Aircraft Lights.

Sun Aug 07, 2005 2:10 am

How many different sets of lights do aircraft have and when are they switched on and off,also do airliners and GA aircraft have the same lights.?Is it correct that landing lights are switched on at 10,000 feet?
your pilots today on this 747 flight are captain oliver hardy and assisting will be FO stan laurel.Have a safe flight

Just off the top of my head and without reference to regulations:

  • To fly at night "nav" or "position" lights, red at the left wingtip, green at the right and white astern.


  • Anti-collision light which is normally a red rotating beacon but may simulate the flash of a rotating beacon without any moving parts. On when the engines are going to be operating.


  • Strobe lights more or less colocated with the nav lights. On when taking the runway, off in instrument conditions SCD.


  • Landing lights. On below ten thousand feet is the rule of the day.


  • Separate taxi lights because landing lights are to bright for this and may burn out quickly without enough airflow over them.


  • Possibly runway exit or turnoff lights, angled out about 45 degrees or so to either side of the nose.


  • Ice detection lights in the fuselage or pylon, illuminating the leading edge of the wings.


  • Possible logo light, from wingtips to vertical fin to illuminate company tail. These are great for spotting another plane over a sea of lights like Los Angeles.


  • Seaplanes might have a white 360o anchor light, lit when at anchor. This might have gone away over the years but I recall seeing them on older amphibs.


  • If anyone would like to jump in and sharpshoot me on any of these feel free.

    Slam you got them. A few things that I seem to do different than my peers.

    I use the taxi light when I have the aircraft moving on the ground day, or night.

    I use the logo and Ice FL180 and below, only night.

    And I use the outbord land lights B737 classic only night, or reduced vis daytime.

    GA aircraft may have fewer lights. The Cessnas I fly don't have separate land/taxi lights, and no tail or "logo" lights. The only ice detection light I have is my flashlight. There is an interior panel light, and airliners have those and other cockpit lighting as well.

    I generally operate my landing light as part of the pre-flight check, and then (during the day) as soon as I'm cleared to enter the runway for takeoff, and continue to operate it within the Class D airspace of the controlled airfield (or about 10 minutes at a non-controlled field.) The before takeoff and after takeoff checklists generally include a note about landing lights, and are executed at approximately those phases of flight. At night, of course, it's on before I roll.

    As SlamClick mentioned, the beacon lights are on any time an aircraft's engines are operating. Strobe lights are used at night as soon as I'm cleared to enter the runway for takeoff, and extinguished as I exit the runway after landing. They are switched off in clouds so as not to blind the pilots or damage their accumulated night vision. They are switched off for taxi and parking so as not to blind pilots of other aircraft. This is generally true for airliner operation as well.

    The Nav lights are always red on the pilot's left and green on his right, another similarity to oceangoing vessels.

    # Seaplanes might have a white 360o anchor light, lit when at anchor. This might have gone away over the years but I recall seeing them on older amphibs.

    When a seaplane is anchored, it must display a white anchor light visable through 360 degrees. From the moment it splashes down til the moment it takes off it is a vessel operating under the jurisdiction of the United States Coast Guard if in US Territorial Waters.

    As for GA aircraft, the number of lights may vary even between ships of the same design. Cessna's 340 and 400 series aircraft came with one single lamp retractible landing light on the pilot's side and a single nosewheel taxi light. However, as an add-on a second retractible landing light was available on the co-pilot's side. Also, the RAM modified C414s with the water cooled engines have flush mounted landing lights mounted on the outside position of each engine nacelle in place of one of the air intakes. Our 414 has separate wingtip housings for the anticollision strobes due to the winglets it has.

    As far as operations are concerned, we operate much like the Part 121 carriers. Nav lights come on as soon as the electrical does and landing lights extended and illuminated during the final stage of taxi. These landing lights take approximately five seconds to fully deploy. The taxi light is illuminated for all takeoffs and landings but generally left off during daylight taxi operations. Strobes come on when the landing lights do for takeoff and are switched on during initial descent. During night ops they may be left on enroute unless IMC are encountered.

    As for the landing lights, we usually inspect them for smooth operation in the hangar due to their complex design. Unlike most other aircraft, they extend forward and are completely unusable in the stowed position. Their control switch has three positions-retract, extend and on. To operate them, the pilot selects extend and then returns the switch to the on position (middle position). To extinguish them, you return the switch to the retract position.

