Round 4

Turboprop Flight Advisory System Enhancements, Testing and Engine Model Development



The objectives of this project are to enhance and extend the capabilities of an iPad-based Flight Advisory System (FAS), to perform ground and flight testing to confirm the benefits of up to 10% in fuel burn and CO2 emissions reductions in small commercial turboprop aircraft (19 or less seats) and to determine whether an engine model can be employed to define more efficient flight trajectories. Research and development activities will investigate the means to increase the utility of the FAS over a wider range of flight conditions and aircraft types, thereby delivering greater economic benefits to turboprop operators while further reducing the impact of the aircraft type on the environment.


Further developed the iPad Flight Advisory System app developed in SRS-21 with its partners Carleton University and AeroSafety. A single engine turboprop aircraft model and enhanced meteorological data were added to the app. Both single-and twin-engine aircraft models were validated with flight data thanks to the University of Sherbrooke and North Wright Airways Ltd. An engine thermodynamic model for cruise conditions was developed and implemented into the app, supporting a more generalized approach to fuel burn calculation. An aircraft dynamics model was also developed, and an analysis of engine dynamics on fuel
burn was conducted.

Up to 10% in block fuel burn savings and commensurate CO2 emissions reductions were calculated based on actual flight data.
