Potential Pitfalls of in Cockpit Weather (ADS-B In) Boeing Employees’ Flying Club There is always a delay in obtaining radar data then transmitting it. The radar image can be up to 20 minutes old. ADS-B Weather only shows a radar overlay with no information about what altitude the rain is at You can still call Flight Service for in route weather updates Don’t rely on onboard weather to skirt the edge of a storm. Leave yourself a buffer of at LEAST 20 miles around thunderstorms Weather data ATC has available is limited. Speak up if their direction puts you in danger Avoiding bad weather is your responsibility, not ATC’s Make sure you are familiar with GPS and iPad weather and traffic operations so you are not distracted in the cockpit Video: https://www.youtube.com/watch?v=83uvKWJS2os
