Nonstop flight route between Shearwater, Nova Scotia, Canada and Attu Island, Alaska, United States:

About this route:

A direct, nonstop flight between Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada and Casco Cove Coast Guard Station (ATU), Attu Island, Alaska, United States would travel a Great Circle distance of 4,913 miles (or 7,907 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 Shearwater Heliport and Casco Cove Coast Guard Station, 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 Shearwater Heliport and Casco Cove Coast Guard Station. You'll see that it will travel the same route of the red line on this map!

Facts about Shearwater Heliport (YAW):

• Defence cutbacks and unit and facility realignments from 1994 to 1996 saw CFB Shearwater stand down as a separate formation and the facility merged as an airfield attached to CFB Halifax.
• Post-war, 1948, the Royal Canadian Navy took over the facility, naming it HMCS Shearwater, also known as Royal Canadian Naval Air Station Shearwater.
• In addition to being known as "Shearwater Heliport", other names for YAW include "Halifax/Shearwater Heliport", "12 Wing Shearwater" and "CFB Shearwater".
• The furthest airport from Shearwater Heliport (YAW) is Albany Airport (ALH), which is located 11,763 miles (18,931 kilometers) away in Albany, Western Australia, Australia.
• The closest airport to Shearwater Heliport (YAW) is Halifax Stanfield International Airport (YHZ), which is located only 17 miles (27 kilometers) N of YAW.
• 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.
• These changes allowed for heliport operations including instrument approaches and were accompanied with the construction of other non-airfield facilities in support of the Maritime Helicopter Project.
• By the 1980s this air show came to be named the "Shearwater International Air Show" and was a popular event for military aviation enthusiasts in Eastern Canada and the Northeastern United States as the location of CFB Shearwater, coupled with the popularity of the Halifax area among military aircrew, resulted in heavy international participation from the RCAF, as well as the USAF, United States Navy, United States Marine Corps, Royal Air Force and numerous other NATO air forces in Europe.
• The inconvenience of not having a ground component for the "Nova Scotia International Air Show" as a result of the Shearwater Heliport Conversion Project saw the entire event moved to Halifax Stanfield International Airport beginning in 2004.

• Because of Casco Cove Coast Guard Station's relatively low elevation of 88 feet, planes can take off or land at Casco Cove Coast Guard Station 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.
• The island is protected as part of the National Parks Trust territory and few people visit the island or area, as it is restricted.
