On reaching the cruise flight level, the flight crew should be sure that the FMA displays “ALT CRZ” in its second column, which ensures that the aircraft is at cruise flight level and at Economy Cruise Mach (ECON CRZ MACH).
到达巡航飞行高度层时，飞行机组应确保FMA第2列显示"ALT CRZ"，这就保证飞机在巡航高度层和在经济巡航马赫数(ECON CRZ MACH)。
In cruise, the task sharing is left to the flight crew's appreciation.
在巡航中，任务分配留给机组人员来完成。

FLIGHT PROGRESS | CHECK | PF-PM |
Note: VLS, shown on the PFD, ensures a 0.3 g buffet margin. Therefore, no additional margin is necessary in cruise.
Monitor flight progress in the conventional way.
When overflying a (MANUALLY ENTERED) waypoint:
- Check track and distance to the next waypoint.
- Check the wind and update it if the current wind is significantly different.
When overflying the waypoint, or at least every 30 min check FUEL:
‐ Check FOB (ECAM) and fuel prediction (FMGC), and compare with the computerized flight plan or use the performance application of the EFB.
‐ Check that the sum of the fuel on board and the fuel used is consistent with the fuel on board at departure:
- If the sum is unusually smaller than the fuel on board at departure, or if it decreases, suspect fuel leak. For more information about fuel leak, Refer to FCTM/PR-AEP-FUEL Fuel Leak.
- If the sum is unusually greater than the fuel on board at departure, suspect a fuel quantity overread. For more information about fuel overread. FCTM/PR-AEP-FUEL Fuel Overread
CAUTION: This check must also be performed each time a FUEL IMBALANCE procedure is necessary. Perform the check before applying the FUEL IMBALANCE procedure. If a fuel leak is confirmed, apply the FUEL LEAK procedure.
注意： 每次需要执行燃油不平衡程序时也必须实施该检查。在执行燃油不平衡程序之前完成此检查。如果确认燃油泄漏，执行燃油泄漏程序。

NAVIGATION ACCURACY | MONITOR | PF-PM |
Check on FMS PROGRESS page that the required navigation accuracy is appropriate according to the flown airspace. PRO SPO 51 PBN.
On aircraft equipped with GPS primary, no navigation accuracy check is required, as long as GPS PRIMARY is available.
在装有GPS主用的飞机上，只要GPS主用可用，就无需进行导航精度检查。
Otherwise, a navigation accuracy check must be performed especially when any of the following occurs:
否则必须执行导航精度检查，尤其在出现以下任何情况时：
‐ GPS PRIMARY LOST appears on the ND (GPS)
‐ IRS only navigation
‐ The PROG page displays LOW accuracy
‐ “NAV ACCUR DOWNGRAD” appears on the MCDU.
Refer to DSC-22_20-20-20 Estimated Position Uncertainty.
Methods for checking accuracy:
- If the check is positive (error ≤ 3 N.m): FM position is reliable. 如果检查结果好（误差 ≤ 3 N.m）: FM位置可靠。 Use ND (ARC or NAV) and managed lateral guidance. 使用ND（ARC或NAV）和管理的横向引导。
- If the check is negative (error > 3 N.m): FM position is not reliable. Use raw data for navigation and monitor it.
If there is a significant mismatch between the display and the real position:
如果显示和真实位置之间有明显差异：
Disengage MANAGED NAV mode and use raw data navigation (possibly switching to ROSE VOR, so as not to be misled by FM data).
断开管理的NAV方式，并使用原始数据导航（可能转换到ROSE VOR，以免被FM数据误导）。

