SAN ANTONIO INTERNATIONAL TOWER LETTER TO AIRMEN                   

SUBJECT: Twin Oaks Airport (T94): Recommended Departure Procedures

CANCELLATION: July 29, 2027

Twin Oaks Airport is located approximately 1½ nautical miles north of San Antonio International Airport, within the San Antonio Class “C” surface area. The proximity of these airports, and the runway configurations, have the potential to create situations which would require immediate action by controllers and pilots, to assure the “Safe” movement of air traffic within the San Antonio Class “C” airspace. In an effort to increase safety and provide the best possible service to the users, San Antonio Tower has developed a “Departure Procedure” for pilots departing the Twin Oaks Airport.

1. PRIOR TO DEPARTURE: 

CONTACT SAN ANTONIO CLEARANCE DELIVERY ON FREQUENCY 126.7 OR VIA TELEPHONE (210) 805-5516.  

State that you are on the ground at Twin Oaks, give your aircraft call sign, type aircraft, requested heading, requested altitude, which runway you intend to depart, and when you will depart. This will allow the pilot to obtain a transponder code and frequency for Radar Service. Additionally, it will alert San Antonio Tower Controllers that a departure from Twin Oaks is imminent.

2. WHEN YOU ARE READY TO DEPART: 

CONTACT SAN ANTONIO TOWER ON FREQUENCY 119.8. 

State you are at Twin Oaks, Runway 12 or 30, ready to depart. This will allow San Antonio Tower to adjust traffic to avoid conflict, and/or issue traffic and safety advisories in a timely manner.
