A patch for landing lights is floating around on IRC. (Haven't tested it yet.) Is this an aircraft modelling issue, or something more fundamental? I.e. do I just need to add some light objects to my aircraft model and some nasal code to switch them on? If so, then I think it would be fairly safe for v1.0, as it would be on a per-aircraft basis.

Presumably this is going to cause some dull rendering issue if we ever had landing lights enabled in a mult-plane environment? Good point. Perhaps the non-local models should have a luminous fake light like the other lights in fg for this reason. In the real life you don't see others' landing lights light cones unless you taxi by while they land or smth like that. Finally, on a more practical note, I assume that landing lights work a bit like car headlamps - i.e. you switch them on during landing and they illuminate the runway infront of your so you can see when to flare? In traffic congested areas, e.g., when approaching an airport, one is encouraged to switch the landing light on for being seen better, even during daytime. I'd call this the main actual purpose of the landing light. (The positional lights, OTOH, have no practical use in daylight). When landing (I'm talking about light planes here), the landing lights are good for barely illuminate several tens of meters in front of you. Pilots are trained to land on lighted runways without the use of the landing lights (by using peripheral vision and the runway perimeter lighting to judge the depth).

I'll probably make a generic model that can be placed on other aircraft too. Where are they located on the C-172, C-182, C-310 - on the wing or on the nose like I've seen in pictures of a C-210? -Stuart ___ To help you stay safe and secure online, we've developed the all new Yahoo!

I own the pilot info manuals for various model C-172 planes, so I can look it up and even scan for you the relevant drawings. Will do in the evening.

It varies depending on year of production, model and production location ie: France / US. For example, Our default '81 172p would have a single unit in the nose fairing under the prop. (although the texture seems to suggest the earlier model) The earlier 172p's would have two larger lights behind a perspex screen in the leading-edge of the port wing around the last rib before the wing tapers. One light (the outboard one) was angled to illuminate the area immediately infront of the aircraft when on the ground (taxi) and the other (inboard) was angled to illuminate the nominal glideslope (landing).
