Myth about Airplanes

Airplane travel may be commonplace these days,but myths and rumors abound about modern flight.
31. When the planes flies without an engine
if both engines fail, a plane can glide 6 nautical miles for every 5000 feet. So at 35,000 feet, a plane can glide about 42 miles without power. Its why most accidents happen landing or taking off.
32. How the pilot acts when hijacked
If the plane is being hijacked when the pilot lands they will leave the wing flaps up that slow the plane down, this is to signal the airport that there is something happening in the plane .
33. Gasoline used in airplanes is unsafe
International standard ASTM D4814 is used for both fuel production and engine TC/STC certification. Mogas has been an FAAapproved aviation fuel since the 1980s and has had an excellent safety record.
34. Higher octane is always better
Only if needed for antidetonation. Octane does not increase power. Higher octane is always more expensive, though.
35. Mogas cost too much and takes revenue away from airports
Airports selling mogas recoup revenue lost to selffuelers, help sport aviation and flight schools grow, and retain the same flowage fees as 100LL sales. They also make real reductions in lead emissions, a serious public relations issue for General Aviation
36. An emergency door on a plane is easy to open
Most doors on planes are plugtype door, which are essentially larger than the opening; it requires a few different movements for the plane door to open. Another thing that makes it even more of a challenge is the higher altitude; the higher a plane flies, the more pressure that contrasts the pressurization within a cabin, effectively keeping it shut. There are several factors that actually make a plane door very hard to open.
37. The recycled oxygen on a plane makes people sick
The plane air inside the cabin is actually thoroughly filtered as it gets recycled. What actually makes most people sick on flights is the things that they touch, and then touching their eyes or mouth with the same hands. Every surface on a plane is teeming with bacteria, so keep this in mind on your next flight.
38. Regarding lift the pressure change that allows a wing to fly
Actually, the change in air pressure is indeed caused by the curvature of the wing, but rather because it pulls some air up, reducing pressure, and forces the rest beneath, increasing pressure. The science stays the same, just the way the air pressure differences were created was wrong.
39. A gunshot/bullet on a plane will cause immediate depressurization
A bullet that gets fired through the plane s body will simply create a tiny hole and exit; the cabin s pressurization system will compensate for the miniscule amount of pressure lost. If a bullet were to hit a window while in flight, it becomes a bigger problem. The whole window would immediately be sucked out, and the large hole would really cause a more substantial loss in cabin pressure, resulting in unsecured items nearby being potentially sucked out. A bullet hitting the fuel line
40. THE SEAT BELT IS DANGEROUS
Many people in cars believe seat belts damage their chances of survival. This isn t the case. They re highly important for stopping broken bones and all the other injuries which come from a plane crash.Whilst the argument they hinder escapes is valid, unbuckling is a matter of pressing a button. The alternative to not having a seatbelt is flying out of your seat and smashing another passenger in the back of the head.
