    At first glance, the ALTITRACK™ looks like many of the more common analog altimeters used throughout the world... but look a little closer. The ALTITRACK™ is the only sport altimeter with an analog face, but utilizes the most high tech and durable digital components for accuracy that surpasses every other mechanical sport altimeter currently available.

  • Page 60: Tas And Sas

    18 - TAS and SAS Definitions 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 surrounding air, regardless of the altitude.
  • Page 61 Example: A skydiver (in a fixed freefall position) who has a terminal fallrate of 62 meters/sec at 10,000 feet will have a terminal fallrate of 50 meters/sec at 3,000 feet. It will be seen that the difference in altitude (air pressure) makes it difficult to compare the fall-rates when measured using TAS.
  • Page 62 you are jumping at, SKYDIVER’S AIRSPEED (SAS) will be the same for the same body position. SAS is very useful when doing big formation skydiving. If using TAS, it will seem like the base is slowing down the fall rate during the entire skydive. To set TAS / SAS see paragraph 10.10.
