• Is there a speed limit for airplanes,and what are its consequences?

Driving a car on roads most streets specifies a speed limit. You cannot have really have suspended warnings like that in mid air.In aviation regulators specify speed limits for different situations.For instance while flying at above 10000 feet or less airplane are allowed a maximum speed of 25 knots or 288 mph. Most commercial flights fly much higher at about 38000 feet at the average speed is 575 mph. There is no speed limit imposed at this altitude although when an aircraft goes faster than 768 mph it breaks the sound barrier and creates a sonic boom. This will affect life below with abnormally loud sounds and sometimes the pressure waves created even cause creaks in glass.

• What happens if you don’t put your phones on airplane made on a flight ?

Many airplanes were built before electronic devices became mainstream. The electromagnetic waves from phones, tablets, electronic headsets, electronic watch e readers and other can potentially interfere with aircraft communication. You now that squeaky noise on an audio system when a mobile phone is nearby?.That’s what could happen if people leave devices on during a flight. Although it isn’t much of a safety concern,it could be annoying for pilots and air traffic controllers you surely don’t went to be interfering with one of the those people.

• How high do planes fly, and what happens if a plane flies too high?

There is limit to how high airplanes can fly, Most commercial planes can fly as high as 38000 feet. If a planes exceeds the height it was designed to fly at that could destroy the aircraft. Insufficient oxygen at that altitude could lead to engine failure. In 2004 a pinnacle airlines flight carrying two crew members crashed after flying up to 41000 feet.

• What happens if you open the door during a flight?

First of all it would take a LOT of strength to open an airplane door mid flight.This is because the air pressure inside a commercial planes while flying much higher than the pressure outside.The higher the altitude the more the difference in pressure.However if someone did manage to open the door the pressure would eject the people standing close to it. Sometimes it could even damage the airplane and it could begin to come apart

• What causes turbulence?Is it dangerous?

Turbulence is common while flying.It is usually caused by a change in airflow.Air turbulence can occur because of changes in wind speed,thunderstorms and flying over mountain ranges or tall buildings that distort the air overhead or even a combination of these factors. Usually turbulence is quite harmless very few turbulence related injuries have been reported and even fewer deaths. In fact an American research report claims that you are 26 times more likely to die on a rollercoaster than by airplane turbulence
