No parachute jumps will be made at exit altitudes when the air temperature is colder than what degree?

• A. -5 degrees F
• B. 0 degrees F
• C. -10 degrees F
• D. -15 degrees F

Answer: (C)

The correct temperature threshold for conducting parachute jumps is critical to ensuring the safety of jumpers, especially in cold conditions. -10 degrees Fahrenheit is the designated cutoff point because at this temperature, there are heightened risks associated with jumping, such as the potential for frostbite and hypothermia. These risks increase significantly as temperatures drop, making it more challenging for jumpers to maintain body heat and leading to impaired physical performance. This standard helps ensure that operations are carried out under conditions that minimize health risks to personnel, allowing for safer jumps and better overall mission success.

When temperatures fall below this threshold, training and operational guidelines dictate that jumps should be halted to protect the welfare of the crew involved. Therefore, the decision to set the limit at -10 degrees Fahrenheit aligns with these safety protocols to mitigate risks and ensure effective execution of parachuting activities.
