Portland Troutdale Airport — Portland, United States

Portland Troutdale Airport, coded TTD, is a general aviation facility located east of Portland, Oregon, in the city of Troutdale near the Columbia River Gorge. Unlike major commercial airports, TTD focuses on private aviation, flight training, and small charter operations, making it a busy hub for the region's recreational and student pilots. The airport features two runways and hosts several flight schools, aircraft maintenance businesses, and hangars for locally based aircraft. Its proximity to scenic destinations like Multnomah Falls and the Gorge makes it popular for sightseeing flights. TTD relieves congestion at Portland International Airport by absorbing general aviation traffic, and it plays a meaningful role in Oregon's broader network of community airports serving pilots and small aircraft owners.
