OOOI pages record data about the current flight and flight history. The
OOOI option is available (if configured) at LSK [3L] on the OPS 1/2
page.
OOOI Operation
OOOI (Out, Off, On, In) reports allow a dispatch or schedule office to
track a flight as well as provide accurate flight times and block times.
Based on installation, UniLink may use inputs from one or more doors,
the parking brake, and weight-on-wheels (WOW) status input. OOOI
reports may also use digital inputs from devices such as the FMS or
configured Input/Output Processors (IOP).
UniLink monitors the state of each discrete and the WOW condition at
power-up, but does not issue any reports unless a change in state is
detected. The OUT requirement is met when all doors are closed and
then the parking brake is released. The ideal sequence is:
1) UniLink powered up with brake set and doors open
2) Doors closed
3) Brake released
4) OUT report generated
Once the OUT report has been generated, if the door is opened prior
to takeoff, an OUT/RETURN IN report will be generated.
A change in the WOW status from on-ground to in-air will result in an
OFF report.
If UniLink is powered up or reset in flight, it will monitor the WOW
state, determine that the aircraft is airborne and ignore all changes in
status of doors and brakes. A change to the WOW status from in-air to
on-ground will result in the ON report.
For an IN report to be generated, UniLink must:
• detect an OUT transition
• detect an OFF transition
• detect an ON transition
• and then detect that the door is opened
