    737 Control Column Pressure.

    Hi,

    I've been looking at the excellent home cockpit web site at http://www.flaps2approach.com

    It says that the pitch pressure on a B737 is designed to be 37 pounds +-4.

    Am I correct in assuming that it's a constant/linear pressure through the full movement when there is no airflow over the wings and, that when the aircraft is flying the pressure increases with the pitch angle?

    Thanks

    Andrew

    Re: 737 Control Column Pressure.

    Hi Andrew,

    Fom w Irecall it wa 30 pounds on the 767 that it standard for most Boeings but you might be right on the 37 pounds.

    The airflow over the wings have nothing to do... These Aircraft have articfial feel units which basically throws the feedback from the flight controls. I did not fly 737 but the E-190 was this way and it Is modeled from the 737

    regards

    Re: 737 Control Column Pressure.

    Thanks for your reply.

    If I understand you correctly, the aircrafts hydraulic system produces a constant force on the column over the whole pitch range (in flight) and, assuming the trim is neutral, will go back to its centre position when the pilot releases the yoke?

    Thanks
