BF: PIB Integration (CHM-344)

The Narrow Route PIB creation based on a flight plan is improved by introducing the following enhancements:

More information in the PIB header.

In case the Narrow Route PIB is based on FPL, the following information is added to the PIB Header:

1. FIR information with FL Range and Flight Rules (see below for more details) 2. Height limits with buffer (see below for more details)

3. Complete route from the field 15 of the FPL 4. Latest version of the FPL and the Slot message

The user can tick message type in Filter scree that includes the last Slot message to the PIB Header. It is possible to enable/disable the slot message display via Corporate Identity property.

Figure 5-48 PIB Header – Narrow Route

The flight level information from FPL is used for more detailed filtering during Narrow Route PIB creation.

1. FL Buffer

Filter tab of Narrow Route PIB contains a new option called “Buffer” for defining Flight Level buffer in consecutive standard ICAO flight levels. After entering a value (between 0 and 9) and clicking Apply, the level information in the FIR list is re-calculated considering the actual ‘Buffer’ field value. Default FL buffer value is set to 2 and it is configurable per organisation via CI property.

Figure 5-49 CI – Default value of FL Buffer

FL Buffer is defined as number of consecutive standard ICAO flight levels above and below the flight level defined in FPL route. For the calculation INO DU shall use ICAO Table of Cruising Levels.

Example:

For FL 94 defined for VFR part of flight, the system first selects FL 95. Then FL 75 is used for lower height limit and FL 115 for upper height limit.

For FL 180 defined for IFR part of flight, the system selects FL 160 for lower height limit and FL 200 for upper height limit.

The vertical filter is calculated and applied separately for each “en-route” FIR of the associated flight plan. It is calculated as lower and upper height limit according to the flight level and flight rule changes defined in field 15, taking into account +/- value of FL Buffer. Vertical buffer for each FIR shall be calculated differently for IFR, VFR and mixed (IFR/VFR) flights:

IFR

First FIR: lower = 000

upper = max. FL in FIR + FL Buffer Middle FIR: lower = min FL in FIR – FL Buffer

upper = max. FL in FIR + FL Buffer Last FIR: lower = 000

upper = max. FL in FIR + FL Buffer

VFR

In case flight levels for a VFR flight are not defined in field 15, the option “All” is pre-selected with default values 000/140, which can be updated by user.

In case exact flight levels for VFR flights are defined in field 15, the system follows the same algorithm as for an IFR flight (described above).

Mixed (IFR/VFR)

The algorithm follows IFR rules for IFR part of the route and only NOTAM issued for IFR flights are included and it shall follow VFR rules for VFR part of the route and only NOTAM issued for VFR flights are included. For FIR where flight rules are changing from VFR to IFR or from IFR to VFR, the lower limit shall be set to 000 and upper limit to the highest FL in the FIR + FL buffer.

2. List of FIRs is enhanced with two additional columns:

 FL Range: Lower and Upper FL limit (e.g. 210-450)

 Flight Rules: IFR, VFR, IFR-VFR or VFR-IFR

En-route” FIRs displayed in the list are displayed with FL Range and Flight Rule values calculated for the associated FPL and with FL Buffer value. FIRs, which are added to the list manually, have FL limit values 000-999 and flight rules IFR-VFR by default.

It is possible do change FL Range limits manually for every FIR displayed in the FIR list. The FIR section in the PIB header includes also all the new information.

3. Updates to PIB validity period

Narrow Route PIB that is associated with a FPL (dynamically or manually created) will have the default start of validity equal to EOBT of the FPL.

The default PIB end of validity is automatically set to EOBT + ETA + configurable amount of hours (default value 3 hours). The amount of hours is configurable per organization via the CI property application (in range 0 – 22 hours).

Figure 5-51 CI – PIB end validity offset

In case a flight has been delayed and PIB distribution before EOBT has been activated, the time of distribution and the PIB validity are adopted accordingly.

Validity period of an update PIB respects the EOBT of FPL associated with the original PIB. “From:” time shall be EOBT (latest version of flight plan). If EOBT has already passed, it shall be the current time of update PIB generation. “To:” time shall be set to EOBT (latest version of flight plan) + ETA + configurable amount of hours.

The following default values are used for Narrow Route PIB in case the PIB is created without using the PIB dialog (e.g. directly from FPL list or dynamically activated PIB):

 Start of validity: equal to EOBT in FPL

 End of validity: EOBT + ETA + configured amount of hours

 FL Buffer: +/- 2 FL in case of IFR and mixed (IFR/VFR) FPL or VFR flights where given exact flight level in the field 15

 “All” Flight Levels (000/140) in case of VFR flights where there is not given exact flight level

 FPL message included in PIB

 SLOT message included in PIB (if enabled by configuration)
