Help for Current WX

 

 

PURPOSE: The Current WX is used to view the current and recent weather for a given station.

When to Use the Current WX

To view consolidated weather data for the past 36 hours

The Current WX screen is used to view current weather data for a METAR station. In addition to the current data all available METAR history is plotted to show trends over the previous 36 hours.

To get a quick read on weather compared to minimums and maximums

This data is used before a flight to assess current conditions and weather trends along the route of flight. The METAR values are colored according to personal minimums and maximums. This brings important information to the pilots attention.

To help visualize conditions over time

Crosswind and Headwind components are displayed for up to three runways. This data is also color coded based on user selected limits.
