这个我先来说几点吧。
轮挡全部挡在机轮前面。开小车可以贴住。开大车轮挡要离开机轮一段距离。因为开大车后飞机会向前动一点。为了不要让机轮受太大压力。起落架安全销要插好。前轮转弯销要拔去。根据不同的机型拔相应的跳开关。这在手册上都能查到到底要拔哪几个跳开关。开车前要做火警测试。别的打泵刹车，打开燃油泵应该都知道吧。

4. Procedure

Subtask 71-00-00-710-131-A
A. Do the Normal Engine Automatic Start Procedure as follows:

(1) General

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:
- AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:
- ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.
CAUTION: REVERSE WINDMILLING CAN OCCUR IF THE AIRCRAFT IS OPEN TO A STRONG TAIL WIND. CAREFULLY MONITOR THE START TO PREVENT A HOT START. REFER TO WIND DIRECTION AND VELOCITY OPERATIONAL LIMITATIONS DIAGRAM.
(a) Do each step of the procedure in sequence. If you abort the start, you must do each step of the sequence again.

(Ref. Fig. 218/TASK 71-00-00-991-232 SHEET 1)
(b) During the start, keep the service air bleed inputs and accessory load to a minimum.

(Ref. Fig. 209/TASK 71-00-00-991-168 SHEET 1)
1 If a tail wind prevents an easy start, position the aircraft toward the wind. (Ref. AMM TASK 71-00-00-860-012)

(2) Do the engine start

ACTION RESULT
1. On the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START.
On the lower ECAM display unit :
- The ENGINE page comes into view. Make sure that :
- The air pressure is between 20 psi (1.4 bar) and 39 psi (2.7 bar).
- The oil quantity is correct.

A. Fill the oil tank by the procedure that follows to avoid overfilling the system
(1) If the engine was shut down for more than 10 hours, motor the engine with the starter for a minimum of two minutes. Check the oil level after the rotor stops. Fill the oil tank as necessary 12-13-79-610-011.
(2) If the engine was shut down for less than 10 hours, check the oil level. Fill the oil tank as necessary 12-13-79-610-011.
(3) Before the first start after an overhaul, or if you drained the fuel or the oil compartments to repair the engine, prime the oil and fuel systems 71-00-00-860-013.
B. Before engine start refer to procedure for a bowed rotor start prevention 71-00-00-700-016.
CAUTION: THE HPC AND HPT ROTORS WILL HAVE IMPORTANT DAMAGE IF YOU DO NOT OBEY THE INSTRUCTION GIVEN IN THE TASK SPECIFIED BELOW.

2. On the ENG panel 115VU:
- Set the ENG/MASTER 1(2) control switch to ON.
On the lower ECAM display unit, on the ENGINE page:
- The symbol for the starter valve is in the open position.
- An automatic dry crank sequence of 30 seconds is perＦＯＲＭed.

3. On the upper ECAM display unit:
- Monitor the management parameters, EPR, N1, N2, EGT, FF.
30 seconds after MASTER switch ON, the A or B indication comes into view below IGN.
4. Monitor the engine start:
CAUTION: IF FUEL COMES ON AND NEITHER IGN A OR IGN B IS DISPLAYED OR NO EGT RISE WITHIN 20 SECONDS AFTER FUEL ON, INTERRUPT AUTOMATIC ENGINE START BY SELECTING ENG MASTER SWITCH TO OFF AND PROCEED WITH A MANUAL ENGINE START WITH 50 SECONDS DRY CRANK PROCEDURE.

5. On the lower ECAM display unit:
- Monitor the oil pressure.
At 43 percent N2 the symbol for the starter valve is in the closed position.
The A or B indication goes out of view.

NOTE: During pack valves closing, the FAULT legends of the AIR COND/PACK pushbutton switches come on until the pack valves are fully closed.

(3) Monitor the engine start:

CAUTION: IF YOU FAIL TO DO THE STEPS THAT FOLLOW, A HUNG START CAN BE THE RESULT.
(a) Monitor the N2 and the EGT carefully during the start for any unusual indications. Sluggish N2 acceleration is an indication of a possible hot or hung start. If this indication is accompanied by a fast increase in EGT when N2 is more than 50 percent, abort the start immediately. The EEC automatically aborts the start if there are unusual indications and N2 is less than 50 percent. The EEC also gives fault indication.
(b) If the EGT is more than the start temperature limit, shut the engine down immediately. Write down the length of the time and the highest temperature during overtemperature.

