As I understood it the eurocontrol classification is for enroute planning purposes and would then use distance. How would that be relevent to a tower contoller in Germany and a departing aircraft which should use time?
Means that the allowance part was used; 40 seconds + 5 seconds for you to react and grabbing the microphone + 10 seconds for radio call and lights + 25 seconds for your own line-up + 40 seconds for your own take-off run that equals 2 minutes, the bare minimum. If you move slowly into position and delay by 10 seconds or 15, you will get even more separation...
Nightrider, it doesn't take 40 seconds for a 9T jet to rotate and no allowences were applied. We were lined up fully ready when the TO clearence was given. 40 seconds had elapsed since the 738 had rotated.
OK
4 seconds to reply, "Cleared take off xxxxxxx'
2 seconds to say 'checks complete'
15-25 seconds to rotation.
Yes, because UK is different to ICAO when categorising for Wake Turbulence. Under ICAO categories your MTOW of 9T is classed as a Medium for Wake Turbulence.
In what phase of flight?
Is it 2 minutes in Germany as it would be in the UK or not? Is it wise for a 9T aircraft to be taking off to close to a 79T aircraft? I don't think so.....
