WARNING:

  For safety reasons, this AOA System’s operational 

procedures must be learned on the ground. 

 

CAUTION

:  This AOA System 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 
regulations. 

 

NOTE

:  All visual depictions contained within this document, including 

screen images of the GI 260 displays, are subject to change and may 
not reflect the most current GI 260 software. Depictions of equipment 
may differ slightly from the actual equipment. 

 

NOTE

:  This product, its packaging, and its Components contain 

chemicals known to the State of California to cause cancer, birth 
defects, or reproductive harm. This notice is being provided in 
accordance with California’s Proposition 65. If you have any questions 
or would like additional information, please refer to our web site at

NOTE

:   This AOA System is non-required and is to be used only as 

supplemental information to the pilot.  This AOA System is not to be 
used or substituted for a certified stall warning system.  No operational 
credit may be taken for reduced approach speed and shorted landing 
distances.

 

NOTE

:  The approved Pilot’s Operating Handbook (POH) or Airplane 

Flight Manual (AFM) always supersedes this Owner’s Manual.

 

NOTE

:  Refer to the AOA System Installation Manual for calibration 

instructions.

 

NOTE

:  This AOA system is designed to be accurate in the calibrated 

aerodynamic configuration.  When the aircraft experiences changes in 
the airfoil shape (e.g., flap extension or icing accumulation), the AOA 
indicator may no longer accurately represent the angle of attack.
