So it appears that some controls for the Asobo 737 MAX 8 MCP are specific controls for the aircraft, even if they are universal functions (like altitude selection) - I was able to bind my usual controls for altitude selection increase/decrease to the following and it does work.

Boeing 737 Max.

Bravo Honeycomb cannot change the altitude in cockpit although it can change all other variables (i.e.Speed, etc). I can only change the altitude with the mouse hovering on the Alt button in the dash.

FREQUENCY OF ISSUE

How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
All the time.

REPRODUCTION STEPS

Bravo Honeycomb Quadrant is correctly map to SELECT ‘ALTITUDE’ BUG but does not respond to the INCR DECR selector that is mapped to MINUS and PLUS and cannot change the altitude.

Note that all the SELECT ‘HEADING’, ‘VSI’, ‘AIRSPEED’, ‘VOR’ BUGs are working with MINUS and PLUS selector.

The altitude can be change with the ‘mouse’ over the Alt button in the dash or with ‘keys’ of the KEYBOARD mapped to ALT SEL DECREASE and ALT SEL INCREASE.

YOUR SETTINGS

What peripherals are you using, if relevant: Honeycomb Bravo Quadrant
[PC Only] Are you using Developer Mode or have you made any changes to it? No.
[PC, MSFS 2020 Only] Are you using DX11 or DX12? DX12
[PC Only] What GPU (Graphics Card) do you use? RTX4090
[PC Only] What other relevant PC specs can you share? i9-14900K, RAM 64

Do you have the same issue if you follow the OP’s steps to reproduce it?

Provide extra information to complete the original description of the issue:
• After engaging the autopilot on the 737Max, the autopilot disconnects and the plane roll to the left and goes nose down . This has happened a few times now. Or after taking off an airport after engaging the autopilot, the plane fails to follow the route .
Thank you.

I don’t think this is related to the altitude hold value control binding.

• I have exactly the same issue. I am using the AXAIR MIAP Pro 24. Reference Altitude works perfectly for all other aircraft (that I have tried) except the 737 Max.

The issue has been resolved - please scroll back through the post to find the correct binding that will work.

(MSFS 2024) Honeycomb Bravo

737 max and 787 have aircraft specific altitude adjustment settings.
USE: Alt Sel Decrease and Alt Sel Increase are the two to bind. It’s WORK.

The posted fix is not correct it has nothing to do with the actual problem of the Bravo not working. All the other options work… vs, hdg, crs, ias. Its only the alt that does not work

The altitude keybind does work if you use the correct one - the standard one under the “Aircraft” controls category does not work for the Asobo 737 MAX whether you’re using a Honeycomb Bravo or a standard USB keyboard (or any other input device). You must use the ALT SEL INCREASE/DECREASE keybinds found under the “Specific” category of controls, as shown here:

Appreciate you taking the time to reply… YES, working now. Thanks.

While this solution fixes keyboard bindings, it does not apply to the Honeycomb Bravo throttle.

By default, the adjustment knob on the right of the Bravo sends the PLUS and MINUS commands to the item selected on the selector knob to the left of the Bravo.

In the case of the Altitude setting, it fires off the SELECT ALTITUDE BUG setting when ALT is chosen, and then PLUS/MINUS will adjust the bug. Same with SELECT HEADING BUG when HDG is selected, etc, etc.

The 737 Max does not appear to have a corresponding setting to SELECT ALTITUDE BUG, and you cannot simply change what commands the adjustment knob sends because that would break it for VS, HDG, CRS, and IAS, which all still rely on PLUS/MINUS. You also can’t just double map the new altitude increase/decrease command because they would just change your set altitude every time you changed anything else.

So for anyone looking for a solution to the altitude selector being broken for the 737 on the Bravo, this is not it.

Can confirm that this is still a bug with the Asobo 737 Max and the Honeycomb Bravo. This is the only plane in the default lineup which cannot have the altitude selected with a Honeycomb Bravo. Its lovely that some people can work around it, but this can be fixed and it should be fixed. This has NOT been solved.

DarthFinibilis above has the exact reason why…