FLIGHT RECORD 巡航记录内容
TIME AND FUEL
The flight crew must record the ETA, ATA and fuel remaining on the computerized flight plan or flight log (if there is no computerized flight plan).
飞行机组在飞行中必须在计算机飞行计划或航行记录表（如无计算机飞行计划）上记录飞行时间（ETA、ATA）和剩余燃油数据。
After reaching the Top of Climb, record the cruise time and remaining fuel.
在飞机爬升到爬升顶点（Top of Climb）后，应记下巡航时间和剩余燃油量。
After passing a flight planned waypoint (normally 30 minutes apart), record the fuel remaining
and ETA, ATA.
Record and compare actual fuel status with planned fuel consumption at each waypoint and
monitor any discrepancy or abnormality.
要将实际燃油量与预先计划的燃油量的短少的差异值在每个经过航路点进行记录，以便及时监控到任何燃油消耗的异常现象。
‐ In the event of non-normal fuel consumption or decrease due to fuel leak or any other cause,
make a decision ASAP to divert to alternate airport.
‐ 如因燃油泄漏和其他原因造成的燃油不正常消耗或减少，应及早做出决断，改航备降。
‐ If fuel temperature is close to the fuel freezing point limitation due to flying in low-temperature
area, take actions such as changing altitude, route or acceleration, etc.
‐ 如因低温区域飞行，燃油温度接近燃油冰点温度限制数据，应采取改变高度、改变航路或增加速度等措施。
WAYPOINT OVERFLIGHT RECORD AND FLIGHT CREW PROCEDURE 航路点飞越记录及机组程序
The flight crew may draw a short diagonal line / behind the TO waypoint; and another short diagonal line \ on the over flown waypoint to form a symbol ×, to indicate that that waypoint has been overflown. If an electronic flight plan is used,the time, altitude, fuel quantity and frequency should be recorded, and the changes of DIR TO, offset, and label should be reported when flying over a waypoint.
在飞行时，未飞的航路点的后画一斜线（/），表示预飞的下一个航路点；在飞越的航路点上再画一斜线（\），两个斜线相交叉（×），表示已飞越该航路点；如使用电子飞行计划，应在飞越一个航路点时，记录时间、高度、油量、频率及报告、直飞及偏置、标注等信息变化。
When overflying a waypoint ,the flight crew should check whether the actual track is consistent
with the planned track in order to detect navigational discrepancy in time,
飞越一个航路点时，飞行机组应检查飞机的实际航迹应与预计航路的一致性，以便及时发现导航误差。
Follow specific procedure to report position to ATC when flying out of radar coverage area.
在非雷达管制区域应按规定程序向ATC 进行位置报告。
The FMGS engages the “soft altitude” (SOFT ALT) mode 2 min after the cruise flight level is captured and Mach stabilized. (SOFT ALT) mode allows the aircraft to deviate ± 50 ft from the target altitude to minimize the thrust variation and reduce the fuel consumption.
If the FMA does not display ALT CRZ at the assigned flight level, soft altitude mode will not engage and the predictions will be computed at the preplanned flight level. This will occur when the ATC assigned flight level is lower than the preplanned flight level entered on the PROG page.
If the FMA does not display ALT CRZ at the assigned FL (as may occur when the ATC-assigned FL is lower than the preplanned FL selected initially):
PRESS the [PROG].
ENTER the current cruise flight level.
Note: If the current cruise flight level is above the preplanned FL, selecting the FCU updates it automatically.

CRUISE (CR)
During cruise, the controller maintains cabin altitude at the level-off value, or at the landing field elevation, whichever is higher, but the cabin altitude target is limited to a maximum of approximately 8 000 ft.
在巡航过程中，控制器将座舱高度保持在改平时的高度或着陆机场标高，以较高者为准，但是座舱高度目标最大限制在8 000 ft左右。
If the descent or the approach phase is inadvertently activated (manual approach phase activation, for example), the flight crew may reselect a CRZ FL on the PROG page to reactivate the CRZ phase.
如果不小心启动了下降或进近阶段（如人工生效进近阶段），飞行机组可以在进程页面上重新选择巡航高度层来重新起动巡航阶段。
RECOMMENDED MAXIMUM ALTITUDE (REC MAX)
推荐的最大高度
The recommended maximum altitude is the lowest of the maximum altitude that:
推荐的最大高度是下列最大高度中的最低值：
- ‐ The aircraft can reach with a 0.3 g buffet margin ‐ 抖振裕度为0.3 g时飞机能达到的最大高度
- ‐ The aircraft can fly in level flight at MAX CRZ rating ‐ 能以最大巡航推力额定值平飞的最大高度
- ‐ The aircraft can maintain a V/S of 300 ft/min at MAX CLB thrust ‐ 飞机以最大爬升推力能保持300 ft/min垂直速度的最大高度
- ‐ The aircraft can fly at a speed higher than Green Dot and lower than VMO/MMO ‐ 飞机能以高于绿点并低于VMO/MMO的速度飞行的最大高度
- ‐ The aircraft is certified at. ‐ 飞机被批准的最大高度。
The REC MAX altitude is displayed on the PROG page.
Anti-ice is not taken into account for this computation. Refer to QRH graphs if icing conditions are expected.
该计算不考虑防冰。如果预计有结冰条件，则参考QRH中的图表。
A maximum altitude using a 0.2 g buffet margin is also computed. It is not displayed, but the system uses it to limit CRZ ALT entry.
还要计算使用0.2 g抖振裕度的最大高度。它不显示，但系统用它来限制巡航高度的输入。
CRZ WIND PAGE
The CRUISE WIND page allows the entry and display of predicted wind data (direction and velocity) for each cruise waypoint.
Until weight data is entered and predictions are computed, cruise winds may be entered at any waypoint that is not part of a SID, STAR or approach.
The CRZ WIND page also enables the definition of a temperature at a given altitude to refine the predicted temperature profile.
It is accessed from the CLIMB or DESCENT WIND page, or by pressing the WIND DATA prompt on the VERT REV page of a cruise waypoint. The flight crew can scroll from a cruise waypoint to the next one by using the MCDU scroll keys. Once the last cruise waypoint is reached, the “up arrow”slew key allows access to the first cruise waypoint.
爬升或下降风页面进入，或通过按下在巡航航路点的垂直修正页面上的风数据提示来进入。机组可使用MCDU的滚动键从一个巡航航路点滚动到下一个航路点。一旦最后一个巡航航路点到达后，“向上箭头”滚动键可以使页面进入第一个巡航航路点。
The flight crew can enter wind data for each cruise waypoint at up to four different altitudes.
机组可在每个巡航航路点最多输入4个不同高度的风数据。
Note: This set of four altitudes is defined for the whole cruise phase. Entering a new altitude at
a cruise waypoint will remove the previous altitude from the computations.
这4个高度是针对整个巡航阶段定义的。在巡航航路点输入一个新的高度将从计算中清除前一个高度。
SOFT ALTITUDE MODE (CRUISE)
The soft altitude mode engages when the aircraft reaches the FCU altitude set as the cruise flight level (entered in the F-PLN or on PROG page).
当飞机到达被设置为巡航飞行高度层（在飞行计划或进程页面上输入）的FCU高度时，软高度方式接通。
The soft altitude mode corrects minor deviations from the Mach target by allowing a ±50 ft variation from the CRZ FL. This feature improves fuel efficiency and passenger comfort and minimizes the changes in thrust.
软高度方式允许与巡航飞行高度层有 ±50 ft的误差， 以修正与目标马赫的较小偏差。该特性改善了燃油功效，提高了旅客的舒适度，并将推力变化减至最小。
ENGINE-OUT IN CRUISE PHASE
- ‐ The system sets the managed target speed to the higher of engine-out cruise Mach number or speed, or current speed. ‐ 系统将管理的目标速度设置到单发巡航马赫数/速度，或当前速度中较高的值。
- ‐ “LVR MCT” (or MCT) flashes on the Flight Mode Annunciator. ‐ 飞行方式信号牌上“LVR MCT”（或MCT）闪亮。
- ‐ The PERF CRZ page appears with the “EO CLR*” (clear engine-out) prompt. ‐ PERF CRZ页面出现并有“EO CLR*”（清除发动机失效）提示符。
- ‐ The PROG page displays the engine-out maximum recommended altitude (EO MAX REC ALT). PROCEDURE ‐ PROG页面显示发动机失效后的最大推荐高度（EO MAX REC ALT）。
Perform engine out abnormal procedure.
执行发动机失效非正常程序。
Refer to EFB-IFT-30 One Engine Inoperative Strategies.
请查阅 EFB-IFT-30 一台发动机不工作策略。
Initiate a diversion if necessary.
如果需要，起始改航。
Note: The engine-out descent strategy requires disconnection of the autothrust, and descent in OPEN DES mode.
注： 单发下降策略要求断开自动推力，并以OPEN DES（开放下降）方式下降
Disconnecting the autothrust prevents an automatic setting of THR IDLE; therefore, the autopilot will fly the target speed in OP DES mode, with a thrust manually selected by the crew.
断开自动推力以防止其将推力置于慢车。因此，自动驾驶在OP DES方式时以目标速度飞行，机组人工选择推力。
When reaching the FCU-selected altitude, or whenever normal descent is resumed to a lower altitude, reengage the autothrust.
到达FCU选择的高度时，或任何时候正常的下降恢复到一个较低高度时，重新接通自动推力。
CHECK the MIN DEST FOB value on the FUEL PRED page.
在FUEL PRED页面检查MIN DEST FOB值。
If necessary, update the ALTN fuel value, according to the chosen flight strategy.
若需要，根据选择的飞行策略来升级ALTN燃油值。

