Is there supposed to be night lighting (tail)? cause I don't have any. And how do I stop GA and CARGO a/c from being parked at the gate?

For all your AI parking questions, you can refer to this "bible" of rules :)http://afcad.projectai.com/documents/FS2004Parkingv6.htmlIt requires a bit of editing inside your AI's aircraft.cfg but its no biggie.Conserning nightlighting of AI planes, it really depends on mostly if there is a night light mask included with the textures (usually 2 files in i.e. PAI or FSP texture folder instead of just one).

night lighting need special textures in format : xxxx_l.bmp ; you need one in each aircrafttexture folder or better only one for each type of aircraft in fs2004 general folder texture (e.g. fs2004texture). you can have special light texture files for cargo planes (without windows) in each cargo planetexture folder.PAI has released complete set of night textures :FS9_PAI_Nightlights_1.zipFS9_PAI_Nightlights_2.zipto extract to fs2004texture and you can remove all xxxx_l.bmp in all PAI aircraft texture folder BUT cargo ones.UT night textures are same as PAI
