hours. By doing this, the Weather Projection Station will not mistake the new
location as being a possible change in air-pressure when really it is due to the
slight change of altitude.

WEATHER TENDENCY INDICATOR

Working together with the weather icons is the weather tendency indicators
(located on the left and right sides of the weather icons). When the indicator
points upwards, it means that the air-pressure is increasing and the weather is
expected to improve, but when indicator points downwards, the air-pressure is
dropping and the weather is expected to become worse.
Taking this into account, one can see how the weather has changed and is
expected to change. For example, if the indicator is pointing downwards
together with cloud and sun icons, then the last noticeable change in the
weather was when it was sunny (the sun icon only). Therefore, the next
change in the weather will be cloud with rain icons since the indicator is
pointing downwards.
Note:
Once the weather tendency indicator has registered a change in air pressure,
it will remain permanently visualized on the LCD.
