Aerial view · KEKS

No FAA diagram published

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

2 runway ends on file. Longest: 7,600 ft. Max gradient: 1.10% (noticeable slope — affects performance)

Designator Heading Length Width Surface Lighting Gradient
16 176.6° 7,600 ft 100 ft ASP Yes 1.10%
34 356.6° 7,600 ft 100 ft ASP Yes 1.10%

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).
