Before take-off, the aircraft altimeter subscale shall be set to QNH
of the aerodrome; after take-off, upon reaching the transition
altitude the altimeter subscale shall be set to 1013.2hPa; when an
aircraft is passing through a transition level during descent, the
altimeter subscale shall be set to QNH of the aerodrome.
3.1.2 规定过渡高和过渡高度层的机场
航空器起飞前，应当将机场场面气压的
数值对正航空器上气压高度表的固定指标；
航空器起飞后，上升到过渡高时，应当将航
空器上气压高度表的气压刻度1013.2 百帕对
正固定指标。
当航空器在下降过程中穿越过渡高度层
时，应当将机场场面气压的数值对正航空器
上气压高度表的固定指标。
3.1.2 At aerodromes where transition heights and transition
levels are established
Before take-off, the aircraft altimeter subscale shall be set to the
atmospheric pressure at the aerodrome elevation; after take-off,
upon reaching the transition height the altimeter subscale shall be
set to 1013.2hPa; when an aircraft is passing through a transition
level during descent, the altimeter subscale shall be set to the
atmospheric pressure at the aerodrome elevation.
3.1.3 没有规定过渡高度或过渡高和过渡高
度层的机场
航空器起飞前,应当将机场场面气压的数
值对正航空器上气压高度表的固定指标；航
空器起飞后，上升到600 米高时，应当将航
空器上气压高度表的气压刻度1013.2 百帕对
正固定指标。在机场塔台管制区域内的下降
过程中，航空器应根据空中交通管制员的指
令开始调表。
3.1.3 At aerodromes where transition altitudes or transition
heights and transition levels are not established
Before take-off, the aircraft altimeter subscale shall be set to the
atmospheric pressure at the aerodrome elevation; after take-off
when the aircraft has reached a height of 600m, the altimeter
subscale shall be set to 1013.2hPa. During the process of
descending in the aerodrome tower control area, the aircraft shall
start altimeter setting by the instruction of air traffic controller.

的气压刻度不能调整到机场场面气压的数值
时，应当将气压高度表的气压刻度1013.2 百
帕对正固定指标（此时所指示的高度为零点
高度）。
航空器降落前，如果航空器上气压高度
表的气压刻度不能调整到机场场面气压的数
值时，应当按照降落机场空中交通管制员通
知的假定零点高度（航空器着陆时所指示的
高度）进行着陆。
atmospheric pressure at the aerodrome elevation, it will then be set
to 1013.2hPa before take-off, with the indicated altitude interpreted
as zero altitude.
When the aircraft altimeter subscale cannot be set to the
atmospheric pressure at the aerodrome elevation, landing is to be
made with the assumed zero altitude notified by the air traffic
controller before landing.
3.1.5 为了安全实施高度表拨正，在机场地
区划设了高度表拨正区域。要求低于过渡高
度飞行的航空器，在进出高度表拨正区域的
水平边界时或根据空中交通管制员的指示开
始调整高度表，该水平边界详见ENR 1.7 第4
款。
3.1.5 For the safe execution of altimeter setting, Aerodrome
Altimeter Setting Regions are defined. An aircraft below the
transition altitude is required to start its altimeter setting when
entering or leaving the lateral boundary of Altimeter Setting
Region or by following the instruction of the air traffic controller.
For details of lateral boundaries, please refer to subsection ENR
1.7, item 4.
3.2 航路飞行的垂直间隔，按照飞行高度
层配备。飞行高度层按照以下标准划分：
a. 真航线角在0 度至179 度范围内，高度
由900 米至8 100 米，每隔600 米为一个
高度层；高度在9 000 米以上，每隔
1 200 米为一个高度层。
b. 真航线角在180 度至359 度范围内，高
度由600 米至8 400 米，每隔600 米为一
个高度层；高度在8 400 米以上，每隔
1 200 米为一个高度层。
c. 飞行高度层根据标准大气压条件下假定
海平面计算，真航线角从航线起点和转
弯点量取。
飞行高度层的具体配备标准见飞行高度
层配备示意图（ENR 1.7-7 页）。
3.2 En-route vertical separations are based on flight level
allocation. Flight levels are determined by the following criteria:
a. For a true track between 0o – 179o, a flight level at every
600m from 900m up to 8 100m; a flight level at every
1 200m above 9 000m.
b. For a true track between 180o – 359o, a flight level at every
600m from 600m up to 8 400m; a flight level at every
1 200m above 8 400m.
c. The flight level shall be calculated on the basis of presumed
sea level under standard atmospheric pressure conditions.