(Ref. Fig. 210/TASK 71-00-00-991-161 SHEET 1)(Ref. Fig. 210/TASK 71-00-00-991-161 SHEET 2)(Ref. Fig. 210/TASK 71-00-00-991-161 SHEET 3)
(c) Abort the start if the oil pressure does not increase.
(d) Abort the start if the fuel or ignition is accidently stopped.
(e) Monitor all the engine parameters to make a check of the automatic start procedure.
(f) Ignition automatically starts 30 seconds after the engine MASTER Switch on. The starter and the ignition automatically turn off at 43 percent N2.
(g) During the start sequence, if the igniter plug is defective, an automatic ground start abort occurs. The defective igniter plug is indicated by the ECAM system. During the subsequent start attempt the EEC selects the other igniter plug. If this is also defective, the ground start abort sequence again occurs and an ECAM message comes into view.
(h) Make sure that the APU rpm goes back to normal.

NOTE: Automatic dry cranking follows an aborted start.

(j) When the engine idle speed is stable , on the ENG panel 115VU:

1 Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.

NOTE: When the engine start sequence has ended and the engine is at or above idle (with TLA<8 ): on the upper ECAM DU, "AVAIL" is displayed in green (10 seconds) in the middle of the EPR dial in order to indicate that the engine start is successful.

(4) Engine warm-up

(a) No minimum warm-up time is necessary after a usual engine shutdown if the engine is started again in less than two hours.
(b) If the engine was not operated for more than two hours, operate the engine at MIN IDLE for five minutes. This keeps thermal stresses to a minimum. The engine must be warmed-up until the oil temperature is a minimum of -10 deg.C (+14 deg.F) before you move the thrust lever forward.
5. Close-up

Subtask 71-00-00-869-157

4. Procedure

Subtask 71-00-00-710-075
A. Do this test:

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:
- AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:
- ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.
CAUTION: DO NOT OPERATE THE ENGINE IF THE FUEL INLET PRESSURE IS NOT POSITIVE (THE FUEL IS NECESSARY TO LUBRICATE THE ENGINE FUEL PUMP AND THE HMU AND THUS PREVENT DAMAGE).
CAUTION: MONITOR THE START CYCLE VERY CAREFULLY WHEN THE STARTER AIR INLET PRESSURE IS LOWER THAN RECOMMENDED (SPECIAL OPERATION CONDITIONS). THIS CAN CAUSE LONGER TIMES TO GO TO IDLE AND HIGHER EGT PEAKS.

ACTION RESULT
1. On the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START.
On the lower ECAM display unit:
- The ENGINE page comes into view.
Make sure that:
- The air pressure is between 25 psi (1.7 bar) and 55 psi (3.8 bar).
- The oil quantity is correct.
If necessary, fill the oil tank 12-13-79-610-002or 12-13-79-610-002.

NOTE: The oil level in the oil tank can go down by 1.6 USgal (6 l) during start.

2. On the ENG panel 115VU:
- Set the ENG/MASTER 1(2) control switch to ON.
On the upper ECAM display unit:
- Monitor the important parameters N1, N2, EGT, FF.
On the lower ECAM display unit:
- Monitor the oil pressure.
On the lower ECAM display unit, on the ENGINE page:
- The symbol for the starter valve opens.
- At approximately 16 percents N2, the A or B indication comes into view below IGN.
- At 50 percent N2:
The symbol for the starter valve is in the closed position.
The A or B indication goes out of view.

NOTE: When the pack valves start to close the FAULT legend of the AIR/COND PACK1/2 pushbutton switches on the AIR COND panel 30VU come on until the pack valves are fully closed.
NOTE: The engine operates at a stabilized ground idle only when there is a positive oil pressure indication.
High oil pressure peaks can occur in cold weather because of high oil viscosity. The pressure decreases as the temperature of the oil increases.
Ignition automatically starts at 16 percent N2 and the fuel automatically starts at 22 percent N2. The starter and the ignition automatically stop at approximately 50 percent N2.
Engine light-off usually occurs at approximately 10 seconds after you beginning of the start attempt (starter shutoff valve open) and within 2-3 seconds after the FADEC selects the fuel on.
If the engine light-off does not occur within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the ignition, the fuel flow, and dry motors the engine for 30 seconds.
Twenty-five (25) seconds into the dry motoring time, the FADEC systems energizes the two igniters and at 30 seconds, selects the fuel to on.
If when you tryed to start the engine for the second time there is no light-off within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the two igniters, the fuel flow and the starter. There is a dry motoring of the engine during after which the FADEC system will select a start abort. This will cause a start abort indication to come on on the upper ECAM display unit.
If this occurs, on the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.
- Set the ENG/MASTER 1(2) switch to OFF.
- After the starter is cool, the operator must make a decision: try another auto or manual start or stop and correct the problem.

