Now consider the case where a crew has smoke in the cockpit scenario and must urgently dump and land.
As I understand it, there's nothing to stop them from (per the checklist) dumping all that centre-section fuel. BUT the real hazard is that those faulty pumps are then running helter-skelter at the high jettison rate and will be pumping all that centre-section fuel overboard. Anybody see the flaw in that for a good old run-of- the-mill "smoke, so dump fuel and land ASAP situation"????? Very hot dump-pump dry-running in empty CWT? Nor sure if the CWT dump-pumps would shut off before the wing-tank levels reached the preset stop-dump levels (at some later date). Somehow doubt it.
So the jettison action would probably have the jettison pumps "running on" [dry] in an empty CWT. Not good. Would the ensuing fiery accident be put down to a CWT explosion or the smoke in the cockpit emergency - I wonder?
Is this a realistic concern?
