Boeing Lounge Boeing 737 LRD

I mean, it wasn't that long ago that pilots did have to know things about the airplane, other than "the HI STAGE light means a bleed air is malefunkshun."

I understand a desire to not tell us things, as it can lead to troubleshooting/going down the wrong path/etc., but it would seem to me that both with MCAS and this, the pendulum was waaaaaay too far on the side of purposeful ignorance, to the point of hazard.

So I will say this, a CRJ or Airbus is much more of an aviation appliance than a 737. Given that the 737 doesn't have a modern EICAS, you DO actually have to know stuff about the airplane, we are definitely in agreement there.

Again, not memory items, if the cockpit fills up with an atomized oil smoke it might not be so simple. I also like to take my time, make sure you get the right one.

Agreed, not memory items, but there is more reasoning for the Engine Fire Switch than fumbling with a bleed switch.

Boeing wants the response to smoke or fumes in the flight deck to be the Engine Fire, Failure, Severe Damage checklist. Why? Because they want the associated Fire Switch pulled. Not just the bleed turned off.

Again, I’m not advocating for doing any procedure that is not published or authorized by either the manufacturer or operator. Follow your SOPs.

I bring this up simply as part of a good discussion that allows all of the 737 drivers here an opportunity to take a deeper dive into the various aircraft systems that might have been glossed over during training by various operators.

ALPA opposes Boeing’s latest 737 Max 7 and 10 exemption request

Opposition has arisen to a regulatory exemption Boeing has requested for the 737 Max 7's and Max 10's stall-management yaw damper (SMYD), while Boeing continues insisting its proposal poses no safety threat and that the SMYD is well proven.

Misspelling aside, it is an 'approved' answer on an ESV 'round here.

Pretty sure that SMYD is a sub menu in the maintenance function on the MFD. On the MAX9

ALPA Rejects Boeing’s 737 Max 7 and Max 10 Exemption Bid

On February 3, 2025, the Air Line Pilots Association, International (ALPA), the largest airline pilots’ union in the world, formally opposed a recent

More on this. I'm looking for the actual docket, but I can't find it. The Federal Register is abysmal, etc.

I just ferried an aircraft back to SEA with a new engine. The whole experience made me a firm believer in the process of when something lights up I'm basically "sYsTeM mAlFuNSHUN bAD" call maintenance guy. Then go get coffee. Things can get pretty wild if that process isn't followed.

Be careful messing around in that mx menu. We had guys pulling up the ECS page to look at pack temps and somehow they took out the CAT III placard on the PFD.

Rumor I heard was there was a line check going on and the check pilot looked up and realized it was not displayed but there wasn't any MEL stickers, oops.

The Boeing 737 Stall Warning System

The Boeing 737 Stall Warning System explained and illustrated

www.b737.org.uk

That system is fitted to the NG, and is not new. What evidently is new is the fact that Boeing themselves, having determined that a higher level of software assurance is required on the -7 and -10 and they're now requesting to be exempted from that. (Like I said, I can't find the actual docket just yet)

If you want to close the left bleed valve, why not pull the #1 Engine Fire Switch?

It will close the same valve and there are only 3 of those large rectangular handles within easy reach. IMO, that is easier muscle memory than trying to correctly identify one switch among many. Especially when you are possibly experiencing an adrenal dump and losing your fine motor skills.

Doing an irreversible action quickly in the smoke seems like a bad idea.

BOEING STOP BEING A SLEAZE!

If they spent as much time demonstrating improvement as they instead spend trying to cut-corners they would have close to $4 billion more in their pockets last quarter.

Flippin’ cultural wasteland.

“Granting this exemption will have no adverse impact on safety,” Boeing adds.”

Who believes this when Boeing says it?

 

[ctab5060X]

Is it irreversible?

Again, wasn’t trying to create a procedure, but rather a discussion.

Additional information I’ve have since found out from our technical team. On the MAX, the bleed valve is electronically activated and is also tied to the Engine Start Lever. i.e. taking the Engine Start Lever to Cutoff closes the associated bleed valve.

Another good reason to simply follow Boeing’s guidance and accomplish an Engine Fire, Failure, or Severe Damage checklist.

Sorry but neither the fire handle pull, nor fire extinguisher activating are irreversible.

You just push the handle back in and add fuel and it goes again. Nothing permanent about it.

Why are you “pretty sure?”


Let me guess, you’re one of “those people” who mess around with the MAINT menu, sticking your nose where it don’t belong.

Rumor I hear is we have enough idiots doing this that we are about to get a flight ops bulletin about it. It’s literally like some of ya’ll go to work looking for trouble.

Having helped out of station maintenance personnel access these pages I don’t see how being completely ignorant about them as an asset.

You do however and on top of that are attacking your coworkers over it?

I'm reading a book on the 727 development (having just finished one about the 757) and the way that they approached it all was "we're going to build a great airplane that not merely meets the customer's requirements but exceeds them" and, well, yeah.

FWIW, pilots accessing the Maint menu is verboten in writing at my shop.
