Hallo, I wonder about autobreakes.
I saw questions stated as below. Anyone who can say if alternative 2 for both questions below is correct or if another alternativ should be correct
Auto braking will operate:
1 at any engine power, provided aircraft weight is on the wheels
2 at any engine power, provided the anti- skid system is operative
3 only when the engine thrust levers are at IDLE
4 only when the engine thrust levers are in REVERSE
Next question
Provided the system ON and armed, when will an automatic brake system be activated after landing?
1 At touch down and throttles retarded
2 When spoilers deployed and throttles retarded
3 When the wheels are decelerated fast enough to initiate a skid
4 When spoilers deployed and brake pedals depressed
