John F Kennedy International (KJFK)

John F Kennedy International has four runways in two crossing pairs on the edge of Jamaica Bay. The longest is 13R/31L at 14,511 feet, and the field connects a dense domestic network with long-haul international arrivals.

JFK's FAA traffic-management guidance publishes several mixes of the 4s, 22s, 31s and 13s; this board gives each a distinct, simplified flow. JetBlue, Delta and American are the largest modeled streams, while European, Gulf and Asian carriers add long-haul aircraft. The routes and weights are calibrated for varied shifts, not a replay of a daily timetable.

This is the Heavy tier: crossing pavement, departure banks and tightly sequenced finals. The published Class B shelves and supported instrument procedures are present; coordination with Newark and LaGuardia, simultaneous-approach monitor positions and the detailed surface operation are outside this seat.
