Boeing 737 Specs

In the more than 40 years of its existence, the Boeing 737 has evolved from a stumpy little twin jet airliner into a family of high performance and versatile jet transports.

The global climate of rising fuel costs as well as increased competition in the form of the Airbus A320 have ensured that Boeing continue to bring out more improved versions of the type.

Below is a table of the main features and specifications for the Boeing 737 family of aircraft.

  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