    There are also white Recognition Lights, standard fit on Metro IIIs and 23s (where they are mounted with the landing lights just outboard of the wing fences) and optional on many lighties. There are also white lights on the trailing edges of the wingtips on many airline a/c types, are these part of the Nav lights system?

    That doesn't sound right to me. It's over two years since I've worked on a Cessna twin, but IIRC the middle position is light OFF and the top position is extend/light ON, i.e. the lights could be extended and lit but could be switched off without retracting them.

    It's so that other boats can manoeuvre around it. I have never seen an aircraft operate on the water at night and would be very surprised if it was legal to do so.

    Now that I think about it, I believe you're correct. Middel position is off and the top position is on. Here boat registration is a state function, so whether a seaplane or amphib has a boat reg depends on its home port. Some states such as Arizona also require aircraft based in state to register with the state aeronautics department.

    As for the anchor light, that is required by maritime law. Once a seaplane or amphib splashes down, it is subject to maritime law and rules of the road. Vessels at anchor must display a 360o light between the hours of sunset and sunrise and may not anchor within a channel or anywhere that they might obscure or obstruct an Aid to Navigation (buoy, daymark, or navigation beacon).

    Ahh, so that's why some flights have the wings illuminated for the whole duration. But, who checks for ice? Seems like they're too far away and at too awkward an angle for the flight crew. Does the cabin crew do a check before landing? Seems like if they didn't, it'd be too late by the time they really needed those lights.

    Ice inspection lights are something of a throwback to earlier days. Most modern jet a/c have anti-ice, not de-ice, where bleed air is used to heat the leading edges so that ice can't form in the first place. In those a/c the crew don't really need to see the wings. On a/c with rubber de-icing boots, the crew have to monitor the ice build-up and operate the boots at a rate to remove the ice satisfactorily. These a/c tend to be the ones with straight wings that can be seen from the cockpit. There is also alcohol anti-icing, which pumps alcohol through a myriad of tiny holes in the leading edge; one of the Citation models (IIRC the S-II) has this system.

    I was flying in an Air Canada A319, and as we approached Saskatoon at night, I could see the strobes flashing as we descended through the clouds. As soon as we touched down on the runway, the strobes turned off. Is this a feature that can be used? Other A319s/A320s I've flown on, the strobes stay on till we clear the runway.

    This is a feature on AC A320 series aircraft (I had assumed it was standard on Airbuses generally, but maybe not). When the airplane lands, it automatically switches off the strobes and turns on the beacon (through the weight on wheels sensors, but can't remember if it's the mains or the nose).

    Typically airliners will (should) turn on the taxi light before they start moving - this is an indication to the ground crew that the airplane is in motion.

    It's common in Canada to fly with landing lights on during bird migration season, to make the airplane more visible. By the way, if you're about to hit a bird, it's best to climb - birds tend to dive to avoid trouble.

    I recommend using the taxi light for daytime visibility, rather than the landing light.

    A few years ago, I had the landing light on for increased visibility in a congested area. All was well until I smelled something burning, and shortly thereafter discovered smoke rising from underneath the panel. Turned back, hauled ass toward the nearest airport, and rolled the trucks. While running the emergency checklists, I burned my fingertip while turning the landing light off.

    By the time I got stopped on the ground, there was a great deal of smoke pouring out of the panel. Later, it was found that the landing light switch (which supposedly has a built-in circuit-breaker) failed, and melted itself to surrounding wires and connectors.

    Now I only use the lower-powered taxi light for daytime visibility.

    Also, with respect to the strobes, I have noticed the same feature on MD-80's. Even on take-off, the strobes don't begin flashing until what appears to be V1 (just before rotation). They also seem to shut off right after touchdown during landing. Perhaps, I should ask some mad-dog drivers today.

    Not sure if that was sarcastic, Hawk, so I'll ramble on...slap me if I'm being obvious  bomb 

    Even if no intentional wrangling, or unintentional neglect of symptoms, is at work here, CBs are only reliable for so long, and even 99.98% reliable isn't very reassuring given the number of CBs on the number of Cessnas built and flying over the years. I'm not surprised at all that the CB didn't trip, that's how we used to get most of the work at the shop.

    BTW, usually the problem is from slight corrosion on the contacts allowing the CB to heat up repeatedly over a long period of time without tripping- which can eventually fuse the CB contacts together and render it inop in an overload situation. Occasionally, it's a mechanical failure inside the CB that shorts the contacts and lets the CB run on overload.

