Activation of the remote Category
II switch by the pilot will cause a
yellow CAT II to be displayed on
the ADI and HSI to indicate that
Category II annunciations are
active. The remote Category II
selection switch will be a momen-
tary contact type for software 06
and 0701, but must be alternate
action for software 0702 and 08
(or later). Category II can be
activated at any time and in all
normal modes of the EFS.
In the normal sequence of
events, a white CAT II will be dis-
played on the ADI and HSI in
place of the previous yellow CAT
II only when certain criteria are
met:
The following requirements must
be met in a four or five tube EFS
system before the Category II
annunciator will change to white:
1. Valid ILS or MLS #1 is select-
ed on Symbol Generator #1.
2. Valid ILS #2 is selected on
Symbol Generator #2.
3. Valid ATT #1 is selected on
Symbol Generator #1.
4. Valid ATT #2 is selected on
Symbol Generator #2.
5. Valid HDG #1 is selected on

6. Valid HDG #2 is selected on
Symbol Generator #2.
7. Pilot and copilot symbol gen-
