Aircraft Minimum Fuel Requirements

Commercial Flights

Per ICAO Annex 6, Part I, section 4.3.6 "Fuel Requirements," airplanes should calculate their required fuel quantity as follows (summary; see below for actual ICAO text):
  • Taxi fuel
  • Trip fuel (to reach intended destination)
  • Contingency fuel (higher of 5% of "trip fuel" or 5 minutes of holding flight)
  • Destination

Hadley Cells About Atmosphere

The atmosphere transports heat throughout the globe extremely well, but present-day atmospheric characteristics prevent heat from being carried directly from the equator to the poles. Currently, there are three distinct wind cells - Hadley Cells, Ferrel Cells, and Polar Cells - that divide the troposphere into regions of

Jet Blast

Jet blast !

Jet blast is the phenomenon of rapid air movement produced by the jet engines of aircraft, particularly on or before takeoff. A large jet-engined aircraft can produce winds of up to 100 knots (190 km/h; 120 mph) as far away as 60 metres (200 ft) behind it at 40%
