1. Pilots can vary flight level, wind, temperature, weight, and sector cruise distance to find the optimum indicated airspeed and/or mach number.
2. The first displays the difference in total costs, fuel burn and time, for each flight level when compared to the selected flight level (all other variables the same).
3. Cruise flight conditions are input by the pilot, then complex algorithms calculate an exact cruise speed which will result in the minimum possible cost for a flight.
4. The flight level with optimum total cost, which is usually the highest achievable level, is highlighted in black with green text.
5. Time difference between optimum cruise speed and minimum time speed can be displayed.
6. The number of days since the last update is displayed on the "Downloads" tab badge and also the app icon badge to remind pilots to update the data whilst on the ground.
7. The second feature displays the wind required at each level to break even with total cost when compared to the selected level.
8. "Level Change" provides unique functionality to aid crew when deciding whether to climb or descend for operational reasons such as turbulence or strong headwinds.
9. For sector lengths approaching the maximum operating range of the aircraft type, a speed for minimum fuel burn is calculated.
10. Calculations are performed using a tailored aircraft specific data model and customer specific operational costs.
11. There are over 150 parameters that can be displayed on either of these pages, which can be constructed so that crew do not see any sensitive operational data.
