Constants

  • altitudeAdjustmentFactorTable - Altitude adjustment factor at altitude (feet / 1000)
  • barometricPressureTable - Standard barometric pressure (inches Hg) at altitude (feet / 1000)
  • dropTable - currentVelocity/muzzleVelocity (feet per second / 1000)
  • speedOfSoundAtSeaLevel - (feet per second)
  • temperatureTable - Standard temperature (degrees F) at altitude (feet / 1000)
  • vaporPressureOfWaterTable - Vapor pressure of water (inches Hg) at temperature (degrees F / 2)
  • weightDensityOfAirAtSeaLevel - (pounds per cubic foot)

Functions

  • altitudeAdjustmentFactor(altitude) - Adjusts from the standard altitude (sea level) to the current altitude.
  • barometricPressureAdjustmentFactor(altitude, barometricPressure) - Compares the barometric pressure (inches Hg) at a given altitude (feet) to the standard barometric pressure at that altitude.
  • interpolateArray(array, arrayIndex) - Takes the nearest 2 numbers in a lookup table and returns a number between them.
  • relativeHumidityAdjustmentFactor(temperature, barometricPressure, relativeHumidity) - Compares the relative humidity (percentage) at a given altitude (feet) to the standard relative humidity at that altitude.
  • speedOfSound(altitude) - Speed of sound (feet per second) at a given altitude (feet).
  • speedOfSoundFactor(altitude) - The speed of sound factor compares the speed of sound (feet per second) at a given altitude (feet) to the standard speed of sound at sea level.
  • standardRelativeHumidity(altitude) - Compares the relative humidity (percentage) at a given altitude (feet) to the standard relative humidity at that altitude.
  • temperatureAdjustmentFactor(altitude, temperature) - Compares the temperature (degrees F) at a given altitude (feet) to the standard temperature at that altitude.
  • weightDensityOfAir(altitude) - Barometric pressure (inches Hg) at a given altitude (feet)
