'stuck' rudder pedal during landing roll out; Boeing 737 MAX 8
It’s likely they slowed to an appropriate speed for using the tiller steering. No need to stay on the runway if the tiller is working and you are at a appropriate speed.
Aviation Herald is reporting that another United B38M suffered a runway excursion and main gear collapse at Houston today;

Just a coincidence or is there a common cause?

The Max does have cat3B capability. Customer option on the NG that I flew previously. Interesting the HGS with the same operator is not certified for cat3B so is either modes cleared or HGS stowed dependent on crew choice. Beware pprune disinformation. I have no idea what happened in this instance nor whether United have cat3B authorization but would be surprised if they didn’t. I am a current instructor on type.

Upthread it was mentioned that UAL only had nine planes with the HGS ?...If so I would think that the CAT would be restricted to what's allowed w/o it for commonality purposes across that fleet...B
Is it 1 new thing for HGS to be certified for Cat3b? It always used to be Cat3a, I’m pretty sure because it does not contribute to the the automatic rollout. It could be used to monitor rollout, but does it now provide Cat3b rollout steering guidance?
One strange HUD issue at my airline years ago. They required all approaches with the RVR below 4000 to be coupled if available unless the RVR was below 1200 in which case you were required to hand fly. Never made a lot of sense to me.
UAL doesn’t do Cat 3B on the 737. None of the NG’s have a HUD. A handful of the MAX’s do. It’s not approved for use and is being progressively removed from those aircraft.
Is HUD not approved for use by UAL or not approved for use on any MAX? I have been involved with 3 HUD cert programs (not Flight Dynamics now Rockwell Collins) and would like to learn more about this.

As I said before I am a current simulator instructor on the NG and Max. I am not authorized to say who I work for. For clarification the customer has the HGS on NG and Max on the LHS and it is sop to use it. Further complication with cat 3. NG authorized for cat3a with HGS. Max authorised for cat3b but no HGS allowed. This may be a regulator driven issue and I am not sure why. The Fail Operational autopilot has Rollout mode and the root cause of the above runway excursions may have something to do with that or not as I am just speculating.
