Just curious about this one. Most of us know that the seat "pitch" is the measurement between the back of one seat to the back of the next seat, front or back. Now, for the first class suite seats that are aranged in the "herringbone" patern, does anybody know what the actual pitch of these seats is? I know the length of these seats are in the 70"-80" range, but they are also offset.

Yea, that's the bummer. I'm trying to figure out the "actual" pitch so I can "play" with some of my own configurations that would be on the 747 upper decks. I made some "guestamites" but I was hoping for something a little more accurate, if you will.

Most F-class seats are placed angled these days so pitch in flight direction is different. "Traditional" flat beds used to be 80 inch. Todays, including the privacy shells, 85+ inch. Airlines usually take the 95% percent lenght of the first class passengers (relative many (long) white males). The longest 2.5% have a problem when they fully stretch, the shortest a problem with the seat cushion lenght/ placing feet on the ground while seated.

Quoting Keesje (Reply 3): The longest 2.5% have a problem when they fully stretch, the shortest a problem with the seat cushion lenght/ placing feet on the ground while seated.
exactly. this is why i never was a fan of the BA or QF first or BA biz beds because when i lie flat, they were still too short...only VS has a bed on which i can fully extend, thus sleep comfortably.
though i too have wondered what the "true" pitch of those seats would be if you measured from one seatback to the back of the next seat. i dare say it is in the range of 40" for an herringbone layout like VS because the seats are approx 22" wide, plus the angle of the seats, and divider panels.

That sounds really cool, maybe you could post a little more information about what you are doing and or share some of it with the rest of us. I especially have always been interested in seat maps and airline configurations so it sound really cool.
Look for the part about their inflight service, and there is a flash presentation about their new Boeing 747-400 with the Dreamliner livery.
The presentation talks about the Boeing signature interior on the 747-400, and at the end of the presentation there are some seatmaps of the plane. An on the main deck, there is a legend that states the pitch in the new Herringbone first class is 47".
However, since right now as I write this post the China airlines website is not working, so I can't post the link to the specific part...
In addition, this 47" figure is just for reference..... the actual one depends on the actual configuration. For example, the actual pitch on the VS upper class suites is less on the A340 (and the 747-upper deck) than on the Main deck 747-400. This is because the seats on the A340 is tilted at an angle larger than on the 747-400 main deck (since 3 abrest on the A340 gives a larger available width than 4 abrest 747)..
I did some very crude calculations using AutoCAD, and it seems that the actual Upperclass suite pitch on the A340 is around 36", and the one on the 747-400 main deck is around 42". So do anyone here know what are the actual figures ?
On Air France 777-300ER first class, the actual pitch is very large- according to the Air France website, its 79", and I do believe that its true, because the airfrance first class doesn't make much use of the "overlapping" space that is possible with herring bone configurations... so its rather space inefficient.
On BA first class, the pitch is varying. This is because in the middle seats, there is not much "overlapping", and the pitch is basically the same as the bed length, i.e. close to 78". For the window seats, the pitch is smaller but still not constant due to the special shape of the 747 nose. I would guess around 50".

Great, great input sir. Thank you. I kinda got an idea of what the pitch would be buy "guesstimating". I'd try to do this buy going to Boeing's website, using some of the seat map examples under the detailed information link. Add up the total seat "pitches", then divide by number of "herringbone suites" and presto.
I'm just playing around with a fantasy fleet and how I'd confugure them. This post was to figure how I'd plan out a 747 Advanced. After playing around with it, I'd have 19 Suite seats on the upper deck with the herringbone pattern. 79 Business Class with 48" pitch similar to this Lufthansa configuration. And 320 economy passengers with a 33"-34" pitch using these innovative economy seats using the comfort configuration. Grand total of 418 passengers.
Anyway, that's what I'm playing around with. I've got some tallies of other Boeing and Embraer aircraft as well.
Name of my airline you ask? TWA resurected of course!!
