DD,
We actually operate some B747 aircraft with anti-missile protection systems and chaff dispensers.
AFAIK, all of this equipment focuses on the engines and not the pack overflow.
Looking at schematics of the aircraft, I would also say that the outflow values are quite some distance behind the CWT.
Just my 2 halala worth.
