29
RTd – rifling twist direction (right = clockwise from
the shooter’s perspective)
Click
– assigns an angular value to sight clicks
DsF
- drop scale factor
Eunit
elevation unit – The units used for elevation
adjustments (Eclick). Can be mils, clicks, tmoa (True
Minute of Angle), smoa (Shooter’s Minute of Angle).
Eclick – elevation adjustment necessary for the firing
solution in the units specified above.
Wunit – windage unit – The units used for windage
adjustments (Wclick). Can be mils, clicks, tmoa (True
Minute of Angle), smoa (Shooter’s Minute of Angle).
Wclick
– windage adjustment necessary for the firing
solution in the units specified above.
Environment screen
update
– controls whether values for temperature,
barometric pressure, and relative humidity are
obtained automatically (yes) (from the Kestrel’s weather-
meter functions) or are manually set by the user (no)
lat – allows the user to specify the latitude that will be
used when calculating Coriolis corrections
Temp – temperature
sp
– station pressure (actual pressure at the
gun’s location)
RH – relative humidity
Dalt – density altitude (calculated from pressure,
temperature & humidity)
spin Drift – controls whether Spin Drift corrections are
included in ballistics calculations
Wcap
– toggles between applying windage correction
to just the current active target (one tgt) or to all targets
