PlaneQ

PlaneQ is one of the daily aviation games on FlightQ. Two puzzles go live each day. Current uses dated published fleet counts for aircraft flying today, with airlines listed fewest first. Historic covers classic airliners such as Concorde, the DC-10, the L-1011 and the 747 Classic, with operators past and present including Pan Am and TWA. Each mode keeps its own streak.

You build your own clues. For each of five slots you choose either an airline that flies the type or an aircraft fact: cabin layout, engines, wing position, first airline service or a passenger-capacity example. Your first clue and the clue after a wrong guess are free; extra clues use one of your five attempts, and the last attempt is always a guess. A wrong guess tells you whether you had the right manufacturer, and the maker then locks in.

Variants are grouped, so every A321 is just Airbus A321 and every 737 from the -800 to the MAX is Boeing 737. Every daily puzzle is free with no account. The page shows display ads beside the board on desktop and a banner above it on phones; FlightQ Premium removes them and adds unlimited practice, advanced stats and the archive of past puzzles. PlaneQ is also inside the FlightQ app for iPhone and Android, which holds all of FlightQ's daily games.

It suits aviation fans who know which airlines fly what, and pairs with FlightQ's SkyQ, where you guess a flight route instead.
