5.66 Station Declination (STN DEC)
Definition/Description: For VHF NAVAIDS, the “Station Declination” field contains the angular difference between true north and the zero degree radial of the NAVAID at the time the NAVAID was last site checked. For ILS localizers, the field contains the angular difference between true north and magnetic north at the localizer antenna site at the time the magnetic bearing of the localizer course was established.
Source/Content: Station declinations are derived from official government sources. The field contains one of the alpha characters shown in the following table followed by the value of the declination in degrees and tenths of a degree, with the decimal point suppressed. When the first column of the Station Declination field is coded T or G, the remainder of the field should be coded all zeros.

Column 1 Character	Declination Description
E	Declination is East of Ture North
W	Declination is West of True North
T	Station is oriented to True North in an area in which the local variation is not zero
G	Station is oriented to Grid North

说明:本项的第1列出现G将警告用户，虽然导航台建台磁差值可能不是0，但事实上不清楚网格基准值，妨碍使用定义的数据。

5.67 入口穿越高 Threshold Crossing Height

5.67 Threshold Crossing Height (TCH)
Definition/Description: The “Threshold Crossing Height” specifies the height above the landing threshold on a normal glide path.
Source/Content: The Threshold Crossing Height will be derived from official government sources when available. As provided on Runway Records, the TCH value will be the Glide Slope Height at the landing threshold for runways with ILS or MLS approaches. If an ILS or MLS is not available and an RNAV approach is available it will be the published TCH for that procedure. When ILS/MLS or RNAV values are not available but a published VGSI with TCH is available, it will be used. If none of these values are available, it will be 50 feet. When used on Approach Continuation Records, the field will contain the published TCH for that procedure. When used on ILS or MLS Records, it will be the height of the glide slope at the landing threshold.
COMMENTARY：Based on the information contained in the Source/Content paragraph, it should be noted that the single TCH value provided on the Runway Record may be different than the TCH value provided on the Approach Continuation Record for a procedure to that same runway. These differences may be significant. A comparison of procedure altitude data to threshold elevation and threshold crossing heights should only be made to the Approach Continuation Record. It should also be noted that a TCH associated with the VGSI for the same runway may be different than either value. Some government sources will provide information on these procedure to VGSIdifferences when they are three feet or greater
Used On: Airport and Heliport ILS and MLS Runway, Airport, and Heliport Approach Continuation Records.
Length: 2 characters on Airport and Heliport ILS, MLS and Runway Records 3 characters on Airport and Heliport Approach Continuation Records
Character Type: Numeric
Example: 37, 50, 99 (ILS, MLS and Runway)
044, 055, 102, (Approach)

5.67 入口穿越高(TCH)
定义或描述：说明正常下滑道高于着陆入口的高
数据源或供选编码：如有此项数据，入口穿越高应来自官方资料。跑道记录中，TCH值是下滑道在有ILS或MLS程序的跑道着陆入口处的高。如果ILS或MLS不可用，而有RNAV进近，即公布RNAV程序的TCH。如果以上三者都没有，但公布的VGSI有TCH,则该值可采用。如果上述数据都没有，则为50英尺。当应用于进近续记录，包括该程序的公布TCH。在ILS或MLS记录中使用，其为下滑道在着陆入口的高。
建议：根据上述资料，应注意：跑道记录提供的单独的TCH值，可能与同一跑道的一个程序的续记录的TCH值不同，而且可能有大的区别。只能对进近续记录的程序高度数据与入口标高和入口穿越高进行比较。还要注意：同一跑道的VGSI的TCH可能与这些数据都不同。在这些程序与VGSI的差异大于3英尺以上时，有些官方会提供资料。
应用范围：机场ILS和MLS、跑道记录、机场进近续记录
字节数：
2位应用于机场的ILS MLS和跑道记录
3位应用于机场进近续记录
字符类型：数字
举例：
37、50、99(ILS MLS 和跑道)

5.70 垂直角度 Vertical Angle

5.70 Vertical Angle (VERT ANGLE)
Definition/Description: The “Vertical Angle” field defines the vertical navigation path prescribed for the procedure. The vertical angle should cause the aircraft to fly at the last coded altitude and then descend on the angle, projected back from the fix and altitude code for that fix at which the angle is coded. Vertical Angle information is provided only for descending vertical navigation. The angle is preceded by a “–” (minus sign) to indicate the descending flight.
Source/Content: Values from official government sources will be used when available. In coding of procedures with navaids providing an electronic glide slope, the Vertical Angle is the angle assigned to that glide slope. In coding of procedures with a published VNAV Angle, it is that angle or one calculated by the data supplier. In coding of procedures with no government source vertical angle data, it is always a data supplier calculated value; see Attachment Five, Procedure Coding Rules. The angles are expressed in degrees, tenths and hundredths of a degree, with the decimal point suppressed. The Localizer Only Vertical Angle is a value provided for non-precision use of an ILS procedure as a Localizer Only (Glide Slope Out) procedure.
Used On: Airport and Heliport STAR/Approach Records
Length: 4 characters
Character Type: Alpha/numeric
Examples: -300, -375, -542, -969 (max angle is 9.99 degrees)

数据源或供选编码：如使用，下滑角值要来自官方资料。对有电子下滑道的程序编码时，垂直角度即为指配给下滑道的角度。对公布有VNAV角度的程序编码时，即为该角度或者数据商计算的角度。官方没有公布下降角度数据的程序编码，由数据商计算出该值，见附录5程序编码规则。角度以度、十分位和百分位度填入本项，小数点省略。只有航向台的垂直角度，采用只有航向台(下滑台不工作)的ILS程序当作非精密进近使用的角度。
应用范围：机场SID STAR APCH
字节数：4位
字符类型：字母/数字
举例：-300、-375、 -542、 -969 (最大9.99度)
