At initiation of thrust lever movement from SHUT OFF to IDLE, ITT must be what or less for all ground starts?

Explanation:
During a ground start, the engine’s ITT must be 120C or less at the moment you move the thrust lever from SHUT OFF toward IDLE. This limit ensures light-off occurs within a safe temperature range and protects the starter and combustor from heat-related stress as the engine begins to spool up. If ITT is higher than 120C at initiation, you risk a hot start or overtemperature, which could lead to an aborted start or damage. The other values either permit too hot a start (140C, 160C) or are more restrictive than the published limit (100C) and aren’t the specified threshold for this procedure.
