Air Tour Management Plan

Glacier National Park » Air Tour Management Plan » Document List

The National Park Service (NPS) and Federal Aviation Administration (FAA) have prepared a draft Air Tour Management Plan (ATMP) for Glacier National Park to delineate acceptable levels of commercial air tours, including, but not limited to, frequency, duration, altitude, and routes, consistent with the National Parks Air Tour Management Act of 2000. The ATMP is consistent with the Park's 1999 General Management Plan and subsequent planning efforts in that it includes a provision on phasing out air tours through attrition. The plan is on public review until October 3, 2021. The proposed action, background and purpose are described below.

Proposed Action:

Commercial air tours are currently conducted at Glacier as described under the "Existing Conditions" section below. The proposed action is to implement an Air Tour Management Plan (ATMP) that would delineate acceptable levels of commercial air tours including, but not limited to, frequency, duration, altitude, and routes, consistent with the National Parks Air Tour Management Act of 2000 (Act). Congress developed the Act out of concern that noise from tour aircraft could harm national park resources and experiences for visitors.

Background and Purpose:

The Act, as amended, requires that all commercial air tour operators conducting or intending to conduct a commercial air tour operation over a unit of the National Park system apply to the Federal Aviation Administration (FAA) for authority to undertake such activity. The Act further requires the FAA, in cooperation with the National Park Service (NPS), to establish an ATMP or voluntary agreement for each park that did not have such a plan or agreement in place at the time the applications were made, unless a park has been otherwise exempted from this requirement.

The Act applies to areas within and 1/2 mile outside of a park, and to elevations below 5,000 feet above ground level (AGL). The Act requires that an ATMP include incentives for the adoption of quiet aircraft technology and provide for the allocation of opportunities to conduct air tours when the ATMP limits the number of operations. An ATMP may prohibit commercial air tour operations (in whole or in part), and can establish conditions for the conduct of air tour operations (including routes, altitudes, time-of-day restrictions, restrictions for particular events, maximum numbers of flights, or other provisions).

In establishing an ATMP, the Act requires the agencies to publish the proposed plan for notice and comment and hold at least one public meeting. The public meeting for this ATMP will be held on September 21, 2021, and comments on this ATMP will be accepted until October 3, 2021. Air tours at the Park have been ongoing since before the Act was enacted. The Act directed the FAA to grant interim operating authority (IOA) to operators that were already conducting tours at the Park when the Act became effective until an ATMP is developed. An operator's IOA is based on the number of flights the operator reported it was conducting annually at the time the Act was passed. IOA does not set routes or operating conditions for an operator except to limit the number of air tours the operator is permitted to fly each year. Implementation of an ATMP will replace IOA.

Existing Conditions for Commercial Air Tours at Glacier National Park

Three commercial air tour operators, Homestead Helicopters, Inc., Minuteman Aviation, Inc., and Red Eagle Aviation, Inc. (DBA Montana Air Adventures) currently conduct commercial air tours at Glacier National Park. The operators hold IOA for a combined total of up to 891 flights at the Park each year. Homestead Helicopters, Inc., holds IOA for 15 flights at the Park each year, Minuteman Aviation, Inc., holds IOA for 717 flights at the Park each year, and Red Eagle Aviation, Inc. holds IOA for 159 flights at the Park each year. Two additional operators, Montana By Air LLC and Kruger Helicopter Service previously held IOA at the Park and conducted commercial air tours at the Park in 2017-2019, however, these operators surrendered their operating certificates in 2021. Based on the three-year average of reporting data from 2017-2019, the operators (including those with surrendered operating certificates) conducted an average of 253 flights at the Park each year; excluding those operators with surrendered operating certificates, the three-year average equates to 144 flights at the Park each year. Homestead Helicopters, Inc. did not provide commercial air tour route information in response to a 2017 request from the FAA and the NPS. The operator conducts commercial air tours using a BHT-407-407 rotorcraft. Minuteman Aviation, Inc. conducts commercial air tours on one route within the Park using BHT-206-B, BHT-206-B3, BHT-206-L3, BHT-206-L4, BHT-210-210, BHT-407-407, and CE-182-P aircraft (fixed-wing and rotorcraft). Red Eagle Aviation, Inc. also conducts commercial air tours on one route within the Park using BELL-206-L3, CE-206-U206E, CE-206-U206G aircraft (fixed-wing and rotorcraft). Altitude expressed in AGL units is a measurement of the distance between the ground surface and the aircraft, whereas altitude expressed in mean sea level (MSL) units is a measurement of the distance between sea level and the aircraft. The operators conduct commercial air tours between 7,500 and 10,000 feet (ft.) MSL, which corresponds to an estimated above ground level (AGL) range between 500 and 6,800 ft. Commercial air tours may occur at any time and on any day of the week.

Under existing conditions, the annual number of commercial air tours at Glacier National Park is limited by the IOA; however, there are no designated parameters on route, time-of-day, or altitude restrictions to further protect Park resources or visitor experience. Currently, no procedures are in place that allow the Park to establish no-fly periods for special events or planned Park management. The provisions and conditions in the proposed ATMP address these parameters in a manner designed to protect Park resources and visitor experience from the effects of commercial air tours and support NPS management objectives for the Park.


Several federally threatened/endangered species are present/have critical habitat in the project area. The NPS and FAA have begun informal consultation with the United States Fish and Wildlife Service (USFWS) and anticipates a determination of no effect for all species.

Section 106 of the National Historic Preservation Act (NHPA)

Pursuant to 36 CFR 800.2(a)(2), the FAA has been designated the lead Federal agency acting on behalf of the NPS and is fulfilling the collective responsibilities of both agencies under Section 106 of NHPA. Section 106 consultations are ongoing.
