    Hi,

    Could you please clarify the full name and physical meaning of the following parameters:
    1.Pt2
    2.TAT
    3.WFuel
    4.VAFN
    5.VBV

    Thanks!

    Ambient Conditions:
    Pt2 — Total pressure at fan inlet, also known as dynamic pressure (ambient pressure with Mach number effect)
    TAT — Total air temperature at fan inlet, again higher than ambient temperature for non-zero Mach number
    Actuator Positions:
    WFuel — Fuel flow to combustor
    VAFN — Variable area fan nozzle
    VBV — Variable Bleed Valve

    These parameters are measured using sensors on the engine, except Pt2 which is provided by an aircraft sensor.
