Original question:
“Why is pressure inside an aeroplane maintained at the normal ground level atmospheric pressure?”
It isn’t.
The reason passenger airplanes are pressurized is that humans need a certain amount of oxygen to stay alive.
The higher you go, the thinner the air and the less oxygen you take in with each breath.
A healthy human can stay comfortable at 8,000 feet altitude.
A typical commercial flight will travel at 30,000 feet.
Aircraft pressurization systems normally allow the pressure inside the cabin to drop as the plane climbs - until it reaches around 8,000 feet above which point air is pumped into the cabin to maintain pressure sufficient for human breathing.

hey
dude
here is your answer
Although aircraft cabins are pressurized, cabin air pressure at cruising altitude is lower than airpressure at sea level. At typical cruising altitudes in the range 11 000–12 200 m (36 000–40 000 feet), air pressure in the cabin is equivalent to the outside airpressure at 1800–2400 m (6000–8000 feet) above sea level.
hope this helps u
