Lies, Damn Lies, and Statistics

9 Oct

Japanese airliner All Nippon Airways (ANA) is asking all customers to help “lessen the load” by emptying their bladder before they get on the plane.  ANA is claiming that the additional weight in a full bladder is increasing unnecessary carbon costs, and would like everyone to do their part to help prevent this.

ANA is using some interesting math to support this recommendation:

“Based on an average human bladder capacity of 15oz, if 150 passengers relieved themselves on board an aircraft, this would amount to 63.7kg of waste. “

ANAApparently, I’m a geek – so seeing these stats got me racing to Google the info.

According to the intertubes, the average bladder holds anywhere from 300ml – 400ml (10oz – 13.5oz).  Granted that this is a pretty tough product to measure, and there are a few stats floating around, but they would generally put 15oz on the high end of what a bladder can hold.

My question is – who is waiting in a flight lounge with their bladder nearing capacity?  It’s not like you can race to your seat on the plane and then rush to the lav – you’ve got another 30 – 35 minutes before you’re going to be allowed the freedom to relieve yourself.

Unless they’ve exhausted every available option, I think choosing this message is an ineffective and superficial way for ANA to demonstrate that they are thinking about the environment.  But if they have managed to eliminate all extra weight, perhaps that’s the message they could share:

Here at ANA – we’ve squeezed every last ounce out of every flight – so now we’re asking you to, too!

    why stop there. Surely urine is the lighter of the body’s waste products?

    Alternate concept: Ticket sales might go up a bit if it becomes a clothing optional airline

    I just can’t stop seeing the logo as ANAL, and lightening the load by urinating does seem to fit that bill.
