Abstract

Methods and apparatus are provided for automated flight preparation. Methods and apparatus may be used to automatically determine gross weight, weight and balance, take-off distance, rate-of-climb, and flight dynamics, such as fuel, time and distance for an aircraft. In addition, information such as airspeed system calibration, and power-off stall speed in angle of bank may be calculated.

determining automatically a gross weight for the aircraft;

receiving a set of data indicating a rate-of-climb for the aircraft;

receiving information indicating conditions affecting the rate-of-climb for the aircraft;

determining automatically a rate-of-climb for the aircraft based on the gross weight, conditions affecting the rate-of-climb, and the set of data indicating the rate-of-climb; and

providing the rate-of-climb for the aircraft.

2. The method of claim 1, wherein receiving information indicating conditions affecting the rate-of-climb for the aircraft comprises receiving a measurement of outside air temperature.

3. The method of claim 1, wherein receiving information indicating conditions affecting the rate-of-climb for the aircraft comprises receiving information indicating an air pressure.

4. The method of claim 1, wherein determining a rate-of-climb for the aircraft comprises determining a best rate-of-climb.

7. The method of claim 5, wherein receiving information indicating conditions affecting the flight dynamics of the aircraft comprises receiving information indicating an air pressure.

8. The method of claim 5, wherein receiving at least one set of flight dynamics data comprises:

receiving a first set of flight dynamics data at a first weight;

receiving a second set of flight dynamics data at a second weight; and

calculating a third set of flight dynamics data based on interpolating between the first and second set of flight dynamics data.

9. The method of claim 5, wherein determining automatically at least one flight dynamics parameter comprises determining at least one of time, fuel, and distance to change altitude.
