[Curt: this deserves a link on the FlightGear site.] [Jon: ditto for the JSBSim site.]
I think that this could be a treasure trove of aero data from the European Organization for the Safety of Air Navigation. Here's the abstract from the BADA manual for version 2.6: The Base of Aircraft Data (BADA) provides a set of ASCII files containing performance and operating procedure coefficients for 166 different aircraft types. The coefficients include those used to calculate thrust, drag and fuel flow and those used to specify nominal cruise, climb and descent speeds. User Manual for Revision 2.6 of BADA provides definitions of each of the coefficients and then explains the file formats. Instructions for remotely accessing the files via Internet are also given. These seem to be designed for ATC use, hence the limited selection of aero coefficients, but still, it's something. Here's the link to the complete version of the 2.6 manual: http://www.eurocontrol.fr/public/reports/eecnotes/1997/not23-97.pdf And here's the location of the actual data files (current version seems to be 3.3): ftp://bada.eurocontrol.fr/bada/ For each aircraft, there are three files: 1. The Airline Procedures File (*.APF). 2. The Aircraft Performance Operational Files (*.OPF). 3. The Performance File (*.PTF). As an example, here are the files for the Dash-8: ftp://bada.eurocontrol.fr/bada/3.3/DH8C__.APF ftp://bada.eurocontrol.fr/bada/3.3/DH8C__.OPF ftp://bada.eurocontrol.fr/bada/3.3/DH8C__.PTF Unfortunately, the DC-3 doesn't seem to be included. With 166 different models, you'd think they might have slipped it in...
