✈️ Aircraft

The footprint of the plane is substantial. It is not necessarily more polluting per kilometer than a car that only moves one person, but the distance and especially the distance covered in one hour (commonly called speed), allows to change continent for a weekend.

Let's also keep in mind that the average French person does not fly or does not fly much. Most of the aviation footprint is therefore concentrated on 10% or less of the French population.

For the definition of flight ranges, from short-haul to long-haul, we use this discussion from the Base Carbone forum.

We have chosen to ask for the total number of flight hours, rather than asking the user to fill in each of his flights via the departure and arrival airports and the economy class. This is a possible evolution later, see this simulator where part of the work is already done.

Note also that stopovers lead to additional takeoffs, which consume more fuel than a cruising speed. This is also a parameter to take into account later.

For a more detailed model of the aircraft's footprint, we found two sources.
