How do you know the direction of the runway?
General runway identification is based on the compass heading the aircraft is facing as it is landing or taking off.
For example, Runway 17/35 is facing approximately 170° in one direction and 350° in the opposite direction..
What color are omnidirectional taxiway lights?
blueOmnidirectional taxiway lights outline the edges of the taxiway and are blue in color. At many airports, these edge lights may have variable intensity settings that may be adjusted by an air traffic controller when deemed necessary or when requested by the pilot.
How do pilots turn on runway lights?
Many nontower airports have pilot-controlled lighting (PCL), which allows pilots to turn on the runway lights and to select the desired intensity. Within a five-mile radius of the airport, pilots activate PCL by keying the microphone button with the radio tuned to Unicom frequency.
When should you turn on anti collision lights?
Per CFR Part 91.209, position lights are required during night operations – from sunset to sunrise. Anti-collision light systems include the aircraft’s beacon and/or strobe lights. Some aircraft have both a beacon and a strobe light system, and other airplanes just have one or the other.
What indicates a closed runway?
Yellow line and arrowhead surface markings indicate that a portion of the runway has been closed and that the threshold has been moved. Possible causes for the relocation include construction or other airport maintenance. The closed area is not available for takeoffs or landings.
What does L and R mean on runways?
The ”L” and ”R” designate the relative position (left or right) of each runway respectively when approaching/facing its direction. A small number of airports have three parallel runways—the runway in the middle gets a “C” for center. During airport operations, runway number designations are pronounced individually.
What color are airport runway lights?
whiteThe runway edge lights are white, except on instrument runways yellow replaces white on the last 2,000 feet or half the runway length, whichever is less, to form a caution zone for landings.
Why are runway lights blue?
Blue Lights: Taxiway edge lights are always blue. The blue taxi lights are easy to spot from the terminal and are often the first airport lights seen by passengers. Blue taxiway lights are typically illuminated after dark and during bad weather.
What are the lights on a runway called?
An approach lighting system, or ALS, is a lighting system installed on the approach end of an airport runway and consisting of a series of lightbars, strobe lights, or a combination of the two that extends outward from the runway end.
What do 4 white lights in a Vasi indicate?
Three red lights indicate that the aircraft is below and four red lights indicate that the aircraft is well below the nominal flight path. Conversely, three white lights indicate that the aircraft is above and four white lights indicate that the aircraft is well above the flight path.
What color are threshold lights?
greenRunway Threshold Lights are provided in a line along the landing threshold at the touchdown end of a runway and define the beginning of the declared Landing Distances. They are green and can only be seen from the approach.
What do runway light colors mean?
When viewed from the landing threshold, the runway centerline lights are white until the last 3,000 feet of the runway. The white lights begin to alternate with red for the next 2,000 feet, and for the last 1,000 feet of the runway, all centerline lights are red.
What voltage are runway lights?
Member. The runway and taxiway lights at airports are operated on a 6.6amp constant current series circuit with a #8 conductor with 5kv insulation. LED lighting is coming to this industry. We now have the opportunity to use lower current and voltages.
How far apart are runway edge lights?
200 feetRunway Edge Light Spacing and Color Both High Intensity Runway Lights (HIRLs) and Medium Intensity Runway Lights (MIRLs) require a maximum spacing of 200 feet between each runway edge light. For runways with intersecting taxiways or other runways, the maximum gap cannot exceed 400 feet.
What is the color of all runway markings?
whiteMarking Colors. Markings for runways are white. Markings defining the landing area on a heliport are also white except for hospital heliports which use a red “H” on a white cross.
