What are different factors that airplane engineers need to think about when it comes to building airplanes?

The primary factors to consider in aircraft structures are strength, weight, and reliability. These factors determine the requirements to be met by any material used to construct or repair the aircraft. Airframes must be strong and light in weight.

Why are airplanes longer than wider?

Stability: Long narrow wings give a plane or bird more stability. (It’s a bit like a tightrope walker who holds a long pole across their body as they walk along the rope – the extra ‘arm’ lengths help to balance the body by adding more mass to either side of it.)

Why are airplane aisles so narrow?

The number of passengers on the aircraft is dictated by the square feet allocated to each passenger seat (plus their luggage). Economy seats (with little to no leg room) take up very little space. So the airlines can fit a lot of passengers on the flight.

Why dont they make planes wider?

Answer: The structure around the window is heavier. If you look at airplanes designed as freighters, they do not have windows. This is done to reduce the weight and maintenance costs.

How much do aircraft designers make?

Aircraft Designers in America make an average salary of $89,139 per year or $43 per hour. The top 10 percent makes over $123,000 per year, while the bottom 10 percent under $64,000 per year.

Why do planes fly faster at higher altitudes?

The higher the better One of the central reasons behind aircraft altitude is that, as the air gets thinner with every foot climbed, planes can travel more easily and therefore move faster and burn less fuel, saving money.

How wide are airplane aisles?

According to the Federal Aviation Administration (FAA) Seat and Aisle Regulations, the width of airplane aisles ranges from 12 to 20 inches depending on the size of the plane and its passenger seating capacity.

Are Airplane Seats small?

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.

Are bigger planes safer than smaller planes?

Not necessarily. Basically speaking, it isn’t the size of the plane that makes it more or less safe. However, small planes are more affected by severe weather conditions, due to their lower weight and less powerful engines, which could pose a serious danger in the wrong circumstances.

Why are airplane cabins pressurized?

Why Pressurized Cabins Are Necessary. Cabins are pressurized to create a safe and comfortable environment for pilots, crew and passengers. Most commercial airplanes fly at around 30,000 to 40,000 feet above sea level. At high altitudes such as this, the air is thinner than it is on the ground.

What is the cabin pressure of a short haul plane?

Short haul aircraft can often withstand 100,000 cycles. Increased pressure would reduce the number of cycles an airframe could withstand.The airlines find that an 8000 foot cabin pressure is comfortable for passengers.A few aircraft maintain a 6000 foot cabin pressure to increase passenger comfort.

What happens if a window breaks on an airplane?

If a window breaks or emergency door opens, everything will be sucked out as the pressure attempts to equalize. The highly pressurized air inside the cabin will travel outside of the airplane where the pressure is much lower. Some people assume that only the cabin of an airplane is pressurized, but this isn’t necessarily true.

What is the highest cabin altitude allowed on a plane?

The highest cabin altitude that could be permitted is 15,000 ft, above which hypoxia-induced loss of consciousness can occur.
