Wingtip landing lights

Hello all,

I'm starting to think about landing/taxi lights and whether to go with the Duckworks-style square leading edge lights, or the CreativAir-style combo of smaller round lights and LED position lights.

I'd really like to hear some comments from anyone who has flown with the CreativAir combo system. Are the landing lights bright enough? Do they "wash out" the LED lights surrounding them?

Thanks in advance,

Dave

You'd be better off with the Duckworks landing lights and these...

Ok, those are really cooool. . . But what are they, where do I get them, how much do they cost? Are they green and red serving as the nav lights or is that just my imagination on the color of the light in your photo? If they are your nav lights I have got to get some of those. Please give me some info on where to get them.

They are Nav lights. One Red and one Green. I offer them for $300 a pair, plug and play no building.

TRIM paint

I just gota know about that paint trim your using on those lights Jeff ?


Danny..

You might heck out this website too. This is what I'm going to use for landing lights. I saw several sets of these installed in RV's. They all told me they put out plenty of light and they fit in the wingtip. I have two Duckworth wingtip lights I would sell worth the money if you decide to go that way. They are fine but I just decided I didn't want to cut the leading edge skin to install them. http://www.rmdaircraft.com/

I would also be very interested to know of anyone who has firsthand flying experience using wing tip landing lights. I'm getting close to the stage of needing to decide. When I was at Van's getting my demo ride, I asked Gus about them. The short answer was he thought they were great for the -10 because the wingtips/plexiglass lenses are large, but not very good for the 2-place RV's because the wingtip lens is too small to allow the landing light to aim inward enough to be useful. Plus, the relatively small size of the wingtip made the interference with the strobe and/or position lights more noticeable in ways that it was not with the -10. I have no firsthand experience myself, but please let me know if you have. I'd love to not have to cut up my leading edges, but plan do so within the next week or two unless I hear otherwise from successful users (fliers) of the wingtip versions.

I painted it with a paint called Alclad II Lacquer. It is a paint designed for painting the back side of glass and looks like a mirror on the opposite side. However the clear tips are made from Lexan which is flimsy, scratches easy and has horrible optics. Sad thing was when painted with the Alclad II, it attacked the plastic and did not look like a mirror. I will soon be offering these tips in Plexi-Glass and they will look much nicer.

Jeff,

Will there be any of your lighting packages at Osh? Anyone flying with your lights?

The fuse stand is working great! Very glad I bought it from you.

Take care,

Jim

Good points, Steve. We had a set of RMD wingtip lights on our Archer, and with the nose landing light off we had a big dark spot in front of the airplane for the very same reason that Gus mentioned.

One of our local -8 builders has a set of the CreativAir combo landing light/LED nav lights in his wingtips. With the landing lights on, the nav lights seem to be washed out and more difficult to see - and those LED lights are pretty bright. That's on the workbench, though, and I'd like to see how they work in real-world ops.

Gee, I think I'm talking myself into a pair of Duckworks lights...

Just to play Devil's Advocate; imagine looking at an aircraft (at a distance) with the Duckworks lights AND the Creative Air nav lights on in the wingtips. The landing lights are still going to be a lot brighter than the nav lights so even though the landing lights are a couple of feet away from the nav lights, the landing lights will still most likely "wash out" the nav lights because of the difference in brightness.
I'm thinking that when the landing lights are on, the nav lights are kind of superflous anyway for determining orientation and direction of the aircraft.

Well...

I looked at the pictures on Duckworks' website. There seems to be a bit of separation between the landing and nav lights. But you're certainly right that if you're looking into the landing lights, nav lights aren't your primary concern.

LED position lights

Before we get too excited about LED lighting, there may be some regulatory issues that need considering.

In the great white north, *conforming* position lights are a requirement for night flight. Since our 'CARS' are based on US 'FARS', I'd recommend digging through the requirements. I've quoted the Canadian requirements.

Please note, that the appendix referenced is very specific in the technical requirements. You CANNOT slap on a green light, a red light, a tail light and be legal for night flight.

In addition, LEDs exposed to the environment will fail by way of corrosion, and not likely burn out. Some means of replacement should be considered. It could be expensive to replace the entire module.

Whelen makes certified LED position lights at Whelen prices (i.e. expensive).

In the end, LED's are a great idea... but you must certify your installation to be legal for night flight...

As for landing lights... I've landed several times without landing lights, and I consider them a convenience feature, not an essential requirement (but must have runway lights!) However, I will use landing/taxi lights during the day in wig-wag fashion for anti-collision.

Now, what we really need are LED landing lights!

Power-driven Aircraft - Night VFR

(1) The position lights and anti-collision lights referred to in CAR 605.16(1)(k) shall meet the requirements set out in Schedule 1 of Appendix I of this standard, and shall:

(a) comply with the standards of light distribution, intensity and colour, and the flashing characteristics, where applicable, in accordance with the Airworthiness Manual;

(b) be installed in accordance with the requirements set out in Chapter 551 of the Airworthiness Manual; and

(c) not cause glare or other annoyance to a flight crew member to the extent that the person's ability to perform duties safely is affected.

(table deleted)

Good point, Vern.

I did a little digging in the US FARs. FAR 91.205 requires "approved" position and anticollision lights for night VFR/IFR operations. In this case, my guess is that "approved" means certification via a TSO, STC or some other airworthiness approval process.

But can a DAR or FAA airworthiness inspector legally approve an LED lighting system as part of an amateur-built airworthiness inspection? Who knows...

LED Position lights

I've been watching this thread with interest. It seems that Dave and Vern have really hit home here. I just did a little internet shopping and found to put together the whole position/strobe light system, incuding the A500 tail/strobe combo light, cheap strobe kit and LED wing light system (assembled), you're gonna spend about $730.00. Van's sells the #6 light kit for $780.00. Is it worth saving $50.00 only to find out the system you've installed is not legal?? Not to me!
Seems like a lot more reg investigating is in order.

Creativair wingtip landing lights

I would like to hear from anyone regarding their experience with Creativair's wingtip landing lights. What do you like about them? What do you not like about them? It appears that the landing lights that Van's is now offering for the RV-10 are very similar to the Creativair offering. Mine will be going in a 9A, so any input on that application would be greatly appreciated. I like the looks of the Creativair lights, but the standard seems to be Duckworks lights. Can anyone offer a comparison? I don't think I'll go the HID route because I want to use a wig-wag flasher, even though the HID's are brighter and use less power - they're just too expensive for my blood.

Also, is there anything I need to watch out for if I use Van's "lighting system 6" for a strobe/position light kit? I'm sure Van's has all the bases covered with this system when using sheared wingtips, but there's nothing like advice from someone who has already been there.

Thanks in advance for the help.

Ditto...LED Landing lights!

With the plenty of LED torches and LED car headlamps coming on the market this should just be around the corner. This could be a great opportunity for the small time entrepreneur.


Just imagine a single integrated NAV & LANDING LED wing tip combo ala Creativair style with a nice shiny surface as shown by RV7_A above in his pictures. That would be so cool everyone would drool over your lights

Thermos,

What does "approved" mean? Can we safely say that when we are awarded out Airworthiness Certificate, the feds are "approving" the entire package as experimental category and thusly the lights are ultimately "approved".

I dunno? I am tempted to find out, at the cost of having to change the LED's out at a later date if I must.

Also, I agree that the landing lights are just that and landing lights are not required, but nevertheless... nice to have. Also nice to have is a good lamp to taxi with. This is especially true at an unfamiliar airfield!

Hmmmm, I wish SOMEONE would make up my mind!

I am getting distracted with all the facts!

I think simply verifying that your lights meet the FAR requirements is sufficient and should be a relatively easy task since the requirements are very specific and detailed. It looks to me like all you would need is a light meter, a protractor and a darkened hangar ( We are experimental aircraft builders after all).
I don't think they (the lights) need to be certified.
I also don't think the DAR or FAA examiners carry light meters to assure themselves that your lights meet the FAR requirements but they might appreciate the light intensity map that you generated above to convince them of the fact should the question arise.
It may even be possible that some of the suppliers have already generated such a map that might be available if you ask.
I intend to roll my own led nav lights and will certainly generate the intensity map to verify to myself that they meet or exceed the minimum regulations for intensity versus view angle.


-Mike

The DAR/FAA inspector does not certify the lighting system per sey. Your Operating Limitations will state that "After completion of phase I flight testing, unless appropriately equipped for night and/or instrument flight in accordance with part 91.205, this aircraft is to be operated day VFR only." This puts the monkey on your back. If the aircraft is apporpriately equipped, you may fly at night.
