IIRC, the TCMA is fitted to ALL 787s regardless of fitted power plant..
Hope the descriptions below help.
TCMA (B787)Thrust Control Malfunction Accommodation
Thrust Control Malfunction Accommodation is an EEC function that provides protection against idle thrust asymmetry conditions while on the ground.
The EEC commands shutdown of the affected engine when the:
- airplane is on the ground, and
- thrust lever is at idle, and
- engine is above idle speed and not decelerating normally
The EICAS caution message ENG FAIL (L or R) is displayed with an aural beeper once the engine falls below idle speed.
