Playing with the Garmin GNS430/530 WAAS simulator
I second the suggestion to use the simulators to form an opinion.
I've encountered many of each in BPPP training. My impression is that now computer savvy pilots tend to get crosswise with the 430/530 less often than the 480--though there are virtuossos on each type. Rote learners struggle more with the 480. The 480 will do more but thru additional keystrokes. I do remember the instance when an engine in the Baron we were flying lunched and the new-to-480 user was trying to get to the comm flip flop! Why is that down a menu level? Pay you $$ and take your choice. BTW, the W series does command everything thru GPSS steering, an improvement over now W. If you suffer red-green color blindness, look carefully at the 480. The highlight cursor works by turning stuff green. Bill Hale BPPP instructor.

Additionally, the GPS will begin flashing a countdown-to-turn with heading message, followed by a "turn now" message. As you recall, the current GNS430 software only flashes the new heading prior to the turn and then stops flashing when the turn is to commence. Here's a screenshot taken just before the turn with the countdown message showing: http://img224.imageshack.us/img224/5...6230104xd2.jpg I then "flew" a missed approach to a hold. I thought I read in this group a few weeks ago that the new WAAS upgrade auto-sequences to the missed approach, but in the simulator it went to "suspend," similar to the current GNS feature. I was required to hit the OBS to sequence to the first waypoint along the missed. The hold was also pretty slick. The GNS430 with WAAS depicted the hold entry on its moving map, along with another "turn to a heading" message count-down. At the course reversal of the entry (in a parallel or tear-drop entry), the GPS again provided a turn-to heading countdown message and a graphic on the moving map. -- Peter |
