I am working on a research project for shock control in transonic flight. Currently I am trying to come up with some data about typical flight conditions during long range missions, where wave drag may occur. Important information for me would be how lift coefficient, mach-number, altitude, etc. change during a flight. I figure these information are some way or the other available from flight plans, however, I can't find any source to get a representative number of flight plans from.
Is there anyone out there to give me any tips on how to find these kind of data? Or are there any long range pilots that can give me some estimates at least on typical changes in cL and mach-number during a mission (preferably for A340 but any other type is welcome as well)?
Thanks for the help,
