In aviation, the flight length or flight distance refers to the distance of a flight. Aircraft do not necessarily follow the great-circle distance , but may opt for a longer route due to weather, traffic, to utilise a jet stream , or to refuel.
Similarly, the two Air India flights from New Delhi to San Francisco, AI173 [31] and AI183, [32] fly an eastward ground distance of about 15,110 km (9,390 mi; 8,160 nmi) over the Pacific Ocean instead of a shorter westward great-circle route of about 13,300 km (8,300 mi; 7,200 nmi) over the Atlantic Ocean, to avoid prevailing westerly headwinds ...
The distance formula, distance = rate * time, is used by the DME receiver to calculate its distance from the DME ground station. The rate in the calculation is the velocity of the radio pulse, which is the speed of light (roughly 300,000,000 m/s or 186,000 mi/s ).
The Loganair Westray to Papa Westray route and its return flight make up the shortest flight distance for any scheduled air carrier service. The route is 2.8 km (1.7 miles), and travel time, including taxi, is usually less than two minutes.
Staples stopped accepting Air Miles cards in July of that year, and Sobeys and Safeway stores will begin phasing out acceptance of Air Miles after 10 August 2022. [ 20 ] [ 21 ] [ 22 ] On 10 March 2023, Air Miles' owner filed for bankruptcy in Canada, and Chapter 11 bankruptcy in the US, and entered in to purchase agreement with Bank of Montreal ...
A nautical mile is a unit of length used in air, marine, and space navigation, and for the definition of territorial waters. [2] [3] [4] Historically, it was defined as the meridian arc length corresponding to one minute ( 1 / 60 of a degree) of latitude at the equator, so that Earth's polar circumference is very near to 21,600 nautical miles (that is 60 minutes × 360 degrees).
If a pilot is flying a 120-mile leg and finds after 30 miles that he is two miles left of track, then he has flown 4° left of his intended track, i.e. 2 × 60/30. left of track. Changing the heading four degrees right will now bring him to parallel the intended track. At that point he still has 90 miles to his next waypoint.
The radar mile is a unit of time (in the same way that the light year is a unit of distance), equal to the time required for a radar pulse to travel a distance of two miles (one mile each way). Thus, the radar statute mile is 10.8 μs and the radar nautical mile is 12.4 μs.
