tangent elevation मीनिंग इन हिंदी

Instead, the sight mount had both Tangent Elevation ( TE ) and Angle of Sight Scales and a separate Gun Rule to convert range into TE, corrected for the muzzle velocity variation from standard.
Since the light gun entered service after the introduction of field artillery computer equipment ( FACE ), it never, unlike the Abbot, had gun rules ( large slide rule like instruments used at each gun to convert range in metres to tangent elevation in mils, taking account of muzzle velocity ).
