Is gravity the same in a plane?
You are correct that the force of gravity is slightly less the further you get from the earth. Airlines typically cruise around 30,000 – 35,000 feet. The force of gravity on Everest is about 0.434% less than the standard 9.8N/kg. This means that one pound at Sea Level would weigh about 0.995 lbs.
Is lift equal to gravity?
The opposing forces balance each other; lift equals gravity and thrust equals drag. Any inequality between thrust and drag, while maintaining straight and level flight, will result in acceleration and deceleration until the two forces become balanced. Gravity is the force pulling the plane down.
Can a plane fly without gravity?
Weightless Flight (also known as Parabolic Flight) is achieved aboard ZERO-G’s Boeing 727 aircraft named G-FORCE ONE. Weightlessness is achieved by flying G-FORCE ONE through a parabolic flight maneuver. Specially trained pilots fly these maneuvers between approximately 24,000 and 34,000 feet altitude.
Does 0g feel like falling?
Absence of gravity is known as weightlessness. It is like floating, the feeling you get when a roller coaster suddenly goes down. Astronauts on the International Space Station are in free fall all the time.
Can an airplane fly to space?
The bottom line is that airplanes can’t fly in space because there is no air in space. Airplanes rely on air to produce both lift and propulsion. Since there isn’t any air in space, airplanes must stay within the Earth’s atmosphere.
Can an airplane fly with one engine?
Yes it can. A twin-engine aircraft can fly perfectly well on only one engine. In fact, it can even continue the take-off and then safely land with just one engine. Losing an engine in flight is not usually a particularly serious problem and the pilots are given extensive training to deal with such a situation.
Can a jet plane fly in vacuum?
No, a plane cannot fly in a vacuum. In a vacuum, there’s no air mass in which the plane’s wings or aerodynamic surfaces can generate lift or apply leverage. Turbine or reciprocating engines also need air to burn fuel and to generate thrust or forward movement. Gravity will be the only force acting on the airplane.
Can a plane fall straight down?
Unless there is a catastrophic failure of an aircraft’s structure (which is extremely rare indeed), a plane cannot ‘just fall out of the sky’ any more than water can flow uphill. Even if the pilot let go of the controls altogether, the plane would eventually reach this straight-and-level equilibrium.
How high can a helicopter fly safely?
TLDR – Helicopters with turbine engines can reach altitudes of 25,000 feet during forward flight. However, helicopters cannot fly as high when hovering. The typical maximum height for a hovering helicopter is about 12,000.
Why can’t helicopters fly at high altitude?
Flying at such altitude is tricky because helicopters don’t operate as safely as fixed-wing airplanes in the lower-density air found higher up in the atmosphere.
What is the highest flight altitude?
45,000 feet
Can a helicopter fly across the Atlantic?
Two Ohioans made the first successful crossing of the Atlantic Ocean in a helicopter. The pair successfully flew across the Atlantic Ocean, landing in Prestwick Scotland. The flight covered 3,535 miles and took forty-two hours, twenty-five minutes to complete.
How long can a helicopter stay in the air?
approx two hours
Why do planes not fly directly over the Atlantic Ocean?
Ask the Captain: Why don’t planes fly in a ‘straight line?’ Answer: It is shorter to fly the Great Circle route than a straight line due to the circumference of the earth being so much greater at the equator than near the poles. Q: Captain, I often follow trans-Atlantic flights between Europe and the USA.
