Recognition Lights in Cruise

Recommended Posts

What is the SOP on aircraft recognition lights? Are they on during all phases of flight? When I've flown commercial and sat near a wing I don't remember ever seeing wing inspection lights on. So my question is, when are the wing and tail lights turned on and when are they turned off?While we're on the subject, my understanding is that the flashing anti-collision lights must be turned on right before the engines are started. Those lights indicate to ground crew (who may be wearing hearing protection) that the engines are on.Strobe lights are turned on just before take off.And navigation lights (the red and green lights) are on at all times.I know there are real pilots here so please correct me where I'm wrong.thanks.

Nav Lights are not required in the day time, atleast in the US and for Part 91 operations, but I don't know about 135 or 121. I know it's my flight school's policy to only use Nav Lights when they're required, which is sunset to sunrise (FAR 91.209 (a)), as they are generally too dim to be seen in daylight and would mainly just be burning out the bulb quicker. I don't know how this would work with airlines though, Part 121 may have stricter policies.----------------------------------------------------------------John MorganReal World: KGEG, UND Aerospace Spokane Satillite, Private ASEL 141.2 hrs, 314 landings, 46 inst. apprs.Virtual: MSFS 2004"There is a feeling about an airport that no other piece of ground can have.

The policy for the four biz jets my company owns is all on all the time while flying - day or night. Anything to make the aircraft more visible. Though there is definitely a greater cost.

Our use of lights in the airline world is the same, day or night, it makes no difference. We use all our lights day or night. It helps you be seen, but more importantly, it is one less thing a lawyer can attack you with in court.

My company's policy:Position (nav) lights and beacon on before engine start - this indicates to the marshaller and ground crew that engine start is about to happen.Taxi lights for all ground movement.Landing lights, strobes, and recognition lights go on when taking the runway for takeoff and they remain on until clear of the runway after landing.Landing lights can go off passing 2000' AGL at the discretion of the PIC.Recognition lights and strobes can be turned off at the discretion of the PIC if they become distracting in the clouds or in other situations.Exiting the runway, strobes, landing lights, and recognition lights off, taxi lights on.At shutdown, position lights and beacon remain on until prop movement ceases.John

NAV lights on a Warrior are barely noticble even close up in the daylight, but yeah, I'm sure there's a lawyer out there that would reach for it. If they can sue over the attitude indicator failure incident with that non-instrument rated Missourri government official, nav lights should be a snap.

Actually, you probably wouldn't want to turn on the nav lights during the day on a Piper single because that function dims the landing gear status lights on the retractables. Many "dim" pilots have thought they had a landing gear problem because the nav lights were left on during the day.

Yeah, I'm in fixed gear right now finishing instrument, though I hope to be in an Arrow for my complex soon.----------------------------------------------------------------John MorganReal World: KGEG, UND Aerospace Spokane Satillite, Private ASEL 141.2 hrs, 314 landings, 46 inst. apprs.Virtual: MSFS 2004"There is a feeling about an airport that no other piece of ground can have.

hanging out watching airplanes some nights doing their approach, I have noticed sometimes they forget to turn on the landing lights, I have even seen smaller airplanes without strobes. One little cessna forgot to put his beacon on. lolI sure hope these people don't crash into somebody

In JAA land it is mandetory for all aircraft over 5700kg to have their anti-collision and navigation lights on day and night. Recognition lights are the lights used to taxi at night or during low viz or low light. Those should be switched off after take-off. Obviously any white light can be confused for a rear navifation light and, as recognition/taxi lights are quite bright, then the red/green wing navigation lights can be obscured making it difficult for one airraft to determine the other aircraft's orientation at night.

Certainly my experience is that on the light aircraft I have flown, the landing light doesn't add any perspective, just using the run way edge lights in one's peripheral vision produces good and consistent results. However,the landing light should be on, except when specifically being trained to land at night with a simulated electrics failure.

