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)