    I used to use a temp gun on the CB panel during initial runup during diagnosis or after a repair to find problems- and more than once found faulty circuits that hadn't created any problems...yet Who knows how long it had been heating up before it finally got hot enough to smell in the ventilated (I'm assuming) cockpit. What was the weather, 2H4? Did you have your cockpit vent blowing across the pnl, or your face, or turned down? Or was it the visible smoke that first tipped you off? BTW, great response in landing. Hopefully your entire landing light circuit was rewired from at least the CB, and if they uprated the circuit (properly! and only if needed!) you may not have any further adventures of this sort....but I can't blame you for not trusting the LL for visibility use anymore. Besides, if your taxi light is typical, it will draw less juice and save a few cents in gas for the same function...

    On the flip side, I have seen (in GA) more poorly maintained ECBs, and some downright dangerous mods that I shudder to mention. More often than not it's the lighting circuits that get chopped up, b/c some people think they are the simplest to understand or tap in to. (see Fred, that wire goes right to the landing light...) Some people (no implication, 2H4 ) think that the wiring circuits on their little plane are just like the '77 chevelle they wired an electronic tach on to and do some really stupid stuff- and this even refers to A&P mechs, when they can get away with it.*

    (*Strictly speaking GA here, but if any mx techs have similar stories I'd love to hear them! but maybe this is a bit too off topic...)

    A good airmanship is to turn all exterior light when crossing any runway,,, and use taxi lights on daytime when aircraft is moving on ground.

    What was the weather, 2H4?



    I remember it being a hot, muggy summer day.





    Quoting Electech6299 (Reply 27):
    Did you have your cockpit vent blowing across the pnl, or your face, or turned down?



    I think the vent was aimed either at my forehead or my chest. I like to keep it away from the mike so there's less noise when transmitting.





    Quoting Electech6299 (Reply 27):
    Or was it the visible smoke that first tipped you off?



    No, it took awhile before the smoke was visible. The smell is what first tipped me off. I was on a commercial stage check, which involves going up with a senior instructor. At first, upon smelling the smoke, I was half-convinced the old codger was trying to pull something on me to test my judgement....lighting a cigarette lighter, or something. Despite my multiple inquiries, he kept insisting we could continue with the maneuvers...after all...he didn't smell anything.

    I figured, test or no test, the prudent thing to do was abandon the flight and haul ass back to the airport, so I told him so and turned the airplane around. At that point, he finally smelled the smoke, and together, we ran the checklists and got back on the ground.

    By the way...in an evacuation, there's an easy way to tell which pilot is the student, and which pilot is the instructor. The instructor is the one prudently shutting things down and securing the airplane. The student, on the other hand, is the one who, upon coming to a stop, grabs his/her logbook, jumps out, and runs like hell.

    When the airplane lands, it automatically switches off the strobes and turns on the beacon (through the weight on wheels sensors, but can't remember if it's the mains or the nose).

    As far as I know, the beacon light is required to remain on from engine start-up to shut-down.

    Our landing lights are turned on whenever we climb and descend....10,000ft means nothing to us. Also at night when not in the cruise, our logo lights are on.

    In europe it is recommended to switch on the landing lights at 10.000 (FL100) descending. And to switch them off when climbing through FL100.

    However this is not mandatory it is recommended. On the A318-A321 the landinglights are stowed in the underside of the wing inboard of the engines. when selected on the landing lights will extend. However when selecting them on above 250 knots gives a noticable rumbling through the airframe. For this reason it is normal company policy to keep landing light Iretracted till the speed is 250 knots or below.

    When crossing an active runway it is recommended to switch the strobe lights on. I have never switched on all the lights when we crossed a runway. I can not see the advantage of this because your landing lights face forward while the traffic is coming from a 90 degree angle to you. So in daytime they will not see any of the landing lights.

    Trust me when you are in some dodgy airports crossing a runway, you want to be lit up like a Christmas tree and be seen for miles! I personally switch on the wing lights also when crossing the runway in Bombay. May seem like overkill...but better than be-killed!

    Having flown to quite some dodgy airfields but still only use the strobe lights when we are crossing a runway. Cant see any advantage in switching on the landing lights when crossing a runway in daylight. Airdraft on approach will not see your landing lights. However your wing lights is a good idea have to remember that one. And you don't have to go to a dodgy airport to almost get killed there are a few normal airfields where they try this around in spain aswell.
