The Air Care Alliance is a nonprofit organization, chartered as a 501(c)(3) group, and thus it serves the public benefit first. ACA exists to support and promote Public Benefit Flying so that patients and others can learn about the services provided by volunteer pilots and charitable aviation groups and so that information can be shared among the groups, improving the quality of their services and the safety of their flights. ACA encourages communications and cooperation among all PBF organizations in order that their members share experiences and learn from one another. ACA has held annual "Air Care" conferences since 1990 where leaders in Public Benefit Flying gather to meet one another and learn the latest about this charitable activity.
