I know what the bernoulli effect is, and i have my essay written but it sucks, and i wanted to add more details so that is why those questions are the ones i asked below the topic description^_^

You might get more answers if you spelt Bernoulli properly

The Bernoulli effect states that a fluid (air in this case) will have less pressure as it travels faster. An airplane wing is curved on the top and flatter on the bottom (in most cases). This causes the wind caused by forward motion to travel faster over the top of the wing (because it has further to go in the same time) than on the bottom. The lower pressure on the top causes lift. This effect also occurs on the propeller which is shaped like 2 horizontally opposed wings.
There are different pilot's licenses. A sport pilot requires the least time (something like 20 hours of instruction), and as the complexity and privileges increase, so too does the time required to get the associated licenses. Each license requires a knowledge (written) test and a practical (flying) test. To become an airline pilot requires many prerequisites. A private license, a commercial license, and instrument license, a multi engine license, and the Airline Transport license. Each requiring many hours of training and tests. There are also endorsements for various aircraft that must also be achieved.
Flying on an airline is statistically safer than riding in a car, but small, single engine planes are more statistically akin to riding a motorcycle. For some info on plane crashes you can visit FAA.org
and the ntsb website.

I'll tell you all I know. It's usually not the impact that kills people in aircraft, it's the fire and smoke inhalation. People who want to become a private pilot, have to take groundschool for a couple of months and log about 150 hours. You have to write a written test and and fly a checkride. If you want to do commercial flying, you have to work your way up the licences, like commercial pilot's licence and stuff. Safety routines on commercial planes are the brace position, where you put your arms in front of your head on the seat in front of you and put your head down on that, the stewardess' backwards facing seat and of course seatbelts.

The Bernoulli Effect says when velocity increases, pressure decreases. An airplane wing is curved on top and flat on the bottom. So, the distance from the front of the wing to the rear of the wing is longer on top than it is on the bottom. As the wing goes thru the air, air on the top side has to go farther than the air on the bottom. So the air on the top is going faster than the air on the bottom. So the pressure on the top of the wing is less than the pressure on the bottom of the wing - The top of the wing pulls it up, the bottom of the wing pushes it up :-)
You can Google the other statistics you want.

Shoot....where was the internet when I was in school and was given those dreaded research/essay assignments?? If only.......
