空客A340-600简介
空中客车A340-600飞机性能简介一、机型简介A340和A330是欧洲空中客车工业公司在分析世界主要航空公司90年代需求后，于1986年1月宣布研制的两种先进双过道宽机身客机。
除了发动机的数量和与发动机相关的系统外，这两种机型有很大的共同性，采用同样的机身，只是长度不同，驾驶舱、机翼、尾翼、起落架及各种系统都相同，这样可以降低研制费用。
A330/A340系列的概念非常独特：一个基本的机身可以提供6种不同的构型，以2台或4台发动机作为动力装置。
A330/A340采用空中客车独特的222英寸机身横截面，为所有级别客舱的乘客提供最高水准的舒适性。
大的底舱空间适于放入集装箱或货盘，其中包括业界标准的LD-3集装箱。
1987年4月欧洲客车工业公司决定A330和A340两个型号作为一个计划同时上马。
A330和A340两个型号的研制费共计25亿美元（1986年币值）。
我公司即将引进的A340-600型飞机为远程型。
座位布局为8个头等舱，60个商务舱，220个经济舱。

EquipmentThe LM4040series of shunt voltage references are versatile,easy-to-use references that cater to a vast array of applications.The2-pin fixed-output device requires no external capacitors for operation and is stable with all capacitive loads.Additionally,the reference offers low dynamic impedance,low noise,and low temperature coefficient to ensure a stable output voltage over a wide range of operating currents and temperatures.The LM4040uses fuse and Zener-zap reverse breakdown voltage trim during wafer sort to offer four output voltage tolerances,ranging from0.1%(max)for the A grade to1%(max)for the D grade.Thus,a great deal of flexibility is offered to designers in choosing the best cost-to-performance ratio for their applications.Packaged in space-saving SC-70and SOT-23-3packages and requiring a minimum current of45µA(typ),the LM4040also is ideal for portable applications.The LM4040xI is characterized for operation over an ambient temperature range of–40°C to85°C.The LM4040xQ is characterized for operation over an ambient temperature range of–40°C to125°C.Please be aware that an important notice concerning availability,standard warranty,and use in

SupplyLM4040PRECISION MICROPOWER SHUNT VOLTAGE REFERENCESLOS456J–JANUARY 2005–REVISED SEPTEMBER 2006Figure 7.Test CircuitThe LM4040does not require an output capacitor across cathode and anode for stability.However,if an output bypass capacitor is desired,the LM4040is designed to be stable with all capacitive loads.There is a parasitic Schottky diode connected between pins 2and 3of the SOT-23packaged device.Thus,pin 3of the SOT-23package must be left floating or connected to pin 2.The LM4040x-41is designed to be a cost-effective voltage reference as required in 12-bit data-acquisition systems.For 12-bit systems operating from 5-V supplies such as the ADS7842(see Figure 8),the LM4040x-41(4.096V)permits operation with an LSB of 1mV.Figure 8.Data-Acquisition Circuit

INFORMATION(continued)In a typical shunt-regulator configuration(see Figure9),an external resistor,R S,is connected between the supply and the cathode of the LM4040.R S must be set properly,as it sets the total current available to supply the load(I L)and bias the LM4040(I Z).In all cases,I Z must stay within a specified range for proper operation of the reference.Taking into consideration one extreme in the variation of the load and supply voltage(maximum I L and minimum V S),R S must be small enough to supply the minimum I Z required for operation of the regulator,as given by data-sheet parameters.At the other extreme,maximum V S and minimum I L,R S must be large enough to limit I Z to less than its maximum-rated value of15mA.R S is calculated according to Equation1:Figure9.Shunt

空中客车A340
动力设计
