Real Values for MTOW/MLW 737ng

does Any body know the real Maximum Landing Weight for the 737-700 and -800?

In my company we have several airplanes that came from different airlines and everyone with a different MLW/MTOW and so.
I understand the certification, insurance, and leasing issues, but would like to know the boeing's numbers. What is the Real MTOW/MLW?

Thanks

Mr Becker - a little Googling would not hurt? http://www.boeing.com/commercial/737...f_700tech.html for MTOW for starters like 737ng says - rest for you

Punk have another read?

Then there is the ER/C etc.......

Thanks you guys!

So an overweight landing is not necessarily overweight in terms of aircraft strength. Just a matter of how much you paid for certification, is that correct?

BOAC

I just copied the weights from the Boeing FCOM

The Boeing Company
All Rights Reserved
Document Number D6-27370-TBC
November 20, 1997
Revision Number: 25
Revision Date: September 25, 2009

Unless it has been revised again these are the weights Boeing are giving out.

I guess this is the problem the original poster was talking about, there's different values from different sources.

Well, something is either wrong or you have an FCOM for a peculiar 700, as you can see. 70080 is the one I am used to for 'standard' 700

You can allways buy lower gross weight versions, those are a bit cheaper both from boeing and for airway dues, however for the latter there are other clerver schemes to save them (we can use a different MTOW each single sector depending on actual weight).

Hmmmm that is weird indeed may be that might be the case then.
If you can buy lower Gross weights then may be there isn't a standard weight for the aircraft.

I dont really know im just making my self clear thats where I got the info from and not just off flight sim

FCOMs are tailored for your company specs, so you may not see the absolute highest weight if you do not have it as an option.

As BOAC said Boeings website is a good source (other 737 websites are avaialable). Another good source is the Type Certificate Data Sheet, a copy of which is downloadable from www.b737.org.uk/a16we.pdf

Just for further confusion...

We have the 737-700IGW (Increased Gross Weight)

It's essentially a -700 with -800 wings and gear.

Our MTOW is 77,564 kg and MLW is 60,781 kg.

Slightly different to the PLTFORLIFE quote for the HGW version.

Cheers...FD...
