Were there sea wars and air wars in World War 1?
Yes, airplanes fought in the air, and battleships, cruisers and submarines fought at sea and under it.
How airplanes can fly in air in spite of being heavier than air?
The air pressure under the wings is greater that the pressure over the wings creating lift.
How do airplanes protect people from decreased air pressure?
The interior of the cabin is pressurised.
Why do airplanes get faster at high altitude?
less oxegen levels and air pressure.
What is normal air pressure for an air brake system?
In an FMVSS121 compliant air brake system, cut out pressure is between 115 - 130 psi, with a cut-in pressure of no more than 25 psi below cut-out pressure. The 90 psi figure is what the brake chambers are regulated at, not the entire system.
Why do you not experience a drop in air pressure when you travel via airplanes even though airplanes travel at high altitudes?
It is because an aeroplane's cabin is pressurized, meaning that it is sealed off from the atmosphere. This prevents air escaping and keeps the pressure constant.
Can an airplane go to space?
No. Airplanes need air to fly. The wing shape when passing through the air, creates more pressure on the bottom of the wing than on the top creating lift. In space there is no air and so airplanes will not work.
Why does the bottom of a airplanes wing have high air pressure?
Because the air moving above the wing is of lower pressure than the bottom. This pressure differential is what creates lift. Check out Bernoulli's Principle for more information.
How airplane suspended in mid air?
Airplanes are NOT "suspended in mid air" - they move through the air and are supported by 'lift' derived from the differential air pressure above and below their wings.
How do airplanes fly when they are heavier than air?
The airpresureunder the wings is greaterthan the pressure over the wings creating lift.
Does airplanes sometimes stop in air?
NO, airplanes have to keep moving in the air.
How do airplanes stay in flight?
Planes stay in flight because of bernoulli's principle. When air passes over a airplanes wing. The air that goes on the top of the wing moves faster than the air the goes on the bottom. Thsi auses a low pressure system above the wing and a high pressure system beneath the wing. The high pressure below the wing pushes the airplane up allowing it to fly.