维珍航空的A340-600A340动力装置所选用的发动机有CFM56、和PW4000。发动机压缩比更高，加大了进气 道和进气量，提高了发动机推力，降低了燃油消耗。空中客车A340系列飞机通过技术削减飞机维护成本，降低了 飞机的重量并减少了燃油成本。该飞机配备四台发动机的布局可使航空公司有能力灵活制定远程和超远程航线计 划，用以补充已有的飞机系列。A340作为一款四发远程飞机不受双发延程飞行（ETOPS）的限制，包括当时最新 的宽体远程飞机－－波音767，由于必须尽可能靠近紧急转飞用机场，以应付其中一具发动机故障时的情况；四 发动机的波音747则没有类似的问题。空中客车将A340设计成四发动机飞机，就是为了研发一款不受ETOPS限制的 新一代飞机。1990年代，空中客车相信四发动机飞机，具有较大的安全程度，在有一具发动机故障的情况下，会 比双发动机的波音777更为优越。配备四台发动机还可使A340飞机不受海洋、山区、沙漠和极地等极端偏远地区 地形的影响，而双发延程飞行（ETOPS）限制却制约着双发飞机远程航线的运营（由于A340并不受ETOPS约束，维 珍航空在宣传其A340机队时，曾用一句口号“4 Engines 4 Long Haul”）。
舱室设计
A340-500/600豪华的头等舱 面向295-380座级远程和超远程飞机市场。配备四台发动机的布局可使航空 公司灵活开辟远程和超远程航线。A340系列通过与A330系列相结合，为客户提供了最高程度的运营灵活性和经济 性。A340拥有更安静的客舱，更大的乘客舒适度，头等舱乘客享受每排4个座位的布局，公务舱的布局可确保每 位乘客的座位不是临窗就是靠过道，而经济舱一般采用每排8个座位的布局，可确保乘客距过道最远不超过一个座 位。另外，货舱延续空中客车公司客机特点，空间较大。该型飞机宽大的底舱提高了货运运营效益。A340-600飞 机的客户还可以选择将卫生间、厨房和机组人员休息设施设在底舱。为主客舱节省额外的乘坐空间。 由于空中 客车公司开发了宽大的底舱，航空公司可以用新的方法来增加座位数，改进飞行中的服务，提供创新的旅行产品。

The CS8414 digital audio interface receiver provides an easy interface to digital audio signal sources in-cluding the majority of digital audio test equip-ment. The evaluation board also allows the user to supply clocks and data through a 10-pin header for system development.The CDB4340/41 schematic has been partitioned into 10 schematics shown in Figures 2 through 11. Each partitioned schematic is represented in the system diagram shown in Figure 1. Notice that the the system diagram also includes the interconnec-tions between the partitioned schematics.2.CS4340/41 DIGITAL TO ANALOGCONVERTERA description of the CS4340 is included in the CS4340 data sheet. A description of the CS4341 is included in the CS4341 data sheet.3.CS8414 DIGITAL AUDIO RECEIVER The system receives and decodes the standard S/PDIF data format using a CS8414 Digital Audio Receiver, Figure4. The outputs of the CS8414 in-clude a serial bit clock, serial data, left-right clock (FSYNC), de-emphasis control and a 256Fs mas-ter clock. The operation of the CS8414 and a dis-cussion of the digital audio interface are included in the CS8414 Datasheet.During normal operation, the CS8414 operates in the Channel Status mode where the LED’s display channel status information for the channel selected by the CSLR/FCK jumper. This allows the CS8414 to decode the de-emphasis bit from the digital au-dio interface for control of the CS4340 de-empha-sis filter.When the Error Information Switch is activated, the CS8414 operates in the Error and Frequency in-formation mode. The information displayed by the LED’s can be decoded by consulting the CS8414 data sheet. It is likely that the de-emphasis control for the CS4340 will be erroneous and produce an incorrect audio output if the Error Information Switch is activated and the CS4340 is in the inter-nal serial clock mode.Encoded sample frequency information can be dis-played provided a proper clock is being applied to the FCK pin of the CS8414. When an LED is lit, this indicates a "1" on the corresponding pin locat-ed on the CS8414. When an LED is off, this indi-cates a "0" on the corresponding pin. Neither the L or R option of CSLR/FCK should be selected if the FCK pin is being driven by a clock signal.The evaluation board has been designed such that the input can be either optical or coax (see