What is the maximum packing time for a parachute constructed of natural fiber for emergency use?

  1. 30 days

  2. 60 days

  3. 90 days

  4. 120 days

The correct answer is: 60 days

The correct answer indicates that the maximum packing time for a parachute constructed of natural fiber for emergency use is 60 days. This time frame is important to ensure the reliability and effectiveness of the parachute. Natural fiber parachutes, which may include materials such as silk or other organic fibers, degrade more quickly than synthetic alternatives due to factors like moisture, UV exposure, and environmental conditions. This packing time is established to ensure that the parachute remains in a suitable condition for deployment when needed. In the case of natural fibers, regular inspections and re-packing within this 60-day limit are crucial to maintain the parachute's performance and safety. Adhering to this time frame can help aviators avoid malfunctions during critical situations, thereby ensuring the parachute can function as intended during an emergency.
