User manual GARMIN JUMPMASTER SOFTWARE GUIDE

[. . . ] The Jumpmaster follows military guidelines for calculating a jumpmaster's high altitude release point (HARP). The accessory can auto-detect when you have jumped to begin navigating toward the desired impact point (DIP) using the barometer and electronic compass.

November 2002 2 Part Number 190-00219-02 Rev. B The Jumpmaster Page The Jumpmaster page allows you to set the jump type to one of three types (HAHO, HALO, or Static). The jump type selected determines what additional setup information is required. For all jump types, altitudes (drop or opening) are measured in feet above ground level (AGL). The drop altitude of at least 1, 000 feet must be specified next, and for HAHO jumps, it is assumed the drop altitude is the same as the opening altitude. For HALO jumps, the required information is the same as the HAHO jump type, plus an opening altitude. Common values for an opening altitude range from 2, 000 to 6, 000 feet AGL. For Static jumps, a drop altitude of at least 1, 000 feet must be specified. A constant wind speed and direction for the duration of the jump is assumed. For HAHO and HALO jumps, wind speeds and directions can be entered for every 1, 000 feet of canopy drift (CD) and every 2, 000 feet of free fall drift (FFD). These wind speeds are entered on the Wind Setup page by selecting the Wind button. "Forward Throw" and "Course to HARP" allow a user to determine the direction and magnitude the aircraft will carry him after jumping and before freefall or canopy drift begins. A number of additional constants are entered on the Constant Setup page by selecting the Constant button. If you want your Vista to determine when you have jumped, this box should be checked. 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 calclated HARP and then the selected DIP before taking you to the Navigation page. The Wind Setup Page Wind speeds and directions are added on the Wind Setup page. [. . . ] Common values may range from 3. 0 for K-freefall to 48. 0+ for HAHO K-open. Select "Restore Defaults" from the Option Menu of this page to reset the values. 3 Definitions The following is a list of abbreviations and acronyms commonly used by military jumpmasters that also relate specifically to this accessory: AGL CD DIP DZ DZSTL LFFD HAHO HALO HARP MSL NOAA PRP Above Ground Level Canopy Drift Desired Impact Point Drop Zone Free Fall Drift High Altitude High Opening High Altitude Low Opening High Altitude Release Point Mean Sea Level Primary Release Point Altitude measure drift while parachute is open location where landing should occur area where landing should occur drift before parachute is open type of jump type of jump location jumper exits from aircraft Altitude measure HARP plus forward throw of aircraft Drop Zone Support Team Leader National Oceanographic & Atmospheric Administration The following list of additional terms are often used by jumpmasters: Drop Altitude Forward Throw HAHO Jump HALO Jump K values Opening Altitude Static Jump Altitude when jumpmaster exits aircraft, measured in AGL Horizontal distance traveled by due to aircraft speed Type of jump where the jumpmaster jumps from a very high altitude and opens chute at a high altitude Type of jump where the jumpmaster jumps from a very high altitude and opens chute at a low altitude Wind drag values for parachutes Altitude when jumpmaster opens chute, measured in AGL Type of jump where wind speed and direction are assumed constant for the duration of the jump The following "typical" example is used in jumpmaster training courses. While the solution to this problem is outside the scope of this document, this example is included to give an idea of the capabilities of the Jumpmaster accessory. [. . . ]
