Auto-Brake RTO disengage in A380
 
Hello,

I know that A380 has low, med, and hi/RTO auto-brakes. But is it possible to release the auto-brakes using any other buttons except the ones shown on the brake panel?

Don't know the A380, but on the A300 you could release the autobrake by pushing the brake pedals. I imagine the same logic would apply on the A380.

Generic, I Think
 
In most cases, 'tapping' the toe pedal will disengage any/all auto-brake functions on nearly all aircraft. No reason to think that the A380 is different. Is this airplane-related or F.S. - related. I know nothing about the game's behavior.

Same on the 744... tip the toe brakes, autobrakes disengage. No idea though how this works on the newer A3xx series.

1)Applying brake toe brake pressure disconnects autobrake.
2)Pushing the autobrake button disconnects autobrake.
3)Disarming the spoilers disconnects the autobrake.

I think thats how it was on the A340 when I think back. Guessing A380 not too far from that also.

A320 same as last post, the easiest is to cancel the spoilers.

also a/brake disconnect on the thrust levers.

From FCOM:

The basic AUTO BRK disarms or deactivates when:
‐ The flight crew applies sufficient pedal deflection on one or both brake pedals, or
‐ The aircraft is in flight for more than 10 s (for RTO mode only), or
‐ The flight crew sets the AUTO BRK Mode selector to DISARM, or
‐ The flight crew presses the RTO pb in order to turn off the RTO light, or
‐ The flight crew presses one of the A/THR instinctive disconnect pushbuttons (only with basic AUTO BRK LDG modes, not for RTO mode), or
‐ Any basic AUTO BRK arming condition is lost, or
‐ The ground spoilers retract.
