Nonstop flight route between Salmon, Idaho, United States and Shearwater, Nova Scotia, Canada:

About this route:

A direct, nonstop flight between Lemhi County Airport (SMN), Salmon, Idaho, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 2,426 miles (or 3,904 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 Lemhi County Airport and Shearwater Heliport, the route shown on this map most likely still appears to be a straight line.

Facts about Lemhi County Airport (SMN):

• The furthest airport from Lemhi County Airport (SMN) is Tôlanaro Airport (FTU), which is located 10,686 miles (17,197 kilometers) away in Tôlanaro, Madagascar.
• Lemhi County Airport (SMN) currently has only 1 runway.
• Because of Lemhi County Airport's high elevation of 4,043 feet, planes must typically fly at a faster airspeed in order to takeoff or land at SMN. Combined with a high temperature, this could make SMN a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• The closest airport to Lemhi County Airport (SMN) is Challis Airport (CHL), which is located 45 miles (72 kilometers) SSW of SMN.

Facts about Shearwater Heliport (YAW):

• Following a base rationalization program in the mid-1990s, the Canadian Forces closed CFB Shearwater as a separate formation and realigned the property's various facilities into CFB Halifax.
• 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.
• The closest airport to Shearwater Heliport (YAW) is Halifax Stanfield International Airport (YHZ), which is located only 17 miles (27 kilometers) N of YAW.
• 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.
• In addition to being known as "Shearwater Heliport", other names for YAW include "Halifax/Shearwater Heliport", "12 Wing Shearwater" and "CFB Shearwater".
• 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.
• 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.
• 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.
