Input of the reports
CAPE is used as data source of the reports.
The report includes all receptacles for which all the following conditions are met:
- the LHOT (or back-up target time) is in the past
- the LHOT (or back-up target time) is less than X days in the past (to avoid reporting old receptacles). X = 7 days (It has been agreed to approach simple, so the value is equal for all (i.e. 7 days), this can be reviewed and adjusted later once the alert is in place)
- none of the following messages is available at destination:
- MRD POD (Mail Registration Device Proof of Delivery) or MRD Scan File
- Any EMSEVT message at import stretch to an item of the receptacle (i.e EMD, EDA, EDB, EME, EDC, EMF, EDD, EDE, EMG, EDF, EDG, EDH, EMI and EMH)
Based on the agreed “point of hand over” between Leg 2 and Leg 3 in the Interconnect Operations Framework Agreement (IOFA) RESDIT21 should also be taken into consideration (as 2nd priority after the MRD POD). As this report is an alert report it is decided not to consider RESDIT21 as it may raise discussions if the inbound operator has “taken control”.
- Only if the number of affected receptacles is greater than 5 percent of the total number of receptacles per flow that has been sent since X days ago (being X the number of days defined on the second bullet point) (It has been agreed on a unique percentage for all (i.e. 5 %) and this can be reviewed and adjusted later when we see the outcome of the report).
For the origin perspective, the receptacles must also be:
- From the origin post
- To a defined list of destination posts (or all), to be defined by every Postal Operator
- The mail category is A (Air Priority) mail
- For specific subclasses (or all), to be defined by every Postal Operator
For the destination perspective, the receptacles are:
- To the destination post
- From a defined list of origin posts (or all), to be defined by every Postal Operator
- The mail category is A (Air Priority) or B (S.A.L [Surface Air Lifted mail])
- For specific classes/subclasses (or all), to be defined by every Postal Operator.
Back-up target times for the LHOT
By only using the LHOT value from the CARDIT message, the report is ignoring many receptacles.
To avoid this issue, the report is using as target time the first not null value from the following list:
- LHOT from the latest CARDIT message (i.e codes 47, 9, 5 or 6)
- Scheduled time of arrival of last leg transport from the CARDIT message + offset specific to the destination airport
- Scheduled time of arrival of last leg transport from the PRECON message + offset specific to the destination airport
- Scheduled time of arrival of last leg transport from the PREDES message + offset specific to the destination airport
- Latest arrival time maintained by IPC + offset to the destination airport
The offset from point 2 to 5 is available in the CAPE database. It is defaulted to 2 hours for all destinations. For some locations, it has been adapted based on inputs received over the years by ground handlers, local posts, etc.