3. When the engine idle speed is stable, on the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.

NOTE: It is recommended that the engine operates at or near idle for a minimum of 2 minutes before you increase to high power. You must move the throttle control lever slowly, carefully and smoothly when possible.
NOTE: You can use taxi time at or near idle as part of the 2 minute warm-up time.

5. Close-up
Subtask 71-00-00-869-098
A. At the end of the test stop the engine(s) (Ref. AMM TASK 71-00-00-710-028).

(1) On the overhead CTL & IND panel 25VU:

(a) Set the EXT LT/BEACON switch to OFF

(2) Stop the pneumatic supply to the aircraft:

(a) Disconnect the HP ground power unit or stop the APU.

(3) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).

这个我先来说几点吧。
轮挡全部挡在机轮前面。开小车可以贴住。开大车轮挡要离开机轮一段距离。因为开大车后飞机会向前动一点。为了不要让机轮受太大压力。起落架安全销要插好。前轮转弯销要拔去。根据不同的机型拔相应的跳开关。这在手册上都能查到到底要拔哪几个跳开关。开车前要做火警测试。别的打泵刹车，打开燃油泵应该都知道吧。

如果你照他讲的，“轮挡离开一段距离”，你就肯定玩完！

问各位高手一个问题:
在上模拟机时，碰到驾驶舱火警信号时，都是立即关车，提柄灭火，但我有一个疑问，此时在实际情况考不考虑假信号的问题，是否需要观察一下?
手册（CFM56-3C)要求是关车、提灭火手柄、关燃油泵、观察火警是否消失、决定是否灭火，不知道各位是如何操作?

试大车时飞机有可能出现弹跳现象，如果轮挡太近，有可能压到它，出现意料不到的问题。
试车出现火警铃响时，一般先收回油门杆，手放到启动柄上，做好停车准备，另询问地面是外部起火还是尾喷口喷火。按情况判断真假，并按手册分类处理。

试车的程序一般如下：（一般表面工作）737系列
飞机到位，加好油；（如果需要较高功率，俗称：大车，需要超过一定的油量，一般左右主油箱加满即可，有需要可全部加满）
试车前，从飞机左边开始绕飞机一圈检查飞机的外部情况，尤其是发动机前面区域不允许有外物，如有需清除，以免吸入发动机损伤内部结构。其他部件安装好，舱门关闭。
轮挡放在机轮前面一般留有大概十几毫米的缓冲空间，因为防止飞机前倾造成轮胎的过度挤压。轮挡不是主要防止飞机前冲的工具，飞机本身的刹车才是主要正常防止手段。
检查完毕，登机关好舱门，检查好跳开关和其他开关后，上电，刹车，检查火警，联系地面。
启动APU，正常后可按试车手册检查飞机系统，并把各种开关打到相应位置。
如果在机场区域，需要联系塔台，经同意后可开始准备启动。
联系地面确认可以启动，一般先左发后右发，左发启动完毕再启动右发。启动时，需要关掉空调等其他设备的引气防止引气不足和APU的EGT超温。
启动过程注意观察N2，N1，EGT和滑油压力等关键参数，正常启动机在N2到达一定转速会自动脱开，如果超过一定时间不脱开可以人工脱开或者终止启动。（CFM56-3）用APU的引气，打开启动机到GROUND位，等N2达到24。6%可以提启动杆，要求稳而迅速，手保持在启动杆上，注意观察主要参数：EGT等。N2到一定转速（46%左右）后启动机会自动脱开。允许EGT最高时稍微进入黄区。直到启动成功手可离开启动杆。然后可再启动右发。
启动成功后需要等发动机稳定后才进行功率测试，起飞功率测试时需要按照手册要求操作，其起飞功率及部分功率等由当地场温场压查相关表格得到相应正常数据范围，试车各种数据需要在各种相应的范围之内。比如737-300在测试起飞功率（大车）时需要把襟翼放到一定的角度，一方面是飞机和发动机内部设计的要求，其次是安全要求（个人理解）。同时要提醒地面人员注意安全！地面人员要求在安全区域警戒。
部分功率测试时，如果需要安装部分功率销，首先要保持慢车，还需要走安全通道，右侧的可从前面沿飞机中线到机头后贴这机身走到功率销孔位置再向发动机走近插销子，左侧的可离飞机外侧较远处由前向后走到和销子孔相平位置后，再横走接近。插好销子后按原路线返回安全警戒区。同时由右侧的人顺便按下电子舱的空地电门。
部分功率测试完毕后，需要保持发动机在慢车功率下五分钟以上再关车，防止发动机出现卡阻现象。
试车完毕，等完全关车后，需要把轮挡放到外侧轮前后，拔下部分功率销和空地电门，并检查渗漏以及相应时间内检查各种油量指示。盖好包皮以及发动机蒙布。
关断APU，关好舱门，撤离登机梯。带好所有工具离开现场。

