In the event of hydraulic failure, brakes can be operated using which emergency system?

Explanation:
When hydraulic brakes are unavailable, an emergency braking path is provided that uses compressed air. This pneumatic system operates independently of the hydraulic circuit, so it remains usable even if hydraulic pressure is lost. The air pressure drives the brake actuators, allowing the pilot to apply braking and decelerate the aircraft to a stop. This setup is chosen because air systems are a separate, reliable source of power that can be stored or generated independently, offering a workable fallback when hydraulics fail.
