### In flight usage

Cumulus permits the use of the keyboard to minimize the use of the stylus or directly touching the screen while in flight. You can, however, also access the same functions via the menu. The following keys are defined in GPS mode:

- W - Select a waypoint
- E - Display a list of reachable points where you can land.
- I - Information on current waypoint
- R - Remember current position as waypoint
- A - Toggle display of waypoint labels
- Z - Zoom in
- X - Zoom out
- Cursor right - Zoom in
- Cursor left - Zoom out
- V - Zoom to waypoint
- L - Toggle logging
- T - Select task
- P - Show Pre-flight settings dialog
- F - Show In-flight settings dialog
- G - Show GPS status
- Cursor up - Increase McCready value
- Cursor down - Decrease McCready value

If you are working in manual navigation mode, there are more keys available to control Cumulus. See here for more details.

You can also get information on objects on the map by typing them with the stylus (or your fingernail). Airspace structures and airfields will display an information box on the screen that contains basic info on the object selected. If you type and hold an airfield, you will get detailed information on the selected airfield, just like you would for the selected waypoint if you press I. In this menu you can also add the listed airfield as a new waypoint or select it as your waypoint.

Use Zoom to waypoint to get the waypoint you selected into view on the map. Cumulus will try to display the selected waypoint near to the edge of the map. The selected waypoint's name is displayed in reverse colors as the other names. Depending on the distance to the waypoint, the waypoint may be too far away to show on the map because the zoom factor would exceed it's minimum. In that case, a message is shown in the bottom of the screen (in the taskbar area). If the waypoint is too close, the zoom is set to maximum and the waypoint may be further from the edge than normal.

Waypoint labels may be turned off and on by pressing A. The default is set in the Map configuration tab.

Logfiles are written in the IGC file standard. They are placed in the document section, so you can easily transfer them to your desktop, beam them to your friends or analyze them using KFLog/Embedded.

Tasks are routes between waypoints, which are handled as turnpoints here. They can be created and modified in the Pre-Flight setting dialog under the tabulator task. Tasks stored from there are automatically shown in the task selection dialog. Tasks are drawn in thick purple lines, and turn points are drawn with the correct photo sectors drawn in red and green.

Prior to the flight, you should select the glider you're flying with and enter the amount of water you've taken with you. You can do that in the Pre-flight settings. On the second tab, you can select a task.

In-flight settings are values that may change in-flight. These are the amount of water you still have, the bug factor and the McCready setting.
