Changes in the Cruise Climb Performance of the Il-96-300 Aircraft

Abstract

The paper describes the research of changes in the cruise climb performance of the Il-96-300 aircraft performed while compiling materials of 2005–2015 obtained during the main flight performance assessment in the airplane example certification. The most important result of the work is the conclusion that not only the performances themselves but also the current limitations of the maximum cruise altitudes require revision, taking into account the altitude-speed performances of PS-90 engines that have changed, due to a number of modifications.
