ABSTRACT:
An instructional model. The model, in a preferred form, includes an indicator member that represents the instantaneous flight path of an aircraft. The indicator member has indica thereon that represents a range of attack angles at which the aircraft could fly relative to the instantaneous flight path. The indicator member also has indicia thereon that represents the center of pressure acting on the aircraft when flying at a selected attack angle. A second member that represents an aircraft is pivotally attached to the indicator member such that it can be selectively pivoted relative to the indicator member to an attack angle such that the center of pressure indicia identifies a point on the second member which represents a corresponding point on the aircraft at which the center of pressure forces are applied thereto when flying at that selected attack angle.
