Flight Path Angle
The flight path angle is the angle between the orbiting body's velocity vector (= the vector tangent to the instantaneous orbit) and the local horizontal. Under standard assumptions the flight path angle satisfies the equation:
where:
- is the specific relative angular momentum of the orbit,
- is orbital speed of orbiting body,
- is radial distance of orbiting body from central body,
- is the flight path angle

Famous quotes containing the words flight, path and/or angle:
“It is marvelous indeed to watch on television the rings of Saturn close; and to speculate on what we may yet find at galaxys edge. But in the process, we have lost the human element; not to mention the high hope of those quaint days when flight would create one world. Instead of one world, we have star wars, and a future in which dumb dented human toys will drift mindlessly about the cosmos long after our small planets dead.”
—Gore Vidal (b. 1925)
“For I must tell you that we artists cannot tread the path of Beauty without Eros keeping company with us and appointing himself as our guide.”
—Thomas Mann (18751955)
“The inhabitants of earth behold commonly but the dark and shadowy under side of heavens pavement; it is only when seen at a favorable angle in the horizon, morning or evening, that some faint streaks of the rich lining of the clouds are revealed.”
—Henry David Thoreau (18171862)
