David W. Wragg classifies air services as medium-haul being between 1,600–4,000 km; 900–2,200 nmi; short-haul as being shorter and long-haul as being longer. [11] David Crocker defines short-haul flights as shorter than 1,000 km (540 nmi), [ 12 ] : 208 and long-haul as the opposite.
One can also use the 1 in 60 rule to approximate distance from a VOR, by flying 90 degrees to a radial and timing how long it takes to fly 10 degrees (the limit of the course deviation indicator). The time in seconds divided by 10 is roughly equal to the time in minutes from the station, at the current ground speed .
The logarithmic term with weight ratios is replaced by the direct ratio between / = where is the energy per mass of the battery (e.g. 150-200 Wh/kg for Li-ion batteries), the total efficiency (typically 0.7-0.8 for batteries, motor, gearbox and propeller), / lift over drag (typically around 18), and the weight ratio / typically around 0.3.
[27]: 13 Due to atmospheric drag, the lowest altitude at which an object in a circular orbit can complete at least one full revolution without propulsion is approximately 150 km (93 miles), [28] whereas an object can maintain an elliptic orbit with perigee as low as about 90 km (56 miles) without propulsion.
In extremely clean air in Arctic or mountainous areas, the visibility can be up to 240 km (150 miles) where there are large markers such as mountains or high ridges. However, visibility is often reduced somewhat by air pollution and high humidity. Various weather stations report this as haze (dry) or mist (moist).
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.
“Fly 1,500 miles home with me to vote,” Kayla Iutzwig says in a TikTok video showing her packing a suitcase and heading to the airport. The 21-year-old lives in Los Angeles but is registered ...
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).
