What does the AE prefix do to a piston engine?
G'day
As far as engine prefixes go i'm aware of what they all mean (eg: I = fuel injected, O = horizontally opposed etc...) except for these two: A and E.
eg: IO-360-A1B6 vs. AEIO-360-A1B6
'A' for Aerobatics so what are the actual differences between an 'A' engine and a 'non A' engine.
eg: in the above example:
- I presume the engine produces the same BHP and has the same temperature and RPM operating limitations, same compression ratio etc....?
- Is the major difference the 'A' engine has a dry sump oil system and a fuel delivery system which allows for unusual attitudes and inverted flight etc...?
And as for the E I have no idea except that in my experience where there's an A there's usually an E that follows. So what is the 'E'?
Thanks in advance

There is some basic info at
http://www.lycoming.textron.com/main...ticEngine.html
More detailed info from the Type Certificate Data Sheet, eg # 1E12 at
http://www.airweb.faa.gov/Regulatory...e?OpenFrameSet
Some useful info here:

Of course, there is what happens when you fit the Christen system to an ordinary engine (Experimental unless per one of the few STC's):

The Lycoming inverted oil system fitted to the AE series is basically the Christen system' however there are additional mods to the AE's.
Finally, another Experimental option is the Maxi-Sump
