Simple questions about sounds

i have few questions about the sound engine in FSX.
  1. viewpoint=1 and viewpoint=2 they set if a sound can be heard from VC or from spot view. What if i would like a sound to be heard the same in both views?
  2. AI airplanes sounds can have startup and shutdown sounds?
  3. AI airplanes can have landing gear sounds and touchdown sounds? (i didnt manage to make it work, flaps does)
Thanks to anybody would help me!!
EDIT> I double checked, no landing gear sounds and no touch down sounds :(
EDIT2> no shutdown or startup sounds as well :(:(
