An inspection of the curves in Figs. 1 1 and 1 2 shows the following : Lift with negative incidence. A cambered plane exerts a lift even at a small negative incidence. Zero lift is usually obtained when the incidence is between 2 and 4 (in Fig. Ii at 3) but in extreme cases the incidence may be decreased to 6 or 8 before zero lift is reached. Although in most cases an airplane flies with a positive incidence, at high velocities it may fly with zero incidence or with a small negative incidence, but not within two or three degrees of the point of zero lift.
