Final answer:
The F-2B life raft is designed to inflate to its proper shape within 1 to 2 minutes during functional testing, ensuring readiness in emergency situations.
Step-by-step explanation:
When conducting a functional test of an F-2B life raft, the expected inflation time for the raft to reach its designed shape is typically very prompt, usually within 1 to 2 minutes. This rapid inflation is critical for ensuring immediate availability in emergency situations. The exact time can vary based on specific equipment design, ambient temperature, and the condition of the inflation system. These rafts are equipped with CO2 canisters or similar rapid inflation systems to allow for this swift response. Regular functional testing is part of maintenance protocols to ensure the raft is in good working order and will perform as expected during an actual emergency.
