Read wind and temperature

Read the wind

FSS describes a polar wind vector and a Cartesian view with separate X and Y arrows. Use the displayed values only when the corresponding controls and indications are present in your build.

Read SAT

Static air temperature is the undisturbed-air reference described by FSS for performance and an OAT request.

Read TAT

Total air temperature includes the effect of motion through the air and is a different value from SAT.

Read TAS

True airspeed is the aircraft’s speed through the air; compare it with ground speed only after considering wind.

Check validity

FSS limitations say TAS, TAT and SAT are valid only above 60 kt. Avoid treating low-speed readings as reliable flight-performance inputs. ^{[10] [203]}
