In the event of a red NORM BRAKES FAIL EICAS message, how can braking be achieved?

The red NORM BRAKES FAIL EICAS message indicates a system failure affecting the normal braking system. In such scenarios, the primary alternate method to achieve braking would be to use the PARK/EMER brake. This brake serves as a backup to the normal braking system, ensuring that the aircraft can still decelerate and stop safely in an emergency situation.

When activated, the PARK/EMER brake applies brakes to the wheels independently of the hydraulic braking system that may have failed. This is particularly crucial when normal braking methods are unavailable or inadequate, allowing the pilot to maintain control and safely manage the situation.

While reducing throttle, activating engine reversers, or using the manual brake lever may contribute to braking, these methods do not directly substitute the function of the PARK/EMER brake in scenarios specifically indicated by a NORM BRAKES FAIL message. Thus, relying on the PARK/EMER brake is the most reliable and effective measure in this critical situation.
