MAX 9 will be a while yet as they have some new door failures to program in.

MAX's FMC and VNAV are bugged in real life, they should first fix it in real life before PMDG replicates it

Could you elaborate that a little further please?

I guess not many airlines care about issues, considering that there are nearly six thousand orders for the MAX.

That was a very interesting read. Boeing really seem to have lost their way nowadays. Even the NG pushed the 737 design too far imo, and now the MAX is taking the almost 60 year old design to another level again. But, I'm 99% sure we'll see the MAX in sim this year. Ifly seem to be in a pretty advanced stage with theirs and I'm sure PMDG is working hard on it behind the scenes too.

Yeah, a MAX would be great. Especially if they also simulated the multiple issues with the word not allowed thing and kept issuing recalls and groundings. If PMDG could pull that off...wow. As Real As It Gets to the max!

I don't know, I have my doubts about the accuracy of some of the things in this reddit post. Engine anti ice causing serious damage if left on? Why and how? All it's doing is supplying hot bleed air to the front of the engine nacelle. If it's OK to do that at +10 C in the initial climb, how could it cause damage at -40 C in the cruise? (Does someone have access to an FCOM to check this?) 

Somehow, this reddit post smells of sensationalism to me.

It's actually a known issue, reported here: https://www.seattletimes.com/business/boeing-aerospace/boeing-wants-faa-to-exempt-max-7-from-safety-rules-to-get-it-in-the-air/ (https://archive.is/f514F)

Quote

 

Little noticed, the Federal Aviation Administration in December published a Boeing request for an exemption from key safety standards on the 737 MAX 7 — the still-uncertified smallest member of Boeing’s newest jet family.

Since August, earlier models of the MAX currently flying passengers in the U.S. have had to limit use of the jet’s engine anti-ice system after Boeing discovered a defect in the system with potentially catastrophic consequences.

The flaw could cause the inlet at the front end of the pod surrounding the engine — known as a nacelle — to break and fall off.

I talked to Rob about this Anti-Ice issue, and since he's determined to model the MAX as close to real life as possible, he's going to add this issue in the plane.

However, since some inexperienced simmers may misuse the anti-ice feature in the sim, and may severely damage their engine inlet on the virtual MAX they purchased from PMDG, he has decided to cancel the MAX project for fear of liability from all the angry simmers who now have a damaged MAX.

Thanks a lot for pointing out this glaring issue...now we'll never get a PMDG MAX! 🤨

/sarcasm mode off.

Personally I find the "FMC crashes anytime it encounters a vector leg" to be a whole lot more unbelievable. Would be curious what @Stearmandriver has to say about that because I just cannot see that be an acceptable and widespread fleet issue without an immediate fix issued.

It’s not, based off what he says, it sounds like we fly for the same airline.
 

The MAX is a great plane. I enjoy flying it. It’s a dog up at high altitude but other than that it’s not bad at all.

that post from Reddit does have a bit of hyperbole in it though. I’ve never experienced the issues with VNAV “lagging.” Don’t know why he’s bothered that there’s a mode called “retard.”

It’s real. It’s in U14.1 fmc software.

Wow that's wild. Funny how often you hear when people are teaching Vatsim "You can't just delete the vectors legs" and yet here we are in real life.
