Prior Coordination Required:  Due to limited capacity and the sensitivity of air operations near a national monument, advance coordination is required. Submit coordination requests via fax to 618-337-1597 with the following information: Operator's name, phone number or other contact information, date and time of operation requested, aircraft type, registration number, pilot’s name, number of passengers, lead passenger’s name, services requested, and method of payment.

Confirm your approval to operate before landing via telephone at 618-337-6060 or via e-mail at rmcdaniel@stlouisdowntownairport.com.
Special Operating Procedures Apply: Do not overfly any portion of the Jefferson National Expansion Memorial (the National Park grounds include the land surrounding the arch and old courthouse.) For noise abatement, avoid overflight of the Soulard and Benton Park neighborhoods to the south. (Click here for a map of those neighborhoods.)

The Heliport has characteristics that require additional knowledge and specific operational procedures.

a. All normal approaches should be made from either the East or South. Approaches and departures should NOT be made to or from the west to avoid overflight of the the National Park grounds and people and vehicles on the levee.approach or departure be made to or from the west.

b. 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.

c. During times of high west winds, additional attention to the flight path on final approach is needed due to the Arch and buildings creating unusual wind currents that may require large power adjustments during approach.

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

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

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

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

h. Don't forget to contact "Downtown Tower" on 119.925 and DO NOT FLY OVER THE ARCH GROUNDS!