Figure6). However, both inputs cannot be driven simultaneously.4.CS8414 DATA FORMATThe CS8414 data format can be set with jumpers M0, M1, M2, and M3, as described the CS8414 datasheet. The format selected must be compatible with the data format of the CS4340 or CS4341, shown in the CS4340 and CS4341 datasheets. Please note that the CS8414 does not support all the possible modes of the CS4340 or CS4341, see Ta-ble 1 for details. The default settings for M0-M3 on the evaluation board are given in Tables 3-5.CS4341FormatCS4340FormatCS8414FormatExternalSCLKInternalSCLK 0-2Yes Yes102Yes No210No Yes32Unsupported--4-Unsupported--535Yes No6-6Yes Yes702Yes NoTable 1. CS8414 Supported Formats5.ANALOG OUTPUT FILTERThe evaluation board includes a pair of single pole passive filters. The passive filters, Fig. 3, have a corner frequency of approximately 95kHz with JP3 and JP6 installed and 190kHz without JP3 and JP6.6.INPUT/OUTPUT FOR CLOCKS ANDDATAThe evaluation board has been designed to allow the interface to external systems via the 10-pin header, J9. This header allows the evaluation board to accept externally generated clocks and data. The schematic for the clock/data I/O is shown in Figure11. The 74HC243 transceiver functions as an I/O buffer where jumpers HDR1-HDR6 deter-mine if the transceiver operates as a transmitter or receiver. A transmit function is implemented with the HDR1-HDR6 jumpers in the 8414 position. LRCK, SDATA, and SCLK from the CS8414 will be outputs on J9. The transceiver operates as a re-ceiver with jumpers HDR1-HDR6 in the EXTER-NAL position. MCLK, LRCK, SDATA and SCLK on J9 become inputs.7.POWER SUPPLY CIRCUITRYPower is supplied to the evaluation board by three binding posts (GND, +5V, +3V/+5V) (see Figure10). The +5V input supplies power to the +5 Volt digital circuitry (VA+5, VD+5, VDPC+5), while the +3V/+5V input supplies power to the Voltage Level Converter and the CS4340/41 for evaluation in either +3 or +5 Volt mode. Note, the supply voltages, VCCA and VCCB, to the Voltage Level Converter (LVXC4245) must remain within 2.25 Volts of each other in order to maintain proper operation.8.GROUNDING AND POWER SUPPLYDECOUPLINGThe CS4340/41 requires careful attention to power supply and grounding arrangements to optimize performance. Figure 10 details the power distribu-tion used on this board. The CDB4340/41 ground plane is split to control the digital return currents in order to minimize digital interference. The decou-pling capacitors are located as close to the CS4340/41 as possible. Extensive use of ground plane fill on both the analog and digital sections of the evaluation board yields large reductions in radi-ated noise.9.CDB4341 CONTROL PORTSOFTWAREThe CDB4341 is shipped with Windows based software for interfacing with the CS4341 control port via the DB25 connector, P1. The software can be used to communicate with the CS4341 in either SPI or I2C mode; however, in SPI mode the CS4341 registers are write-only.Run SETUP.EXE from the distribution diskette to install the software. Further documentation for the software is available on the distribution diskette. The documentation is available in the plain text for-mat file, README.TXT.Table 2. System ConnectionsTable 3.

