Nonstop flight route between Tucson, Arizona, United States and Shearwater, Nova Scotia, Canada:

About this route:

A direct, nonstop flight between Davis–Monthan Air Force Base (DMA), Tucson, Arizona, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 2,664 miles (or 4,288 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 large distance between Davis–Monthan Air Force Base and Shearwater Heliport, the route shown on this map most likely appears curved because of this reason.

Try it at home! Get a globe and tightly lay a string between Davis–Monthan Air Force Base and Shearwater Heliport. You'll see that it will travel the same route of the red line on this map!

• The base was named in honor of World War I pilots Lieutenants Samuel H.
• On 1 September 1982, the headquarters of the 602nd Tactical Air Control Wing and its subordinate 23rd Tactical Air Support Squadron, a unit responsible for the Air Force's tactical air control system west of the Mississippi River transferred from Bergstrom Air Force Base, Texas, and stood up at D-M, bringing 16 OA-37B aircraft and numerous new personnel to the base.

Facts about Shearwater Heliport (YAW):

• Beginning in the 1970s, CFB Shearwater began hosting an Armed Forces Day every fall, typically on the weekend following Labour Day, and included an air show where the long and wide runways at Shearwater hosted some of the largest aircraft in the world, including the U.S.
• Base rationalization and defence budget cutbacks for the Canadian Forces during the mid-1990s saw a largely administrative move when the formation CFB Shearwater stood down and the facilities transferred to the formation CFB Halifax and aircraft operations becoming the responsibility of newly formed 12 Wing.

• Because of Shearwater Heliport's relatively low elevation of 144 feet, planes can take off or land at Shearwater Heliport 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.
• As part of the heliport conversion project, the old runway 16/34 was permanently closed and placed outside of a new fence for the Shearwater Heliport, as shown in the Canada Flight Supplement effective 31 July 2008.
