Add weather and any abnormality and you can easily make a mistake. The kind of mistake that gets you a “call this number “ from the controller. With the software capabilities of VNAV however, it’s a matter of programming the FMS and monitoring the autopilot’s performance, dramatically reducing the chances of a “close encounter” with the FAA. Plus, using VNAV allows

For me, this is most helpful during taxiing, when the ground controller (while pissed off and eating potato chips) says, “November 921 X-ray Tango, right on Alpha, left on Charlie, Delta, Romeo, cross 22 Left, hold short of the right.” All I have to do is quickly write this down, scroll in the range on MFD map, and follow my little magenta airplane.

And for about $100,000 extra (in the case of the Citation M2) you can buy the ultimate: TCAS2. This system analyzes the relative position and speed of each transponder-equipped airplane and actually commands you to climb, descend, or monitor your present altitude until the conflict is resolved.
Don’t think it’s worth a hundred grand? I didn’t until recently. Descending into Mesquite, TX (KHQZ) in visual conditions at 3,000 feet, Regional Approach called out traffic 500 feet below. I saw it on the display at 400 feet, closing, and not in radio contact with the controller. First, came the “TRAFFIC, TRAFFIC” call. Now, less than a mile away, it was time to do something. Simultaneously with the controller’s order to climb 1,000 feet , my PFD lit up with red command bars showing an immediate climb and the loud instruction, “CLIMB, CLIMB.”
