1.2 UNIT TYPES AND CONFIGURATIONS

UNIT TYPES

Basic
The basic model of the MFI can act as an attitude indicator (ADI), horizontal situation
indicator (HSI), engine indication system (EIS), or multi-function display (MFD).
To act as an attitude indicator, the basic MFI must have an external AHRS source. To display
air data, the basic MFI must have an external air data computer. To show magnetic heading,
all MFIs must have an external magnetometer.
