And another one, and this one is a daily if not hourly one here. I have an aircraft on a heading, and I have issued a requirement to maintain a climb rate of 1,500 ft a minute or greater until through FL240 due crossing. Another converging aircraft departs and so I need to change the heading of the aircraft with the climb requirement. I have now recleared this aircraft and you're telling me I need to restate the climb rate requirement or he will resume own rate of climb????? Say it aint so!
