Hazard Avoidance
Temporary Flight Restrictions (TFR)
WARNING: Do not rely solely upon datalink services to provide Temporary Flight
Restriction (TFR) information. Always confirm TFR information through official sources
such as Flight Service Stations or Air Traffic Control.
Temporary Flight Restrictions (TFRs) temporarily restrict all aircraft from entering the
selected airspace unless a waiver has been issued. TFRs are routinely issued for activities such
as sporting events, dignitary visits, military depots, and forest fires. TFRs are represented as
an area outlined in yellow.

NEXRAD
NEXRAD (NEXt-generation RADar) is a network of multiple high-resolution Doppler
radar sites that are operated by the National Weather Service (NWS). NEXRAD data provides
centralized meteorological information for the continental United States and selected overseas
locations. The maximum range of a single NEXRAD radar site is 250 nm. In addition to a wide
array of services, the NEXRAD network provides important information about severe weather
and air traffic safety. NEXRAD data is not real-time. The lapsed time between collection,
processing, and dissemination of NEXRAD images can be significant and may not reflect the
current radar synopsis.
Composite NEXRAD data is composed of the maximum reflectivity from the individual
radar sweeps. The display of the information is color-coded to indicate the weather severity
level.
