same body position), whereas TAS will show a different speed throughout the dive
(the same body position, different air density).
Below are some recommendations and numbers for SAS:
A good base speed should be: 110-115 mph.
A high base speed should be: 120-125 mph (tendency to wobble when docking).
A slow base speed should be: 100-105 mph (jumpers start to go low).
See separate section on page 61 for more information about TAS and SAS.
