    I am programming a Flash game that uses these formula for my airplane-

    A general formula for lift: L = (1/2) d v(squared) s CL

    L = Lift, which must equal the airplane's weight
    d = density of the air due to altitude(ignored)
    v = velocity of the aircraft
    s = the wing area of an aircraft in square feet(ignored)
    CL = Coefficient of lift , which is determined by the type of airfoil(ignored) and angle of attack

    Thin Airfoil Theory (basically a 2d airfoil of infinite width hence no stall) for calculating CL:
    CL = 2 * pi * angle of attack

    The angle of attack is the difference in rotation between the airplane and the angle it is moving.
