Weight is the force that pulls the plane down due to gravity. In order for the plane to get off the ground, the plane must overcome its weight throught the force of lift. The more mass the plane has the more lift it has to produce in order to get off the ground.

## Does your weight change on a plane?

You do weigh less when you’re higher up, but not by much (in Earth term). The force of gravity is F=G(m1xm2/r 2 ) where F is force, G is a constant, m1 and m2 are the masses of two objects and r is the distance between the centers of mass. … The distance between the moon and the earth varies, but we’ll use 375,000 km.

## Is there a weight limit for flying on an airplane?

There is no set weight limit for passengers on commercial flights in the U.S., but some airlines, most notably Southwest, require customers who cannot fit in one seat to book a second. … Call the airline you wish to fly and ask about passenger size regulations.

## Does weight affect aircraft range?

Variations in aircraft weight do not affect the glide angle provided that the correct airspeed is flown. Since it is the lift over drag (L/D) ratio that determines the gliding range, weight will not affect it. … The only effect weight has is to vary the time the aircraft will glide for.

## Why is weight important in flight?

Weight and balance have a direct effect on the stability and performance of the aircraft. If a plane is too heavy, it may never get off the ground. If it’s out of balance, it may be uncontrollable when it does take flight. … Maintaining proper weight and balance is an extremely important balancing act.

## Is gravity less on 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.

## How can I calculate weight?

Weight is a measure of the force of gravity pulling down on an object. It depends on the object’s mass and the acceleration due to gravity, which is 9.8 m/s2 on Earth. The formula for calculating weight is F = m × 9.8 m/s2, where F is the object’s weight in Newtons (N) and m is the object’s mass in kilograms.

## What size person can fit in an airplane seat?

About Seat Size

Advocacy group Flyer Rights has noted that the average width of airplane seats has been reduced from 18.5 inches to 17 inches. The average pitch (legroom) between seats has decreased from 35 inches to 31 inches, and in some aircraft, the pitch is as little as 28 inches.

## When should an aircraft be weighed?

When operating under FAR 135, an aircraft must be weighed every 36 calendar months to establish its current empty weight and center of gravity.

## Who is responsible for the correct weight and balance of every flight?

1-1] The pilot in command of the aircraft has the responsibility on every flight to know the maximum allowable weight of the aircraft and its CG limits.

## What causes an airplane to pitch nose down when power is reduced?

What causes an airplane (except a T tail) to pitch nose down when power is reduced and controls are not adjusted? The downwash on the elevators from the propeller slipstream is reduced and elevator effectiveness is reduced. An airplane has been loaded in such a manner that the CG is located aft CG limit.

## What’s the most dangerous part of flying?

Boeing research shows that takeoff and landing are statistically more dangerous than any other part of a flight. 49% of all fatal accidents happen during the final descent and landing phases of the average flight, while 14% of all fatal accidents happen during takeoff and initial climb.

## What is the weight of a plane?

The Boeing 737-800 is an example of an average sized airplane. It has a maximum takeoff weight of about 80,000 kg (175,000 lbs). This includes the weight of the plane, which is about 41,000 kg (90,000 lbs), and the weight of the fuel which is about 18,000 kg (40,000 lbs).
