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:
“When the flight is not high the fall is not heavy.”
—Chinese proverb.
“Tired,
she looked up the path
her lover would take
as far as her eyes could see.
On the roads,
traffic ceased
at the end of day
as night slid over the sky.
The traveller’s pained wife
took a single step towards home,
said, “Could he not have come at this instant?”
and quickly craning her neck around,
looked up the path again.”
—Amaru (c. seventh century A.D.)
“Modesty is the only sure bait when you angle for praise.”
—Philip Dormer Stanhope, 4th Earl Chesterfield (1694–1773)
