I'm trying to create a map of arrivals and departures from a given airport across a single day. I'm attempting to do this purely using the REST API so I don't need to download a huge amount of raw states and process it myself. I'm able to get a list of all departures and arrivals from a given airport using /flights/arrival and from what I can tell the simplest method of getting clean tracks of aircraft positions is to use the /tracks/all endpoint.
The problem I have is that there are a lot of arrivals and departures at some airports (eg. 1,200 at London Heathrow in one day) and the /tracks/all endpoint only takes one aircraft per request.
Is there a way to request the tracks for multiple aircraft in one request? Or is my only option to send a single request per (all 1,200) aircraft? If the latter, is there a limit on how many requests I can make to /tracks/all?
As an aside, is there a simpler method for getting the states / traces for all aircraft that arrived / departed from a given airport on a given day?
