If ITT reads 820 before a ground start, should you proceed?

Explanation:
ITT shows how hot the engine core is; starting an engine when the ITT is above the safe pre-start limit risks serious damage. An ITT of 820°C before a ground start means the engine is still too hot to start, even if it’s on the ground. Engaging the starter at that temperature can cause turbine blade damage, compressor issues, or an overtemp event. Therefore you should not proceed; wait for cooling and recheck the ITT until it’s within the allowable range before attempting a start.
