    You would think that DC3's or B17's must have had a way to do this. A brief search turned up nothing, but I am sure a more thorough search would find something applicable. Sensing the angle of the airplane and adjusting the light automatically would seem tricky, but sensing the speed from the pitot and making an automatic adjustment, or putting a switch on the tail wheel might yield a system that is worth implementing. But Keep It Simple. Remember that the main long-throw lights are used when the tail and airspeed is high. By the time the tail is on the ground, you might not need much. -------- Eric M.

    Subject: Re: Landing Light Aim
    So, maybe the light could be aimed by tracking the pitch trim. Simpler and maybe even lighter to put two lights on the airplane? One for taxi and one for landing. You get a bit of redundancy too. Old recipe for success. Moving parts = yuck. Finally, I would have guessed aiming for landing attitude might be better, as once you're in three point attitude you're not covering ground nearly as fast so maybe don't need to see as far/well. I do understand that your desire for visual acuity increases while close to the ground.. Cheers, Matt- On Jun 28, 2013, at 7:59 AM, "Eric M.

    I must say that I agree with "Old Bob" that the light should be adjusted for straight ahead with the tail on the ground. If you adjust for straight ahead with the tail high you will be lighting the tree tops during taxi, which greatly decreases the utility of the light. If the light is adjusted somewhat low, you will still be able to see the ground for both approach to landing and taxi. This is not optimal for all phases of flight and taxi, but IMHO it's the best compromise for one solidly mounted light. Roger -- Do you have a slow PC?

    Subject: Re: Landing Light Aim
    Good Morning Eric, Actually there were retractable landing lights which did provide the pilot with the capability of adjusting the beam up or down, but the majority only had one position where the light was on. In my past, the only two airplanes I flew with the adjustable lights were the Bamboo Bomber (Cessna Bob Cat) and the Douglas DC-6/7 series Both of those series' aircraft had one switch that extended or retracted the light and it had a center position by which the light could be stopped. They also had a separate on/off switch for the bulb itself. Unfortunately. If you retracted the light and failed to turn it off it was not noticeable from the cockpit unless you flew into a cloud where the blast of light would make it obvious. The vast majority of retractable lights I have used just went up or down. No stopping in between and the light came on shortly after it vacated the housing and went off shortly after the retraction process was initiated. I suppose that a bit of rewiring could make any of them work like our old DC-6/7 lights did. The DC-3s that I flew had very nice fixed landing lights mounted in the leading edge of the wings. Since I just flew for one company, I have no idea whether other airlines had their airplanes differently equipped. One thing for sure, we tried to use the landing lights as little as possible on the ground because they got too hot and would burn out the bulbs prematurely. The fixed ones would also warp the plastic leading edge cover if used on the ground. Landing lights were normally off for all taxiing. If the need arose, just a short blast was used.

    This is a bit of a long shot, but here goes... I'm an AeroElectric lurker. I work in the factory automation business. One of my customers called me a few minutes ago looking for 3000 Panduit P14-6FN-M. That is a fork terminal with a non-insulated barrel for #16-14 wire. He needs these tomorrow, or, at latest, Monday. I don't normally sell stuff like this and his regular source is out. We've checked Newark, Mouser, Grainger, and Allied..... Any ideas?

    I see them offered at Mouser, Digikey, Grainger, etc...but they're either out of stock or in one case, only 77 left! But I did find this one at Sacramento Electric Supply, no indication of how many are in stock, but it might be worth a look-see: http://store.sacelec.com/index.php?l=product_detail&p=7699 Harley ----------------------------------------------------------------- On 6/28/2013 7:25 PM, jhausch wrote: > > This is a bit of a long shot, but here goes... > > I'm an AeroElectric lurker.

    Thanks for the additional input everyone! This particular application won't have any provisions for in-flight adjustment, but the variation in replies here has helped establish the range of ground adjustment that I will provide for.

    Does it have to be that exact part number? These look like they would match: http://www.elecdirect.com/product/79c0d8db-bf28-44a1-a7de-b5a482e01f42.aspx They say 3-5 day shipping, but maybe they can do something special for you if you call them?

Given the low cost, small size and low energy requirements, have you considered separate landing and taxi lights. Even the trikes often have separate lamps. Bob . . .

    Hey guys, Thanks! We'll give those a try. Yes - the usual suspects are all out of stock. We knew about the 77. He needs to use a 16 AWG wire with it. I suggested looking for other fork terminals or perhaps different AWG ranges... Read this topic online here: http://forums.matronics.com/viewtopic.php?p=403596#403596
