FSXNP...
Seriously, you got working AoA lights (green/amber/red) on the nosegear?! Figures, just before we are supposed to get the SuperBug. Still, great work!
My answers to your questions:
1. No, not simultaneously. Id say for carrier landings/FCLPs, pilot simply doesnt select "landing light".
2. Dont know for sure. Guessing it activates on landing gear lowering. Ties into above answer in that its always active. However, at civilian/airforce/non-FCLP field landing, the landing light is activated.
