To assess distance traveled, the great circle distance
between cities where sequential games were played was calculated.
On the qibla instruments, the cities are placed at distances proportional to the sine of the great circle distance
to Mecca in order to maintain the correct direction to Mecca.
The greater the diameter of the circle, the lower the altitude of the star, for as mentioned earlier the great circle distance
from observer to Geographical Position in angular units gives the coaltitude (90 |degrees~ -- altitude).
The flight, captained by Action Aviation's Chairman Hamish Harding and co-pilot Emivest Aerospace's Bryan Dennison, covered a great circle distance
of 3470 statute miles route (5600 km) giving an average speed of 488 mph (786 km/h).
Since the rectangle diagonal (of length D = 4R, where It is the sphere's radius) is transformed into a semicircle (half of a great circle, or 180 [degrees]), we conclude that a pair of points on the rectangle separated by a distance d will be separated by an angular great circle distance
of at least (1/2)(d/D)180 [degrees] and no more than (4/[Pi])(d/D)180 [degrees] = d180 [degrees]/([Pi]R).
On April 2, Boeing broke both records, besting the Great Circle Distance
Without Landing record by flying from Boeing Field, Seattle, to Kuala Lumpur, Malaysia, covering 12,455.
Named "Lorikeet," the twinjet covered a great circle distance
of 3,891 miles (6,262 kilometers) with a non-stop flight from Hilo, Hawaii, to Noumea, in New Caledonia.
Ship brokers and charterers need voyage time and distance estimates to project costs, but simply using great circle distances
can give unrealistic or misleading predictions," said George Schlinkert, VP of Route Advisory Services at AWT.
