N.B; The angle of Elevation and the Quadrant-Angle

are the same when the lone of sight is horizontal


 Drawing of a diagram showing the relationship between line of sight, axis of gun (or piece), angle of sight, angle of elevation, quadrant angle, and horizontal plane 

_____________________________________

Line of Departure the direction of the projectile on leaving the

muzzle, or in other word a tangent to the

projectile at the muzzle

_____________________________________

Plane of Departure; the vertical plane passing the

line of departure

_____________________________________

Angle of Departure; The angle between the line of departure

and the horizontal plane in other words

_____________________________________

Battery angle The Angle formed by lines Drawn
