Which type of rope is preferred for tying down an aircraft on the ramp?

Nylon or Dacron is preferred for tying down an aircraft on the ramp due to its strength, durability, and resistance to environmental factors such as UV rays. These materials exhibit low stretch under load, which helps maintain tension on the aircraft and reduces the risk of it shifting or becoming loose during windy conditions. Additionally, both nylon and Dacron have excellent resistance to rot and mildew, common concerns in outdoor environments where aircraft are parked, making them reliable over time.

Polyester, while a strong material, does not have the same level of stretch control as nylon and may not hold tension as effectively. Cotton, while a natural fiber, is less durable and can deteriorate more quickly when exposed to moisture and sunlight. Hemp, although strong, is less commonly used in modern applications due to its susceptibility to rot and the better alternatives available in synthetic fibers. Thus, nylon or Dacron stands out as the best choice for secure and safe aircraft tie-downs.
