MERKLE
HANOVER, IL
Merkle, identified as 3IS4, is a privately owned, non-towered airfield in Hanover, Illinois. A lone turf runway, 18/36, serves the field, measuring 2,900 by 100 feet.
No published instrument approach procedures exist, so the field is used under visual flight rules. The non-towered field operates under see-and-avoid procedures, with pilots coordinating their own arrivals and departures. The field has no fuel sales on record. Its private-use designation means pilots need the owner's permission before landing.
The airport sits at 970 feet above mean sea level.
