Which component is not impacted by low pressure in the emergency hydraulic system?

The nosewheel steering actuator is designed to function independently of the emergency hydraulic system's pressure levels. In many aircraft systems, certain components are critical for safe operation during emergency situations and have alternative mechanisms or backup systems to ensure functionality even when the primary hydraulic system experiences low pressure.

In this case, the nosewheel steering actuator can still operate, relying on other means or systems to maintain control. This contrasts with components such as the main gear inboard doors, flaps, and landing gear, which typically rely more heavily on adequate hydraulic pressure to function properly. If the emergency hydraulic system is experiencing low pressure, those components are likely to be affected, potentially leading to operational issues during critical phases like landing or takeoff.

Understanding the design and operational independence of various aircraft components in relation to hydraulic pressure is crucial for assessing emergency scenarios effectively.
