I saw a video of an aeroplane in another subreddit where it literally jumps as if it went on a speed breaker. Why did the aeroplane react like that.
In: Physics
First you have to understand 2 things
– The surface of the earth is not flat
– Air is NOT uniform.
Depending on airflow, temperature and height of the ground in places the density of air will change, even localized conditions like tornadoes, cyclones and small storms will affect air pressure.
The thing is that airplane lift depends a lot on air currents and air pressure, a drop in air pressure could produce a drop in lift and cause the airplane to drop.
A good example of this is mountain ranges, over a small area there is a large change in air pressure due to the difference in terrain height between mountains and valleys.
Also an object that creates a large heat plum in a colder air area could cause a airflow that can push an aircraft upwards.
