C-130J Pilot MQF Practice Test

When a CREW DOOR OPEN or RAMP OPEN ACAWS message appears, the immediate action is to have the crew and passengers fasten their seat belts. The door or ramp being open presents a serious safety hazard—unsecured people and items can be whipped around by wind, turbulence, or abrupt aircraft motions, leading to injuries or loss of control if someone is not restrained. Securing everyone with seat belts maintains人员 safety while the crew can address the door status.

The other actions aren’t the first step because oxygen is only required if there’s depressurization or a high cabin altitude issue, which isn’t implied by this warning. Having the loadmaster investigate would put someone near the open door/ramp and create additional risk at that moment. Descending to below 10,000 feet isn’t the immediate response for this ACAWS message; the priority is securing personnel inside the aircraft.
