No FAA diagram published

The FAA does not publish an Airport Diagram (APD) for K4N1 — 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 K4N1

2 runway ends on file. Longest: 3,471 ft.

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.
