Final answer:
The query involves engine Exhaust Gas Temperature (EGT) limits during takeoff, which is crucial to prevent engine damage. While 244°C may be too low, 477°C is a likely EGT limit for a jet engine during takeoff, and similar to automobile engines, engines must avoid overheating to maintain efficiency and prevent failure.
Step-by-step explanation:
The question refers to the Exhaust Gas Temperature (EGT) limits for an aircraft engine during takeoff. EGT is a critical parameter for jet engines, as it indicates the temperature of the exhaust gases, and therefore gives a measure of the engine's thermal performance. The EGT must be within certain limits to prevent damage to the engine. Based on the options provided:
- 244°C may be too low for a jet engine EGT during takeoff.
- 477°C is more likely to be closer to an appropriate limit for EGT during takeoff. However, the exact limit can vary depending on the engine model and manufacturer specifications.
- Yes, just like automobile engines, jet engines are also limited by how hot they can operate without overheating. Overheating can lead to reduced efficiency or even engine failure.
