What are the rules concerning lavatory failures? How many per passenger have to be operational before the aircraft must divert?

AIRLINERS.NET CREW
DATABASE EDITOR

The procedures governing lav failures and Extended Toilet Ops are predicated upon the departure city.

For example, on a SEA-MEX route, a flight can venture further out to sea and fly a more direct route like the one on the left of this diagram:



But due to the potency of the local cuisine, the return trip from MEX to SEA must remain in range of acceptable diversion airfields, and must therefore adhere to the route on the right of the diagram.

What a nice, new way to think of ETOPS. I hear that some airlines currently at ETOPS 180 may try to get ETOPS 207, provided that they can supply PAX with enough Pepto-Bismol and Kaopectate per person. Generally it is 1.5 times the total seats on the airplane, but I'll ask my professor once I go to Air Transport today.

An AA 763 from ZRH to JFK diverted to YHZ last Friday due "lavatory problems". Following from Transport Canada incident summary.

AAL65, Boeing 767-300, enroute from Zurich (LSZH) to New York (KJFK), diverted to Halifax (CYHZ) due to lavatory problems. No emergency was declared and there was no other impact on operations.

In the Minimum Equipment List, we have charts to aid in making the decision before departure. It is just common sense, taking into account; flight length, number of passengers, time of day, route (yes route! some ethnicities pee more than others I guess) and the location of the inop lav.

During flight, it is more or less left up to crew discretion with the aid of SOC, (System Operations Control).

Considerations are maintenance facilities ... not just at a diversion point, but at the destination. If you were flying to a remote place, where maintenance facilities were not available, then it might be better to turn back!

I have only ever made a "lav diversion" once ... flying from YVR to YYZ, and all of the lavs become inop, and nothing we could do brought them back ... we landed in YYC.

Once flying a YYZ-TPA flight, we found the lavs inop due to a frozen water system. The aircraft originated that day in YQT and overnighted on a cold winter day. We let the passengers vote .. and they voted to continue as we were only about 1:20 from landing. Of course we made the obligatory "you can do Number 1, but not Number 2 PA!"

One of the scenarios in our simulator runs for ATC training is for a diversion due to lav issues, so you can be safe in the knowledge that we practice for such situations :-P
