Final answer:
The minimum possible displayed Oil Temperature on EICAS varies and is determined by the manufacturer's specifications for the aircraft engine. EICAS systems are designed to provide accurate operational data and alert thresholds for safe aircraft operation.
Step-by-step explanation:
The question is regarding the reporting capability of the Engine Indicating and Crew Alerting System (EICAS) on aircraft and its impact on the display parameters for oil temperature. The EICAS system is an advanced system used in aviation to provide flight crew with engine and other aircraft system information, including temperatures, pressures, and system status. This technology has improved the level of detail and reliability of reporting operational data.
Unfortunately, without the specific data on the aircraft type or EICAS system being referenced, it is not possible to provide the exact minimum possible displayed Oil Temperature in degrees Celsius. However, it can generally be said that modern EICAS systems are designed to reflect the actual operating conditions as accurately as possible and will alert the crew if the temperature falls below or exceeds predefined limits.
Therefore, the minimum displayed oil temperature on an EICAS would be based on the manufacturer's specifications for the engine and aircraft type, which ensure safe operation under all circumstances.
