St. Louis Downtown Heliport Information

Get a bird’s-eye view of the beautiful city of St.Louis and beyond.

The St. Louis Downtown Heliport is located on top of a 175 foot by 54 foot deck barge that is moored on the Mississippi River levee, 50 feet north of the Gateway Arch.  The heliport is the only Federal Aviation Administration-approved floating heliport located on an inland waterway.  The heliport is available during daylight hours under visual flight rules.  The heliport will accommodate two helicopters simultaneously, therefore prior coordination is required before operating to or from the heliport. Landing and parking fees apply. (Long-term parking and services are available three miles SE at the St. Louis Downtown Airport (Federal Aviation Administration Identifier Code – CPS).

Special Operating Procedures Apply: Do not overfly any portion of the Jefferson National Expansion Memorial (the national park grounds include the land surrounding the Gateway Arch and Old Courthouse.)

Normal Approaches

All normal approaches should be made from either the east or south. Approaches and departures should NOT be made on the west side to avoid overflight of the the national park grounds and people and vehicles on the levee.

Flight Paths

 Flight paths for take-off and landing should be parallel to the shoreline for emergency landing areas. Routine approaches/departures perpendicular to the river channel should be avoided for safety reasons.

High West Winds

During times of high west winds, additional attention to the flight path on final approach is needed due to the Gateway Arch and buildings creating unusual wind currents. As a result, it may be required to make large power adjustments during approach.

Flight Under Bridges

Flight under bridges should be avoided during normal operations. (During an emergency, flight under a bridge may be your safest option – use it if needed! If you fly under a bridge, be prepared to provide detailed written documentation of the situation, if requested.)

Lift Off

The pilot should not lift off until they have been “cleared” by the “thumbs up” sign from the heliport attendant (if present).

Heliport Usage

The heliport is to be used for passenger or cargo loading and unloading only. This restriction is due to the limited number of parking spots available. Long-term parking, overnight parking, and other services are available nearby at the St. Louis Downtown Airport (CPS).

Unauthorized Personnel

No unauthorized persons will be allowed on the flight deck. All passengers must be escorted to and from the aircraft by the pilot or heliport personnel.
