250kt speed limit on departure. If you are unable, just inform ATC what speed you need. No big deal.
It's a potential hazard, can put the aircraft into an inadvertent low energy state and creates a additional workload during a critical phase flight. The procedure should be revised
With apologies Altiplano...you will have to elaborate a bit more on that...I'm with Cossack....never heard of it being a problem..and both of us work either side of the procedure. I don't understand what you mean by "potential hazard". I may be ignorant...but I don't understand why a climb to 3000ft is a potential hazard?
Both aircraft are given 3000ft, terminal chooses which one to climb higher and then does an airborne crossover. It is a pretty simple procedure, and one that on the whole works well between Terminal and Tower. It is not unknown for terminal to call the tower and tell them to clear the non conformer to a higher altitude anyway...just requires a bit of preplanning. You don't often level at 3000ft ....if you call us promptly enough we will keep you climbing, because we don't want you level at that altitude either.
The procedure is not inefficient. How can it be when you are being allowed to depart from a runway that is not the standard for you direction of flight? You are cutting back across an active departure runway...with flights that might be crossing tracks from you OR going the same way. Either way we need something to work with , and the current procedure is deemed to be the best we have at present.
You are critiquing a procedure without taking into account that ATC is working around you (non standard departure runway) and that in a parallel/dual departure environment we have to keep a pretty tight rein on aircraft within close proximity to the field.
You say you wouldn't complain if kept out straight to 5000ft...believe me Terminal would. Unless you can suggest a way to not impact the departures off the other runway...I don't see the procedure changing anytime soon.
I suggest to call departure ASAP and we will get you climbing ASAP.
