What is a critical safety measure before landing with jumpers on board?

• A. Checking all equipment is secured and jumpers are ready
• B. Ensuring the pilot is aware of the landing protocol
• C. Confirming all jumpers have exited the aircraft
• D. Disarming student AADs as applicable

Answer: (D)

Disarming student Automatic Activation Devices (AADs) is a critical safety measure before landing with jumpers on board because AADs are designed to automatically deploy a parachute if the jumper fails to do so at a certain altitude during freefall. If the jumpers are still on the aircraft and the AADs are left armed, there is a risk that the devices could mistakenly activate due to changes in altitude or other factors associated with the landing process. This could lead to unnecessary parachute deployments while the jumpers are still aboard, resulting in a potentially dangerous situation. Therefore, ensuring that all student AADs are disarmed is crucial for maintaining safety during landing.

While securing equipment and ensuring jumpers are ready is also important for ensuring a safe jump, and keeping the pilot informed about landing protocols is necessary for flight safety, these are not specifically related to the risks posed by AADs that could affect the safety of the jumpers during the landing phase. Similarly, confirming that all jumpers have exited the aircraft pertains to post-jump safety different from the immediate risk posed by armed AADs while still in the aircraft.
