Our History

Providing Charters and Instruction Since 2017

Best Flight School NW Mountain Regions 2021-2022

AOPA Flight Training Survey

Voted best flight school in the Northwest Mountain Region

Ridgeline Aviation has been recognized for its excellence in flight training by the Aircraft Owners and Pilots Association(AOPA), the world’s largest aviation association. The flight school has been awarded the title of Best Flight School in the Northwest Mountain Region 2021-2023 and is the only flight school in the Northwest Mountain Region to earn this recognition.

The Flight Training Experience Survey was created to highlight the best flight training the industry has to offer. “Successful flight training is about more than just learning to fly. Building a sense of community to support the people who are learning takes the experience to a much higher level where they can excel. This year’s instructors and schools have clearly brought their customers into the pilot community,” said AOPA Foundation Sr. Director Flight Training Education Chris Moser.

The 2023 awards were drawn from flight students and pilots who voluntarily reviewed their flight training experience this past summer through an AOPA online customer satisfaction survey. The process yielded an evaluation of 608 different flight schools and 1,153 individual flight instructors. Learn more: www.aopa.org/FTawards
