Using RT to give out SID's? What a blatant misuse of airtime, thats what datalink clearance is there fore, isn't it? Makes it even easier to protocol the clearance too, simply print it.
Anyway, we all know the brits have a few special quirks, providing the aircraft type on initial call is one of them. Most of the rest of the world doesn't need it, either because their airlines actually have competent OPS departments or ATCO's that can actually cope with a Fokker 100 instead of a Fokker 70 which is the same wake turbulence category in the rest of the world anyway.
