# How do planes keep balance?

## How do planes keep balance?

To maintain the proper balance, the center of gravity must be within the envelope and the airplane is loaded with passengers, cargo and fuel accordingly. In your case, it was necessary to move one person aft to move the center of gravity back and into the envelope.

Do planes perform better at higher altitudes?

But a common questions is, do airplanes fly faster at higher altitudes? Technically, no. As altitude increases, air density decreases, which decreases engine performance but gives it better fuel efficiency.

### Why do planes fly at high altitudes?

How high do planes actually fly? One reason that planes cruise above the clouds is so they can fly fast. The higher airplanes climb, the thinner the air gets, and the more efficiently they can fly because of less resistance in the atmosphere, according to Ryan Jorgenson, an aviation data analyst.

When flying at high altitudes What is the air?

Airplanes fly at very high altitudes of up to 30,000 to 45,000 feet. The cabin air pressure in an airplane is adjusted to compensate for these high altitudes. The oxygen level is comparable to levels found in elevations of 5,000 to 9,000 feet. Both men and women can get altitude sickness.

#### What happens if a plane is too heavy?

If the plane is too heavily loaded, then you will be unable to take off. (You might be able to get a meter or two above the ground due to a phenomenon called “ground effect”, but you could not climb any higher.)

Why do aircraft fly at 35000 feet?

A balance between operating costs and fuel efficiency is achieved somewhere around 35,000 feet, which is why commercial airplanes usually fly at that altitude. Most commercial airplanes cruise at an altitude of nearly 35,000 feet—around 6.62 miles (10,600 meters) in the air!

## What happens if an airplane flies too high?

If a passenger jet flies too high it reaches a point called ‘Coffin Corner’. At the altitude at which Coffin Corner occurs, the plane can’t speed up, slow down or climb; the only way to keep the aircraft flying safely is to reduce the altitude and go down.

Why is there low oxygen at high altitude?

As altitude increases, the amount of gas molecules in the air decreases—the air becomes less dense than air nearer to sea level. The human body reacts to high altitudes. Decreased air pressure means that less oxygen is available for breathing.

### How do you get more oxygen at high altitudes?

The only way to accomplish this is by breathing oxygen through medical devices (masks, Gamow bags, and tents) or homes with oxygen-controlled rooms like in some mountain homes in Colorado and other mountainous regions. Portable hyperbaric chambers are also used at high altitudes, especially during emergencies [2].

How does an airplane maintain its altitude and airspeed?

As long as you do not change power settings the aircraft will stay level. As fuel burns or people wander around the cockpit, weight and balance will slowly change and you may need to make minor trim adjustments.

#### What’s the best way to maintain altitude and speed?

Once the desired power setting is selected for cruise, leave it. Adjust attitude only to maintain your altitude. As the speed stabilizes you will find you will need to continually make very small adjustments to maintain level flight. Use trim to relieve control pressure until the aircraft flies level, hands off.

What should I do if I Find my altitude changing?

As long as you do not change power settings the aircraft will stay level. As fuel burns or people wander around the cockpit, weight and balance will slowly change and you may need to make minor trim adjustments. If you find your altitude changes you need to do two things.

## Why does the thrust of an airplane decrease with altitude?

At the left, we see that the thrust decreases with altitude. At the right, we observe that the TSFC actually decreases with altitude as well. However, I think this is counter-intuitive. I understand that F decreases with altitude, since density (and therefore mass flow rate) decreases when the airplane goes up.
