Note

The angle or slope of Descent as given in the Range

Table is only correct when the gun and target are

on the same horizontal plane, the angle of sight

must be added to or deducted from the angle of

Descent given in the Range Table according as the

gun is in a plane above or below the target

__________________________________

Angle of Incidence  The angle which a tangent to the trajectory

at the point of impact makes with the

surface struck

__________________________________

Lateral Deviation; The distance of the point of impact of the

projectile right or left of the line of fire

or in other words the perpendicular distance

of the point of impact of the projectile

right or let of the plane of sight

Point Blank; A gun is laid point blank when the line

of sight is parallel to its axis
