滑行道(taxiway),是機場內供飛機滑行的,连接跑道停机坪飞机库航站楼等设施的道路。滑行道通常由表面坚硬的材料铺设成,例如沥青水泥,但有些小型机场可能使用草坪砂砾
繁忙的机场通常会建设高速或快速脱离滑行道,使飞机以较高的速度脱离跑道。这样可使飞机更快离开跑道,让飞机以较小间隔起降。

滑行道指示牌[编辑]

这些标志通常可以被组合使用,此例中为一个方向标志,一个位置标志以及一个跑道标志.

滑行道指示牌,在飛機於滑行道滑行時,指引方向和提供注意資訊。但在一些較小型的機場,滑行道指示牌設置數量較少,甚至沒有設置,而是以機場指示圖來替代。

以下為在機場常見的滑行道指示標誌

操作指引牌[编辑]

一条滑行道的位置标志
指向滑行道B的方向标志
  • Location signs – yellow on black background. Identifies the runway or taxiway currently on or entering.
  • Direction/Runway exit signs – black on yellow. Identifies the intersecting taxiways the aircraft is approaching, with an arrow indicating the direction to turn.
  • Stop Bar signs – white on blue background. The designation consists of the letter S followed by designation of the taxiway on which the Stop Bar is positioned. This sign isn't standard. [1]
  • Other – many airports use conventional traffic signs such as stop and yield signs throughout the airport.

命令性指示牌[编辑]

禁止通行标志

Mandatory instruction signs are white on red. They show entrances to runways or critical areas. Vehicles and aircraft are required to stop at these signs until the control tower gives clearance to proceed.

  • Runway signs – White text on a red background. These signs identify a runway intersection ahead, e.g. runway 12-30 in the photo above.
  • Frequency change signs – Usually a stop sign and an instruction to change to another frequency. These signs are used at airports with different areas of ground control.
  • Holding position signs – A single solid yellow bar across a taxiway indicates a position where ground control may require a stop. If two solid yellow bars and two dashed yellow bars are encountered, this indicates a holding position for a runway intersection ahead; runway holding lines must never be crossed without permission. At some airports, a line of red lights across a taxiway is used during low visibility operations to indicate holding positions. An "interrupted ladder" type marking with an "ILS" sign in white on red indicates a holding position before an ILS critical area.

滑行道灯光[编辑]

滑行道边缘灯

為了滑行道在夜間也可以作業,滑行道在設計上常設有燈光照明設備,但有些小型機場並沒有此設備。

  • 滑行道边缘灯: used to outline the edges of taxiways during periods of darkness or restricted visibility conditions. These fixtures are elevated and emit blue light.
  • 滑行道中线灯: They are steady burning and emit green light located along the taxiway centerline
  • Clearance Bar Lights: Three in-pavement steady-burning yellow lights installed at holding positions on taxiways
  • Runway Guard Lights: Either a pair of elevated flashing yellow lights installed on either side of the taxiway, or a row of in-pavement yellow lights installed across the entire taxiway, at the runway holding position marking at taxiway/runway intersections.
  • Stop Bar Lights: A row of red, unidirectional, steady-burning in-pavement lights installed across the entire taxiway at the runway holding position, and elevated steady-burning red lights on each side used in low visibility conditions (below 1,200 ft RVR). A controlled stop bar is operated in conjunction with the taxiway centerline lead-on lights which extend from the stop bar toward the runway. Following the ATC clearance to proceed, the stop bar is turned off and the lead-on lights are turned on.

Taxiway edge lights are spaced 75 feet apart. These lights can be closer together at taxiway intersections. On straight segments, Taxiway Centerline Lights are spaced at either 50 or 100 foot intervals depending on the minimum authorized visibility. On curved taxiway segments, Taxiway Centerline Lights may be required to be closer together.[2][失效連結]
