No FAA diagram published

The FAA does not publish an Airport Diagram (APD) for KGAI — most non-towered fields, heliports, seaplane bases, and private strips fall here. Below: aerial imagery showing the actual field, runways, taxiways, and surroundings.

Runways at KGAI

2 runway ends on file. Longest: 4,202 ft. Max gradient: 1.08% (noticeable slope — affects performance)

Designator Heading Length Width Surface Lighting Gradient
14 127.4° 4,202 ft 75 ft ASP Yes 1.08%
32 307.4° 4,202 ft 75 ft ASP Yes 1.08%

Source: in-app airport database (runway lengths + headings), OurAirports for surface, width, lighting. Gradient computed from FAA NASR runway-end elevation deltas (the published RWY_GRAD field is empty in 99.99% of NASR rows; we derive it from the elevations the FAA does publish).

The honest comparison — events normalized by exposure. A field doing 4× the operations will see more events at the same per-op rate. Per million ops is what matters.
