What is the minimum allowable strength of a towline used for the aerotow of a glider with a certificated gross weight of 1040 pounds?

• A. 600 pounds
• B. 832 pounds
• C. 1000 pounds
• D. 1200 pounds

Answer: (B)

Towline strength in aerotow operations must be enough to safely handle peak loads during takeoff and any gusts. The minimum allowable strength is eighty percent of the glider’s certificated gross weight. For a glider weighing 1,040 pounds, eighty percent equals eight hundred thirty-two pounds. So, the minimum towline strength is eight hundred thirty-two pounds. A line weaker than that wouldn’t meet the safety margin, while a stronger line satisfies the requirement but isn’t the minimum.
