Functions to calculate ICAO standard atmospheric properties: temperature, density, and pressure.
atmtemp(alt = NULL, units = NULL, ret_units = FALSE) atmpres(alt = NULL, units = NULL, ret_units = FALSE) atmdens(alt = NULL, units = NULL, ret_units = FALSE)
alt |
the altitude (above mean sea level). If excluded, sea level is assumed [m or ft] |
units |
character vector that contains the system of units [options are
|
ret_units |
If set to TRUE the value(s) returned are of class |
the temperature of air for the standard atmosphere for the atmtemp function [C or F]
the absolute pressure of air for the standard atmosphere for the atmpres function [N/m^2 or lbf/ft^2]
the density of air for the standard atmosphere for the atmdens function [kg/m^3 or slug/ft^3]

#Find standard atmospheric temperature at altitude 8000 m atmtemp(alt = 8000, units = 'SI') #Find standard atmospheric pressure assuming default altitude of zero (sea-level) atmpres(units = 'Eng', ret_units = TRUE) #Find standard atmospheric density at altitude 15000 ft atmdens(alt = 15000, units = 'Eng')
