What is essential to ensure prior to leaving an aircraft unattended at the airport?

Securing the aircraft with chocks and locks is critical before leaving an aircraft unattended at the airport to prevent it from rolling or being tampered with. Chocks, which are typically wedges placed against the wheels, prevent unintentional movement, especially in the case of wind or uneven ground. Locks serve to deter unauthorized access, thereby protecting the aircraft from theft or vandalism.

This step is integral to safeguarding the aircraft and ensuring the safety of others at the airport. By maintaining the integrity of your aircraft while it is unattended, you mitigate risks that could lead to accidents or losses. It is a fundamental practice in aviation safety protocols, demonstrating responsibility and compliance with operational standards.
