When I was travelling with my 3 year old son in an aeroplane , I made my efforts to tell him how does an aeroplane fly ?
Where are the engines located ?

I also showed him the radar.
Then I showed him the aviation fuel tanker near the aeroplane.
To my surprise he asks me “Is it the same fuel that we get at petrol pumps ? If not then why a separate fuel for aeroplane ?

Kids questions can be endless but also very surprising at times !

There are two main grades of Turbine fuel :
Jet A-1 and Jet A
Both are kerosene type fuels.

Jet A-1 has a flash point of 49°C (120°F) and a freeze point maximum of -47°C. It is kerosene based high quality fuel that includes an anti freeze to prevent ice build up inside fuel tanks.

Jet A is produced and only available in the U.S. It has a flash point same as Jet A-1, but a higher maximum freeze point of -40°C.

Disadvantages of using normal fuel in comparison to aviation fuel :
1.Greater losses due to evaporation at high altitudes.
2.Chances of ice build up inside fuel tanks.
3.Greater risk of fire during handling on the ground.
4.Crashes of planes fuelled with wide cut fuel were less survivable.
5.Since space is at a premium on most aircraft, the amount of energy contained in a given quantity of fuel is important.

WINGS contain lined containers specially designed to store fuel.These normally run along the width of the wing.
