Dayium!!
...Hey Kevin what do you know.....Your suggestion was a "Sucessful"...
1. Did set the Service 1 for Catering at R1 the vehicle got in position and when opening R4 the crew at R1 did its thing correctly but of course Crew figure ran through the shutted door!!...Ouch!..must to hurt!!..lol
....lol oh and R4 opened & closed with the Shift E+2 command.
2. Did set Cargo1 with Belt Loader at the R1 position and the same Belt Loader at R4.
3. When "Requested Loading" Jetway attached the L1 and prompted Shift E+2 to open R4 again then Shift E to open L1
4. Only One Loader appeared and positioned it self at R4.
5. Once the Loader at R4 departed I prompted Shift E+2 and R4 did closed individually and furthermore L1 closed by Shift E individually as well.
Xtra-Note:
a. At time of Request Loading the luggage train for the R1 area does appeared and stopped at the position where the loader would be and then departed
b.A few minutes later a 3rd Luggage Train shows and positions at R4, circles around and then departs.....At that moment the "Loading Completed MSG" shows on the screen. Have no idea how to configure that to stop it.
For now your suggestion did the trick needed, I think its better now than nothing. Thanks so much!
