Abstract: An electric autobrake interlock system for an aircraft includes an autobrake power interlock mechanism that prevents inadvertent (uncommanded) application of brakes. The autobrake power interlock removes operating power from the brake actuators whenever the autobrake actuation data does not indicate a legitimate autobrake application condition. The interlock processing occurs in parallel with the autobrake command processing such that even if an inadvertent autobrake command is generated, the brake actuators will be enable to act upon the inadvertent autobrake command. In this regard, the brake actuators are unable to apply brakes automatically unless the following two actions happen concurrently: the operating power is provided to enable the electric brake actuators and autobrake actuation control is commanded in response to the legitimate autobrake application condition.

Abstract: A system and methods for an electric autobrake function suitable for use with an aircraft is disclosed. The system includes a single master autobrake channel configured to generate a master autobrake command and a plurality of slave autobrake channels configured to receive the autobrake master command. The methods receive autobrake command actuation data, compute a common autobrake master command based upon the autobrake command actuation data, and synchronize brake application by utilizing the common autobrake master command to actuate all brake actuators.