4. Procedure

Subtask 71-00-00-710-075
A. Do this test:

WARNING: AFTER AN ABORT OF THE ENGINE STARTING SEQUENCE, A DRY CRANK, TO REMOVE FUEL VAPOURS, WILL OCCUR, ACCOMPANIED BY ECAM MESSAGE:
- AUTO CRANK IN PROGRESS

ON COMPLETION OF THE DRY CRANK, ALWAYS PUT THE "ENG/MASTER" SWITCH BACK TO THE "OFF" POSITION WHEN INSTRUCTED BY ECAM MESSAGE:
- ENG MASTER OFF.

IF YOU ONLY CHANGE THE POSITION OF THE ENGINE MODE SELECTOR SWITCH (FROM "IGN/START" TO "NORM"), THE FADEC SYSTEM WILL NOT COMPLETE THE ABORT. THERE IS THUS A RISK THAT THE ENGINE WILL START. THIS CAN CAUSE INJURIES TO PERSONS.
CAUTION: DO NOT OPERATE THE ENGINE IF THE FUEL INLET PRESSURE IS NOT POSITIVE (THE FUEL IS NECESSARY TO LUBRICATE THE ENGINE FUEL PUMP AND THE HMU AND THUS PREVENT DAMAGE).
CAUTION: MONITOR THE START CYCLE VERY CAREFULLY WHEN THE STARTER AIR INLET PRESSURE IS LOWER THAN RECOMMENDED (SPECIAL OPERATION CONDITIONS). THIS CAN CAUSE LONGER TIMES TO GO TO IDLE AND HIGHER EGT PEAKS.

ACTION RESULT
1. On the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to IGN/START.
On the lower ECAM display unit:
- The ENGINE page comes into view.
Make sure that:
- The air pressure is between 25 psi (1.7 bar) and 55 psi (3.8 bar).
- The oil quantity is correct.
If necessary, fill the oil tank 12-13-79-610-002or 12-13-79-610-002.

NOTE: The oil level in the oil tank can go down by 1.6 USgal (6 l) during start.

2. On the ENG panel 115VU:
- Set the ENG/MASTER 1(2) control switch to ON.
On the upper ECAM display unit:
- Monitor the important parameters N1, N2, EGT, FF.
On the lower ECAM display unit:
- Monitor the oil pressure.
On the lower ECAM display unit, on the ENGINE page:
- The symbol for the starter valve opens.
- At approximately 16 percents N2, the A or B indication comes into view below IGN.
- At 50 percent N2:
The symbol for the starter valve is in the closed position.
The A or B indication goes out of view.

NOTE: When the pack valves start to close the FAULT legend of the AIR/COND PACK1/2 pushbutton switches on the AIR COND panel 30VU come on until the pack valves are fully closed.
NOTE: The engine operates at a stabilized ground idle only when there is a positive oil pressure indication.
High oil pressure peaks can occur in cold weather because of high oil viscosity. The pressure decreases as the temperature of the oil increases.
Ignition automatically starts at 16 percent N2 and the fuel automatically starts at 22 percent N2. The starter and the ignition automatically stop at approximately 50 percent N2.
Engine light-off usually occurs at approximately 10 seconds after you beginning of the start attempt (starter shutoff valve open) and within 2-3 seconds after the FADEC selects the fuel on.
If the engine light-off does not occur within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the ignition, the fuel flow, and dry motors the engine for 30 seconds.
Twenty-five (25) seconds into the dry motoring time, the FADEC systems energizes the two igniters and at 30 seconds, selects the fuel to on.
If when you tryed to start the engine for the second time there is no light-off within 10 seconds (15 seconds for extreme cold conditions), the FADEC system automatically stops the two igniters, the fuel flow and the starter. There is a dry motoring of the engine during after which the FADEC system will select a start abort. This will cause a start abort indication to come on on the upper ECAM display unit.
If this occurs, on the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.
- Set the ENG/MASTER 1(2) switch to OFF.
- After the starter is cool, the operator must make a decision: try another auto or manual start or stop and correct the problem.

