空客关于SDAC的最新维护提示

太有才了 · 发表于 2013-7-5 15:25:33

针对件号SDAC PN 350E550020x的维护提示
可以参考TFU 31.54.00.003

最近一些A320运营公司反映在巡航过程中触发液压系统储压器超温等琥珀色虚假信息
空客建议确认安装件号后可以免费送修。

常见虚假信息为

‘HYD B(G)(Y) RSVR OVHT’ amber ECAM cautions with associated spurious hydraulic temperature indications on the “HYD” system page

- On the “HYD” system page, wrong PTU transfer indications, fluctuation of the hydraulic pressures, display of amber “OVHT” indication

- On the “ELEC” system page, fluctuation of TR voltage and Amps indications

- On the “DOOR” system page, pulsing “PAX OXY” indication, wrong oxygen pressure indication, fluctuation of the oxygen pressure display from green to amber, half box display

- On the “ENGINE” system page, fluctuation of the oil pressure and quantity indications

The following cockpit effects may also be triggered in case additional systems have failed on aircraft:
Spurious display of CAB PR OFV NOT OPEN amber ECAM caution on ground and wrong outflow valve display on the “CAB PRESS” system page
On the “BLEED” system page, wrong pack flow indication
On the “CAB PRESS” and “CRUISE” pages, wrong cabin differential pressure indication, wrong CAB ALT indication, wrong vertical speed indication: fluctuation of the needle display from amber to green, spurious advisory

有才哥想问个关于电源面板的问题 35VU上有个COMMERICAL这个按钮有什么作用一般用来干什么的

电源面板 35VU上的COMMERICAL按钮作用是：取消警告的语音提示，但相应的灯光信息仍然显示，在任何阶段皆可使用该按钮，取消后琥珀色警告信息可在状态页面调出，长按RCL按钮3s可取消该功能。

DESCRIPTION :Some A320 operators equipped with System Data Acquisition concentrator (SDAC) H2 units PN 350E550020x, havereported the intermittent triggering of two or three hydraulic overheat amber ECAM cautions during the same flight.Troubleshooting carried out by operators did not reveal any issue on the aircarft hydraulic system.CONSEQUENCE :In flight, crew may initiate a diversion or an In Flight Turn Back (IFTB).INVESTIGATION STATUS :SDAC H2 units are mainly composed of the following hardware parts:- a CPU board- a power supply board- a wired assembly- an input board- an INCONV board- an ANARINC boardThe ANARINC board acquires several types of analogical signals and converts them into ARINC information sent to severalaircraft systems.Investigations carried out by the vendor enabled to highlight a bonding issue on a batch of amplifier fitted on the ANARINCboard. This component is part of the analogical signals acquisition chain. The erratic behaviour of this amplifier could affectintermittently or permanently the acquisition of the analogical signals by the SDAC. Erroneous ARINC information could thenbe sent by the SDAC to various aircraft systems, which may result in the spurious triggering of one or several cockpiteffects:- Triggering of the HYD B(G)(Y) RSVR OVHT amber ECAM cautions with associated spurious hydraulic temperatureindications on the HYD system page- On the HYD system page, wrong PTU transfer indications, fluctuation of the hydraulic pressures, display of amber OVHTindication- On the ELEC system page, fluctuation of TR voltage and Amps indications- On the DOOR system page, pulsing PAX OXY indication, wrong oxygen pressure indication, fluctuation of the oxygenpressure display from green to amber, half box display- On the ENGINE system page, fluctuation of the oil pressure and quantity indicationsThe following cockpit effects may also be triggered provided additional systems are failed on aircraft:- Spurious display of CAB PR OFV NOT OPEN amber ECAM caution on ground and wrong outflow valve display on theCAB PRESS system page
