Jump Run Manual

The Jump Run tool is used to review a proposed aircraft jump run, forecast winds aloft, cloud information, drift references, canopy range, and selected map landmarks.

Inputs and controls

Input or control	Explanation
Latitude / Longitude	The selected drop zone, target, or map reference point used for the display.
Time	The forecast time used to request winds, clouds, and weather conditions.
Exit altitude	The planned aircraft exit altitude used to evaluate winds at and below planned exit.
Under canopy altitude	The altitude where the jumper is under canopy. This is not the parachute deployment altitude.
Glide ratio	The canopy glide value used to estimate still-air or wind-adjusted return range.
Descent rate	The canopy descent rate used with glide ratio and wind layers to estimate return range.
Back-by altitude	The altitude the user intends to reach the selected target by.
Jump run heading	The proposed aircraft track in degrees true. The display may also show a magnetic reference when available.
Groups	The number of groups used when displaying group exit spacing along the jump run.
Spot distance	Distance forward or back along the jump run used to adjust the relationship between the selected point and displayed exit reference.
Offset	Lateral adjustment left or right of the jump run used to review an offset spot.
Heat map / angle option	Displays colored planning overlays around the jump run and canopy return area when enabled.
High pull / hop n pop options	Adjusts the planning context for higher canopy altitudes or lower exit profiles when available.
Refresh forecast	Requests updated forecast data for the selected location and time.
Current conditions	Moves the forecast reference to current or near-current conditions when available.

Outputs and display references

Output	Explanation
Jump run line	The displayed aircraft track across the map.
Exit points	Estimated group exit locations based on selected heading and spacing assumptions.
Earliest / last exit	Reference distances that describe the displayed exit window relative to the selected point.
Freefall wind reference	A visual reference for forecast winds affecting the freefall or drift review portion.
Canopy wind reference	A visual reference for forecast winds affecting canopy flight planning.
Canopy range circle	An approximate range reference for returning under canopy using the selected canopy parameters.
Hazard / planning overlays	Colored areas that help compare the jump run, canopy return area, and nearby geographic landmarks.
Winds aloft panel	Forecast wind direction, speed, and temperature by altitude layer.
Cloud data	Forecast cloud information shown as a planning reference.
Jump conditions	Environmental reference values such as twilight or other available forecast-derived information.
Barometric altimeter error	The expected deviation of barometric altimeters from true altitude under the given environmental conditions.
Forecast time slider	Allows review of forecast changes across available time steps.
