Why is the Boeing 737 MAX unstable?

Barsky said this meant the 737 Max lacked sufficient ground clearance to accommodate its high-efficiency CFM International LEAP-1B engines. He said Boeing’s answer was to position the larger-diameter, high-bypass turbofans further forward and higher on the wing, which resulted in a tendency to pitch up.

Is the 737 Max aerodynamically unstable?

Yes, the 737 Max is stable in the conventional aerodynamic sense. 2. No, MCAS was not introduced only to make it handle like the previous 737 generation. Without MCAS, the 737 Max would not fulfil certification criteria related to stick forces at high angle of attack.

What is the difference between 737 and 737 Max?

The 737 Max can fly farther and carry more people than the previous generation of 737s, like the 737-800 and 737-900. It also has improved aerodynamics and a redesigned cabin interior and flies on bigger, more powerful and more efficient CFM LEAP engines.

Is the Boeing 737 MAX now safe?

Is it safe now? By endorsement of the FAA, Boeing and its pilots, the 737 MAX has been determined as safe to fly. But safe pilots fly planes safely and part of being a safe pilot is being well-trained and well-informed as to the full functionality of an aircraft’s systems.

Why are 737 MAX engines so far forward?

The larger engines required Boeing engineers to place them far ahead of the wing leading edge to achieve ground clearance. That design decision meant the 737 MAX would tend to pitch up while accelerating or when the aircraft experienced a high angle of attack – the angle between the wing and the direction of flight.

Can the 737 MAX be fixed?

Boeing Says F.A.A. Has Approved New Fix for 737 Max. But Boeing asked airlines last month to stop flying some of the planes because of a potential electrical problem.

Is the 737 Max quieter?

The quietest commercial aircraft in service today are likely the Airbus A220 and Embraer E2. These would be followed by the A320neo and 737MAX.

What makes the Boeing 737 MAX different from other planes?

The engines on the 737 Max aircraft are larger, and they are placed slightly higher and further forward to maintain ground clearance: While I haven’t found technical specifications on the matter, this likely moves the center of gravity forward by a few inches, other things being equal.

How many different types of Boeing 737 are there?

There are four different versions of the fourth generation of Boeing 737 aircraft. Boeing 737 MAX 7 – The next version of the 737-700. Boeing 737 MAX 8 – The next version of the 737-800 (the most popular 737). Boeing 737 MAX 9 – The next version of the 737-900.

What caused the Boeing 737 MAX to stall?

In short, they put them further forward and much higher on the wings. But the different mounting point made the Boeing 737 MAX prone to a stall. The engine positions on the wings forced the nose of the aircraft to go up. ▲CFM Leap-1B Engine on the MAX.

How has the Boeing 737 changed over the years?

The Boeing 737 has changed a great deal since its launch in 1968. The latest 737 MAX aircraft is a very different aircraft from the early Original and Classic series. As technology and airline expectations have changed, so has the 737 family, keeping it in the top spot for most successful narrowbody aircraft to date.
