Is There A Toilet On Light Aircraft?

Mon Feb 27, 2012 7:22 pm

I always had this question in mind: What do you do if you (or any of the passengers) want to use the toilet when flying a light aircraft? These airplanes look exactly like cars, but with one less feature. You can't pull over!

Go before you leave?

Some VLJs have chemical toilets, with padded lids and seatbelts so they can carry an extra person in a pinch.

Hello OD-BWH,

As a private pilot (for now!) I can assure you that light aircraft do not have a toilet. Once you get up to larger aircraft (such as a Cessna 421, Beech King Air, and Cessna jets as small as the Mustang, etc- there is a toilet/extra seat- it's got a cover/cushion/seatbelt, but little to no privacy- you just ask the others to look the other way if necessary! In smaller aircraft without such systems, you can buy products similar to this:

http://www.amazon.com/LJ-Little-John/dp/B000XT473O

Not the most dignified way to go, but it will get the job done. So when you're planning a long flight, you can advise passengers to use the head before you take off, and explain there's nothing (short of the product I mentioned above) if nature calls. In terms of pulling over, that's one of the benefits in flighting in a relatively populated country like the US- usually if it's an emergency you can find a place to get down quick that has a bathroom or a tree!

Hope this answers your question,

Don't know about Beech products, but the Cessna 340 through 441 have the optional belted toilet. There is a privacy curtain that will screen the toilet from all but the aftmost seat (if installed). They're not particularly useful and many owner/operators (including my folks) have the toilet removed to save weight.

My 172 is always equipped with a large water (Aquafina) bottle on cross-country flights

Can't a 172 be flown with a window open? I remember there being a published max speed for flight with a window open for some small plains.

I'm not sure about all 172's (there have been a lot of models!) but the 2005 172/T I fly can have the window open at any speed the aircraft can do. It's not really comfortable however- even going relatively slow, the window open is loud and I wouldn't try to dump any liquid out of it! Given the quality of parts as well (anyone that is familiar with the LSA Cessna 162 Skycatcher should know about the forward door latch!) the strain that it may cause on those low-dollar parts isn't something to be trusted. In the summer, I'll have the windows open on the ground on hot days, but in the air, the vents work well enough, especially when it's nice and cool up there.

Hmmmm...toilets that double as seats on a light plane. Convenient yes....but just hope that nobody on board ate Mexican food or baked beans the night before. Otherwise you better hope the aircraft has working oxygen masks or indeed the ability to fly with windows open!

If your you-know-what can reach the window in a C172 while you are seated, you are wasting your time as a pilot, you belong in movies!
Just because I stopped arguing, doesn't mean I think you are right. It just means I gave up!

Many 19-seat and smaller aircraft used by scheduled carriers also lack toilets/lavatories. Some examples below. They were optional in some cases, for example on the BAe Jetstream 31.

If memory correct, some of the Jetstream 31s operated by CP's regional partner in Ontario did not have lavatories and passengers were reminded to use the facilities in the airport before boarding.

In glider flight, dehydration is a serious issue, so one must drink lots of water on long flights.
Given that what must come in must go out, systems have been developed for both genders:

I believe that in some Pipers (I've been in a few Cherokees that had it) there's a funneled tube contraption that pulls out from under the instument panel. Should be pretty self-explanatory.

one of the more important details about learning to fly a single is that ATC cannot hear when you call from the "acoustic microphone"

Most economical I've seen is a plastic bottle and a funnel (pilot was female) on a delivery flight for a light aircraft. The other pilot was male and had too look out of the window, I assume.

In that case, I wonder who continues the instrument scan?

Yes, you can fly a 172 with the window open, but trust me, you do NOT want to use that as a lavatory or even a means of disposing of waste by method of pouring. The air currents actually cause it to come back in the airplane in the form of spraying all over inside the rear of the cabin.

I've never seen that on a Piper (not saying they don't have them), but I have seen a tube under the pilot and co-pilot seats on the King Air I flew.
