An  AIRMET (AIRman’s METeorological Information) can potentially affect all aircraft. This data can be especially helpful for 

pilots of light aircraft that have limited flight capability or instrumentation. An AIRMET must affect or be forecast to affect an area 

of at least 3,000 square miles at any one time. AIRMETs are routinely issued for 6 hour periods and are amended as necessary due 

to changing weather conditions or issuance/cancellation of a SIGMET. AIRMETs are displayed as a colored dashed line. To view 

AIRMET data, select the AIRMET using the map pointer. To view detailed information, press ENTER.
