Need help converting SI [Qthrust] 2*15570.01] to US standard for static thrust

  • Google:
    input: "15570 N in lbf"
    result 3500. pound force

    Caution pound FORCE (lbf) not pound mass (lbs),
    since f = m * a, (factor 9.81N/kg ~ 10 - the factor which you were probably missing),
    (lbf is a force, lb is a mass unit)

    Similar issue would be weight in N and mass in KG. Weight depends on the gravity (9.81 N/kg on Earth's surface), whilst mass would be constant. But a lot of people say aircraft weight = ...kg, which is incorrect. Therefore nowadys we lern abbreviations like MTOM instead of MTOW or MLM (max landing mass) instead of MLW at the university. In the Aerofly FS 2 there also is no such thing as a weight parameter. We only use "Mass" and calculate the gravitational force from that.

    And yes that is 15.57 kN per engine: 15570N / ( 1000N / kN ) = 15.57 kN, no zeros required?!

    Wow Jan

    I'm impressed!!!!
