The speed to fly is the optimum speed through sinking or rising air mass to achieve either the furthest glide, or fastest average cross-country speed. [1] Most speed to fly setups use units of either airspeed in kilometers per hour (km/h) and climb rate in meters per second (m/s), or airspeed in knots (kn) and climb rate in feet per minute (ft ...
Within North America, the time needed to fly east across the continent can be decreased by about 30 minutes if an airplane can fly with the jet stream. [42] Across the Atlantic Ocean the North Atlantic Tracks service allows airlines and air traffic control to accommodate the jet stream for the benefit for airlines and other users. [43]
In November 2007, Skywest joined the then Virgin Blue's loyalty program Velocity Rewards (now called Velocity). Velocity Points can be earned on all Virgin Australia Regional flights, excluding charter flights. Points awarded vary from 0.5 per mile to one per mile, depending on fare class. [25]
For example, with the Alaska Airlines Mileage Plan, you can reach MVP status after flying 20,000 miles in one year, MVP Gold status after flying 40,000 miles, MVP Gold 75K status after flying ...
Subsonic aircraft must not fly faster than a specific percentage of the speed of sound. Usually passenger airliners do not fly faster than around 85% of speed of sound, or Mach 0.85. Supersonic aircraft, like the Concorde and military fighters, use the Machmeter as the main speed instrument with the exception of take-offs and landings.
The tailwind speed to fly will lie between minimum sink and best L/D. [14] In subsiding air, the polar curve is shifted lower according the airmass sink rate, and a new tangent line drawn. This will show the need to fly faster in subsiding air, which gives the subsiding air less time to lower the glider's altitude.
Flying within the U.S. will soon require an extra document that's more secure than a state-issued driver's license or ID if you don't want to lug around your passport with you.
North Atlantic Tracks for the westbound crossing of February 24, 2017, with the new reduced lateral separation minima (RLAT) Tracks shown in blue. The North Atlantic Tracks, officially titled the North Atlantic Organised Track System (NAT-OTS), are a structured set of transatlantic flight routes that stretch from eastern North America to western Europe across the Atlantic Ocean, within the ...
