Airspan (FlightQ)

Airspan is FlightQ's size-estimation game. A blue reference is shown at a known scale: a football pitch, a park, a landmark such as the Empire State Building, a car, the Space Shuttle Discovery or another plane. Beside it sits an orange aircraft or airport, and you pinch or drag its handle to resize it until the proportion looks right. Aircraft are compared by overall length; airports by the mapped area of their grounds.

When you press Guess, the orange shape smoothly resizes to its true size next to a dashed outline of your guess, and you score up to 100 points for the round. Facts and dimensions, such as an aircraft's wingspan, open after each reveal. A streak counts guesses within 90 percent of the true proportion.

Aircraft and Airports each have their own five-round daily challenge, the same comparisons for everyone, refreshing at midnight Eastern. The collection covers 42 aircraft configurations, modern, historical and in development, and 500 major airports in 115 countries and territories. An archive holds past days: today's and yesterday's challenges are free, and FlightQ Premium unlocks older ones and removes the ads. Airspan says it was inspired by Magnitudle's Size It Up.
