It presents the main differences compared to the atmosphere model currently implemented and provides information on impact of introducing the changes in the BADA family 3 model algorithms. Benefits in terms of improved aircraft performance parameters accuracy and ensured consistency between the atmosphere models used by aircraft performance models and aircraft Flight Management System are also identified.
The new BADA atmosphere model has been used in the identification process of the BADA revision 3.7 and it will be used in all subsequent revisions of BADA family 3. The aircraft performance coefficients of the BADA 3.7 and onwards are compatible and may be used with both atmosphere models. Although the implementation decision is left to the users of the BADA family 3 users, the implementation of the new model is highly recommended by the BADA project team at EUROCONTROL.
