Windmilling engine and the backup generator???
Hi,
Certain aircrafts (like B 777) are fitted with backup generators (BUG). If for certain raisons the engine is shutdown or flame-out, the IDG is no longer on-line. Does the BUG come on-line in such case and provide electric power?
-If we have all engines flame-out, can the BUGs provide electric standby power, or only the RAT will provide the standby power.
Thank you.
Best regards.
