The purpose of ACA is to bring together all persons who represent both publicly and privately owned airports, and all others working to foster, promote and assist the development of air transportation in the State of California through the dissemination of aeronautical information, the consideration and solution of various airport and aviation problems, and the fostering of public recognition of airports and the airport management profession. ACA is devoted to drawing membership from all airports in the State and take advantage of all human resources available from those airports. Therefore, membership is not restricted to full time airport management personnel. Membership is open to all levels and degrees of airport management such as City Managers, Public Works Directors, Airport Land Use Commission members and owners of private airports. ACA will represent these persons and all others involved with airports on issues that are of statewide importance. ACA continues to actively seek the participation of the airport-related industry in determining issues that need to be addressed for the betterment of all airports, large and small and the individuals and companies that rely on them. Airport consultants, engineering firms and airport-based businesses are regarded as an essential part of this association. This unique and diverse “Partners in Aviation" approach has already made ACA's position stronger in our dealings with important industry issues. Our strength comes from our diverse membership and their active participation. However, to continue with our success we look for new member participation to make ACA an erudite and strong voice for California airports. Click here for home page
