QRH and follow steps
Why do we switch the pack flow to low?
Save fuel
Can you get the IDG back after disconnecting it?
No- maintenance
How is IDG fuel circulated?
Some of the fuel from each engine goes through the HP fuel line
to
the IDG heat exchanger (where it absorbs the heat)
to

and then
back into the outer fuel tank
