Editorial Aerodrome Deep Dive: Jacksonville International Airport (JAX)

Curated Aerodrome Profile

Jacksonville International Airport serves as Northeast Florida's commercial and aerospace hub. Located at 30 ft MSL on coastal pine flatwoods, JAX offers ideal sea-level air pressure, ensuring high engine thrust efficiency for departing commercial transports. The 10,000 ft primary runway provides generous landing rollout safety margins during heavy summer Atlantic thunderstorm downpours.

Runway Layout & Magnetic Alignments
Dual non-intersecting perpendicular runways: Runway 08/26 (10,000 ft / 3,048 m) and Runway 14/32 (7,701 ft / 2,347 m).
Expansion Milestones & Predecessor Facilities
Opened in 1968 replacing the older Imeson Field. Co-located with the 125th Fighter Wing of the Florida Air National Guard, flying F-15 and F-35 air superiority fighters.
Regional Differentiation & Cluster Role
Primary commercial aviation facility in Northeast Florida, situated 56 NM north of St. Augustine (UST) and 60 NM south of Brunswick (BQK).
Data Nuances & Operational Quirks
Runway 08/26's 10,000 ft concrete pavement supports military fighter scrambles, heavy defense logistics, and commercial passenger airline banks.
