Obtaining Weather Info Flashcards
What service does the FAA provide to pilots to obtain a briefing?
Flight Service program 1.800.wxbrief and online 1800wxbrief.com also Flight Service Stations (FSS) in the air
Two main categories of sources of weather data?
Federal - FAA and NWS
commercial - basically take info from FAA/NWS and repackage it
Does using weather info from commercial providers as opposed to federal info satisfy the preflight action required by 91.103?
Neither yes or no. FAA says just be aware that it may not meet FAA/NWS quality control standards. When in doubt, contact FSS!
What types of weather briefing services are available with FSS?
