Landing Lights/strobes Used During Taxi

Wed Sep 27, 2006 8:24 am

HI everyone,
just wondering if anyone knew why, when an aircraft taxies across an active runway but there are no planes currently using it the flight crew turns on the strobes and the wing lights as well. As soon as they are clear from the runway they then turn off those lights and just use the taxi light until they get to thier assigned runway for takeoff.

I've mainly see this at SFO, however I did experience it when I was in a plane taxiing to the reef runway at HNL. The pilot did turn on the strobes and the wing lights as we crossed the runway to get to the reef.

does anyone have any insight as to why this is done? I can assume its for safety, but if its for safety and its mandatory then why isn't tail logo lights mandatory to be on while taxing to the runway as well. You can turn them off the same time you turn off the wing lights.

What are your thoughts/ideas on this...

I have been taught to turn on strobes and nav lights when corssing any runway, active or not, and at SFO they seem to change their active alot so i could see why this would be useful.

Yep, you just never know when (especially at an uncontrolled airport) there is an aircraft around and that extra light system might just be the difference. It's something that just about every flight school nowadays teaches.

For lack of a better explination, flying is all about being seen. The more of your airplane another pilot can see, the better collision avoidance and situational awareness he has, and the safer you are. You're more likely to see something completely lit up while moving across an active runway (especially from the side) as opposed to just a taxi light, therefore you'd at least make every attempt possible to avoid hitting it. We're told to use strobes while crossing runways when at all possible, unless it creates an unsafe, and unnecessary distration for vehicles or other aircraft around you (ie. here at Daytona we have 2 way taxiways, two airplanes headed in the opposite direction while crossing a runway wouldn't have their strobes on, you'd literally blind the other pilot, and get a false sense of wingtip clearances).

As soon as they are clear from the runway they then turn off those lights and just use the taxi light until they get to thier assigned runway for takeoff.

The FAR's (part 91) require that any ground operations at night be conducted with Nav lights (the red and green ones on the wingtip, plus the white light on the tail) and the anticollision beacon (red rotating and/or pulsating light) on. The taxi light is more for the pilots than anyone else-although I'll admit that it does make you more visible on the ground

Ground operation of strobes and/or landing lights is strongly discouraged, as you could flash blind other pilots, ground personnel, etc. Also (and this was more of a concern before modern "glass" flight decks, when the cockpit lighting was really dim red lights), exposure to intense light sources can screw up the pilots' night vision.

For crossing an active runway, however, IMHO, you can never make yourself too visible-this is a very dangerous environment with a high probability of collision (and many accidents over the years have shown this!). Do you have a safety net if you are accidentally cleared across a runway which another aircraft is using? Mistakes happen...both pilots and controllers!

Most airlines probably have check lists that cover these items. The Part 141 flight school I got my instrument rating at had checklist items covering the operation of all lighting, including the strobes and landing light.

EDIT: It is worth noting that Strobes and Landing Lights are also highly visible durring the day as well as at night.

Hi, it is to make you more visible. I am just a private pilot but I always have my navs on, and I turn on my stobes and landing light when I take the active. Have any of you ever seen planes with flashing landing lights? I see them a lot heading into DAL. Does anyone know what or who this is? I don't think its 737 unless WN has something different on their 737s?

I always thought the plot from there sucked

Yeah WN does have flashing landing lights, 3 I think, but why, I am unsure of

Hey Cessna- thanks a bunch! So it is WN. I wonder why this is! It has always driven me nuts! I think I would be distracted if the landing light on my plane was flashing!

Haha yeah I was somewhere, I think BWI and this was like 0500 and I did not want to be awake and here comes a WN 737 with its huge flashing landing lights totaly blinding me and the other people in the car. VERY annoying.

The answer lies in the previous question about why pilots turn on their landing lights and strobes. Increased visibility. Plain and simple. As opposed to most landing lights out there that are just running all the time, WN's landing lights on their 73's draw more attention...think about it, if someone was flashing a light at you, it would catch your attention, would it not?

Landings are just controlled crashes.

The strobe lights have a better range.Whereas the Logo lights are just Advt.

dont get me started about those airbus pilots who leave those DOUBLE flashing disco lights on while taxying...total loss of night vision  Smile hehe
