Thanks all,
United, Delta, Jetblue, USAirways all have SOP stating - Landing Lights On at all times below 10,000ft. Which makes a heck of a rattle in the cabin at 250kts. At night I can see how it probably makes sense, so as to be seen, but during bright daylight?
I like the "Gear Down, Lights On" BA SOP.
Knowing AA, they will probably make the landing lights Captain's discretion (which is how it is on all our fleets.)
