MAX is back, are you in?

NBC News
Boeing 737 Max completes first U.S. commercial flight almost 2 years
after worldwide grounding


American Airlines Flight 718 departed Miami International Airport at
around 10:30 a.m. Tuesday and landed at New York's LaGuardia Airport
at 1 p.m., slightly ahead of schedule.
The airline plans to fly the Max from Miami to New York and back
through Jan. 4 before adding more routes.


Don't plan on flying anytime soon, so I'm not affected.

Ditto....but when and if I do, and it's a Max, I would have no problem with that.

Yes, I'll fly in a Max. Every inch of that plane has been scrutinized. I'll be more worried about getting in a wreck on the way to the airport... whenever I fly again.

Sure. I mean what are the odds of another engineering failure? Gotta be at least three to one.

We'll take the house. Honey, the chances of another plane hitting this house are astronomical. It's been pre-disastered. We're going to be safe here.

If the tickets were cheaper, I’d totally fly it.

Banished or of his own volition? (I'd rather have a forum with max.)

Ask me in five years, if there have been no crashes.

Did they rebuild anything, including the way the engines are mounted? Or was it just reprogramming the computerized controls?

Additional sensors and training on how to override.

NO !
Inherently unstable aircraft patched with software.
And I am a pilot.

Nope. The MAX was originally designed to use the same engine as the
737-800 but then the Boeing geniuses decided to use the larger
intake LEAP engine to improve fuel efficiency.
That required a change in how & where the engines get mounted. banghead smiley

Just to clarify, the Max is not an inherently unstable aircraft. Rather it has a little less inherent stability than previous generations of 737. But that stability is still positive and within the limits of Federal Aviation Regulations (indeed it is illegal for airliners to have inherent instability).

However in order to maintain minimal training requirements for pilots of the Max (coming from previous versions of the 737), regulations required that it behaved like the former. Therefore Boeing had to add a system they call MCAS. MCAS has been implemented successfully on many other aircraft. The problem is this particular implementation on the Max was badly designed from a software and interface point of view.

Yup, but for what it’s worth, Boeing had to use the LEAP engines, their hand was forced by the Airbus A320neo. From a technical point of view, Boeing really needed a clean sheet design with this one.

Generational improvements in an airliner product family comes primarily from the engines. One of the biggest factors in improving engine efficiency is going to larger diameter fans with their inherently higher bypass ratios.

But the 737 is constrained by its short landing gear, which Boeing can't really lengthen due to the need of preserving compatibility with existing support and infrastructure equipment of its customers, and minimal pilot training requirements. Yet they did increase the nose gear a little on the Max to accommodate the LEAP engine. Still, the 737 can't take advantage of the most efficient LEAP engines with bigger fan diameters. The Airbus A320 family does not have this problem and have been able to take full advantage of the bigger better engines, thus giving them an edge in efficiency.

The Max will be the last version of the 737 ever.

No. And I usually fly >150K miles per year.
