Where should the JOC position himself/herself during an ERO after receiving a "thumbs up" from the crew chief?

• A. At the front of the aircraft
• B. At the midpoint of the wing just aft of the trailing edge
• C. Next to the jump door
• D. At the rear of the aircraft

Answer: (B)

The correct placement of the Jumpmaster (JM) during an Emergency Recovery Operation (ERO) after receiving a "thumbs up" from the crew chief is at the midpoint of the wing just aft of the trailing edge. This positioning allows the JM to maintain a clear line of sight to both the jump door and the aircraft's forward section, enabling effective communication and observation of jumpers as they exit. Being positioned here provides the Jumpmaster with an optimal vantage point to ensure that all jumpers are exiting safely and to facilitate any necessary adjustments or commands during the jump sequence.

The midpoint of the wing also helps the JM remain within the propwash and reduces the risk of interference with the aircrew's operations, while still being in a strategic location for both safety and functionality. This location enhances situational awareness, which is critical during the dynamics of an ERO where real-time decisions may be necessary.
