BE IT ENACTED BY THE LEGISLATURE OF THE STATE OF MONTANA:
Section 1. (1) No For aircraft as defined in
subsection (2)(a), no entity, whether a division of government or a private company or corporation, may use
information broadcast or collected by automatic dependent surveillance-broadcast systems, whether that data
originates from ADS-B In or ADS-B Out, as a means for calculating, generating, and collecting fees from aircraft
owners or operators who operate aircraft within the geographic boundaries of the state.
(2) For the purposes of this section, the following definitions apply:
(a) "Aircraft" has the same meaning as provided in 67-1-101, except the aircraft must have a gross
weight of 9,000 pounds or less and operate under Title 14, part 91, Code of Federal Regulations.
(b) "Automatic dependent surveillance-broadcast" means an advanced aviation surveillance
technology that combines an aircraft's positioning source, aircraft avionics, and a ground infrastructure to create
an accurate surveillance interface between an aircraft and air traffic control. The term consists of two different
services, ADS-B In and ADS-B Out, that can provide information, such as an aircraft's global positioning system
location, altitude, ground speed, and other data, to ground stations and other aircraft, as well as weather and
traffic information to aircraft operators.
Section 2. [Section 1] is intended to be codified as an integral part of Title
67, chapter 1, part 1, and the provisions of Title 67, chapter 1, part 1, apply to [section 1].
