Warnings, Cautions & notes
WARNING: NEXRAD weather data is to be used for long-range planning
purposes only. Due to inherent delays in data transmission and the relative
age of the data, NEXRAD weather data should not be used for short-range
weather avoidance.
®
WARNING: The Perspective
system, as installed in the Cirrus SR20/SR22
aircraft, has a very high degree of functional integrity. However, the pilot
must recognize that providing monitoring and/or self-test capability for all
conceivable system failures is not practical. Although unlikely, it may be
possible for erroneous operation to occur without a fault indication shown by
®
the Perspective system. It is thus the responsibility of the pilot to detect such
an occurrence by means of cross-checking with all redundant or correlated
information available in the cockpit.
®
WARNING: For safety reasons, Perspective system operational procedures
must be learned on the ground.
WARNING: The United States government operates the Global Positioning
System and is solely responsible for its accuracy and maintenance. The GPS
system is subject to changes which could affect the accuracy and performance
®
of all GPS equipment. Portions of the Perspective system utilize GPS as
a precision electronic NAVigation AID (NAVAID). Therefore, as with all
®
NAVAIDs, information presented by the Perspective system can be misused
or misinterpreted and, therefore, become unsafe.
WARNING: To reduce the risk of unsafe operation, carefully review and
®
understand all aspects of the Perspective Pilot's Guide documentation and
the Cirrus SR20/SR22 Airplane Flight Manual. Thoroughly practice basic
operation prior to actual use. During flight operations, carefully compare
indications from the Perspective ® system to all available navigation sources,
including the information from other NAVAIDs, visual sightings, charts, etc.
For safety purposes, always resolve any discrepancies before continuing
navigation.
WARNING: The illustrations in this guide are only examples. Never use the
Perspective system to attempt to penetrate a thunderstorm. Both the FAA
®
Advisory Circular, Subject: Thunderstorms, and the Aeronautical Information
Manual (AIM) recommend avoiding "by at least 20 miles any thunderstorm
identified as severe or giving an intense radar echo."
