Yes. A special fuel is made for planes.
Yes, you need a licence to fly an aircraft.
it depends what aircraft it is and how much fuel it can hold
Range - Max distance an aircraft can fly between take off and landing for the given amount of fuel . Endurance - Maximum time an aircraft can cruise for the given amount of fuel
It depends on the fuel capacity. Some airplanes can refuel during flight so conceivably, they can fly until the engines need maintenance. Current aircraft can fly up to 8,000 miles or about 14-15,000 kilometers.
Untill they run out of fuel. (it realy helps to know what aircraft your talking about)
It depends entirely on the type of aircraft and how it is flown.
To fly an aircraft you just need a student pilot CERTIFICATE. Everyone thinks that it's a license.
If the aircraft's engine thrust is reduced, by reducing the power the engines generate, less fuel will be burned. This said, over the course of a journey, there will be an optimum altitude and speed for an aircraft to fly at in order to burn the least fuel. This calculation will be the result of a number of things, including how heavy the aircraft is, and how the surrounding whether will affect it.
Yes, even for that size aircraft.
Jumbo jets have several fuel tanks. The majority of these fuel tanks are located in the wings of the aircraft. Some aircraft may also have auxiliary tanks in the tail or belly. The Douglas (now Boeing) MD11 has a fuel tank in the Elevator(horizontal tail surface) that is used to balance the aircraft to fly at altitude with less drag.
If this question relates to the fuel system , A gravity feed system would need to have the fuel tanks in the wings that would need to be above the level of the engines, IE: in a high wing aircraft. A pumped system would be used in a low wing aircraft or in a engine that required a constant fast fuel flow.
if you have every tried to fly a small, single engined aircraft around the world on 1 tank of fuel you would understand why the asnswer is yes
