1.Introduction
This instruction replaces the part (3)Message Format of section 125 MODIFICATION (CHG) of edition 18.0 of the IFPS Users Manual.
2.Update (changes are highlighted in yellow)
(3) Message Format
All modification messages (CHG) submitted to the IFPS for processing shall contain an opening bracket, the message title, aircraft identification, departure aerodrome and estimated off-block time, arrival aerodrome, a correctly formatted Item 18, Item 22 containing the content of the change and a close bracket.
For the IFPS the preferred option for the Item 18 is the insertion of the DOF as it can be used for association purposes.
Each item submitted in a modification message to update existing data shall be prefixed by a hyphen and the item number for that item. Any number of items may be updated in a single modification message.
In case of update of any Item 18 sub-field via Item 22, the whole Item 18 shall be inserted in the change message including the intended change as the IFPS completely overwrites the previous Item 18 content.
Example
Original flight plan held by the IFPS:
(FPL-ABC345-IG
-MD90/M-SRGWY/S
-EGLL1200
-N0430F330 BPK M185 CLN UL620 ARTOV UP44 SOMVA UP155 ANDIK UN873 JUIST UP729 DOSUR P729 TUDLO
-EKCH0130
- PBN/B2 DOF/121126 REG/GBAWC RMK/FERRY FLIGHT)
Messages submitted to the IFPS for processing for a change of aircraft type and registration and equipment:
(CHG-ABC345-EGLL1200-EKCH-DOF/121126-9/A321/M-10/ SRDGIWY/S-18/ PBN/B1 DOF/121126 REG/GBHTC RMK/FERRY FLIGHT)
Note‘DOF/121126’ represents the correctly formatted Item 18 and the Item 18 from the stored flight plan is completely repeated inside the item 22 and contains the change of aircraft registration and change of PBN.
NoteWhen updating certain items of a flight plan, it is necessary to consider any impact on other Items in that flight plan. For example, where an aircraft type and the requested cruising flight level are updated, the equipment and PBN of that new aircraft should also be replaced, as should the registration (where filed), and any route amendments resulting from the revised cruising flight level should also be included in a new route description.
NoteWhen sending modification messages in ADEXP format i.e. via an ICHG, it is not possible to update the EOBT as the EOBT present in the ADEXP message is used to match to the existing flight plan and therefore cannot be processed as an update to the EOBT.
