Drawing stuff on a map with a GPS track is a rather beaten path in the world of Strava and similar [0]. Not being bound to the road network graph just makes it easier. I don't want to think about the fuel burned for this stunt, but if I were in some position that is required to sign off that flight path I'd sure congratulate whoever came up with this. Wouldn't even be all surprised if tomorrow some Airbus ferry flight would respond in the same medium with a respectful salute to the old lady.
([0] but relative to anything that would be considered a tradition in aviation, the entire concept of GPS is rather newfangled, despite it's surprising age, I'm not disagreeing)
- mulmen 4y agoI don't think this uses GPS, at least not directly. This data comes from ADS-B and radar. ADS-B involves the plane itself broadcasting where it (thinks it) is. That may come from GPS onboard but is probably more sophisticated than that in a modern 747.
- snuxoll 4y agoThe ADS-B out data is fed from the aircraft’s ADIRU (air data inertial reference unit), which, yes, just uses GPS unless that fails for some reason. There’s a fallback based on accelerometers and laser gyros to provide shockingly accurate positioning should such a failure occur, but it does lose some accuracy (enough that you can still fly autopilot on it for an approach at max range, but it’ll be drifting by some number of meters) over long flights before it needs to be reset from GPS data on the ground.
