There is no FTL regulation from JAR anymore as it is now regulated by EU-OPS Subpart Q. That piece of regulation as noted above is in many cases quite vague and requires additional local regulation. Flying duty of more than 8 hours is absolutely common both on shorthaul and longhaul flying, up to 14 hours FDP is possible without going into discretion, depending on report time that can be up to 13 hours of flying with only minimum crew, in fact that is how longhaul flying is done in "my" outfit as we do not use augmented crews at all. Shorthaul is not much different, but we often do 3 sectors instead of one which reduces max FDP to 13:30h. Since the longest sectors shorthaul are around 5 hours that works quite well if you do the usual central europe, canaries/egypt with two landings there and back to central europe (5 hour sector, 20 min sector, 5 hours sector). All done with min crew of course.
Are we fatigued? You bet, having to fight against dozing off alone while the other one sleeps for 4 hours on a shorthaul flight is very common, waking up to find the other one asleep as well, both on short- and longhaul flights.
