Final answer:
The Canadian Minimum Navigation Performance Specification Airspace (CMNPSA) is located over Canada, primarily east of the 80 degrees west longitude and above 29,000 feet, to facilitate safe and efficient air traffic management for transatlantic flights.
Step-by-step explanation:
The Canadian Minimum Navigation Performance Specification Airspace (CMNPSA) is an airspace region over Canada where aircraft are required to adhere to specific navigation performance standards. This airspace is designated to facilitate efficient air traffic management and enhance safety for transatlantic flights. It is located in the region of Canadian airspace that is used for transatlantic flights, primarily east of the 80 degrees west longitude and above 29,000 feet. This includes a large portion of the airspace over the North Atlantic where a significant amount of international air traffic between North America and Europe passes. The CMNPSA requires aircraft to be equipped with certain navigation systems that meet the minimum performance specifications, ensuring that aircraft can maintain more precise flight paths.
