Automatic takeoff thrust control system
Controlled by the FADEC, the ATTCS automatically provides engine thrust reserve (RSV) in an EFATO, go around, or windshear. It can be set on or off on the MCDU, although is on by default.
| white ATTCS | armed |
| green ATTCS | engaged |
| cyan thrust mode and RSV | activated |
Automattically commands RSV when
- ATTCS engaged (Green)
- TL in TOGA
and one of the following
- N1 difference > 15%
- OEI on take off
- OEI during GA
- Windshear detected
