V-Prep: Airbus A320 Flying Efficiently


A320 Flying Efficiently The flight crew should be commercially and environmentally aware, and attempt to operate the aircraft in the most efficient manner Even small changes in the way the aircraft is operated can make a considerable difference to the profitability of an airline and reduce the damage to the environment Global aviation contributes around 2% of global carbon dioxide emissions and 12% of the total carbon dioxide from transportation When burned in the atmosphere 1 tonne of jet A1 fuel will combine with oxygen to create 3.15 tonnes of CO2 plus many additional toxic compounds External Condition of Airframe The airframe has a direct impact on the aircraft’s efficiency and performance Minor dents, misaligned panels and flight controls, worn seals, Operating Techniques to Reduce Fuel Consumption Use of APU The APU burns approximately 130 kg per hour If operational conditions permit consider delaying the start of the APU until 5 minutes before engine start Start and Taxi Delay engine start for as long as possible Use minimal power to start the aircraft moving. Once moving, generally only idle power will be necessary to maintain taxi speeds Carbon Brake Wear Reducing break wear not only saves on engineering costs for your airline but also reduces the environmental impact of the energy required in manufacturing The cost of a carbon brake stack can be up to $200,000 It is the number of brake applications, even at low speeds, that is the primary factor affecting brake wear Taxi In Delay selection of the brake fans for AT LEAST 5 minutes, or until at the gate. This allows the breaks to stabilise in temperature across the discs. By flying more efficiently, we can all help lower our carbon emissions, and reduce costs
