What two conditions trigger the amber OBOGS TEMP annunciator?

The amber OBOGS TEMP annunciator is designed to alert the crew when there are potential issues with the On-Board Oxygen Generation System (OBOGS). The correct answer identifies the specific temperature thresholds that activate this warning.

When the temperature of the OBOGS exceeds 200 degrees Fahrenheit, it indicates a potential malfunction or inefficiency in the oxygen generation system. At this elevated temperature, the system may not function correctly, potentially affecting the oxygen supply to the pilots. Therefore, temperature exceeding 200 F is a critical threshold that triggers the amber OBOGS TEMP annunciator.

The other choices highlight temperatures above 200 F, but only the response concerning 200 F correctly identifies the precise condition that activates this particular warning signal. The option referencing temperatures above 200 F and the maximum of 300 F would imply that both conditions are required rather than just signaling on the earliest temperature threshold. Understanding the significance of these temperature alerts is crucial for the safety and effectiveness of the oxygen delivery system in flight operations.
