Jeppesen 항공 용어 사전 Definitions (25)

• ILS Categories (ICAO) :

a. ILS Category Ⅰ : DH가 200ft 이상, 시정이 2,400ft 이상, RVR이 1,800ft 이상일 때 approach를 허용하는 ILS approach procedure. 

 

b. ILS Category Ⅱ (특별 승인 필요) : DH가 100ft 이상 200ft 미만이며, Category A, B, C (auto landing이 있는 D)의 경우 RVR이 1,000ft 이상일 때, auto landing이 없는 Category D 항공기의 경우 RVR 1,200ft 이상일 때 approach를 허용하는 ILS approach procedure. 

 

c. ILS Category Ⅲ (특별 승인 필요) : 

     1. ⅢA -  DH가 100ft보다 낮거나 없으며, RVR이 574ft 이상일 때 approach가 허용되는 ILS approach procedure. 

 

     2. ⅢB - DH가 50ft보다 낮거나 없으며, RVR이 150ft 이상 574ft 미만일 때 approach가 허용되는 ILS approach procedure.

 

     3. ⅢC -  DH 및 RVR 제한 없이 approach를 허용하는 ILS approach procedure.

 

d. 어떤 지역에서는 ILS Category Ⅰ approach에 대해 특별 인가가 요구됨. 이러한 지역에서 ILS라 불리는 approach의 추가 범주(additional category)는 특별한 인가 없이 사용할 수 있음. 이러한 ILS approach는 DH 200ft 및 RVR 2,600ft 값보다 높은 minimum을 가짐. 이러한 위치에서 Jeppesen approach chart는 chart heading(차트 제목) 또는 minimum box title에 표기되어 있음.

 

• ILS Cateogories (USA) : 

a. ILS Category Ⅰ : 200ft 이상의 HAT와 RVR 1,800ft 이상일 때 approach를 허용하는 ILS approach procedure.

 

b. ILS Category Ⅱ : 100ft 이상의 HAT와 RVR 1,200ft 이상일 때 approach를 허용하는 ILS approach procedure.

 

c. ILS Category Ⅲ :

     1. ⅢA - DH minimum이 없고 RVR이 700ft 이상일 때 approach를 허용하는 ILS approach procedure.

 

     2. ⅢB -  DH minimum이 없고 RVR이 150ft 이상일 때 approach를 허용하는 ILS approach procedure.

 

     3. ⅢC -  DH minimum이 없고 RVR minimum이 없을 때 approach를 허용하는 ILS approach procedure.

• ILS Categories (ICAO) : 

a. ILS Category Ⅰ : An ILS approach procedure which provides for an approach to a decision height not lower than 60m (200ft) and a visibility not less than 800m (2,400ft) or a runway visual range not less than 550m (1,800ft).

 

b. ILS Category Ⅱ (Special authorization required) : An ILS approach procedure which provides for an approach to a decision height lower than 60m (200ft) but not lower than 30m (100ft) and a runway visual range not less than 300m (1,000ft) for aircraft categories A, B, C (D with auto landing), and not less than 350m (1,200ft) for aircraft category D without auto landing.

 

c. ILS Category Ⅲ (Special authorization required) : 

     1. ⅢA - An ILS approach procedure which provides for approach with either a decision height lower than 30m (100ft) or with no decision height and with a runway visual range of not less than 175m (574ft).

 

     2. ⅢB - An ILS approach procedure which provides for approach with either a decision height lower than 15m (50ft) or with no decision height and with a runway visual range of less than 175m (574ft) but not less than 50m (150ft).

 

     3. ⅢC - An ILS approach procedure which provides for approach with no decision height and no runway visual range limitations. 

 

d. Some areas require special authorization for ILS Category Ⅰ approaches. In these areas, an additional category of approach called ILS is available without special authorization. These ILS approaches have minimums higher than a decision height of 200ft and a runway visual range value of 2,600ft. Jeppesen approach charts, at these locations, will have a notation in the chart heading or in the minimum box titles.

 

• ILS Categories (USA) : 

a. ILS Category Ⅰ : An ILS approach procedure which provides for approach to a height above touchdown of not less than 200ft and with runway visual range of not less than 1,800ft.

 

b. ILS Category Ⅱ : An ILS approach procedure which provides for approach to a height above touchdown of not less than 100ft and with runway visual range of not less than 1,200ft.

 

c. ILS Category Ⅲ : 

     1. ⅢA - An ILS approach procedure which provides for approach without a decision height minimum and with runway visual range of not less than 700ft.

 

     2. ⅢB - An ILS approach procedure which provides for approach without a decision height minimum and with runway visual range of not less than 150ft.

 

     3. ⅢC - An ILS approach procedure which provides for approach without a decision height minimum and without runway visual range minimum.
