各种外部灯光的介绍

Wing illumination 机翼照明灯

The wing illumination lights supply light to the leading edge of the wings. At night, this lets the pilots see when ice collects on the on the wing leading edges. 大翼照明灯为大翼前缘提供照明。这样可使飞行员在夜间看到大翼前缘的结冰情况

The wing illumination lights are on the right and left sides of the fuselage above and forward of the wings. 大翼照明灯位于机身左右侧,大翼的上方和前方

The control switch is on the P5 forward overhead panel.控制电门位于P5前头顶板上

With the two-position toggle switch in the ON position, 115v ac will go to the wing illumination light. A fixed step down transformer in the light assembly decreases the voltage to 12 volts. 当两位拨动电门处于ON位时,115v交流电将进入大翼照明灯。灯组件中的固定降压变压器将电压降低至12伏

组成:

  • Lens assembly with lens, reflector and captive screws 带透镜、反光镜和系留螺钉的灯罩组件
  • Halogen lamp 卤素灯泡
  • Lamp retainer wire spring 灯固定弹簧
  • Lamp socket assembly 灯座组件
  • Light housing with transformer 带变压器的灯壳

机翼照明灯

Landing lights 着陆灯

The landing lights help the pilots to see the runway during takeoff and landing. 着陆灯帮助飞行员在起飞和着陆期间看清跑道

The fixed landing lights are in the wing root area of each wing. 固定着陆灯位于每个大翼的翼根区域

The control switches for the fixed landing lights are on the P5 forward overhead panel.固定着陆灯的控制电门位于P5前头顶板上

固定着陆灯 组成:

  • Lens assembly 灯罩组件
  • Lamp 灯泡
  • Step down transformer 降压变压器

固定式着陆灯

The retractable landing lights are on the fuselage, adjacent to the ram air inlet panels. 可收放着陆灯位于机身上,与冲压空气进口板相邻

The control switches for the retractable landing lights are on the P5 forward overhead panel. 可收放着陆灯的控制电门位于P5前头顶板上

可收放着陆灯 组成:

  • Lens assembly 灯罩组件
  • Lamp 灯泡
  • Retainer screws 固定螺钉
  • Extend/retract motor 放下/收上马达

左 可收放着陆灯

Position light 位置灯

The position lights show this information to persons in other airplanes or on the ground: 位置灯向其他飞机上的人或地面人员显示此信息:

  • Airplane position 飞机位置
  • Direction 航向
  • Attitude 姿态

The position lights are red, green, and white incandescent lights. The left forward position light is red. The right forward light is green. The tail position lights are white. 位置灯为红色,绿色和白色的白炽灯。左前位置灯是红色的。右前方位置是绿色的。尾部位置灯是白色的

There are position lights in the tip of each wing. These lights are in the leading and trailing edge of the wing tip. 每个翼尖都有位置灯。这些灯位于翼尖的前缘和后缘

The control switch for the position lights is on the P5 forward overhead panel. 位置灯的控制电门位于P5前头顶板上

With the position lights switch in the STEADY or STROBE & STEADY position, 115v ac goes to the step down transformers. The step down transformers decrease the 115v ac to an operating voltage for the position light. 位置灯电门处于STEADY或STROBE&STEADY位时,115v交流电进入降压变压器。降压变压器将115v交流电降低到位置灯的工作电压

位置灯

Anti-collision lights 防撞灯

The anti-collision lights make the airplane easier to see in the air and on the ground. 防撞灯使飞机在空中和地面时更容易被看到

There are five anti-collision lights on the airplane. Two red anti-collision lights (beacons) and three white anti-collision lights (strobe). Each light assembly has a xenon arc flashtube and solid state circuits to operate the flashtube. 飞机上有五个防撞灯。两个红色防撞灯(信标)和三个白色防撞灯(频闪)。每个灯组件都有一个氙弧闪光管和固态电路来操作闪光管

One red anti-collision light (beacon) is on the top and bottom of the fuselage. The upper and lower anti-collision lights (beacons) are the same. 机身顶部和底部各有一个红色防撞灯(信标)。上下防撞灯(信标)是相同的

There are three white anti-collision lights (strobe), one on each wing tip and one on the tailcone of the airplane. 有三个白色防撞灯(频闪),每个翼尖上有一个,飞机尾锥上有一个

Control switches for the anti-collision lights are on the P5 forward overhead panel. There is a control switch for each anti-collision system. The anti-collision lights flash at a rate of 42 times per minute. The red anti-collision lights flash at the same time. 防撞灯的控制电门位于P5前头顶板上。每个防撞系统都有一个控制电门。防撞灯以每分钟42次的频率闪烁。红色防撞灯同时闪烁

防撞灯

Taxi and runway turnoff lights 滑行和跑道转弯灯

Taxi and runway turnoff lights let the pilots see the taxiway or runway during taxi. 滑行和跑道转弯灯让飞行员在滑行时看到滑行道或跑道

The taxi light is on the front of the nose landing gear strut. It is below the nose wheel steering actuator. 滑行灯位于前起落架支柱的前部。它位于前轮转弯作动筒下方

The runway turnoff lights are on the leading edge wing root, next to the wing-to-body fairing. They are adjacent to the fixed landing lights. 跑道转弯灯位于前缘翼根处,靠近翼身整流罩。与固定着陆灯相邻

Three switches on the P5 panel control the taxi and runway lights. There is one switch for the nose gear taxi light and one switch for each runway turnoff light. P5面板上的三个电门控制滑行和跑道灯。前起落架滑行灯有一个电门,每个跑道转弯灯有一个电门

滑行和跑道转弯灯

Logo lights 航徽灯

The logo lights help show the airline logo or emblem on the vertical stabilizer. 航徽灯帮助显示垂尾上的航徽或徽标

The lights are on the upper surface of each horizontal stabilizer. They are near the leading edge. 灯位于每个水平安定面的上表面。靠近前缘

You use the logo light switch on the P5 forward overhead panel to control the logo lights operation. 使用P5前头顶板上航徽灯电门来控制航徽灯操作

When the logo lights switch is in the ON position, 115v ac goes to the logo light. The logo light has a step-down transformer. The transformer decreases the 115v ac to 12v ac. 当航徽灯电门处于ON位时,115v交流电进入航徽灯。徽标灯有一个降压变压器。变压器将115v伏交流电降低为28伏交流电

航徽灯 组成:

  • Light housing assembly 灯壳体组件
  • Lens 灯罩
  • Lens retainer 灯罩保持器
  • Transformer (not shown) 变压器(未显示)
