Density Altitude Calculator

Enter Fahrenheit Temperature Here C = (5/9)*(F-32) *** F = C*(9/5)+32 Converts Fahrenheit to Celsius Temperature Fill in the information and then click on the button. Enter the Airport Elevation Here = AE (feet) Enter Air Pressure at AirPort = 29.45 inches Hg Enter Out Side Temperature Here = OAT Degrees Celsius DA = Density Altitude in Feet Here is the Formula Used: ISA = 15 - 2*AE*(1/1000) = Temperature Difference = -2 per 1000 Feet PA = AE + 1000*(29.92 - 29.45) = Pressure Altitude (Difference in Pressure) DA = PA + 120*(OAT - ISA) 29.92 = Standard Sea-Level Pressure 15 = Standard Celsius Temperature at Sea-Level Here is the simple way to calculate this: Take the Airport Elevation = AE Divide AE by 1000 => 5000/1000 = 5 Now multiply by 2 => 5*2 = 10 Now subtract this from 15 => 15 - 10 = 5 This is your ISA => OAT - ISA = 35 - 5 = 30 => 120*30 = 3600 Set your altimiter to 29.92 and read your altitude = PA = 5470 feet => DA = PA + 3600 => 5470 + 3600 = 9070 feet Enter Celsius Temperature Here C = (5/9)*(F-32) *** F = C*(9/5)+32 Converts Celsius to Fahrenheit Just Take the Blue Pill and Remain in Bliss!
