The main purpose of the Pilot and Aircraft Privacy Act of 2025 is to protect the privacy of aircraft owners and operators by limiting how data from automatic dependent surveillance-broadcast (ADS-B) systems can be used. This legislation aims to ensure that this data cannot be exploited for financial gain without the owner's consent, while still allowing air traffic controllers to use it for safety and efficiency purposes. Key provisions of the Act include restrictions on the use of ADS-B data.
