Section 9
Supplements
Section 1 - General
The airplane is equipped with the Garmin Terrain Awareness/Warning
System that performs the functions of a Class C Terrain Awareness
and Warning System (TAWS) in accordance with TSO C151b.
Refer to the Cirrus Perspective Integrated Flight Deck Pilot's Guide for
a additional information on the system and its operating modes.
Section 2 - Limitations
1. Do not use Terrain Awareness and Warning System for navigation
of the aircraft. The TAWS is intended to serve as a situational
awareness tool only and may not provide the accuracy fidelity on
which to solely base terrain or obstacle avoidance maneuvering
decisions.
2. To avoid getting unwanted alerts, TAWS must be inhibited when
landing at an airport that is not included in the airport database.
Only vertical maneuvers are recommended responses to
warnings and cautions unless operating in VMC or the pilot
determines, using all available information and instruments,
that a turn, in addition to the vertical escape maneuver, is the
safest course of action. During certain operations, warning
thresholds may be exceeded due to specific terrain or
operating procedures. During day VFR flight, these warnings
may be considered as cautionary.
Pilots are authorized to deviate from their current air traffic
control (ATC) clearance to the extent necessary to comply
with a TAWS warning.
