What are the three operational checks of the landing gear system?

The three operational checks of the landing gear system are critical for ensuring its proper functionality and safety during aircraft operations. The correct answer highlights the importance of assessing the landing gear operation itself, which involves verifying that the landing gear extends and retracts as designed.

The position indicator is another essential component, as it provides a visual indication to the crew about the current state of the landing gear. This check ensures that the crew has real-time information about whether the landing gear is down and locked, which is crucial for safe operations during landing.

Emergency systems are also a vital part of the checks. These systems are designed to ensure that the landing gear can still operate in the event of a primary system failure. This check includes verifying that emergency procedures are functional, providing redundancy in case the standard operation is compromised.

Each of these checks contributes to a comprehensive assessment of the landing gear system, working together to enhance safety and operational readiness.
