THAYER AVIATION
GRIMES, CA
Thayer Aviation (53CN) is a privately owned, non-towered airfield in Grimes, California. The field's sole runway, NW/SE, is an asphalt strip 1,800 feet long and 60 feet wide.
Operations are conducted under visual flight rules, as no instrument approaches are published. The field lacks both a control tower and published advisory frequency, so all traffic coordination relies on standard see-and-avoid practice. No fuel service is available at the field. The private-use designation means landing requires the owner's prior authorization.
Field elevation is 54 feet above mean sea level.
