What is the total number of demo equipment sets for an A321 aircraft?

For an A321 aircraft, the standard total number of demo equipment sets is four. These sets typically include various emergency equipment that is essential for training crew and ensuring safety procedures are properly taught. The equipment may cover life vests, oxygen masks, fire extinguishers, and other emergency tools necessary for safely managing in-flight emergencies.

Having four sets allows for adequate training opportunities, ensuring that all crew members can become familiar with the equipment they would use in emergency situations. This number facilitates comprehensive training sessions, accommodating larger training groups while ensuring everyone has hands-on experience with all types of emergency equipment. This approach reflects industry best practices in aviation safety and crew preparedness.
