When does the OBOGS TEMP light illuminate?

The OBOGS TEMP light illuminates when the bleed air temperature exceeds 200 F. This indication is crucial for the pilot as it alerts them to potential overheating of the On-Board Oxygen Generating System, which can compromise the effectiveness of the oxygen delivery to the pilot during flight. In general operational procedures, monitoring criteria like temperature helps ensure the safety and reliability of oxygen systems, particularly in high-performance aircraft such as the T-6.

When the temperature threshold of 200 F is reached, the pilot is signaled to take appropriate action to manage the system effectively and mitigate risks associated with high temperatures. This alert mechanism is an essential feature of the aircraft's safety protocols, ensuring that pilots can respond proactively to prevent hazardous conditions.
