conehead Posted December 22, 2016 Share Posted December 22, 2016 Hmmm... I'm tempted to call bullshit on this one. I'm quite familiar with the operation and maintenance of waste systems on airliners, and there is no way to dump waste in flight. One could install such a system though... now that would be interesting! Link to comment Share on other sites More sharing options...

Would the cost of developing such a system save enough fuel to be worth it? Please note the restraint I am demonstrating by not adding one of the 18 jokes that readily spring to mind.

boestar Posted December 22, 2016 Share Posted December 22, 2016 The problem is the 6 inch hole you are putting in the aircraft if you were to do this. Thats a pretty big hit on the pressurization. Besides the fact that the systems are engineered specifically to PREVENT fluid loss in flight. "Blue Ice" is an extreme hazard both to the aircraft itself and the people on the ground.

boestar Posted December 22, 2016 Share Posted December 22, 2016 For the tank to leak in flight there are 2 distinct failures that have to occur, The internal "Dump"valve would have to overcome its pressure to allow the fluid to be released and the Outer Safety valve would have to be open. For that valve to be open, the exterior panel on the fuselage would have to be open as well. I am not say ing that cannot happen as I have had frozen lav panels in the past but it is very unlikely Link to comment Share on other sites More sharing options...

DEFCON Posted December 23, 2016 Share Posted December 23, 2016 The dumping of human waste from modified transport trucks as they move along our highways is a seemingly common practice amongst broker owner drivers of Indian descent, so why not aircraft too?

DEFCON Posted December 24, 2016 Share Posted December 24, 2016 Seeker I can't name my source, but if you'd like to investigate, begin your enquiry with mechanics that works on big rigs. If you really want to check, attend a truck stop and look at the center rear axle areas for evidence of discharge. Focus on brokers that travel with their family Link to comment Share on other sites More sharing options...

Moon The Loon Posted December 25, 2016 Share Posted December 25, 2016 Trains do it regularly. I don't thing airplanes do,do. But with airplanes, if they could/do, waddabout that long brown stain??? Link to comment Share on other sites More sharing options...
boestar Posted December 25, 2016 Share Posted December 25, 2016 I have spent enough times working on the crappers on aircraft that I could recite you the AMM verbatim. Well at least I could years ago. Seniority took that away from me (thank God) Link to comment Share on other sites More sharing options...
