Why shouldn't the T-11 ATPS be jumped from a UH-60A?

The correct choice indicates that the T-11 ATPS should not be jumped from a UH-60A because it is not advisable to jump above 1250 feet AGL due to its drift characteristics. The T-11 parachute is designed with specific performance parameters, and jumping from a helicopter at excessive altitudes can lead to unpredictable drift. As the parachute descends, environmental factors like wind can cause significant deviations from the intended landing zone, potentially complicating recovery efforts and putting jumpers at risk of landing far from the target area.

Understanding the parachute's drift characteristics is crucial for ensuring safety and operational effectiveness, especially in military operations or during training. If jumpers were to exit the helicopter from a higher altitude than recommended, it could lead to potential complications, including difficulties in navigational accuracy and increased landing zone overshoot.

Options that mention other factors, like malfunction rates at higher altitudes, suitability for quick exits, or injury risks below certain altitudes, do not address the critical nature of drift characteristics and their impact on mission success. Proper training and adherence to altitude limits contribute to jump safety and mission effectiveness.
