Eliminate noise on 26 Vac output.
Mod 1 prevents possible degradation of flag relay contacts, which may result in improper or intermittent flag
operation. Mod 2 prevents possible degradation of back course engage relay contacts, which may result
when switching from back course mode annunc
Mod 3 prevents a possible short circuit condition between Meter Switching Circuit Card Assembly (A8) power
ground and housing and plate assembly, which may cause undesirable chassis ground connections.
Mod 5 prevents possible intermittent flags due to over voltage conditions at the input to the attitude
indicator.
Mod 4 prevents possible failure of the ILS function switch and bracket assembly because of switch damage
or shaft separation, which is normally caused by excessive force on the ILS function knob during ILS mode
selection.
