Nonstop flight route between Portsmouth, Ohio, United States and Shearwater, Nova Scotia, Canada:

About this route:

A direct, nonstop flight between Greater Portsmouth Regional Airport (PMH), Portsmouth, Ohio, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 1,071 miles (or 1,724 kilometers).

A Great Circle is the shortest distance between 2 points on a sphere. Because most world maps are flat (but the Earth is round), the route of the shortest distance between 2 points on the Earth will often appear curved when viewed on a flat map, especially for long distances. If you were to simply draw a straight line on a flat map and measure a very long distance, it would likely be much further than if you were to lay a string between those two points on a globe. Because of the relatively short distance between Greater Portsmouth Regional Airport and Shearwater Heliport, the route shown on this map most likely still appears to be a straight line.

• Because of Greater Portsmouth Regional Airport's relatively low elevation of 663 feet, planes can take off or land at Greater Portsmouth Regional Airport at a lower air speed than at airports located at a higher elevation. This is because the air density is higher closer to sea level than it would otherwise be at higher elevations.
