Preflight Settings

Common

Here you can enter different common preflight data.

Arrival Altitude

The arrival altitude is your preferred altitude above terrain when on final glide. It is used for the calculation of the glide path value. The value entered here is added to the elevation of the selected target. The arrival altitude is given in meters, if altitude unit meters is selected. Otherwise foot is used. For most situations, the default 200 meters would be sensible.

QNH

The QHN must be entered in hPa (Hecto Pascal). It is only considered in the warning distance calculation to standard pressure airspaces. The default value is 1013hPa.

Logger Interval

Interval for logging of IGC data records. Default time is 10 seconds. Note, that lower times  will increase the log file size.

Autostart logging

If you activate this check box, cumulus starts automatically the IGC logging, when you start with moving.
