5.6 Other Console Features

The following section describes additional console features.

5.6.1 Weather Forecasting

Note: The weather forecast or pressure tendency is based on the rate of change of barometric

pressure. In general, when the pressure increases, the weather improves (sunny to partly cloudy) and

when the pressure decreases, the weather degrades (cloudy to rain).

The weather forecast is an estimation or generalization of weather changes in the next 24 to 48 hours,

and varies from location to location. The tendency is simply a tool for projecting weather conditions

and is never to be relied upon as an accurate method to predict the weather.

5.6.2 Weather Icons

Sunny

Partly Cloudy

Cloudy

Rainy

The four weather icons are Sunny, Partly Cloudy, Cloudy and Rainy. There are also two weather

tendency indicators to show the air pressure tendency between the weather icons.

5.6.3 Weather tendency indicator

The weather tendency arrow is located between the weather icons to show the air pressure tendency

and provide a forecast based on increasing or decreasing air pressure.

The arrow pointing to the right indicates that the air pressure is increasing and the weather is expected

to improve. The arrow pointing the left indicates that the air pressure is decreasing and the weather is

expected to deteriorate.

The weather tendency is based on the pressure change since last six hours. If the weather is changing,

the weather tendency indicator (animated arrows) will flash for three hours, indicating the weather is

expected to change. If the weather conditions become stable and no new weather change conditions

are met, then the arrows will be fixed.

Example 1: Pressure is decreasing, weather is deteriorating.

Example 2: Pressure is increasing, weather is improving.