SPEED PRESELECTION
If the flight is cleared for a close-in turn or close-in altitude constraint, the flight crew may preselect green dot speed on the PERF CLB page. Once the CLB phase is active, the preselected speed will be displayed in the FCU speed window and on the PFD (blue symbol). Once the turn is completed or the altitude cleared, the pilot will resume the managed speed profile by pressing the SPD selector on the FCU.
如果飞行被允许近距离转弯或近距离高度强制，机组可在PERF CLB页面上预选绿点速度。一旦爬升阶段生效，预选速度将会显示在FCU速度窗内和PFD上（蓝色符号）。一完成转弯或高度强制解除，飞行员可按压FCU上的SPD选择器来恢复管理速度剖面。
Similarly the pilot may select a CRZ MACH number on the PERF CRZ page (constant CRZ Mach segment, for example). When the CRZ phase is active, the preselected CRZ MACH number will be displayed in the FCU speed window and on the PFD. When ECON MACH number may be resumed, the crew presses the FCU SPD selector.
同样，飞行员可在PERF CRZ页面上选择巡航马赫数（如恒定巡航马赫段）。当巡航阶段生效时，预选的巡航马赫数显示在FCU速度窗内和PFD上。机组按压FCU SPD选择器即可恢复经济马赫数。
In either of the above cases, the pilot may cancel the CLB or CRZ preselected SPD/MACH prior to activating the related phase, by selecting ECON on the PERF CLB or CRZ pages.
以上任一种情况，在相关阶段生效之前，飞行员可通过在PERF CLB或CRZ页面上选择ECON（经济），来取消爬升或巡航的预选速度/马赫。
SPD LIM is defaulted to 250 kt below 10 000 ft in the managed speed profile. This may be either cleared or modified on the VERT REV page at the origin (or a climb waypoint).
10 000 ft以下，管理速度剖面的速度限制默认为250 kt。这可在出发机场（或一个爬升航路点）的VERT REV（垂直修正）页面上清除或修改。
