ICAO Ottawa November 2002 - Morris - Weight Management

?
?
K
Kevin Morris

The document discusses various weight reduction initiatives airlines can implement to reduce fuel consumption and emissions. It describes how reducing aircraft weight by even small amounts, such as 500 kg, can significantly reduce annual fuel burn and carbon dioxide emissions. Examples of weight reduction strategies mentioned include optimizing catering and potable water loads, replacing metal cutlery and gin bottles with plastic versions, carefully monitoring weight increases from aircraft modifications, and considering removing paint from aircraft to reduce weight. The document emphasizes that weight is a major factor influencing fuel efficiency and emissions, so weight reduction should be a key priority for airlines.

Aircraft Panel Ottawa, 5-6 November 2002 22 Weight Management Weight effects on fuel and CO2 Weight reduction initiatives - a few examples Tracking weight growth and fuel efficiency Epilogue: To paint, or not to paint - that is the question
Aircraft Panel Ottawa, 5-6 November 2002 33 Conflicts Weight minimisation - easy to see the benefits BUT..... There are usually conflicts with other policies as well
Aircraft Panel Ottawa, 5-6 November 2002 44 Why look at weight? A ¡°rule of thumb¡±: additional fuel requirement: =3-4% of weight increase x hours flown ¨C e.g. extra weight = 500 kg ¨C flight time = 10 hours ¨C extra fuel burn = 150-200 kg ¨C extra CO2 = 470 - 630 kg For Every Flight!
Aircraft Panel Ottawa, 5-6 November 2002 55 Fuel cost of Weight assuming 5,000 hours/year extra fuel burn = 87 500 kg extra CO2 = 276 000 kg extra cost = $ 22 000 ? and that¡¯s just the fuel! Weight control is important
Aircraft Panel Ottawa, 5-6 November 2002 66 Catering - a lot of weight!
Aircraft Panel Ottawa, 5-6 November 2002 77 Potable Water Aircraft carry potable water in water tanks for use in flight Not all are necessarily required, but mostly always filled to capacity
Aircraft Panel Ottawa, 5-6 November 2002 88 Potable Water Blanking off 1, out of 3 potable water tanks for ¡°medium-haul¡± B777-200, prevents their use 100kg of water, per flight not loaded Annual savings estimated as 380 tonnes fuel, 1 200 tonnes CO2
Aircraft Panel Ottawa, 5-6 November 2002 99 Plastic cutlery Post 11th September 2001 Many new measures to improve security Most add weight One actually reduces weight - plastic cutlery
Aircraft Panel Ottawa, 5-6 November 2002 1010 Plastic Cutlery Using one route as an example Weight reductions (LHR-NY): ? Concorde - 34.26 kg ? B747-400 - 32.60 kg ? B777-200 - 34.40 kg Equates to: 52 t/yr fuel ($ 13k) 165 t/yr CO2
Aircraft Panel Ottawa, 5-6 November 2002 1111 Conflicts BUT THEN WHO LIKES EATING WITH PLASTIC CUTLERY?
Aircraft Panel Ottawa, 5-6 November 2002 1212 Plastic Gin Bottles Duty Free bottles of Gin Opportunity to substitute plastic bottles for glass ones Weight saving approx. 0.5 kg per bottle Average of 12 bottles carried on each Long-haul flight
Aircraft Panel Ottawa, 5-6 November 2002 1313 Plastic Gin Bottles Total annual fuel savings for Long-haul flights B747-200 = 4.7 tonnes B747-400 = 51.2 tonnes B777-200 = 39.3 tonnes Total fuel saved = 95.2 tonnes Total CO2 saved = 300.3 tonnes
Aircraft Panel Ottawa, 5-6 November 2002 1414 No Conflicts? Gin unaffected! Conclusion: Help the Environment, Buy Duty Free on board
Aircraft Panel Ottawa, 5-6 November 2002 1515 Modifications
Aircraft Panel Ottawa, 5-6 November 2002 1616 Concorde - weight goes up Additional weight due to: Fuel tank liners - 400 kg Unusable fuel - 200 kg Total extra weight: 600 kg per aircraft
Aircraft Panel Ottawa, 5-6 November 2002 1717 Concorde - weight goes down Reduction in weight due to: New cabin interior - 350 kg New tyres - 164 kg Total weight reduction: 514 kg per aircraft
Aircraft Panel Ottawa, 5-6 November 2002 1818 Concorde - weight the same? Weight change summary: Increase - 600 kg Reduction - 514 kg Overall - 86 kg increase Modifications can make a difference!
Aircraft Panel Ottawa, 5-6 November 2002 1919 Modifications
Aircraft Panel Ottawa, 5-6 November 2002 2020 Modifications Modifications usually add weight Important to ensure that mods are fully removed when no longer required! One of the reasons for unaccounted weight growth
Aircraft Panel Ottawa, 5-6 November 2002 2121 Monitoring and Control Can¡¯t control what you can¡¯t measure Modifications (mandatory & other) Unaccounted weight growth Tankering of fuel Extra fuel requirement, Emissions Extra expense, less profit!
Aircraft Panel Ottawa, 5-6 November 2002 2222 Monitoring and Control ¡°Weight Watchers¡± track aircraft weight over time monitor the actual weight of mods Fuel Efficiency Group track aircraft fuel efficiency over time Allows the use of statistical contingency fuel (worth $7M per year to BA) Saves fuel/money/Environment
Aircraft Panel Ottawa, 5-6 November 2002 2323 Paint - who needs it? Paint weighs a lot! A320-200, approx. 110 -150 kg B747-400, approx. 410 - 550 kg But it also provides a service: Protection - helps prevent corrosion Ensures a smooth surface Provides an identity
Aircraft Panel Ottawa, 5-6 November 2002 2424 So - who does need paint?
