Performance at Gross Weight Site Map Email the Designer Copyright © 2012 Apollo Canard The performance data/charts above are ESTIMATES based on Airplane PDQ analysis reports.  Performance was estimated by reverse engineering another canard aircraft with Airplane PDQ software and then correlating PDQ’s predictions with actual performance, then using that same methodology for predicting the Apollo’s performance. To review the methodology used and the correlation between performance predicted by this software and actual flight test data, select the Software Tools menu and visit the Airplane PDQ page.
