Nonstop flight route between Mammoth Lakes, California, United States and Shearwater, Nova Scotia, Canada:

About this route:

A direct, nonstop flight between Mammoth Yosemite Airport (MMH), Mammoth Lakes, California, United States and Shearwater Heliport (YAW), Shearwater, Nova Scotia, Canada would travel a Great Circle distance of 2,864 miles (or 4,610 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 Mammoth Yosemite Airport 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 Mammoth Yosemite Airport and Shearwater Heliport. You'll see that it will travel the same route of the red line on this map!

Facts about Mammoth Yosemite Airport (MMH):

• The closest airport to Mammoth Yosemite Airport (MMH) is Eastern Sierra Regional AirportBishop Army Airfield (BIH), which is located 31 miles (50 kilometers) ESE of MMH.
• Because of Mammoth Yosemite Airport's high elevation of 7,135 feet, planes must typically fly at a faster airspeed in order to takeoff or land at MMH. Combined with a high temperature, this could make MMH a "Hot & High" airport, where the air density is lower than it would otherwise be at sea level.
• Mammoth Yosemite Airport (MMH) currently has only 1 runway.
• The furthest airport from Mammoth Yosemite Airport (MMH) is Pierrefonds Airport (ZSE), which is located 11,259 miles (18,120 kilometers) away in Saint-Pierre, Réunion.
• The airport had 665 passenger boardings in calendar year 2008, 6,157 enplanements in 2009, and 19,814 in 2010.

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.
• In addition to being known as "Shearwater Heliport", other names for YAW include "Halifax/Shearwater Heliport", "12 Wing Shearwater" and "CFB Shearwater".
• 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.
• 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.
• 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.
• 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.
• 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.
• Organizers of the "Nova Scotia International Air Show" continued to make use the Shearwater airfield for both ground displays and the air show component until 2002.
