GNS430 vs. GX60 - missing functions

So do you fly anything except G1000s? If so, then how do you program in the
grid tracks? Do you have a formula for calculating the grid-edge waypoints?

But back to any of the non-GX 50/60 class; does the aircrew just
calculate
and program in the WPTs by hand, or do they use the old pencil and chart
method to layout the grid track?

In the G1000 the observer takes command of the right screen while
taxiing out and programs in a way point named Grid#A/B/C/D, etc.
So he creates a WPT called 123A, 123B, 123C, 123D, etc. He does this
by looking at his gridded sectional and figuring the lat/long. If he
makes a mistake, its obvious on the screen. If he's lucky someone else
has already searched that grid and the WPT is already there! . He
then creates a flight plan that goes direct to one of the points and
then goes through each point. That flight plan is stored in the FPL
database for the pilot to pull up. We don't do much hand flying in the
G1000 planes, the autopilots are pretty awesome.

For CAP I only fly the G1000 (it's our squadron's only aircraft).
However, any GPS should allow you to create WPTs by lat long (which is
what we do).

The vast majority of CAP's 500+ aircraft fleet are not G1000 but the old round guage panels we all know and love, To the best of my knowledge all the fleet is equipted with GPSs. Since each was equipted with the latest and greatest panel when it was built, what's in each plane varies widely. What's taught at CAP's National Emergency Services Academy Mission Aircrew School is to plan your search on paper. The observer finds the lat/long of the entry and exit points. Since most search legs are on cardinal directions (N-S, E-W) these points define the search area, The pilot flys the airplane to a point several miles outside the search area on the extended first leg. Holding either the lat or long steady, the first leg is flown. Once out of the search area on the first leg the pilot makes approximately a standard rate 180 degree turn. That positions the plan one mile to the side and close to the lat or long of the next leg. With a little fine adjustment to the lat or long the search areaa is entered and the next leg flown, This process is repeated until the search area is covered. All that is needed is some way to see your current position's lat/long. And all the GPSs can display this. Very straight forward process.

Yes Chuck, I've been a rated mission pilot for years, but I'm not current.
In our Wing, mission checkouts now include demonstration of integration of
modern GPS technology into the search patterns. For example, I must
demonstrate how to set the GX50/60 series that are in most CAP aircraft for
Creeping Line, Parallel Track, and Expanding Square searches from an Initial
Point. I must also demonstrate using the GPS to compute and display the
standard grid search that you described.
Unless the route of flight of the target aircraft is one of four compass
headings (actually true headings) - North, South, East, or West - the search
pattern used could easily not be aligned with latitudes and longitudes.
Additionally, rather than fly several miles outside the pattern entry point,
many mission pilots equate that fix similarly as we do a holding fix. We
approach it via the most direct and expeditious route and then execute the
proper "holding pattern entry" to align us with the inbound heading -
essentially a 1/2 turn hold prior to entry into the grid. Most usually this
contributes to more time in the search box and less in transit.

My whole point in starting this thread was to determine if these SAR
capabilities are peculiar to the Apollo GX50/60 series or should I have been
able to find them in the Garmin 400/500 series. Apparently this feature is
unique to Apollo,
