When the FMs are in independent or single operation, each FM prints independently.

 D. ACARS Programming Options There are two levels of programming options available for the ACARS and printer functions:
 -through the Nav data base policy file, the airline may define the ACARS messages to be downlinked or uplinked, various automatic print functions associated with the datalinks which may be enabled or
R disabled and default settings or selection
 -through designated FM pages, the crew may select the messages or R reports to be printed automatically (as well as manually) and modify R the default settings or selection.
 The statuses of the ACARS functions are not modifiable from the dedicated ACARS FUNCTION page. From this page, the pilot may also initiate several ACARS functions. The selection of the uplink messages and/or reports to be printed automatically and manually is performed through a dedicated PRINT FUNCTION page.
 (1) Nav data base policy file Option programming for the ACARS and printer functions is obtained through a Nav data base policy file. This file contains parameters and options defined by the airline to allow customization of FM functions such as allowing an airline to enable or disable various functions or facets of a function within the FM and to change the selected options on data base updates. The ACARS and print options described within this section only define the selectable ACARS and print options used within the FM and are a subset of the parameters within this file.
R  The programming of the function is applied at initial power-up. Some
R  of the options are pilot modifiable. If this file is not present, then all of the ACARS functions are inhibited. This section summarizes all of the options that are contained within the Nav data base policy file related to the ACARS and printer functions.
 (a) Option/Function
 1 Data Link (ACARS):
_ This option determines whether or not any ACARS functions are to be utilized. It is supplemental to the ACARS installed program pin discrete input and can be used to disable the ACARS function if it is installed.
 2 Flight Plan Data (FPN) request inhibit:
_ This option determines whether or not the uplink data and downlink requests of flight plan initialization data are allowed.

 NOTE : Performance data datalinks are not controlled by this
____
 option.

 3 Performance Data (PER) Request inhibit:
_
 This option determines whether or not the uplink data and
 downlink requests of performance initialization data are
 allowed.

 4 Takeoff Data (LDI) Request inhibit:
_ This option determines whether or not the uplink data and downlink requests of takeoff initialization data are allowed.
 5 Wind Data (PWI) Request inhibit:
_
 This option determines whether or not the uplink data and
 downlink requests of predicted wind data are allowed.

 6 Flight Number IEI Enable:
_
 This option determines whether or not the flight number is
 included within the flight plan request or progress report
 downlink messages.

 7 Ground Address (GA) Enable:
_
 This option determines whether or not one or more ground
 addresses are allowed within downlink messages.

 8 Datalink Ground Addresses:
_ This element defines a list of ground addresses per designated IMIs to which a ground address is appended for a downlink message transmission.
 9 Company Address (CA) Enable:
_
 This option determines whether or not a company address is
 allowed within downlink messages.

 10 Datalink Company Addresses:
__ This element defines a list of company addresses per designated IMIs to which a company address is appended for a downlink message transmission.
 11 Time Stamp (TS) Enable:
__ This option determines whether or not a Time Stamp element is transmitted for any downlink message.
 12 Scratchpad (SP) Enable:
__ This option determines whether or not a "Scratch Pad" element is transmitted for manually initiated downlink message.

 13 Position (POS) Report inhibit:
__ This element defines whether or not a position report can be manually downlinked.
 14 Data Link PRG Report Triggers:
__ This element defines the report triggers for the automatic transmission of the progress report. The report triggers are:
 -
minutes to Top of Descent Triggers (0 to 5 triggers of number of minutes to T/D)

 -
minutes to Destination Triggers (0 to 5 triggers of number of minutes to destination)

 -Delta ETA Trigger
 15 Flight Plan (FPN/FPC) Report inhibit:
