What runway does 16G offer for business aviation arrivals?
Seneca County Airport (16G) has a single paved runway, 06/24, measuring 4,000 feet long and 75 feet wide with an asphalt surface. This is the only runway available at the field, so aircraft performance planning should be based entirely on this configuration. There is no parallel or crosswind runway option at this airport.
Is customs clearance available on-site at 16G?
Seneca County Airport (16G) does not have customs service on the field. The nearest customs facility is located at KPCW, approximately 29.7 nautical miles away. Aircraft requiring customs clearance in this area should plan to route through that facility rather than Seneca County directly, and inbound flights needing clearance direction are advised to contact Toledo Approach.
