Abstract

A method and system for determining and implementing weight distribution of payload on an aircraft for optimizing centre of gravity of the aircraft by providing an individual weight factor for each passenger and/or crew member and their respective hand luggage and allocating at least a portion of the passengers and/or crew members seats according to the effect of passenger and/or crew member'"'"'s positions on the aircraft on centre of gravity position provides advantages in determining accurately cabin payload data and cabin payload distribution for optimum fuel efficiency of an aircraft on a flight. Thus, fuel may be saved and car bon dioxide emissions may be reduced.

Claims

1. A method for determining and/or implementing weight distribution of payload on an aircraft for optimizing centre of gravity of the aircraft, which method comprises providing an individual weight factor for each passenger and/or crew member and their respective hand luggage and allocating at least a portion of the passengers and/or crew members seats according to the effect of passenger and/or crew member'"'"'s positions on the aircraft on centre of gravity position.

2. A method as claimed in claim 1, which method further comprises providing an individual weight factor for any or each item of cabin payload including individual weight factors for passengers, crew and their hand luggage (together or separate from said passengers and crew), on-board catering equipment including catering trolleys and other moveables and identifying and/or allocating a location for any or each of said items of cabin payload in assisting with the optimal distribution of cabin payload on an aircraft.

3. A method as claimed in claim 1, wherein the centre of gravity of the aircraft is optimized for fuel efficiency.

4. A method as claimed in claim 3, wherein optimization for fuel efficiency is taken to mean within the legal requirements for safe operation of the plane for the entire flight.

5. A method as claimed in claim 1, which comprises the steps of:

A) identifying the optimum centre of gravity of the flight for fuel efficiency for a particular aircraft;

B) identifying the nominal optimum starting centre of gravity for the aircraft for a particular flight from a first departure point to a second destination point;

C) providing cargo and hold baggage weight and distributing optimally according to the nominal optimum starting centre of gravity;

D) providing total weight of cabin payload;

E) calculating a qualified actual fuel load for the trip;

F) providing weight data on cabin payload in the form of individual weight data for passengers, crew members and their respective hand luggage;

G) providing qualified actual optimum starting centre of gravity for the aircraft for the particular flight with the particular load; and

H) distributing the cabin payload to adjust the centre of gravity toward the provided qualified actual optimum starting centre of gravity; and

,

I) optionally, repeating steps E, F, G and/or H for optimisation of and iteration of the calculation of qualified actual optimum starting centre of gravity and the qualified actual fuel load for the trip.

6. A method as claimed in claim 5, wherein individual weight data for passengers, crew members and their respective hand luggage is declared and/or actual data.

7. A system for determining and/or implementing distribution of payload on an aircraft for optimizing centre of gravity of the aircraft, the system comprising a means for providing an individual weight factor for each passenger and crew member and their respective hand luggage and a programmed computer arranged to allocate passengers and crew members seats according to the effect of passenger and crew members positions on the aircraft on (e.g. longitudinal) centre of gravity position (relative to, preferably, an optimized starting centre of gravity optimized for fuel efficiency).

8. A system as claimed in claim 7, which system further comprises a measn for providing an individual weight factor for any or each item of cabin payload including individual weight factors for passengers, crew and their hand luggage (together or separate from said passengers and crew), on-board catering equipment including catering trolleys and other moveables and a programmed computer configured to identify and/or allocate a location for any or each of said items of cabin payload in assisting with the optimal distribution of cabin payload on an aircraft.

9. A system as claimed in claim 7, which comprises

A) means for identifying the optimum centre of gravity of the flight for fuel efficiency for a particular aircraft (e.g. database of information relating to a range of aircraft from which data may be selected);

B) means for calculating or identifying the nominal optimum starting centre of gravity for the aircraft for a particular flight from a first departure point to a second destination point;

C) means for receiving input data relating to cargo and hold baggage weight and for allocating distribution optimally according to the nominal optimum starting centre of gravity (e.g. a computer programme product comprising a computer-readable medium incorporating program code executable by a processor to allocate cargo/hold baggage load distribution and, optionally, individual, collective or total cargo/hold baggage weight determining apparatus in electronic communication with said means);

D) means for providing total weight of cabin payload;

E) means for calculating a qualified actual fuel load for the trip;

F) means for providing weight data on cabin payload in the form of individual weight data for passengers, crew members and their respective hand luggage;

G) means for providing qualified actual optimum starting centre of gravity for the aircraft for the particular flight with the particular load; and

H) means for allocating distribution of the cabin payload to adjust the centre of gravity toward the provided qualified actual optimum starting centre of gravity.

10. A computer program product comprising a computer-readable medium incorporating program code executable by a processor to implement a method as claimed above.

11. A method for determining the fuel load required on an aircraft for a flight from a first location to a second location, the method comprising calculating fuel requirement based on actual zero fuel weight determined using actual weight of passengers, hand luggage and cabin crew and calculated fuel requirement based predicted fuel usage assuming optimum centre of gravity for the aircraft for a flight.
