These light systems are classified according to the intensity or brightness they are capable of producing: they are the High Intensity Runway Lights (HIRL), Medium Intensity Runway Lights (MIRL), and the Low Intensity Runway Lights (LIRL).

Keep the appropriate approach controller or PAR controller informed, in advance if possible, of HIRL changes that affect RVR. MEDIUM INTENSITY RUNWAY LIGHTS (MIRL) Operate MIRL or MIRL which control the associated MALSR in accordance with TBL 3-4-10 , except:

Runway edge lights are used to outline the edges of runways during periods of darkness or reduced visibility. These light systems are classified according to the intensity or brightness they are capable of producing: they are the High Intensity Runway Lights (HIRL), Medium Intensity Runway Lights (MIRL), and the Low Intensity Runway Lights (LIRL).

High Intensity Runway Lights (HIRL)- Step 3. Medium Intensity Runway Lights-Step 2. If the airport manager/operator will not agree to the step settings, the provisions of subparagraph c above, must apply. In addition, notify the appropriate FSDO.

2018年6月20日 · 进近灯光系统（Approach Lighting System，ALS），是辅助航行灯光的一种，使飞机于夜间或是能见度低的情况下降落时，提供跑道入口位置和方向的醒目的目视参考。 进近灯光系统安装在跑道的进近端，是从跑道向外延伸的一系列横排灯、闪光灯 (或者两者组合)。 进近灯光通常在有仪器进近程序的跑道上使用，使得飞行员能够目视分辨跑道环境，帮助飞行员在飞机进近到达预定点的时候对齐跑道。 进近中线灯. 先上一张图。 这张图里就是进近灯光系统的组灯。 …

2024年3月1日 · The brightest lights are High Intensity Runway Lights (HIRL). The next brightest are Medium Intensity Runway Lights (MIRL), followed by Low Intensity Runway Lights (LIRL). The Chart Supplement and instrument approach plates list each runway’s lighting specifications.

Runway edge lighting is used to outline the edges of runways during periods of darkness or restricted visibility conditions. These light systems are classified according to the intensity they are capable of producing: Many HIRL and MIRL systems have variable intensity controls, whereas the LIRLs normally have one intensity setting.

2024年10月7日 · HIRL are most commonly found at large, major international airports which facilitate CAT II and CAT III instrument approach procedures. In the United States, it is an FAA requirement for a runway to be equipped with HIRL for CAT II and CAT III operations.

2023年9月21日 · High Intensity Runway lighting (HIRL) is a crucial component of aviation infrastructure that ensures safe and efficient operations at airports, especially during low visibility conditions. HIRL is a lighting system installed along the length of the runway, providing pilots with visual cues and aiding them in determining the runway’s alignment ...

2018年6月11日 · 跑道警戒灯不安装在滑行道上，其光束是单向的，并对准方向使滑向等待位置的飞机驾驶员能看得见，用于警告在滑行道上操纵飞机驾驶员和驾驶车辆的司机，他们将要进入一条现用跑道。 部分灯光系统英文缩写含义. CAT-I PALS：一类精密进近灯光系统. HIAL：高强度进近灯光系统. VASIS：目视进近坡度指示系统. SALS：简单进近灯光系统. PAPI：精密进近航道指示器. LIZ：航向灯. HIRL：高强度跑道灯（边灯） MIRL：中强度跑道灯（边灯） LIRL：低强度跑道 …
