How much fuel do planes use?
they have larger engines, therfore it takes more fuel to provide the massive power that they need.
'Bush' planes are types of airplanes flown in the colder parts of the Northern Hemisphere, where there is easy access to fuel, mechanics, water landing areas and spare parts. In Antarctica, government logistical operations are carried out by military aircraft, because they can operate in the harsh and Spartan environment of the continent. 'Bush' planes are not suitable for use in Antarctica.
The Jet-stream certainly does. Planes can use the jet-stream to reduce the amount of fuel it takes to travel from one side of the planet to the other. This is because - so long as the jet-stream is flowing in the same direction the plane wants to travel - it can 'push' the plane forward, which uses less fuel.
