Kliment, L. and Rokhsaz, K., "Comparative Usage of Two Similar Airframes," SAE Int. J. Aerosp. 8(1):174-181, 2015, doi:10.4271/2015-01-9006.
In-service data from two Bombardier business jets, a Global 5000 and a Global Express XRS, have been compared. Flight data has been analyzed from both airframes with comparable number of ground-air-ground cycles. Individual flight phase have been examined and compared between the two airframes. Primary emphasis has been placed on airframe usage. The influence of primary mission on ground-air-ground cycles has been highlighted in the form of ground and flight loads, as well as dynamics of the flights. It is demonstrated that safe-life maintenance approach may have to be adjusted to account for the airframe usage.
