The higher the poygon count the more power your PC need to display the model. Multi LOD means that the MDL has more than 1 model.
The game will change to a more simple model with less detail as the aircraft/object is farther away from the player. The player probly won't see that the model has changed unless they are looking right at it when it changes. By using LODs you can put many aircraft/object on the screen with out the game becoming a slide show.
F4F4 LODs. This a gif so you may need to click on it.
The rules I use for making aircraft are no single engine aircraft should be above 5,000 poygons for the full detail/close up model and each LOD should have a polygon count drop of 25% or more. For a fighter the LODs should be LOD 100 (full detail) 5,000 poygons, LOD 75 3,750...
