CONF ALL B. REASON
(1) History This Service Bulletin has been issued in order to introduce the FMGC 3G H4PC20 on A319/A320/A321 NEO aircraft equipped with CFM engines.
This new FMGC standard introduces some safety enhancements that are part of the AIRBUS safety beyond standard step1 project, refer to Ref. ISI 22.00.00104.
(2) Objective/Action The modification consists in installing the new FMGC 3G STD H4PC20 in place of FMGC 3G STD H3PC19 and H3PC20 on aircraft equipped with CFM engines.
This modification is an evolution of both FG and FM software.
(3) Advantages Accomplishment of this Service Bulletin will bring the following improvements:
(a) On FG side, in comparison to FG standard PC19, the FG standard PC20 provides the following improvements:
- For A319 NEO CFM only:
- FG PC20 is the minimum standard for CAT2/CAT3 Automatic Landing (AUTOLAND) on A319 NEO CFM. The removal of the AUTOLAND limitation is activated through a separate Service Bulletin No. Ref. SB A320-22-1568 installing MOD No. 161765 on A319 NEO CFM
- T uning of FD at take-off to improve the A319 NEO CFM AFM takeoff performance. A pin prog activated by separate MP P21896 is applied in order to inhibit this function as long as the FD function is not certified, the MP P22054 will remove the pin prog P21896.
- For all A320 Family NEO aircraft:
- Improvement of Runway Overrun Prevention System (ROPS step 2+) by taking into account two new cockpit features:
A318/A319/A320/A321
SERVICE BULLETIN
SUMMARY REV 00 Nov 26/21 A320-22-1821 Page 4
- Dry/wet rotary selector to select runway condition in order to avoid "IF WET: RWY TOO SHORT" alert while landing on a dry runway
- "ROW/ROP" OFF push-button for ROPS deactivation. This function requires the MOD No. 163425P20473 and MOD No. 166357P21486 for activation
- Introduction of TCAP function capability, which allows to avoid unnecessary TCAS resolution advisories
- Introduction of SLS approach CAT 1 capability. This function is available with FMS H4 standard. This function requires the following MOD for activation: MOD 165088/MP P2119
- Improvement of AP/FD/ATHR functions availability in case of FMS and LGCIU failure
- Improvement of “LVR TOGA” message display logic by displaying the message also when thrust levers are set on maximum continuous thrust whereas neither “FLEX” nor “Derated TO” mode are selected at MCDU
- Introduction of smart exit alpha floor, when the aircraft is back into the normal flight envelope, the ATHR returns to its previous state.
TOGA thrust is no longer applied after alpha floor recovery
- Introduction of ATHR auto-engagement in overspeed situation to automatically reduce the airspeed. The pilot will be alerted of the automatic ATHR engagement through a flashing amber boxing of the SPEED (or MACH) mode on the FMA as long as the aircraft is in overspeed. The ATHR returns to its previous state when the aircraft is no more in overspeed
- Improvement of “TCAS MODE FAULT” message display logic. This improvement addresses the issue described in TFU 22.00.00.209
- Correction of a possible altitude constraint capture after GA
- Introduction of vertical speed target limitation near ground and ceiling to avoid inappropriate AP/FD orders at AP/FD engagement
- Introduction of FMGC hardware pin-prog display on MCDU Note: This function requires the installation of FAC minimum standard CAA12.
- Introduction of FMGC1/FMGC2 mixed FG software configuration check. In case of mixed FMGC configuration, a new amber ECAM caution `AUTO FLT FMGC VERSIONS DISAGREE', is displayed in Phase 1 (pre-flight on ground) Note: This function requires the installation of FWC minimum standard F13.
- Improvement of ADIRU failure isolation:
The existing PFR message "AFS:ADIRU 1/2/3 DISAGREE" is replaced by "AFS:ADIRU DISAGREE XX" message. XX corresponds to the failure code allowing to incriminate the rejected ADR or IR. This function also requires the installation of FAC minimum standard CAA13.
- Reduction of the longitudinal AP guidance authority in GA in order to avoid possible AP disconnection due to ELAC alpha protection. The modification cancels the Operations Engineering Bulletin (OEB)57 and addresses the issue described in TFU 22.10.00016.
- Correction of COM/MON discrepancy in case of GA during Flare. This modification addresses the issue described in FCOM A321N TAB DSC- 22_30-110 “DUAL FMGC RESET AFTER GO-AROUND CLOSE TO THE GROUND”.
(b) On FM side, in comparison to FM standard H3, the FM standard H4 provides the following main improvements:
A318/A319/A320/A321
SERVICE BULLETIN
SUMMARY REV 00 Nov 26/21 A320-22-1821 Page 5
- SLS function (new OPC option) activated through dedicated major MOD 165088/MP P21191. SLS is a precision approach procedure based on differential GPS position whose accuracy is improved thanks to the use of geostationary satellites (linked to SBAS function)
- SBAS navigation function (new OPC option) activated through dedicated MOD opened by MP P21606, allowing aircraft to use augmented GPS position and needed to fly SLS approaches (this capability requires minimum MMR standard)
- NDB cycle swap confirmation prompt, avoiding inadvertent NDB cycle swap with the consequence of dual loss of F-PLN
- Transmission of additional data to improve synthetic runway display on HUD
- Display of GPS data on MCDU upon IR fault: on GPS MONITOR page, GPS raw data are displayed as soon as received valid from ADIRS and kept displayed regardless of GPIRS validity status
- Improvement of tropopause and cruise temperature entry formats: the FMS is now able to recognize TROPO values defined in FL and to convert them into feet for display and predictions computation. For the temperature, the improvement consists in displaying the CRZ TEMP and GND TEMP values in INIT page always with their associated sign
- Improvement of approach legs sequencing rule in HDG/TRK: leg sequencing rules have been refined in order to avoid undue automatic sequencing of destination or flight plan waypoints in approach when flying in heading or track mode
- Improvement of below path predictions in approach
- Correction of descent transition level sign
- Differentiation of FM pages related to secondary flight plan.
(4) Operational/Maintenance Consequences The Operational/Maintenance Consequences of this Service Bulletin are covered by the update of the affected publications detailed in "PLANNING INFORMATION".
This Service Bulletin cancels Operations Engineering Bulletin No(s). 57. Operators having programmed an OEB reminder should delete the reminder(s) from their system.
This Service Bulletin has an impact on flight operations documentation; consult AirbusWorld and refer to Ref. MOI 163903 described in TFU 22.00.00102 and Ref. MOI 167616 described in TFU 22.00.00108.
