I’d be very surprised if any 737 operator had an OPT that didn’t predicate the 27 take off performance data on a 90 degree line up. The tops dogs at Air Services surely meet regularly enough with the Chief Pilots to be fully aware of this kind of critical operational information though and considering that they are all part of their respective ‘leadership teams’ I’m sure they ‘cascade’ the information down to the ATC’s and line pilots. All part of a days work to keep the working boys and girls singing from the same hymn sheet. I’m sure those sorts of Leadership Tasks are completed before lunch and certainly before considering critical KPI drivers such as discretionary fuel uplift and OTP.
