What caused the 737 Max to pitch up?

The 737 MAX’s larger CFM LEAP-1B engines are fitted farther forward and higher up than in previous models. The aerodynamic effect of its nacelles contributes to the aircraft’s tendency to pitch up at high angles of attack (AOA).

How did Boeing fix the max?

Last November, the Federal Aviation Administration cleared the fleet to fly again provided that Boeing and airlines updated the Max’s flight control software and rerouted some electrical wiring, among other changes.

Is 737 MAX inherently unstable?

Estimated reading time 4 minutes, seconds. A claim that the Boeing 737 Max remains inherently unstable — despite its problematic MCAS controls software having been rectified — has been dismissed as untrue by a senior Transport Canada official.

Is Boeing MAX safe now?

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.

Did Boeing know about the 737 Max?

Did Boeing know about Max problems before the crashes? There is evidence that it did. On Oct. 17, 2019, Boeing revealed text messages between two of the company’s top pilots sent in 2016, which indicated the company knew about problems with the MCAS system early on.

Is it safe to fly 737 Max?

What went wrong with the Boeing 737 MAX 8?

Due to the way the new engines were fitted to the 737 Max 8, it acquired a handling problem in which the nose could pitch up unexpectedly; if uncorrected, this pitch-up could induce a stall.

Why does MCAS force the nose of the 737 MAX down?

MCAS forces the nose of the 737 MAX down because, under some circumstances, the nose of the aircraft can pitch up and this may result in a stall.

Is the Boeing 737 MAX a sound plane?

The base design is sound with none of the stability quirks of T-tailed airliners like the BAC-111 or DC-9/MD-80/90. The problem with the 737 MAX was a flight control smoothing system, the Maneuvering Characteristic Augmentation Systems (MCAS), had an uncharacteristically sloppy design, making it outright dangerous.

Why was the Boeing 737re dropped?

At one point, “the wind was blowing toward a new airplane.” The 737, he said, was structurally old technology, “with a 707 nose on the same sized body. We could never come up with anything better than a 737 and bring it to life.” So, the engineer said, the 737RE was dropped.
