Improve flight model by adding fuel consumption curve by aircraft type

Data found here: https://www.eea.europa.eu/publications/emep-eea-guidebook-2019/part-b-sectoral-guidance-chapters/1-energy/1-a-combustion/1-a-3-a-aviation-1/view

Great dataset to cover most of the worlds commercial flights!!! :) It could be connected with highly detailled flight data from services like https://www.flightradar24.com/ (there are other data providers, too, afaik) for individual flights. Thinking in another direction, I can imagine this could become something real-time like "the electricityMap for flying" by showing the approximated CO2_eq emissions of each flight as a trail behind the airplanes ;)

@martincollignon I'd love to help with this issue if possible

[martincollignon]

@andrewb39 go ahead! @ayakoaohara there is still #273 and #250 ;-)

@andrewb39 are you on it? :)

[pierresegonne]

@martincollignon is there one data source that should be preferred over the other?

From what I see:

Source	Pros	Cons
EAA	Excel File, so could automate	Uses some macro and might prevent easy scripting
ICAO	UN dependent, so might be more accurate?	Pdf (-> there might be a database somewhere?)

[martincollignon]

definitely more EAA actually - there are a few models where we may need ICAO though. it'd be interesting to see if there is a massive difference.

I would like to help if still needed @martincollignon :) (First-timer)

[martincollignon]

Great to see so many people helping! When do you think you can work on it?

[NoamAv1]

@martincollignon From tomorrow morning I can start

[martincollignon]

Sounds perfect! Go ahead!

Hey, just made a json file for the fuel burn by the aircraft type, is it okay? Here

[martincollignon]

Hi @NoamAv1 ! Good first pass. What we would actually need is the function of fuel consumption by distance by plane model.

The fuel consumption is currently determined by this function: https://github.com/tmrowco/northapp-contrib/blob/master/co2eq/flights/index.js#L77 : ((a(isShortHaul) distance distance) + (b(isShortHaul) * distance) + c(isShortHaul))

This function needs to be changed so it accepts an optional plane model to take into account the actual plane model's fuel consumption depending on distance in kilometer.

The function ((a(isShortHaul) distance distance) + (b(isShortHaul) * distance) + c(isShortHaul)) will still be used as a fallback.

[NoamAv1]

Hey @martincollignon , I started not long ago my semester so I could get to work on it but now I'm available to work again I couldn't really figure from where I can see what variables I need for the function and what is the calculation for this function I looked at both of those files and couldn't really figure it out by myself. We can continue the talk in private if you would like to :)

[pierresegonne]

Any update on this? Does the activity contain any information about the plane model? If no is there a plan to include it and what needs to be done for it to happen? @martincollignon

[martincollignon]

We would need to add a plane model variable within the activity model. I actually do not know whether there is this data coming from for example Tripit, Ryanair or others.
