767 PIC potential error questions...

Greetings! Glad to be able to join this forum. I'm a real-life air traffic controller in Jamaica and I started running sims recently to better help me understand what I'm telling pilots to do. I recently installed 767 PIC on my WIN2000 computer and I'm running the sim through FS2002. I've already installed the patch. I notice that on the default (and other subsequently installed acft) that the airspeed indicator works from zero. On PIC it starts after 30knots. Is this typical of the real acft, or is this an error? That said, if it is typical, is there a way to tweak it so that it will read from zero? Another question is this. It seems as if I can't get the acft to turn when pushing back like I can with the other acft. Is this a fault of some sort that is correctable? Thanks for the help in advance. Looking fwd to healthy suggestions/advice.
