Why maintain safe distances from propellers and intakes around high-performance aircraft?

• A. It helps reduce risk of injury from moving parts.
• B. It increases engine power.
• C. It helps reduce air resistance.
• D. Reduces risk of injury from moving parts.

Answer: (D)

The main idea is safety around moving machinery. Propellers and engine intakes operate at very high speeds and can cause severe injury or death if you’re too close. Staying at a safe distance reduces your exposure to those hazards—being struck by a blade or being pulled into an intake by suction or strong jet wash. Keeping space also gives you and the crew time to react if something unexpected happens and makes you more visible to the pilot. Other ideas like engine power or air resistance don’t address the immediate danger to people present near the moving parts, so they don’t explain why distance is important.
