The body axis system, denoted by a subscript b b, originates at the aircraft center of gravity. The positive direction of the xb x b -axis is towards the front. The positive direction of the yb y b -axis is towards the right wing tip, and the positive direction of the zb z b -axis is towards the bottom of the aircraft.

Introduction: The "principles of flight" are the aerodynamics dealing with the motion of air and forces acting on an aircraft. Lift is the most apparent force, as it's what gives an aircraft the ability to fly. Thrust provides a method with which to move the aircraft.
Imagine three lines running through an airplane and intersecting at right angles at the airplane’s center of gravity. Rotation around the front-to-back axis is called roll. Rotation around the side-to-side axis is called pitch. Rotation around the vertical axis is called yaw.
Longitudinal, Lateral, and Vertical Axis. The longitudinal axis is an imaginary line running from the nose to the tail of the aircraft; motion about this axis is called "roll," controlled by the ailerons. Longitudinal stability is the tendency of an aircraft to return to the trimmed angle of attack.
Each axis of flight is an imaginary line around which an airplane can turn. Think of an airplane rotating around an axis like a wheel rotates around an axle. Regardless of the type of aircraft, there are three axes upon which it can move: Left and right, forwards and backwards, up and down. In
In this set of lectures we will focus on the flight mechanics of entry and descent vehicles, with an emphasis on: - deriving the necessary differential equations - modeling gravity and aerodynamic forces - numerically integrating the differential equations 4 Basic Assumptions • Single, rigid, flight vehicle without rotating masses
