintenance

data ports for easier servicing. "The demand for support and service was
overwhelming. We let that lead the way for our decision," said company
spokesman Skip Eavers. A gross weight increase of 175 pounds, to 1,575
pounds maximum gross weight, comes with the new engine, maintaining a
600-pound payload and 500-nm range for the two-seat airplane. The XL-2
also features a new panel layout, with a Vision Microsystems VM1000FX
digital engine information display. The base price has been increased by
$7,500 to $105,000 to reflect upgrades made to the XL-2. Liberty expects
the XL-2 to be certified in May 2002. See ( http://www.libertyaircraft.com

I presume it has something to do with the FADEC.

L is left turning.

Yes.

Must mean both - the Extra 400 has a liquid cooled Continental TSIOL-540
IIRC.

AE - Aerobatic Engine (I've also seen just "A" used for this, but I
don't know the difference between an "AIO" and an "AEIO"?)

According to Greg Travis's page, the difference (at least for Lycoming)
is whether the engine has a dry or wet sump.

Thats correct

A=Inverted, or dry sump
E=Aerobatic

"R" is obviously radial... what would an inverted (inline or V) be?