The purpose of this International Standard on Related Services (ISRS) is toestablish standards and provide guidance on the auditor’s 1 professional responsibilities when an engagement to perform agreed-upon procedures regarding financial information is undertaken and on the form and content of the report that the auditor issues in connection with such an engagement.2. This ISRS is directed toward engagements regarding financial information. However, it may provide useful guidance for engagements regarding non-financial information, provided the auditor has adequate knowledge of the subject matter in question and reasonable criteria exist on which to base findings. This ISRS is to be read in conjunction with ISA 120, “Framework of International Standards on Auditing.” Guidance in other ISAs may be useful to the auditor in applying this ISRS.3. An engagement to perform agreed-upon procedures may involve the auditor in performing certain procedures concerning individual items of financial data (for example, accounts payable, accounts receivable, purchases from related parties and sales and profits of a segment of an entity), a financial statement (for example, a balance sheet) or even a complete set of financial statements. Objective of an Agreed-upon Procedures Engagement4. The objective of an agreed-upon procedures engagement is for the auditorto carry out procedures of an audit nature to which the auditor and the entity and any appropriate third parties have agreed and to report on factual findings.5. As the auditor simply provides a report of the factual findings of agreed-upon procedures, no assurance is expressed. Instead, users of the report assess for themselves the procedures and findings reported by the auditor and draw their own conclusions from the auditor’s work.6.The report is restricted to those parties that have agreed to the procedures to be performed since others, unaware of the reasons for the procedures, may misinterpret the results. General Principles of an Agreed-upon Procedures Engagement7. The auditor should comply with the Code of Ethics for ProfessionalAccountants issued by the International Federation of Accountants.1 As explained in ISA 120, “Framework of International Standards on Auditing,” “... the term auditor is used throughout the ISAs when describing both auditing and related services which may be performed. Such reference is not intended to imply that a person performing related services need be the auditor of the entity’s financial statements.”ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURESREGARDING FINANCIAL INFORMATIONEthical principles governing the auditor’s professional responsibilities for thistype of engagement are:(a)Integrity;(b)Objectivity;(c)Professional competence and due care;(d)Confidentiality;(e)Professional behavior; and(f)Technical standards.Independence is not a requirement for agreed-upon procedures engagements;however, the terms or objectives of an engagement or national standards mayrequire the auditor to comply with the independence requirements of IFAC’sCode of Ethics for Professional Accountants. Where the auditor is notindependent, a statement to that effect would be made in the report of factualfindings.8.The auditor should conduct an agreed-upon procedures engagement inaccordance with this ISRS and the terms of the engagement. Defining the Terms of the Engagement9.The auditor should ensure with representatives of the entity and,ordinarily, other specified parties who will receive copies of the report offactual findings, that there is a clear understanding regarding the agreedprocedures and the conditions of the engagement. Matters to be agreedinclude the following:•Nature of the engagement including the fact that the procedures performed will not constitute an audit or a review and that accordingly no assurancewill be expressed.•Stated purpose for the engagement.•Identification of the financial information to which the agreed-upon procedures will be applied.•Nature, timing and extent of the specific procedures to be applied.•Anticipated form of the report of factual findings.•Limitations on distribution of the report of factual findings. When such limitation would be in conflict with the legal requirements, if any, theauditor would not accept the engagement.10.In certain circumstances, for example, when the procedures have been agreedto between the regulator, industry representatives and representatives of theaccounting profession, the auditor may not be able to discuss the procedures ISRS 4400 938ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURESREGARDING FINANCIAL INFORMATIONISRS 4400 939with all the parties who will receive the report. In such cases, the auditor may consider, for example, discussing the procedures to be applied with appropriate representatives of the parties involved, reviewing relevant correspondence from such parties or sending them a draft of the type of report that will be issued.11. It is in the interests of both the client and the auditor that the auditor send anengagement letter documenting the key terms of the appointment. An engagement letter confirms the auditor’s acceptance of the appointment and helps avoid misunderstanding regarding such matters as the objectives and scope of the engagement, the extent of the auditor’s responsibilities and the form of reports to be issued.12.Matters that would be included in the engagement letter include the following: •A listing of the procedures to be performed as