Aircraft Flight Operation Regulations Article 297

No person may operate a civil aircraft in a Category II or III operation unless:1. The flight crew of the aircraft consists of a pilot-in-command (PIC) and a second in command who hold the appropriate authorizations and ratings2. Each flight crew member has adequate knowledge of, and familiarity with, the aircraft and the procedures to be used; and3. The instrument panel in front of the pilot who is controlling the aircraft has appropriate instrumentation for the type of flight control guidance system that is being used.Unless otherwise authorized by CAA, no person may operate a civil aircraft in a Category II or Category III operation unless each ground component required for that operation and the related airborne equipment is installed and operating.Unless otherwise authorized by CAA, no pilot operating an aircraft in a Category II or Category III approach that provides and requires use of a DA/DH may continue the approach below the authorized decision height (DH) unless the following conditions are met:1. The aircraft is in a position from which a descent to a landing on the intended runway can be made at a normal rate of descent using normal manoeuvres, and where that descent rate will allow touchdown to occur within the touchdown zone of the runway of intended landing.2. At least one of the following visual references for the intended runway is distinctly visible and identifiable to the pilot:a) The approach light system, except that the pilot may not descend below 100 feet above the touchdown zone elevation using the approach lights as a reference unless the red terminating bars or the red side row bars are also distinctly visible and identifiable.b) The threshold.c) The threshold markings.d) The threshold lights.e) The touchdown zone or touchdown zone markings.f) The touchdown zone lights.The authorized DH as approved in the preceding paragraph shall refer to the height of the following:1. The DH prescribed by the approach procedures.2. The DH prescribed for the pilot-in-command (PIC).3. The DH for which that aircraft is equipped.Unless otherwise authorized by CAA, each pilot operating an aircraft shall immediately execute an appropriate missed approach whenever, prior to touchdown, the requirements set out in paragraph 2 herein are not met.No person operating an aircraft using a Category III approach without decision height (DH) may land that aircraft except in accordance with the provisions of the operating limitations approved by CAA.

但經民航局核准者,不在此限。
航空器執行第二類或第三類儀降作業時,不得低於核准之決定高度。
但符合下列條件者,不在此限:
一、該航空器能以正常下降率於預定之著陸區落地。
二、駕駛員於進場落地時至少能清晰目視下列一種以上可辨識之參考物:
(一)以進場燈光為參考時,除能目視跑道頭辨識燈或跑道頭燈外,不得下降至著陸區上方一百呎以下。
(二)跑道頭。
(三)跑道頭標誌。
(四)跑道頭燈光。
(五)著陸區或著陸區標誌。
(六)著陸區燈光。
前項核准之決定高度指下列最高之決定高度:
一、進場程序中規定之決定高度。
二、對該機長限定之決定高度。
三、依該航空器配備限定之決定高度。
航空器駕駛員於落地前,如不符合第二項之要求時,應立即執行迷失進場程序。
