Galley / Lavatory Pitch Problems

Sun Mar 01, 2020 5:03 am

Hi fellow Anetters,

Had been browsing this site for many years and this is my first thread!

I am always very interested in creating my own LOPA for different aircraft, yet many dimensions are needed to get a doable LOPA.

The main issues are dimensions of galleys and lavatories, especially their pitch. Has anyone happened to know the actual pitch of these components? Cause you only get a rough estimation through those airport planning characteristics.

Taking this A35K LOPA as an example,
What is the typical pitch of the galley on door L4/R4, and the lavatories in the middle section (including the PRM-able one)?

Thanks a lot!

It really is quite variable, depending on what manufacturer the airline chooses. I am not sure the numbers are easily publicly available either...

Since the size of the cart is fixed, the size of galleys should be rather fixed as well as there's not much space for optimization.

The lavatories, though, can be "optimized” by introducing those slimline lavatories (as illustrated here), but since this is where they are doing ads I guess there should be some sort of figure available?
Also, I guess there might be guidelines on dimensions of PRM lavatories (not necessarily for regular ones), but I can't find relevant regulations.

Alright I’ll confess... what’s a LOPA?

Layout of Passenger Accommodation or Aircraft Interior Configuration Document.

The layout of all the furnishings in the cabin, including the seats and emergency equipment. Everything on there must also be physically present in the cabin, so cabin crew can use the quantities as a check of equipment as well.

Years ago in my youth , like in the 70s, I measured the width of a lav unit on a TWA 707, it was 32in. I've found over the years, using about 34 in for most LOPAs works out well, galleys similarly. When 34in pitch was "standard", it was normal to see a plane lose one row for a new lav or galley placement with no other seat changes.

also this from WaPo ,new lavs 24in only

It's not an easy topic at all. First of all, you need to review more detailed LOPAs, engineering ones, not just fancy sketches. Try to download the one good example by the following link: https://zakupki.gov.ru/223/purchase/pub ... d=57291669

Then, you need to realise that galleys, lavatories and other monuments are highly engineered products, designed to maximize efficient space utilization. Even though all the galley equipment, like trolley carts, containers (std units), ovens, beverage makers, are standardized, is does not mean that any galley is built to just to accommodate certain number of units.

Even though aircraft manufacturers tend to minimize a variety of galley units, numerous customization requests from different operators force the OEMs to be as much flexible as possible. Not to forget that some operators re-configure their aircraft via third-party completion centres. Hence, I dare to state that there's no common "the actual pitch of these components". Probably, the only rear galley modules (the aftmost in the cabin) are more or less standard dimension wise, yet they may be performed in endless variations to be fitted with different sets of equipment.

Thank you very much, this is exactly what I am looking for. How can I find more LOPA engineering documents, like this one?

As the information like this is very sensitive, it's not normally easily accessible for general public. One may only rely on some unintentional "leaks" like the one above. Try to look it up by fine-tuning and narrowing down your search keywords.

Odds are much higher for locating LOPAs for aircraft types that have been around for some time (Airbus 330, Boeing 777), than for relatively new Airbus 350.

Good luck!

P.S. Please follow the commonly accepted practices of quoting, don't overquote.

I have always wondered the same thing - the dimensions of lavs and galleys...

Thank you for posting this thread.
Never be proud. Always be grateful.

You are not alone! Make your own if you are not satisfied with the current ones!
You gotta know these figures to get more accurate results and more flexibilities on config.
