RTO deceleration and activation conditions

FSS describes the RTO deceleration rate as equivalent to maximum manual braking. For a rejected takeoff, it lists engagement when wheel speed is above 60 kt, the thrust levers are at IDLE or REV, and the brake pedals are released. RTO selection by itself does not mean that braking has begun.

RTO status

Confirm the selected mode and armed state on EICAS. The selector position alone is not the whole system state.

RTO selector

FSS says the system modulates brake pressure to achieve the selected deceleration. Reverse thrust can therefore change the brake pressure required.

Disengagement conditions

FSS lists pedal braking, selecting OFF and advancing a thrust lever above idle during autobrake application. It also lists a brake-control-failure condition without defining its implementation. Use the displayed status and applicable checklist.

RTO activation

FSS lists wheelspeed above 60 knots, thrust levers at IDLE or REV, and brake pedals not pressed as conditions for RTO engagement. Selecting RTO alone does not satisfy these conditions.

A 9 November #general-talk post said the selector accepted RTO but would not select LO, MED or HI. FSS staff directed the user to report it in community support; no cause or fix was visible. Before landing, check the knob position and EICAS mode. If the selector will not move, do not assume a landing mode is armed. E-Jets #general-talk, 9 November 2026 ^[122]. ^[123]
