Questions and Answers

What is the main effect of ice accumulation on a helicopter's rotor blades?

  • Increases performance and decreases weight
  • Modifies the blade shape, decreasing rotor performance (correct)
  • Causes minimal impact, not affecting flight performance
  • Decreases resistance and increases lift

    • How does ice accumulation impact a helicopter's rotor's weight?

  • Significantly increases the weight of the rotor blades (correct)
  • Decreases the weight due to the low density of ice
  • Depends on the thickness of the ice layer
  • Has no effect on the weight of the rotor blades

    • Which areas of an aircraft are affected by ice contamination according to the text?

  • Only the wings and landing gear
  • Mainly the engine intakes and windows
  • The areas where water droplets impact the aircraft (correct)
  • None of the above
