Call flight Service on 122.2 for routine weather, current reports on hazardous weather, and altimeter settings
What service should a pilot normally expect from Flight Service?
Actual weather information and thunderstorm activity along the route
En route weather advisories should be obtained from an FSS on
122.2 MHz
How could you receive in-flight weather information about your destination while still 150 NM away?
Review the destination METAR and TAF through FIS-B
