Refer to Figure 7.2,
EADI DOWN MODE
SELECTION.
DISPLAY (ADI) DOWN mode
selection is generally used to
compensate for a failure of the
EADI display unit or section of
the symbol generator. Available
for use in two, three, four and
five-tube installations. The DIS-
PLAY DOWN mode will allow the
pilot or copilot to transfer the nor-
mal EADI display to the EHSI
below the failed EADI and trans-
fer the EHSI display to the MFD if
one is installed. A single
momentary switch input removes
power from the failed EADI,
transfers the EFIS control panel
control to the MFD symbol gener-
ator, instructs the EHSI symbol
section to calculate EADI func-
tion and the MFD symbol genera-
tor to calculate matching EHSI
functions.
