GELFIUS INTL
DAHLGREN, IL
27IS is the identifier for Gelfius International, a privately owned, non-towered airfield in Dahlgren, Illinois. A single turf runway, 13/31, serves the field at 1,800 feet long and 70 feet wide.
No instrument approach procedures are published, so the field is used under visual flight rules. Pilots coordinate their own arrivals and departures using see-and-avoid procedures. The field has no fuel sales on record. Its private-use designation means the owner's permission is needed before landing.
The airport sits at 530 feet above mean sea level.
