Final Glide Settings

This screen as accessed from the “Settings Menu”

Percent Water

This value is used to represent the amount of water ballast being carried by the glider. 100% = Full ballast, 0% = None. The effect of ballast is included in the final glide calculations. The amount of ballast allowed is shown on the currently selected Polar page.

This value can be changed by pressing the Page-Up and Page-Down buttons.

Polar Potential

This value is used to degrade the theorectical performance of the glider. It can be used to allow for dirty or wet wings and other imperfections. A typical value is 95% i.e. 5% performance loss. This is a way of introducing a safety factor in the final glide calculations.

This value can be changed by pressing the Calendar and Phone buttons

Safety Height

This value is used in the calculation of the required altitude (R.Alt) and the delta altitude (D.Alt) These values will display the altitude required to arrive at your target waypoint exactly at the safety height. This value is also used when calculating terrain clearance of the Final Glide Over Terrain option is being used.

Note: the Arrival Height (A.Alt) value is an exact arrival altitude and does NOT allow for this safety height.

This value can be changed by pressing the To Do and Memo buttons

(See here for a more detailed explanation)

Set Avg MC after X Turns

When checked this option will update the MC (McCready) setting to the average lift encountered in the last 5 thermals. This updated value will then be used in all Soarpilot’s calculations.

You can set the number of turns required in a thermal, before it is included in the average calculation.

You can see details of the last 5 thermals on the Thermal History screen.

If you prefer a manually input of the MC value instead, uncheck this checkbox. The ToDo button increases the MC value and the Memo button decreases it when you are on the Final Glide or Moving Map screen. This is usefull for ridge and wave soaring.

Use Soarpilot Waypoints

When checked Soarpilot will use internal waypoints as the waypoint. This is the normal setting. When un-checked a single GOTO waypoint received from the GPS will be used.

Default to HOME Waypoint

When checked Soarpilot will by default select the HOME waypoint as the target as soon as the program starts. You must have the “Use Soarpilot Waypoints” option checked. Note: If you select this option, a waypoint will automatically be selected, so you will not be able to use SoarPilot without a GPS by using the Page-Up or Page-Down buttons to manually enter a distance.

Use Radial for Ref Wpt

This option controls if the Reference Waypoint information is displayed as a Radial From and Distance rather than a Bearing To and Distance. This information is display at the bottom center of the Moving Map screen if a Reference Waypoint is selected. Only 1 waypoint can be the Reference Waypoint.

Next Wpt Info

This option controls the display of the next waypoint information on the Final Glide screen and Moving Map screen. You must have the “Use Soarpilot Waypoints” option checked.

“ALL” means next waypoint information will always be displayed.
“CTL” means next waypoint information will only be displayed for Control Waypoints entered into a task, or the Min/Max points in a target area in an assigned area task.
“OFF” means next waypoint information will never be displayed.

Optimize STF for Speed

When chcked Soarpilot will display MC (McCready) values on the Final Glide and Moving Map screens. This is the normal mode for cross country flight. When un-checked Soarpilot will display Total Sink values which can be read from your variometer in flight.

Final Glide Over Terrain

When checked Soarpilot will check if you can safely to your target waypoint, and glide completely round the remaining waypoints in a task (if active) without encountering high terrain that would block your path. This option requires a terrain database to be loaded for the area round your target waypoint or task. See Creating & Loading Terrain Elevation Data for details.

Show Req'd Ground Speed

When checked this option will display your Speeds To Fly (STF) as the Required Ground Speed (RGS) not required airspeed taking into account any wind that may be present. This option is useful for paragliders or hangliders with no airspeed indicator as it allows the GPS ground speed to be used.

Note: the RGS value assumes you are flying directly to your target waypoint, but small differences (<20deg) in your bearing do not change the value significantly.
