Prior to every flight, pilots should gather all information vital to the nature of the flight. This site is informational in nature and is designed to assist pilots and aircrews for flight planning and weather familiarization. It may be used in conjunction with other preflight information sources needed to satisfy all the requirements of 14 CFR 91.103 and is not to be considered as a sole source of information to meet all preflight action. Pilots can complete their regulatory-compliant preflight briefing by using other automated resources or from Flight Service at www.1800wxbrief.com or by calling 1-800-WX-BRIEF.