3. When the engine idle speed is stable, on the ENG panel 115VU:
- Set the ENG/MODE/CRANK/NORM/IGN/START selector switch to NORM.

NOTE: It is recommended that the engine operates at or near idle for a minimum of 2 minutes before you increase to high power. You must move the throttle control lever slowly, carefully and smoothly when possible.
NOTE: You can use taxi time at or near idle as part of the 2 minute warm-up time.

5. Close-up
Subtask 71-00-00-869-098
A. At the end of the test stop the engine(s) (Ref. AMM TASK 71-00-00-710-028).

(1) On the overhead CTL & IND panel 25VU:

(a) Set the EXT LT/BEACON switch to OFF

(2) Stop the pneumatic supply to the aircraft:

(a) Disconnect the HP ground power unit or stop the APU.

(3) Do the EIS stop procedure (Ref. AMM TASK 31-60-00-860-002).

Subtask 71-00-00-862-060
B. De-energize the aircraft electrical circuits (Ref. AMM TASK 24-41-00-862-002).

各位对这个问题都有自己的看法，其实这个问题要因发动机型号而定，但有点安全注意事项是差不多的。只要你按试车单工作是没错的，拿56-7B的发动机来说吧，如果你要试大车就必须拿掉空速管套，不然会出现故障信息，至于轮档怎么放置，按行业标准是试车档主轮前面，离机轮大约10CM就可以，不能靠得太紧，否则在试大车时飞机很可以压上轮档，机轮离开地面，使得磨擦系数减小，飞机向前冲出，我劝试车人员千万要注意。

顺便说一下，我也没试过车，还没到哪个级别，但这是有维修执照人员应该有安全常识。

试车时候，主要靠刹车来稳定飞机，轮挡只是一个附加保护。轮挡需要拖开一点，是为了试大车时给轮子留出足够的移动空间。因为试大车时，飞机会受一侧偏转的力，前轮会变形，可能还会侧移（不过我没见过）。

其实试车各个机型和发动机都有不同的要求,严格按试车单做就可以,试车时要冷静,仔细观察基本没什么问题的,但我看大家说了很多,基本没什么人说安全的事情,试车轮挡要挡,但前轮不能放轮挡.试车前要注意风向并准备灭火瓶,地面人员也要有一定资格,不要安排级别太低的机械员(否则试车员可能会有麻烦的,起不到协助作用),而且要尽量离飞机远一点,不要在飞机移动的半径内,因为大车万一飞机移动会伤害地面人员的,试车员在大车时一定要手把转弯手柄.LS的刚提到了飞机移动的问题,我见过试车出的两次严重的问题,还好没有人员受伤.一次是进气道底下的黄线被吸进发动机了,放炮了,所以进气道区域一定要选择好位置.还有一次,可能南方的师傅不知道,在北方冬季下雪试车时也要注意,如果不清洁轮子下面的雪的话,当一发加马力的时候,飞机很可能会侧移,我见过一次,移动了有2米,还好机械员在飞机的45度角前3米的位置,着实吓了一下.总之工作安全第一,做事情前多想一步,生命呀!!应该珍惜!!!

试车的时候，发动机向前的力是靠刹车来抵消的，而不是轮档。轮挡是用来放置飞机在没有动力（关键是失去液压）时的自由滑动。
如果试车的时候，当发动机启动后，机身受到发动机产生的推力，会有向前移动的趋势。如果轮挡是紧贴在轮子上的，这时轮子就有可能座在轮挡上，轮胎离开地面。也就是说，刹车这是失去作用了。轮挡产生的阻力是不足以阻止发动机大车时的推力的，这时飞机就可能座在轮挡上向前移动。
轮挡实际上的作用是当刹车失效时减缓飞机的向前速度，给操作人员一点反应时间。
所以，试车手册上说，试车时轮挡要在轮子前一点，而不是想当然的紧贴在轮子上。

我要善意地批评这位兄弟:

没人教你也就罢了,也不能说手册没写放置轮挡的距离呀!!

以BOEING系列为例，各机型的AMM ATA71-00-00/501都有:

1、737-300/400/500 Put the chocks 6 to 12 inches（15 to 30 cm）in front and aft of the nose gear and all the main landing gear tires。

2、737-600/700/800/900 Install the chocks，COM-1502 in front and to the rear of the nose gear and all the main gear tires。

（a）Make sure that the forward wheel chocks are 6-12 inches（152-305mm） in front of the tires。

（b）Make sure that the aft wheel chocks are immediately behind the wheels，but do not touch the tires。
