WiFi without internet on a Southwest flight

Interesting how they chose to make more general `vehicleId` instead of `planeId` or `tailNumber` or something. I wonder if Delta's fleet includes other things that have matching APIs to this one. I also wonder how much of their internal system structure one could learn from the `flightId` if they knew about other systems. It doesn't look like much beyond a composite key of otherwise knowable data, but still interesting.

I doubt Delta made this. It’s an official the shelf product that can do ships, trains, planes, etc.

Valid point. It makes a lot of sense in that light instead.

But they also have airplane/flight specific identifiers like “flightNumber”, “flightId”, “noseId(?)” and “airSpeed”. Maybe vehicleId is part of a base class or primary key somewhere and that abstraction is leaking.

Hey, a train has airspeed. :)

Heh, true. I deliberately left out altitude because this is HN but you caught me anyway.

Presumably a train's groundSpeed and airSpeed are the same. If they diverge you have bigger problems than a JSON schema.

Is there a variant of this for ships? surfaceSpeed vs seaFloorSpeed?

A train can easily run in a head- or tailwind in the same order of magnitude as its groundspeed.

I've been tempted to mount a small anemometer to my car - by subtracting the groundspeed from the measured airspeed, one can get the wind speed and direction and figure out whether there is a headwind or tailwind and if so how strong. Theoretically this could be used to drive more efficiently, though the extra drag from the anemometer would probably cancel out any gains.

Wow I got HN’ed twice in one thread. This is not my day.

Well, ships have apparent wind vs real wind and apparent course vs real course (currents and drift are a thing).

Those could apply to an air taxi service or something using helicopters as well.

"Official the shelf" - that your new iOS 17 update helping you out? ;)

Not all aircraft are planes.
