777-200/300er
On the 777, autobrake application occurs just after main gear touchdown when
1. Both thrust levers are at idle, and
2. the wheels have spun up.
The only time this is different is with MAX AUTO, when Autobrake will limit the deceleration to Autobrake 4 until pitch angle is less than 1 degree, and then will increase braking to Autobrake Max.
