Elliptic Orbit - Flight Path Angle

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 galaxy’s 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 planet’s dead.
    Gore Vidal (b. 1925)

    Another danger is imminent: A contested result. And we have no such means for its decision as ought to be provided by law. This must be attended to hereafter.... If a contest comes now it may lead to a conflict of arms. I can only try to do my duty to my countrymen in that case. I shall let no personal ambition turn me from the path of duty. Bloodshed and civil war must be averted if possible. If forced to fight, I have no fears from lack of courage or firmness.
    Rutherford Birchard Hayes (1822–1893)

    The good lawyer is not the man who has an eye to every side and angle of contingency, and qualifies all his qualifications, but who throws himself on your part so heartily, that he can get you out of a scrape.
    Ralph Waldo Emerson (1803–1882)
