Unmanned Aircraft Systems

Caltrans Division of Aeronautics has created this portal to provide relevant and timely information on Unmanned Aircraft Systems (UAS) operations within California's airspace.

A UAS ("drone") is any unmanned aircraft and all of the associated support equipment (remote control, communication equipment, data link, etc…) necessary to operate the unmanned aircraft. Prior to operating a UAS within five miles of an airport, users must notify the airport authority and Federal Aviation Administration (FAA) Air Traffic Control.

New UAS users should visit the Know Before You Fly campaign developed by the Association for Unmanned Vehicle Systems International (AUVSI) and the Academy of Model Aeronautics (AMA) in partnership with the Federal Aviation Administration (FAA).

Federal Aviation Administration UAS Resources

The Federal Aviation Administration's (FAA) UAS website provides information on the operations of UAS including registration, Certificate of Authorization (COA), Section 333 Exemption, Special Air Worthiness Certificate, and operator requirements.

UAS Registration:

Effective December 21, 2015, anyone who owns a UAS weighing more than 0.55 lb. and less than 55 lbs. must register with the FAA UAS Registry.  UAS Registration costs $5 and is valid for three years. UAS owners who do not register could face civil and criminal penalties.

FAA Smartphone App:

The FAA has developed a smartphone app- B4UFLY App that helps UAS operators determine whether there are any restrictions or requirements in effect at the location where they plan to operate a UAS. Know Before You Fly is an educational campaign by the Association for Unmanned Vehicle Systems International (AUVSI).

UAS Regulations and Policies

The Federal Aviation Administration (FAA) is the sole regulatory authority over the National Airspace System. FAA jurisdiction over UAS operations was set forth by the FAA MODERNIZATION AND REFORM ACT OF 2012.
