Very cool. One nit is because of the graph smoothing, it looks like you have negative hours P2 time 2014-2015 and Heavy time 2021-2022.
I thought the ICAO "Heavy" designation applied to aircraft above a certain MTOW instead of time? Wouldn't the time designation be as acting as relief captain/FO?
The term "Heavy" (for wake separation) in the ICAO context is 100% based on MTOW! In the context of this graph, these are flights where we carry 3 or 4 pilots, and I am not in the seat for takeoff or landing. We still operate at the control during the middle of the flight when the other pilots are on their rest break. Not sure where the name "Heavy" came from here, but is it just the term used at my airline (and probably others? Some use "relief crew")
Good call on the data smoothing - I will look into a fix for this!

In any case, great visualizations.
