What is JAR 25 aircraft?

What does this mean? Thanks!

It relates to the various safety standards which are used worldwide to certify aeroplanes.

The (slightly simplified) brackets are...

Part VLA - non aerobatic 2-seat aeroplanes up to 750kg MTOW, stall speed up to 45 kn.

Part 22 - gliders up to 750kg MTOW, motorgliders up to 850kg, stall speed up to 80 kph

Part 23 - aeroplanes with no more than 9 passenger seats, and an MTOW no more than 5670kg (12500 lb); or piston prop aircraft (twin engined in Europe, no limit using US regulations) with no more than 19 passenger seats and an MTOW of no more than 8618kg (19000 lb), stall speed up to 61 kn

Part 25 - anything too big or too fast to fit into any of the above categories. In general this means airliners and bigger business jets.

The difference between JAR and FAR is European versus North American regulations. In practice, they're very similar.

Much clearer now...thanks Genghis.
I asked this because Ryanair either wants 737 type-rated or JAR 25 a/c...!

I think this is true of a lot of airlines, the question crops up once or twice a year somewhere on PPrune for that or a similar reason.
