1. Why has Boeing maintained its designation to be B737, despite the latest B737 bears little resemblance to the original variant of the B737?

   • Hi and thanks for stopping by. I suppose you have to look at the 737 as an aircraft class that is targeting a certain segment of the market. The Boeing 737 is designed to fill the smaller jet airliners space over a given range of seats. Whilst bigger than the Embraer E-Jets, Boeing feels this is an optimum size range for a small city jet which can also be used for medium-haul international services.

     If you look at your favourite model of car, you would see that they have also evolved over time to be something unrecognisable from their ancestors. Gains in technology as well as traveller expectations, continue to drive aeroplane makers to come up with improved, more cost efficient and more comfortable versions of their offerings.

2. Do you have the estimated production material used for the 737 Next Gen? I know the 787 is moving toward using more composite materiel instead of aluminum. Is the same happening with the 737?

   • Hi Shawn,

     it seems that Boeing has not leaped ahead with the 737 as much as they have with the 787. The use of composite materials in the 737 Next Gen or even the 737 Max is quite conservative. Aluminium alloys are still the mainstay of the construction materials used with various blends used according to the strength required for the particular component.

     For Example:
     Slats, flaps and Fuselage skin – areas primarily loaded in tension – Aluminium alloy 2024 (Aluminium and copper)

     Wing lower skin – Aluminium alloy 7055 (Aluminium, zinc, magnesium and copper)

     Wing ribs, Frames, stringers, keel and floor beams – Aluminium alloy 7075 (Aluminium and zinc)

     Spars, beams and Wing upper skin – Aluminium alloy 7178 (Aluminium, zinc, magnesium and copper)

     Landing gear beam – Aluminium alloy 7175 (Aluminium, zinc, magnesium and copper)

     I hope that helps.

     Cheers Peter

3. Hi. I am looking for a wheelbase in one main shin and the pressure in the wheel ( Boeing 737-500)

   • Hi and thanks for your question. For the wheels, I will give you two measurements. The wheelbase which is the distance from the nosewheel to the line between the main wheels, which is 11.07 metres. The wheel track, which is the distance between the main wheels is 5.25 metres. The nose wheel pressure in PSI is 186-194. The main wheel tyre pressures are 193-202, once again PSI.
     Happy Flying.

4. Hi. I am looking to build a prototype of Boeing 737 for numerical simulation purpose. Can you please tell me where to look for the cabin height,width, seat height, width and door to door length. from cockpit door to the kitchen alley .

   • Hi Anumula,

     thank you for stopping by. I found this image that might have some of the answers you need. Click here.
     We’d love you to share what you build when you’re done. Best of luck.
     Cheers Peter

5. hello, i would like to know about the technology which applied on B737 NG flight cockpit lay out include it’s characteristics (advantages and disadvantages), especially on PFD and MFD, can you tell me or send me a link which discuss about that?

   • Hi Andrey,
     It sounds like you have a bit of a project on your hands. The information is surely out there, but maybe the questions need to be a bit more specific.
     Good luck.
     Cheers Peter

6. Hello, do you know the meaning of the 737-8K5 designation and its background? The aircraft look like standard -800s, so why the difference?

   • Hi Ben,
     You are right, it does look very much like a 737-800. That is because it is an 800. It is simply an 800 with certain modifications that might have been stipulated by the customer airliner. In this case I believe TUI fly is the main customer. We don’t actually have access to a table of these variants and their features. If anyone does, please feel free to share with us all.
     Thank you.
     Cheers Peter

       Thank you for your reply. I cannot find any more information anywhere, but if I stumble across it, I will be sure to post it!
