Can someone supply the movements in a given week at EN with a breakdown of aircraft type?
Then it would be simple to calculate the total fuel burn (considering engine type) at takeoff fuel flow for 10-30 seconds that the aircraft would be over the surrounding suburbs (depending on aircraft type).
Then compare that with VicRoads data of the number of vehicles travelling along the Freeway. Calculate the cumulative fuel burnt in a week for all cars (east and west) travelling along the section of the freeway start at Bell St and finish at KPDrive in the west).
That should blow their argument out of the water. To rub salt into the wound, add the Tulla Freeway. Then add Bulla Rd, etc etc....
A call to arms - who can get this data?
It needs to be done properly and each source has to be referenced in a proper scientific manner. Remember you are not creating arguments against rational people, you have to have every i dotted and t crossed.
