When engaging alternate brakes, which other system might need to be monitored?

Engaging the alternate brakes on a C-17 involves using a different braking mechanism than the primary braking system. This situation can impact the functionality of the anti-skid system, which is designed to prevent wheel lock-up during braking and maintain maximum stopping control. When alternate brakes are utilized, it is crucial to ensure that the anti-skid system remains operational, as relying solely on alternate brakes without the anti-skid function may lead to challenges in achieving effective braking performance.

Monitoring the anti-skid system is essential because if this system is inactive or has malfunctioned, the alternate brakes could lead to wheel skidding or loss of control, particularly during landing or when performing a stop on wet or slippery surfaces. Being aware of the status of the anti-skid system allows pilots to adjust their braking technique accordingly to ensure safe aircraft operation.
