So tell me what is the EICAS message produced fir this warning ? Just looked up the FCOM and didn’t see this nonsense.
It does not pass the smell test to generate a mater warning for that, master warning are for significant things like overspeed, stall, fire. Not for flying around in a perfectly acceptable configuration.
How do you know it’s not flap overspeed ?
From Volume 2, section 15, Warning Systems, of the B777 FCOM for multiple airlines:
Landing Configuration Warning
The landing configuration warning system alerts the crew the landing gear is not
extended for landing. The EICAS warning message CONFIG GEAR is displayed
• the airplane is in flight, and
• any landing gear is not down and locked, and
• any of the following configurations exist;
• either thrust lever below a nominal glideslope thrust, and below 800
• FLAP lever in landing position
If the message is displayed because a thrust lever below a nominal glideslope
thrust at low radio altitudes, the message remains displayed until the Thrust levers
are advanced or landing gear is down and locked.
If the message is displayed because the FLAP lever is in landing position, the
message remains displayed until the landing gear is down and locked.
Additionally in the aurals table (same section) for a GEAR CONFIG message:
Aural: Siren (If caused by Thrust lever at idle, silence by pushing Master WARNING/CAUTION Reset switch)
Lights: Master WARNING lights (If caused by Thrust lever at idle, extinguish by pushing Master WARNING/CAUTION Reset switch)
