When performing Engine Running On-Loads (ERO), in what order will personnel line up for exit?

• A. Forward order
• B. Side-by-side order
• C. Reverse order
• D. Random order

Answer: (C)

When executing Engine Running On-Loads (ERO), personnel must line up in Reverse order to ensure a safe and orderly exit. This sequence is crucial because it allows the jumpers to exit the aircraft in the reverse of their seating arrangement, typically from the rear to the front. By doing so, this minimizes the possibility of crowding at the door and ensures that each jumper has sufficient space to exit without hindrance, which is especially critical when the engines are running.

Furthermore, this order helps maintain stability and reduces the risk of accidents or injuries during the exit process, as the personnel are less likely to obstruct one another. The Reverse order takes into account the dynamics of exiting a plane while the engines are operational, ensuring that safety protocols are strictly adhered to during such a high-risk maneuver. Other arrangements, such as lining up in Forward order or Side-by-side order, could lead to confusion and increase the risk of missteps or accidents during the exit.
