Standby ADI The HSI and MFD can be
configured as a “Standby”
instrument to preserve the display of
primary flight data in the event the
primary ADI fails or the pilot
reverts the display either through the
rotation of the outer knob counter-
clockwise or engages the
reversionary switch. An ADI page
will be available during both normal
operation and when reverted to
preserve the display of primary
flight data.
A stand-alone ADI may also be
considered a Standby ADI since it
provides full-time display of
primary flight data.
