The passengers travelling in an airplane must be well aware of all the precautions. Though, many passengers don't take the instructions given by the flight attendants seriously. There are certain safety precautions that should be kept in mind during taking off and landing.
I've compiled such precautions, have a look!
This is because when the plane takes off, the plane works against the gravity. You can't take the risk as the gate may open while you're in a washroom.
...so during taking off and landing, your balance may get disrupt and you may hurt yourself.
...so there is a risk that you may catch fire.
...taking off and landing as the body won't be able to bear the jerks of the aeroplane.
Let them serve hot drinks as they're used to it. You don't even try.
...in the storage bean as it can be risky for other passengers as it doesn't have sufficient space.
