Enter your data in the areas provided below. Select the "Calculate" button when all fields are filled. If the field is blank, the default (shown in brackets) is used.

Range Data

Near Velocity (600 to 4500 ft/sec)

Far Velocity (500 to 4400 ft/sec)

Distance Apart (1 to 600 feet) 

Drag Function 


Temperature (-40 to 140 degrees Fahrenheit)

Pressure (15 to 40 inches Hg)

Relative Humidity (0 to 100%)

Altitude (-1000 to 15000 feet)

Checking standard conditions at altitude cause the temperature, pressure and humidity to be adjusted for the given altitude, otherwise the air density is calculated from the temperature, pressure and humidity using the ICAO Standard Atmosphere.
