What you don't know won't hurt you...

No. It’s not bold and blue and “the intended message is clearly conveyed.” Especially during non time critical periods, such as with reference to starting/stopping motors on the ground, or when giving a departure briefing (“if we lose a motor…”). Now if you’re referring to actions and callouts during an engine failure, standard industry and company lingo is “engine failure,” and all checklists and QRC/QRH items use the word “engine,” and for the sake of safety, standardization, and clarity/conciseness, those items ought to be read/said as written, since there is likely a time critical element. But at the gate giving a brief about losing a motor? No issue. There is no confusion about the use of that word and is therefore FCOM compliant, both in the intent/spirit and the literal verbiage of the FCOM.

Another option from Boeing…Brake temp gage and having some warning before the wheel well, which on a 737 is the main mechanical room, erupts into flame…Most 737 take-offs inside an hour of landing exceed the Airbus 300C limit…What you dont know wont hurt you or maybe….Nah, pilots dont need to know about MCAS
