Hi Bruno, By Standard do you mean the Air France MTL mandatory model? I can't see a "Default" plane in the MTL, they are all airline specific.
My MTL Library has:
Air France, Austrian, Avianca, Continental, Cathay, Aero Campeche, Swiss, Delta, Finnair, Iberia, LAN, Northwest, Olympic, Qantas, Sabena, Saudi, Aerotamatan, Tropic Air, TAP, Viacao Aerea Rio Grandense & Viacao Aerea Sao Paulo.
I will probably fly the Delta Livery as it is the oldest US airline there and I guess we want to keep the theme.
Cheers,
