Hi dwsmith,Can a flight path angle be 356 degrees?

Depends on the way it's defined I presume. If it's defined as,

Originally it was -4 so I added 360 to get the positive. So I can then subtract and say it is positive?Hi dwsmith,

Depends on the way it's defined I presume. If it's defined as,angle between the flight path vector and the horizon(refer >>this<<) then 356 degrees will be the same as 360-356=4 degrees.

Kind Regards,

Where did you encounter this question and can you please tell us how the flight path angle is defined in the book that you use? I presume that it is defined as an angle in-between -180 and +180.Originally it was -4 so I added 360 to get the positive. So I can then subtract and say it is positive?

\gamma = \tan^{-1}\left(\frac{e\sin\nu}{1 + e\cos\nu}\right)

$$

where $\nu$ is the true anomaly and e is the eccentricity of the orbit.