agreed upon between the parties. • A statement that the distribution of the report of factual findings would berestricted to the specified parties who have agreed to the procedures to beperformed. In addition, the auditor may consider attaching to the engagement letter a draft of the type of report of factual findings that will be issued. An example of an engagement letter appears in Appendix 1 to this ISRS.Planning13. The auditor should plan the work so that an effective engagement will beperformed.Documentation14. The auditor should document matters which are important in providingevidence to support the report of factual findings, and evidence that the engagement was carried out in accordance with this ISRS and the terms of the engagement.Procedures and Evidence15.The auditor should carry out the procedures agreed upon and use the evidence obtained as the basis for the report of factual findings. 16. The procedures applied in an engagement to perform agreed-upon proceduresmay include the following:•Inquiry and analysis. •Recomputation, comparison and other clerical accuracy checks. • Observation.ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURESREGARDING FINANCIAL INFORMATION•Inspection.•Obtaining confirmations.Appendix 2 to this ISRS is an example report which contains an illustrative listof procedures which may be used as one part of a typical agreed-uponprocedures engagement.Reporting17.The report on an agreed-upon procedures engagement needs to describe thepurpose and the agreed-upon procedures of the engagement in sufficient detailto enable the reader to understand the nature and the extent of the workperformed.18.The report of factual findings should contain:(a)Title;(b)Addressee (ordinarily the client who engaged the auditor toperform the agreed-upon procedures);(c)Identification of specific financial or non-financial information towhich the agreed-upon procedures have been applied;(d) A statement that the procedures performed were those agreedupon with the recipient;(e) A statement that the engagement was performed in accordancewith the International Standard on Related Services applicable toagreed-upon procedures engagements, or with relevant nationalstandards or practices;(f)When relevant a statement that the auditor is not independent ofthe entity;(g)Identification of the purpose for which the agreed-uponprocedures were performed;(h) A listing of the specific procedures performed;(i) A description of the auditor’s factual findings including sufficientdetails of errors and exceptions found;(j)Statement that the procedures performed do not constitute either an audit or a review and, as such, no assurance is expressed;(k) A statement that had the auditor performed additional procedures, an audit or a review, other matters might have come to light thatwould have been reported;(l) A statement that the report is restricted to those parties that have agreed to the procedures to be performed;ISRS 4400 940ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURESREGARDING FINANCIAL INFORMATIONISRS 4400941(m) A statement (when applicable) that the report relates only to theelements, accounts, items or financial and non-financialinformation specified and that it does not extend to the entity’sfinancial statements taken as a whole;(n) Date of the report;(o) Auditor’s address; and(p) Auditor’s signature.Appendix 2 to this ISRS contains an example of a report of factual findings issued in connection with an engagement to perform agreed-upon procedures regarding financial information. Public Sector Perspective1. The report in a public sector engagement may not be restricted only to those parties that have agreed to the procedures to be performed, but made available also to a wider range of entities or people (for example, a parliamentary investigation about a specific public entity or governmental department).2.It also has to be noted that public sector mandates vary significantly and caution has to be taken to distinguish engagements that are truly “agreed-upon procedures” from engagements that are expected to be audits of financial information, such as performance reports.ENGAGEMENTS TO PERFORM AGREED-UPON PROCEDURES REGARDING FINANCIAL INFORMATIONISRS 4400 942Appendix 1Example of an Engagement Letter for an Agreed-upon Procedures EngagementThe following letter is for use as a guide in conjunction with paragraph 9 of this ISRS and is not intended to be a standard letter. The engagement letter will need to be varied according to individual requirements and circumstances.To the Board of Directors or other appropriate representatives of the client who engaged the auditorThis letter is to confirm our understanding of the terms and objectives of our engagement and the nature and limitations of the services that we will provide. Our engagement will be conducted in accordance with the International Standard on Related Services (or refer to relevant national standards or practices) applicable to agreed-upon procedures engagements and we will indicate so in our report.We have agreed to perform the following procedures and report to you the factual findings resulting from our work:(Describe the nature, timing and extent of the procedures to be performed, including specific reference, where applicable, to the identity of documents and records to be read, individuals to be contacted and parties from whom confirmations will be obtained.)The procedures that we will perform are solely to assist you in (state purpose).
