Aeroplane doors should not be opened during flight. I think one of the reasons has to do with the stability of the aircraft. An aeroplane inside is isolated from the outside. There is no exchange of pressure between the outside and the inside. Pilots are able to control the aircraft using elevator, ailerons, rudder, spoilers etc. When you open the door, then another fact that need to be controlled is introduced in the equation - pressure difference. Unfortunately such kind of pressure difference together with high speeds and high altitudes makes it impossible for the pilots to control the aircraft anymore.

Will the speed of an aeroplane be same which is flying at different altitudes and have same mach number 2?
no mach no is defined as ratio of local speed of aeroplane to speed of sound. As the altitude increases the True speed of aeroplane increases and speed of sound decreases because of reduction of ambient temperature Hence the value of their ratio should increase at an increasing rate with increase in altitude. Keeping the Mach No constant say, 2 means reduction of speed to a large extent so as to maintain constant Mach No. Therefore same Mach no the aeroplane at higher altitude is flying slower
Is a DAB radio allowed in an airplane?
No, a DAB radio should not be used in an aeroplane. It can cause the aeroplane computer equipment to malfunction, however, a DAB radio is "allowed on" an aeroplane, but it will probably be checked to make sure it is not a bomb! :D
How many holes should you put on a paper aeroplane?

How do you become a aeroplane engineer?
You should study Aeronautical Engineering or Aerospace Engineering.
Should you french plait your hair for a long aeroplane ride?
Yes, definitely.
Should the damper be opened or close when operating the fireplace?
the flue should be opened
Why you should not inflate a life jacket inside the aeroplane?
Because it will make the flight attendants very annoyed if there isn't an emergency, and during an emergency it may make it difficult to maneuver in the airplane and get out of the exit.
How should you use the word low in a sentence?
If someone is being selfish or spiteful you would say: "you are being low." If something is low from the ground, e.g a roof, you would say: "That roof is low." or if an aeroplane were flying close to the ground you would say: "That areoplane is flying very low." I hope this helped, sorry if the examples were too confusing or rubbish.
Is the use of radioactive substances in hospitals safe?
It is only used when benefit outweighs risk. Comparable levels are found when flying in an aeroplane. Where radioactive therapy is used it can cause harm but this will be clearly discussed with the patient. Someone just visiting a hospital should not be worried about levels of radiation.
How much should a fire hydrant be opened?
A fire hydrant should be opened fully to ensure maximum water flow and pressure during firefighting operations. Opening it partially may restrict the flow and hinder firefighting efforts.
Why should you stay away from windows during a tornado?
Windows can break even in weak tornado, creating flying shards of glass. Windows also offer no protection from flying debris, which is the greatest danger in a tornado.
