ICAO 2012 Network Operations Update Presented by Andy Woollin 10th October 2012

In April this year we entered transition mode, allowing either NEW or PRESENT flight plans.  We receive a small number of NEW flight plans, and are experiencing no operational problems.  3.3% (1000 out of 30,000) of the flight plans that we receive are flagged as “BOTH“, which are valid under NEW or PRESENT (OLD) rules. There are very few problems in IFPS with conflicting ‘OLD’ and ‘NEW’ fields in flight plan messages.

CHG message with partial Field 18 information IFPS replaces the complete stored Field 18 information with the Field 18 information contained in CHG messages. There are still some airlines that are sending partial Field 18 information in CHG messages and are potentially removing important information from the stored/distributed FPL. (FPL-ROT302-IS -A318/M-SDGHIPRWY/S -EDDF0950 -N0440F390 SULUS6S SULUS UZ650 BERVA UM748 TEGRI/N0440F330 UL605 LAMIT UL5 TUSET TUSET6E -LROP0225 -OPR/ROT DOF/120910 RVR/200 ORGN/RPL) (CHG-ROT302-EDDF0950-LROP-18/REG/YRASA) (CHG-ROT302-EDDF0950-LROP-18/REG/YRASA DOF/120910 ORGN/OTPFWRO)

AFP Messages in OLD format When an ANSP is receiving a translation service from IFPS after the 15th November, it is possible that their systems will automatically create ATC Flight Plan (AFP) messages in OLD format. If the ANSP system copies the field 10 information from the FPL and transmits that to IFPS, the AFP may raise an error in the IFPS system. Where possible, ANSPs need to provide basic field 10 (in AFTN format messages) to IFPS.

Switch Contingency/Mitigation To reduce the number of ‘OLD’ format flight plans with a DOF after the switch date, the acceptable DOF for filing to IFPS will decrease from 120 hours to 24 hours, and then back to 120 hours after the switch. 96h 15 Nov 120h 14 Nov 13 Nov 72h 48h 24h 11 Nov 12 Nov 10 Nov New Only During the period around the date of the switch, IFPS Staffing will be increased. On the night of the default ready date switch, there will be cover provided for urgent environment data updates.

Switch Contingency/Mitigation The IFPS has a systematic rejection feature that will be used if certain types of repetitive error risk overloading the IFPS manual processing function. Examples: Reject all FPLs received from address XXXXXXX when EFPM166 error raised. Reject all FPLs received when SYN94 error raised. This option needs to be used with caution as it may result in an increase of telephone queries.

Switch Contingency/Mitigation Standard management of IFPS invalid message queue. Maximise the number of active positions Establish working positions dedicated to detect urgent messages Establish working positions dedicated to take incoming telephone calls Remote log-in from other IFPS Unit. Load Shedding

Switch Contingency/Mitigation As a last resort… A modification of the invalid FPLs to include only the basic equipment necessary in Field 10 (SRGWY/C) and PBN (B2) to comply with EUR 833, RVSM and RNAV requirements. This may result in other data being removed, if it is the source of the error. If this procedure is to be implemented a priority order of FPLs to be targeted should be established e.g. starting with internal European FPLs before long haul FPLs. An AIM would be issued if this measure was needed.

AIM and NOP Headline News During November, AIMs and the Network Operations Portal (NOP) Headline News will be heavily utilised to get the FPL 2012 message out.
