"Whoever ... causes to be made unworkable or unusable ... any part ... used in connection with the operation of such aircraft, if such placing ... is likely to endanger the safety of any such aircraft"
The "part" is the PA system. While the device is playing the prank sound, it is temporarily "made unworkable" for its intended purpose of allowing the crew to communicate with the passangers. This "endangers the safety of the aircraft" because in certain situations it's possible the crew would need to communicate quickly with passangers or have silence so that they can understand each other and focus on solving an issue.
Edit: Looks like captain could override, flight attendants couldn't. That still causes a safety risk because in an emergency the cockpit might want to focus on flying the plane while the flight attendants instructed the passangers. Plus the distraction factor remains.
- Waterluvian 4y agoI don’t deny that it’s an important safety system. I’m curious, though, if they’re treated like safety critical systems in design or if emergency training covers how to act if the PA is down. I’ve got to believe it’s safety critical.
- shon 4y agoAgreed, safety critical, used in emergencies and non-emergencies for safety procedures.
- iudqnolq 4y agoI'd assume it's important to safety, but they have slightly less effective backups like yelling. I think the backup systems on aircraft are often things you'd rather not need to use.
- Waterluvian 4y agoI was thinking about yelling. I wonder if yelling on the larger planes is even viable. Especially in an emergency.
- LinuxBender 4y agoI suppose that would be a good hack to get the pilots to unlock the cockpit door.