Recognition lights are basically used like landing lights. The purpose of the recognition lights is to be used in flight as a substitute for landing lights. When I flew Navajos for a freight company, I remember most of our planes had recognition lights installed at the wingtips. The reason for this is because on the Navajos, the landing and taxi lights are installed on the nose landing gear. Once the gear is retracted you did not have any of those lights available. Recognition lights then become your only remaining big bright light shining forward for other people to recognize you with as you fly through the terminal area. There is no risk of confusion since they look like landing lights and it should be obviously that if you can see that big bright headlight, that the plane is coming at you even if it outshines the little green and red navigation lights.

I was thinking more enroute than terminal, as per the spirit of the original question. Clearly, a distance recog light could be confused for a near rear navigation light.

I appreciate all the help. I always learn a lot from these discussions - but now I'm starting to get a little bit confused. Maybe I should just tell you what I'm doing. I'm trying to make my own checklists for a beechjet. The checklist that I got from Eaglesoft isn't that good (the aircraft is great though in my opinion). The beechjet has seven sets of exterior lights; landing lights, nav lights, anti-collision strobes, rotating beacon, tail flood light, wing inspection lights, and recognition lights.I thought I was pretty much straight on when everything was used, but now people are telling me that recognition lights should be used when landing lights are used and that has me confused. On the beechjet overhead panel, it specifically says, "Do NOT Use on Ground" right above the recog light switch. So, when should I use it?Here's what I have right now on the checklists:Electrictal Start Checklist:Navigation Lights onBefore Engine Start Checklist:Anti-Collision Lights OnBeacon Light On (I know that the beacon comes on before engine start. I'm not so sure about the A/C lights)Before Taxi Checklist:tail flood lights on (not actually working but still in the checklist)wing inspection onBefore Takeoff:landing lights onrecognition lights onClimb out:landing lights offtail/ wing inspection offbeacon as desired (off in clouds)Approach:landing lights ontail/wing inspection onAfter landing:landing lights offrecognition lights offPlease feel free to to offer any comments or corrections. I welcome it all.

It's not that hard, really. Unfortunately, this is the internet and people read too much or too little into anything that is written.When you power up your Beechjet.Nav lights always on.Logo lights also if at night.Before starting your engines.Rotating red beacon on.TaxiFlash taxi lights to marshallers to indicate ready for taxiTaxi light on or off to indicate movement intention.Taking the runwayTaxi light onWing inspection lights onCleared for takeoffLanding lights onStrobe lights onRecognition lights on (if you have them)All your lights should be on now.After takeoffTaxi light offClimbing through 18000Landing light offWing inspection light offRecognition light offLogo light off if they were onDescending through 18000Landing light onRecognition light onWing inspection light onLogo light on if at nightBefore landingTaxi light onThat should be all of your lights.Exiting runwayLanding light offStrobe light offWing inspection lights offRecognition lights offTaxiTaxi light on or off to signal your movement intentionsTurn them off as you park so that you don't blind the marshallersAfter engine shutdownBeacon offAll your have left again is nav lights and logo lights now.Certainly, different people will give you different ideas about this, such as whether the strobes should be on when taking the runway, or when to turn off the landing lights during departure, etc. But it really doesn't matter, what I've listed is just how the airline I fly for wants us to do it. You can make changes to that to suit your own tastes, the only absolute is that the beacon has to be on when the engine is running and the nav lights have to be on at night. Everything else is really your preference, with the goal of making yourself as visibile as possible to other people without annoying people nearby.

Just as you do not taxi around with landing lights on. You will blind people around you if you do that. It's like driving with you high beams on. Use only the taxi lights to see when taxiing. Recognition lights and landing lights are used when you are about to takeoff or land so that others can see you.

Thanks for the help.>Taxi>Flash taxi lights to marshallers to indicate ready for taxi>Taxi light on or off to indicate movement intention.I don't actually have taxi lights. You're talking about recognition lights - right? I just want to be clear.

Taxi lights are headlamp like lights similar to landing lights but less powerful, projects a beam on the ground close to the aircraft and meant to be used on the ground to see during taxi operations. Recognition are headlamp like lights similar to landing lights but often mounted on the wings, almost as powerful, and projects a beam straight ahead to increase the aircraft's conspicuity.

This isnt just small GA Im talking about, but big iron! I saw a few on approach with no landing lights. Then one with no strobes.
