There has been a lot of dispute on ways to predict fuel consumptions in the aviation world. Airbus and Boeing presented a unit in nm/Gal (nautical miles per gallon of fuel) to the operators but how can I relate this figure across the organization had became impossible to me. When I came across this unit I wonder, why does Airbus or Boeing did not consider weight and flying altitude since how heavy the aircraft carries and how optimized the flying altitude will have a large effect on the aircraft's fuel consumption as well. And so the unit nm/Gal is actually useless.
I am glad that I was in this position in AirAsia to make a difference in the aviation world. What I did was developed a new unit in kg/hr/kg (kg of fuel per hour of flight time per kg of weight) by tapping in existing aircraft parameters and created a unique way of measuring fuel consumption for AirAsia's flight characteristics.
Due to the reason that the finance and revenue department unable to relate nm/Gal for measuring base cost for cargo, now with kg/hr/kg, they can use this figure to tap into their revenue. The revenue people can also relate this figure to measure fuel burn contributed per passengers from load statistics in each flight so that we can sell at lower price with positive revenue. This figure was finally recognized by Airbus and Boeing but I think their struggle was trying to get other small operators in the world to understand since not everyone are able to understant the meaning of kg/hr/kg. This method was further expanded for measuring the ecomonic of scale in component selection, weight reduction projects, and even in aircraft selection. One small change triggers numerous benefits, it can change even change the world's perception.
