2. Focal mechanism - Wikipedia

   en.wikipedia.org/wiki/Focal_mechanism

   The take-off angle is the angle from the vertical of a seismic ray as it emerges from the earthquake focus. These angles are calculated from a standard set of tables that describe the relationship between the take-off angle and the distance between the focus and the observing station.

3. Aircraft flight dynamics - Wikipedia

   en.wikipedia.org/wiki/Aircraft_flight_dynamics

   Aircraft flight dynamics. Flight dynamics is the science of air vehicle orientation and control in three dimensions. The three critical flight dynamics parameters are the angles of rotation in three dimensions about the vehicle's center of gravity (cg), known as pitch, roll and yaw. These are collectively known as aircraft attitude, often ...

4. Takeoff - Wikipedia

   en.wikipedia.org/wiki/Takeoff

   Takeoff is the phase of flight in which an aerospace vehicle leaves the ground and becomes airborne. For aircraft traveling vertically, this is known as liftoff. For aircraft that take off horizontally, this usually involves starting with a transition from moving along the ground on a runway. For balloons, helicopters and some specialized fixed ...

5. Wing loading - Wikipedia

   en.wikipedia.org/wiki/Wing_loading

   Aircraft with low wing loadings tend to have superior sustained turn performance because they can generate more lift for a given quantity of engine thrust. The immediate bank angle an aircraft can achieve before drag seriously bleeds off airspeed is known as its instantaneous turn performance. An aircraft with a small, highly loaded wing may ...

6. Angle of attack - Wikipedia

   en.wikipedia.org/wiki/Angle_of_attack

   Angle of attack. In fluid dynamics, angle of attack (AOA, α, or ) is the angle between a reference line on a body (often the chord line of an airfoil) and the vector representing the relative motion between the body and the fluid through which it is moving. [1] Angle of attack is the angle between the body's reference line and the oncoming flow.

7. Lift-to-drag ratio - Wikipedia

   en.wikipedia.org/wiki/Lift-to-drag_ratio

   Lift and drag are the two components of the total aerodynamic force acting on an aerofoil or aircraft. In aerodynamics, the lift-to-drag ratio (or L/D ratio) is the lift generated by an aerodynamic body such as an aerofoil or aircraft, divided by the aerodynamic drag caused by moving through air. It describes the aerodynamic efficiency under ...
