1. A process for restarting a turbomachine, the process comprising:
determining whether the turbomachine has been shutdown greater than a first predetermined duration;
in response to determining the turbomachine has been offline greater than the first predetermined duration, determining whether a wheelspace (WS) temperature is greater than a predetermined WS temperature threshold;
in response to the WS temperature being greater than the predetermined WS temperature threshold, determining whether a compressor discharge temperature (CTD) of the turbomachine is greater than a predetermined compressor temperature threshold;
in response to CTD being less than the predetermined compressor temperature threshold, determining whether a restart lockout is activated; and
in response to the restart lockout not being activated, allowing restart of the turbomachine.
