Explanation
True Airspeed (TAS) and Skydiver’s Airspeed (SAS) are two methods of calculating
the airspeed of a moving/flying/falling object.
TAS is a term used in aviation: It is the speed of an object relative to the surround-
ing air, regardless of the altitude.
SAS is a new concept developed by LARSEN & BRUSGAARD: SAS is the speed of a
skydiver calculated from measurements of air pressure and temperature and con-
verted to a fixed air pressure (875.3 mb) and a fixed temperature (+7.080C) which
corresponds to 4,000 feet ASL.
