Why does it take so long to build a plane?

Why does it take so long to build a plane?

Complexity comes in two forms: design complexity and systems complexity. An aircraft that has retractable gear or multiple fuel tanks takes longer to build because the systems are complex. More parts equal more time. A design can be complex even if its systems are simple; any aircraft with a tapered wing comes to mind.

Why are airplanes so slow?

“The main issue is fuel economy. Going faster eats more fuel per passenger-mile,” said Aeronautics and Astronautics professor Mark Drela. According to Drela, today’s airplane builders actually favor a smaller, lighter, and therefore slower aircraft that peaks its fuel efficiency at slower speeds.

Why don’t they make planes faster?

Airplanes don’t fly faster because it is not in their economic best interest. Flying faster means burning more fuel. This means ticket prices would go up. History has shown passengers rather spend more time in the air if it means lower airfares.

What is the speed of commercial airplane?

Most commercial aircraft typically fly at around 460-575 mph, or 740-930 km/h, according to Flight Deck Friend. But private jet speed can vary depending on a variety of factors, such as the weight onboard and the weather conditions.

Why can’t commercial planes fly faster?

Airplanes don’t fly faster because they burn more fuel at higher speeds, meaning that it isn’t economical. In addition, operating at higher speeds puts more stress on the engines as well as the airplane fuselage, which causes them to wear down faster.

Why is it quicker to fly west to east?

Jet streams are, at their most basic, high-altitude air currents caused by atmospheric heating and the inertia of the earth’s rotation—and they’re the reason why flights from west to east are faster than the same route traversed in the opposite direction.

How long does it take to build a commercial aircraft?

As one would suspect, wide-body aircraft generally take longer than narrow-body planes and regional jets. If you include supplier lead time into the equation (parts are sent to the assembly plants from all over the world), then it takes 9-12 months to build an aircraft.

Why can’t commercial airplanes fly faster?

How Slow Can a commercial plane fly?

Specified cruising speeds for commercial airliners today range between about 480 and 510 knots, compared to 525 knots for the Boeing 707, a mainstay of 1960s jet travel.

Are private jets faster than commercial jets?

Private jets often fly at the same speed as commercial jets, which on average, fly 547–575 mph when they reach cruising altitude. Smaller private jets and private aircraft, on the other hand, often have the capability of flying faster than commercial airplanes.

What was the speed of Commercial Airplanes in the 1960s?

Specified cruising speeds for commercial airliners today range between about 480 and 510 knots, compared to 525 knots for the Boeing 707, a mainstay of 1960s jet travel.

What are the major advances in aircraft design?

The major advances in aircraft design – today – are rooted in efficiency and safety. The goal of most airliners is to pack a metal tube with some stuff on it full of passengers, send it flying through the air, and landing safely with the same contents it took off with.

Why do airplanes take so long to develop?

They happen slower because building an airplane is a big project – and designing one is a huge project. Their development cycle is slow because the safety of millions of people directly rely on the airplanes to be safe. Even airline seats undergo a tremendous amount of testing, never mind critical flight systems.

What are the biggest challenges facing the aviation industry?

“The main issue is fuel economy,” says Aeronautics and Astronautics professor Mark Drela. “Going faster eats more fuel per passenger-mile. This is especially true with the newer ‘high-bypass’ jet engines with their large-diameter front fans.”
