3. The figure shows the forces acting on an aircraft lying in steady flight (no acceleration) The steady-flight (or trim) equations can be expressed in a coordinate system aligned with the flight path as 4 Note that hr is not shown in the figure, but it represents the vertical distance between the center of gravity (the origin of the coordinates) and the thrust vector. In these equations, TE thrust WE aircraft weight DE aircraft drag LwE wing lift LH horizontal tail lift ? flight-path angle a ? aircraft angle of attack First, we must determine what is unknown. The unknown quantities depend on the problem to be solved, but a typical situation may be that the aircraft properties are known and a certain flight 3.
