The Airbus A320:
The Airbus A320 is a 1987 passenger plane.1
The plane uses 2.91 kg of fuel per km on a medium haul flight.2 We do not know what type of fuel it uses, but typical values for aviation fuel are around 44MJ/kg.3 Thus to fly a kilometer, the plane needs 2.91kg of fuel, which is 2.91 x 44 MJ = 128MJ of fuel. This gives us 0.0078 m/kJ
According to modernairliners.com, the A320’s ‘operating empty weight’ is 42,600 kg and its ‘maximum take-off weight’ is 78,000 kg.4 We use the range 42,600—78,000 kg, since we do not know at what weight in that range the relevant speeds were measured.
This gives us a range of 0.33 – 0.61 kg.m/J
