The Maintenance Appraisal module provides analysis of the portfolio from a costing point of view.

All maintenance events on the aircraft, engines, gears and APU's are reviewed. Used life since last event is calculated as well as the expected next event dates. The used life and Half Life values are calculated based on industry average costing information per aircraft-, engine-, gear- and APU model (and intervals where applicable).

Current status, calculation results and graphs are presented on screen for review and overview reports can be printed.

Sophisticated filters can be applied for analyzing purposes such as to produce output based on a serial number, operator, aircraft model, etc..
