Not too sure what type of familiarization the ATC folks get on the performance characteristics of the aircraft types, but I agree jumpseat rides might be beneficial under the right circumstances..my recent departure from AUH in a light 767 in trail of a rather full A320 was interesting as well, cleared to 13,000' as normal, then every 45 seconds or so cleared another 2000' higher...this all the way to fl360...a vector for climb was apparently not an option, if the ATC fellow had more familiarity with the performance issues between the two aircraft, then maybe this could have been anticipated/avoided...or very specific, published profile departure procedures to be followed by us, so we can anticipate...either way, suprised parties on either end of the microphone, can lead to headaches for all concerned.....
