The Constant Setup
The Constant Setup Page allows
you to fine-tune certain aspects
of the planned jump.
All jump types also can use a
“Percent Max” to increase or
decrease the range or their jump.
Entries less than 100% decrease
drift distance to the DIP while
those greater than 100% increase drift distance. More
experienced jumpmasters may choose to use smaller
numbers while those less experienced may use larger
numbers.
Safety Factor is used in HAHO jump types to allow
a margin or error for a jump. Safety factors are
usually integer values, no smaller than two, and are
determined by the jumpmaster based on specifications
for the jump.
A number of K values can be specified for different
jumps. HAHO jumps use K-open while HALO jumps
use K-open and K-freefall. Static jumps use K-static.
K-values are based on the parachute canopy rating.
Each parachute should be labeled with a K value.
Common values may range from 3.0 for K-freefall to
48.0+ for HAHO K-open.
To use the Constant Setup Page:
1. Highlight each field in order, and press Enter
to open the numerical key pad.
2. Enter the appropriate value in each field, select
OK, and then press the Quit key to return to
the Jumpmaster Setup Page.
Clicking the Goto HARP button begins the
navigation process and will take you to the Wind
Setup page if that information is missing or
automatically setting up the route with the calculated
HARP and then the selected DIP before taking you to
the Navigation page.
A check box at the bottom allows for auto-navigation
to the DIP. If you want your unit to determine when
you have jumped, this box should be checked. A
message appears describing how to manually navigate
the route.
Select Restore Defaults from the Option Menu of this
page to reset the values.
