coolAltitude for iPhone

Description

coolAltitude is easy to use tool designed for IFR pilots to help them with calculations of temperature corrections during ILS (CATI), RNAV/GNSS, VOR and NDB approaches in cold weather. It can decode SNOWTAM reports from METAR information.The strength of the tool lies in the amount of values you need to enter. Nobody is really willing to fill a lot of data to get simple calculation result. So the only data you need to enter are:Intermediate approach altitudeDescent angle of the approachMinimumsRunway elevationAnd, of course, the temperature at the airportMSA and Go Around altitudes, if requiredOptionally you may need to enter DME shift to work with DMEs offset from runway threshold.Optionally SNOWTAMAs a reward for your effort you get in graphical and handy form:Temperature corrected altitudes for all entered valuesTemperature corrected altitudes for altitudes above the intermediate approach altitudeTemperature corrected altitudes for all relevant DME distances rounded in the way which makes them easy to useTemperature corrected descent angle for FPA enabled airplanesPressure altitude of the airport in hectopascalsTable with temperature corrected (and uncorrected) values of vertical speeds (ft/min) during descend for different ground speeds (kt)Table with conversion between QFE values in meters and QNH values in feet, of course with temperature corrected altitudes as well. All optimized for use in Russian regionsDecoded SNOWTAM including braking actions based on friction coefficient according ICAO as well as Normative/CIS scales. It provides (experimental) recommendation for braking actions based on runway contaminant and airport temperature.Corresponding aviation authority can certify this tool. It must be the part of operators EFB package. Otherwise it cannot be used in real operations.
