Piyawut Tantimekabut (Toon)Chair, ICAO APAC ATFM/SG

ICAO MID ATFM/TF/312– 14 Jan 2020Amman, Jordan

PANS-ATM Provisions on DEP Messages

12-14 Jan 2020 Non-Receipt of DEP Messages 2

• Activate flight plans in ATS automation systems

• ATFM demand prediction and monitoring

• ATFM Post-Ops Analysis

• Confirmation that a flight operated in order to levy air navigation charges

Use of DEP Messages

12-14 Jan 2020 Non-Receipt of DEP Messages 3

• Additional ATCO workload activating flights with no DEP messages => unnecessary reduction of airspace sector capacity => potential for error/distraction under high workload

• Inaccurate traffic demand prediction => inaccurate demand-capacity balance => inaccurate activation of ATFM Measure => unnecessary ATFM delays

• Additional workload / cost in confirming flight’s operation in collecting air navigation charges

Problems from Missing DEP Messages

12-14 Jan 2020 Non-Receipt of DEP Messages 4

• Operational procedures and automation configuration for originating DEP messages at departure aerodromes– Need to be reviewed at departure aerodromes– ATM system configuration – use fixed addressee list per city

pair instead of FPL content analysis (message address line, Item 15 – route details, and/or Item 18 – EET)

• Non-standard FPL & ATS messages addressing requirements vis-à-vis PANS-ATM 11.2.1.2.3.3– ICAO Standard-Compliant Example: VTBBZQZX

• Incomplete listing of FIR Boundary EET in FPL Messages– May be addressed with AIP / Doc 7030

Monthly Non-Receipt of DEP Messages (UAE)

• ICAO MID States to review operational procedure / automation configuration in originating FPL and DEP messages and resolve non-receipt of these messages– Includes procedure to originate DEP, addressee list in case ATM automation

system is configured to send DEP messages to fixed addressee list instead of FPL analysis

– Data from ICAO APAC ATM/SG WP and detailed data for Dec 2019 provided by Thailand can be starting point

• ICAO MID States consider releasing AIP Amendment requiring inclusion of all FIR Boundary EETs in Item 18 of FPLs or consider PfA to Doc 7030 requiring so– May be used to alleviate missing DEP messages for overflights– Early dynamic trajectory update for ATFM demand calculation

• ICAO MID States to review FPL & ATS message addressing requirement and ensure compliance with ICAO PANS-ATM 11.2.1.2.3.3 and 11.4.2.2.3 to 11.4.2.2.6, (especially 11.4.2.2.6.2, for DEP)

• Ensures that addressee list can be correctly simplified into [loc_ind]ZQZX• (location indicator of centre in charge of the FIR)
