Final answer:
An LRU-16P life raft should inflate to its full shape and size within 25 to 30 seconds during a function test to ensure readiness in emergencies. Regular inspections and function tests are essential for maintaining its reliability.
Step-by-step explanation:
When testing the inflation time for an LRU-16P life raft, the raft should inflate to its designed shape and size within approximately 25 to 30 seconds after deployment. This rapid inflation is critical to ensure that in the event of an emergency, the life raft is ready for occupants as quickly as possible. It is important that regular inspections and function tests are performed on life-saving equipment like the LRU-16P life raft to check for any defects or potential issues that could compromise its performance in a real-world situation.
