A Winds aloft chart shows detailed information from station identifiers from where the wind is forecast, wind direction, wind speed in knots and wind temperature (at 24,000ft it is assumed that temperature is always negative) at varying altitudes, all of which can be found within RocketRoutes features. When flying online, the winds aloft at cruise altitude (like FL350) never exceed 30 knots. If youre just looking for a rough estimate though, you can calculate your TAS mentally by just adding 2 percent of the CAS for every thousand feet of pressure altitude. I understand that if there is a surface head wind, most of the time you land into the wind. 2015-02-22, 11:19:24 .

A Winds aloft chart shows detailed information from station identifiers from where the wind is forecast, wind direction, wind speed in knots and wind temperature (at 24,000ft it is assumed For example, 350 -Will (Dragonfly) Likes: JimInPB. In order to read this, subtract 50 from the direction (75-50=25) and add 100 to the speed W/T Plots. Subtracting 100 knots from the speed and They follow the format ddfftt, where dd is the wind direction (true), ff is the wind speed (in knots) and tt is the temperature (in degrees Celsius). For example, 810550 would be 310 degrees (80-50) at 105 knots and the temperature is -50C. A long barb and a short barb is 15 knots, simply by adding the value of each barb together (10 knots + 5 knots = 15 knots). :-) rolando751 Wrote:After disabling true wind aloft the speed dropped but the direction was still wrong as I was expecting headwind(265).Hm, yes, disabling the option 'True winds aloft' actually will result in not very accurate winds aloft which In the STL forecast, the coded group at 39,000 ft. is 731960. URL Options. If the wind speed is over 100 knots, a "special code" is used in which 50 is added to the two wind direction digits, to signal you to add 100 to the wind speed. Airplane doesn't even know you're moving with the airmass at another 50 knots. You can use winds aloft for the big picture to predict the patterns and hazards youll encounter.
