True or False? You must roll your sleeve down when working around rotary wing aircraft for uniformity and protection.

The statement regarding rolling your sleeves down when working around rotary wing aircraft is true. The correct answer emphasizes that maintaining uniformity and enhancing safety is crucial, as rolled sleeves can pose a risk during ground operations where rotating parts of the aircraft could cause entanglement or injury.

Uniformity in appearance promotes professionalism and ensures that personnel can be easily identified in a high-stakes environment. Additionally, rolled sleeves could leave skin exposed, leading to potential injuries from the aircraft’s moving components. Overall, the emphasis is on safety and maintaining a professional appearance, making the assertion that sleeves must be rolled down appropriate.

In this context, the other responses would misrepresent the standard safety procedures related to personal protective measures in aviation environments. The practice is applicable not just during flight but consistently when personnel are in proximity to these aircraft.
