The main view of Cumulus consists of three information areas, displays containing flight information, a map and a status bar. This screen is also called the map view.
Flight information
The indicators on the left side indicate:
Map
The map displays a graphical representation of the current
position (indicated by the intersection of the fuselage and the wings
in the glider symbol) and heading (indicated by the rotation of the
glider symbol). If there is no GPS fix, Cumulus displays an X symbol in
stead of a glider. See
manual navigation mode for more details. The current scale is
displayed in the scale indicator in the lower right corner of the map.
The map shows the terrain elevation by using colors. The detail level
of this display changes with the zoom factor: more zoom is more detail
in the terrain shapes. You can turn off the drawing of the elevations
from the Map Settings
dialog.
Depending on the maps you installed, Cumulus displays airports (the
type is indicated by the standard ICAO symbol), cities (yellow),
highways (red/white), roads (red) and railroads (dark grey), water
(blue). Not all details are displayed in all zoom factors. Also Cumulus
displays airspace structures. The different types are indicated by
using different colors. For basic information on an airport or airspace
structure simply touch the related symbol or area on the screen. You
will get displayed then the info on the interesting object in a pop up
window. The window disappears after a certain time automatically. This
time behaviour can be configured more in detail in the menu General
Setup under the tab Information.
If you press an airfield icon, you will get detailed information
on this item. You can add airfields to your waypoint list if it isn't
in the list already. Added waypoints will have a normal
priority.
Cumulus can calculate what airfields or waypoints are in reach. These
waypoints get a green circle beneath them. If a point is within reach
below the entered safety altitude, it gets a magenta circle beneath it.
The line to the currently selected waypoint is colored to match, and
will be in red if the waypoint is not within reach.
Status bar
The status bar displays the following things:
The first item with the name Menu toggles the menu bar by tipping on it.
The second items tells the mode Cumulus is operating in. If no GPS connection has been established this item will set to Man. Otherwise it will set to GPS and the number of received satellites.
The third item in the status bar is a combination between logging and flight indicator. It displays at the left side a L if IGC logging is enabled and fills the background with green color. Ls is displayed if the logger is in standby mode and the background is filled with yellow color. The flight status symbol is either shown in the center of the box alone, if logging is not active or right beside of the logging indicator.
The following characters are used for flight state display:
If you want to maximize the screen area for the map display, you can disable the status bar via the menu entry View/Statusbar.
Glide path
The glide path indicator
gives you an estimation on whether or not your selected target is in
reach. It calculates the performance of your glider using the entered
polar-values on the Settings dialog's
Glider tab. It
is assumed that you fly at the indicated best airspeed for the current
McCready value. You can enter a minimal arrival altitude on the
Personal tab.
If the indicator shows a negative value, you are under glide path and
the target is not in reach. If you are above glide path, the target is
in reach, and you can probably fly a bit faster to reach it sooner,
depending on the polar of your glider.
