what is the cg position of B 737-800 aircraft in front, side and top view ?

Author: Amy Adams  //  Category: Cg Computer Programming

people i am working on landing gear of B 737-800. i want to locate the cg position this aircraft. can any one cane help me on this .

Pilot’s don’t figure the CG vertically or laterally, generally my flights seem to be about 20% MAC.

    Which view…?
    Why 800…? – All 737 have a CG at about same location -
    A couple of feet forward of the main gear -

    About same location does NOT mean fixed point –
    See definition of "about" in dictionary -
    Indeed CG moves in flight, especially with tanks in swept wings -
    CG are generally 2 or 3 feet forward of main gear -
    There are forward and aft limits of CG –

    A "fixed" CG is also computed for "empty airplanes" -
    Given alongside the "mean aerodynamic chord" and "LEMAC" -
    New CG is recomputed every time airplane goes through "D" checks -

    Caretaker, you claim to be ex-F/E P2V and 141, you surprise me -
    All the F/Es I know are sharp knowledgeable people -
    You do not fit that description -

    I do not need to demonstrate my knowledge of airplanes -
    It was showed my expertise multiple times here on this forum -

    You can verify my FAA certificates/ratings which are public records -
    Would you like my name to check my qualifications…?
    Give me yours, I would like to check your own records too -

    Somebody stepped on their crank. The cg is dependent on the load and varies from flight to flight. In the old days there was a slide rule for each aircraft to determine where loads would be placed in relationship to the effect on cg.

    It also changes during a flight as fuel burns off. That is one of the calculations a Flight Engineer had to monitor until the position was taken over buy computers.

    Skipper I’ve seen you make a lot of childish mistakes but when you say the aircraft cg is a fixed point, you blew it big time. You are phoney even if you are getting better at your answers.

    Check it out by any source. Aircraft cg is not fixed and any commercial pilot knows that.

    @Caretaker..
    EMPTY aircraft has a fixed CoG unless you remove some substantial mass from the airframe.

    @Warbird.. you’d be surprised that helicopter pilots DO calculate lateral position of CoG
