Part 34 Emissions Standards

Definition

Part 34 emissions standards refer to regulations set by the Environmental Protection Agency (EPA) that govern the allowable emissions of air pollutants from aircraft engines. These standards are essential in reducing the environmental impact of aviation by limiting harmful pollutants released into the atmosphere, ensuring that aircraft meet specific performance and safety criteria while operating under these constraints.
