A drop in oil pressure combined with a rise in oil temperature is a critical condition that suggests significant potential issues with the engine. This combination typically indicates that the engine is not adequately lubricated, which can lead to increased friction and overheating. When oil pressure decreases, it suggests that the oil pump may not be functioning correctly or that there is a leak, while the rising temperature indicates that the engine is not being cooled effectively.

In aviation, oil acts as both a lubricant and a coolant for the engine. If the oil pressure falls below the acceptable level, it can result in insufficient lubrication to engine components, leading to accelerated wear or outright failure. The accompanying rise in oil temperature signifies that the engine components are becoming excessively hot, which can further exacerbate any existing problems.

Thus, this combination is a strong indication of imminent engine failure, and pilots are trained to respond promptly to these symptoms. Immediate action is critical to ensure safety, such as preparing for a safe landing or conducting an emergency procedure, rather than continuing to fly under these hazardous conditions.
