Final answer:
The duration of the offline period for ATIRCM system cannot be determined without more information. Two hypothetical scenarios are presented: one where the system is completely offline for the duration of its power up, and another where it operates at reduced capacity for 24 hours. The actual offline duration can only be determined by referring to technical details of the system.
Step-by-step explanation:
The question refers to the ATIRCM (Advanced Threat Infrared Countermeasures) system and the CMWS (Common Missile Warning System). ATIRCM powers up simultaneously with CMWS, but the specific duration of the offline period is not mentioned in the question. Without more information, it is not possible to provide an exact answer. However, if we assume that ATIRCM powers up immediately after the offline period ends, then the system will be offline for the duration it takes to power up.
Let's consider two scenarios:
- If the ATIRCM system takes 2 minutes to power up, then the system will be offline for about 2 minutes before it can start protecting the aircraft.
- If we assume that ATIRCM operates at half-power for 24 hours, then it implies that the system is not completely offline but working at reduced capacity during that time period. In this scenario, the system may still provide some level of protection to the aircraft, but it won't be fully operational.
It is important to note that these scenarios are hypothetical, and the actual duration of the offline period for ATIRCM can only be answered by referring to the specific technical details of the system.
