System Overview 

1.1 

System Description 

The Astronautics Flight Instrument (AFI) 4700 is a 5” by 7” Electronic 
Flight Instrument (EFI) designed to replace and improve upon the 
legacy electromechanical Attitude Director Indicator (ADI) and 
Horizontal Situation Indicator (HSI). 

 

Figure 1-1: System Description 

The AFI4700 is designed to interface with existing and/or retrofit 
attitude and heading units, navigation radios, GPS systems, etc.  A list 
of compatible equipment is found in the installation manual. 

The EFI is capable of displaying several HSI overlays to consolidate 
situational awareness information normally available in different 
locations in the instrument panel to the AFI4700.
