FIS-B does not replace a preflight weather briefing
from a source listed in Paragraph 7

Weather Services, or inflight updates from an FSS or
ATC. FIS-B information may be used by the pilot for
the safe conduct of flight and aircraft movement;
however, the information should not be the only
source of weather or aeronautical information. A
pilot should be particularly alert and understand the
limitations and quality assurance issues associated
with individual products. This includes graphical
representation of next generation weather radar
(NEXRAD) imagery and Notices to Airmen
(NOTAM)/temporary flight restrictions (TFR).

Users of FIS
−
B can provide valuable assistance in the
correction of malfunctions by reporting instances of
undesirable system performance. Since FIS

B
performance is monitored by maintenance personnel
rather than ATC, report malfunctions to the nearest
Flight Service Station (FSS) facility by radio or
telephone. Reporters should identify:
1.
Condition observed.
2.
Date and time of observation.
3.
Altitude and location of observation.
4.
Type and call sign of the aircraft.
5.
Type and software version of avionics
system.
