Which phase of flight requires special attention to hydraulic systems for landing gear operation?

The landing phase of flight demands particular attention to hydraulic systems for landing gear operation due to the critical nature of the gear deployment and retraction processes. During landing, the aircraft transitions from a high-speed environment to a controlled touchdown, necessitating the reliable operation of the landing gear. The hydraulic systems are responsible for extending the gear before touchdown and retracting it after takeoff.

If the hydraulic system fails or experiences a malfunction during this phase, it can lead to catastrophic outcomes, including an inability to safely land the aircraft. Therefore, pilots closely monitor hydraulic pressure and system status to ensure the landing gear functions correctly. This phase is inherently more critical than takeoff, climbing, or descending since the successful landing is heavily contingent on the gear being properly deployed.
