CAUTION: 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 Garmin GDU 620 utilize
GPS as a precision electronic NAVigation AID (NAVAID). Therefore, as with
all NAVAIDs, information presented by the GDU 620 can be misused or
misinterpreted and, therefore, become unsafe.
CAUTION: The Garmin GDU 620 does not contain any user-serviceable
parts. Repairs should only be made by an authorized Garmin service center.
Unauthorized repairs or modifications could void both the warranty and
the pilot's authority to operate this device under FAA/FCC regulations.
CAUTION: The GDU 620 PFD and MFD displays use a lens coated with a
special anti-reflective coating that is very sensitive to skin oils, waxes, and
abrasive cleaners. CLEANERS CONTAINING AMMONIA WILL HARM THE
ANTI-REFLECTIVE COATING. It is very important to clean the lens using a
clean, lint-free cloth and an eyeglass lens cleaner that is specified as safe
for anti-reflective coatings.
CAUTION: FIS-B information is to be used for pilot planning
decisions and pilot near-term decisions focused on avoiding areas
of inclement weather that are beyond visual range or where poor
visibility precludes visual acquisition of inclement weather. FIS-B
weather and NAS status information may be used as follows:
- To p r o m o t e p i l o t a w a r e n e s s o f o w n s h i p l o c a t i o n
w i t h r e s p e c t t o r e p o r t e d w e a t h e r, i n c l u d i n g h a z a r d o u s
meteorological conditions, NAS status indicators, and enhance
pilot planning decisions and pilot near-term decision-making.
- To cue the pilot to communicate with the Air Traffic Control
controller, Flight Service Station specialist, operator dispatch, or
airline operations control center for general and mission critical
meteorological information, NAS status conditions, or both.
FIS-B information, including, weather information, NOTAMs, and TFR
areas, are intended for the sole purpose of assisting in long- and near-
term planning decision making. The system lacks sufficient resolution and
updating capability necessary for aerial maneuvering associated with
immediate decisions.
