boeingdriverx not quite sure what you mean.
Are you wanting that information while flying(ie what the other traffic is) to see whether it is a genuine requirement or if its worth meeting the requirement? or are you refering to the 90% and how I arrived at that figure?
If its the first I can only speak for myself in that everytime I give a requirement for seperation I give the requirement as well as the traffic you are being seperated from. I make sure the requirement can be realistically met and if not then use another form of seperation. Others just give you the requirement and expect you to comply and if you cant then do the same and find another way. ATC don't give seperation requirements just for fun, we give it due to traffic so that seperation is maintained and we can all go home at the end of the day.
If its the second point, on my last shift 13 requirements were issued for seperation from other a/c and 11 times the pilots failed to comply and failed to advise me. Even when asked multiple times to confirm that they would make it they they replied that they would make it with ease etc etc then failed miserably to meet it. They consisted of 6xQTR 3xGFA 2xUAE cargo. This is just the failure to comply when other a/c are involved. I lose count of the ammount of times per shift that a/c fail to meet the height requirements on the STARS and the issued height requirement at DUMPI.
As always its not all pilots who do this and as with the R/T issue it is only a small portion of pilots that are unable to fly in a safe and professional manner. But when those pilots make up a large portion of your extra workload with their poor airmanship it tends to stand out. As a pilot it also must concern you that the other a/c that I am giving requirements to so they dont come near you, cant be bothered complying with them and is not only putting my job on the line but you life and the life of all on board at risk.
Hope this helps.
