How do you check the APU egt and rpm? Is there a analogue device (like the NG), or in the SYS page like the 787? Thanks
In contrast, the 737 MAX, although it uses almost exactly the same APU as the NG (still the [now Honeywell] 131-9(B), just with minor bugfixes), lacks the NG's EGT gauge:
According to an FAA document ,from Nov 2020 on the 737-800 and 737-8 (aka Max) differences, which was "Approved by the Aircraft Evaluation Division", the removal of the APU EGT gauge does not impact the procedures or flight characteristics and is categorized as level-A ("Self-Instruction").
