Ok guys, we have some planes set up with G5s wired up to 496 gps units. The G5s will display horizontal and vertical guidance from the 496 units. I understand that the G5s can also use that data for attitude calculation if it is considered to be better quality than the internal GPS data.
First, is there a "best" choice for external antenna for the 496 since the mounting point causes the little factory stick antenna to not point straight up? Secondly, I don't think these 496s have been updated since the Clinton administration and I seem to remember the WAAS constellation changing some time back requiring a bunch of these older units to need some sort of update. Did that effect the X96 series units? The units always seem to be searching in vain for a WAAS lock. If an external antenna and/or firmware update get the WAAS function working, would that max out the G5 situational awareness, or should we consider also adding an external antenna to it as well? The G5 in this particular installation do suffer from rapid and fairly extreme maneuvering which causes them to go into in flight recalibration fairly often.
