What should be done before leaving an aircraft unattended?

Before leaving an aircraft unattended, it is crucial to chock the aircraft and cover it if it will be unattended for more than five minutes. Chocking the aircraft helps prevent it from rolling or moving unexpectedly, securing it in place and ensuring the safety of the aircraft and its surroundings. Additionally, covering the aircraft protects it from environmental factors such as dust, rain, or sun exposure, which can lead to damage over time.

This practice is particularly important in aviation safety protocols, as it minimizes risks associated with an unattended aircraft. The combination of using chocks and providing covers reflects a commitment to maintaining the aircraft's integrity and safety standards when it is not being actively monitored.
