Nonstop flight route between Shearwater, Nova Scotia, Canada and St. Helens, Tasmania, Australia:

About this route:

A direct, nonstop flight between Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada and St Helens Airport (HLS), St. Helens, Tasmania, Australia would travel a Great Circle distance of 10,825 miles (or 17,421 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 St Helens Airport, 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 St Helens Airport. You'll see that it will travel the same route of the red line on this map!

Facts about Shearwater Heliport (YAW):

• 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".
• 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.
• 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.
• 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.
• 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.
• The closest airport to Shearwater Heliport (YAW) is Halifax Stanfield International Airport (YHZ), which is located only 17 miles (27 kilometers) N of YAW.
• 12 Wing's squadrons at Shearwater Heliport in Nova Scotia and at Patricia Bay in British Columbia currently operate the Sikorsky CH-124 Sea King but is expected to re-equip with the Sikorsky CH-148 Cyclone commencing in 2012 with the conclusion of the Maritime Helicopter Project.
• Shearwater Heliport's primary mission remains as a heliport in support of the Royal Canadian Navy's Maritime Forces Atlantic warships with shipborne helicopters operated by 12 Wing, a unit of the Royal Canadian Air Force.

Facts about St Helens Airport (HLS):

• The furthest airport from St Helens Airport (HLS) is Corvo Airport (CVU), which is nearly antipodal to St Helens Airport (meaning St Helens Airport is almost on the exact opposite side of the Earth from Corvo Airport), and is located 12,317 miles (19,823 kilometers) away in Corvo Island, Azores, Portugal.
• St Helens Airport (HLS) currently has only 1 runway.
• Because of St Helens Airport's relatively low elevation of 158 feet, planes can take off or land at St Helens 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.
• The closest airport to St Helens Airport (HLS) is Launceston Airport (LST), which is located 57 miles (92 kilometers) WSW of HLS.
