Student Intros

• How many Mission Pilots? Trainees?• How many Mission Observers? Trainees?• How much experience with the GX55?• How have you used the GX55?

– Direct-to function?– Lat/Lon display?– SAR functions? Which ones?

• Have you tried out the simulator?• What do YOU want to get out of this

course?


GX55 SAR Functions

• SAR Search Patterns– Parallel Line Search: for grid searches– Creeping Line Search: for route searches– Expanding Square Search: for searches

centered around a point

• Parallel Track Route Search– to search parallel to a route defined by

waypoints


GX55 Simulator Screenshot


GX55 Simulator Operation• Point your mouse cursor at the large knob to

move left/right in the menu structure, or left/right on a data entry field. Left-click to go left, right-click to go right

• Point at the small knob to move up/down in the menu structure, or to go up/down on a data value. Left-click to go down, right-click to go up

• To press a button, just left-click on it once


GX55/Simulator Setup (1)• These instructions apply mainly to the simulator:• Click on the “Options” menu at the top of the

screen, and make sure “SAR” is checked– click on SAR if it is not checked

• Click on the “Off/On” knob• Press (left-click) the “SEL” button when prompted• Set the speed higher if you want– I suggest 300

knots• Press the “ENTER” button when prompted• The remaining instructions apply to the GX55 and

the simulator...


GX55/Simulator Setup (2)

• Press (left-click on) the “MAP” button• Turn the large knob left one click to get to the

Map Setup Page– left-click on the large knob

• Turn the small knob left two clicks to get to the SAR Map Setup Page– left-click twice on the small knob

• Press the “SEL” (Select) button...


GX55/Simulator Setup (3)• Press the “SAR” smart key (bottom of the

screen) until “SAR Map :On” is displayed• Press the “GRD” smart key until “Grid Type:US”

or “Grid Type:Basic” is displayed– We’ll discuss these two grid types and when they’re

used

• Press the “POS” smart key until “Position:DCA” or “Position:NW” is displayed– For the US grid type, we need to specify the sectional

chart we’re using—MD is covered by DCA (Washington) and LUK (Cincinnati)

– For the Basic grid type, we specify the Lat/Lon Quadrant (NW, NE, SE, SW)—we are in the NW quadrant


Questions?


SETUP EXERCISE

• 1. Set up the simulator as follows:– SAR Map: ON– Grid Type: US– Position: DCA

• 2. Set up the simulator as follows:– SAR Map: ON– Grid Type: BASIC– Position: NW– SAR Position: Latitude 40, Longitude 70


US vs Basic Grid Type

• You only care about which type you use when you do a Parallel Line search.

• US Grid is used to search quarter grids– 7.5’ by 7.5’ grid size

• Basic Grid is used to search full grids– 15’ by 15’ grid size

• Why? Because that’s how CAP specified the GX55 software!


The US Grid

• Based on gridded sectional charts• Grids identified by sectional chart

designator (e.g. DCA, LUK) and number within the chart– DCA & LUK sectionals have 448 (28 x 16) grids– numbered left-to-right, top-to-bottom

• LUK sectional overlaps DCA sectional by one degree of longitude– western four columns of DCA sectional grids are

numbered as LUK grids 25-28, 53-56, ... 445-448

– DCA grids run 5-28, 33-56, ... 425-448


GX55 US Grid Selection

US Grid designators consist of a one-to-three digit grid number (1-448 for LUK and DCA), then a one-character 7.5’ x 7.5’ sector (A-D), then a number from 1-4 indicating which corner of the sector you want to start in:

1 2

4 3


The Basic Grid (1)

• Grids are numbered by the ones digit of the latitude and longitude and letter designators for quarter-grid (30’ x 30’) and sixteenth-grid (15’ by 15’) segments

• Corners of grids are numbered as shown:

1 2

34


The Basic Grid (2)


The Basic Grid (3)


The Basic Grid (4)

• GX55 SAR Position page must be programmed with the latitude and longitude of the 10º x 10º area– SAR Position page is only shown on the

GX55 when Basic grid type is selected– SAR Position page is one small-knob click

right of the SAR Map Setup page


GX55 Basic Grid Selection

The Basic grid is selected by specifying the ones digit of latitude*, the ones digit of longitude*, the letter designating the 30’ x 30’ quadrant, the letter designating the 15’ x 15’ quadrant, and a number from 1-4 designating the starting corner

*of the NW corner for the simulator, or the SE corner for the actual GX55


Questions?


SAR Search Patterns

• Parallel Line, Creeping Line, and Expanding Square search patterns are GX55 routes created from GX55-generated waypoints– You set the parameters that tell the GX55

how you want the route generated– The GX55 creates a route comprising a

sequential list of numbered waypoints for you to fly to


Setting up a Parallel Line Search (1)

• With the MAP display on, press the “PAT” soft key (turn the large knob until you see the “PAT” soft key)

• Press the “ENTER” button...


Setting up a Parallel Line Search (2)

• Enter the Grid, Track Spacing, and Direction of the pattern you want to fly

• Press “ENTER” twice to return to the MAP display


PARALLEL LINE PATTERN EXERCISE• Set up a parallel line search as follows:

– US Grid DCA 64D, starting in the southeast corner

– Fly north/south*– 0.5 nm track spacing

• Set up a parallel line search as follows:– Basic Grid quadrant NW, position 40N, 70W– Which Basic Grid corresponds to US Grid 64?– Fly east/west*, 2 nm track spacing*The direction you fly should be a function of the winds aloft. If the winds are

from the east or west, fly east/west. If from the north or south, fly north/south.


Setting up a Creeping Line Search (1)

• With the MAP display on, press the “PAT” soft key, and rotate the small knob right one click




• Enter the Start point, track Spacing, and initial Direction for the pattern you want to fly

• The diamond to the right of the Direction means there is another page of parameters...



• To get to this page from the previous page, turn the small knob left or right one click

• Enter the Leg Length and direction of the first Turn for the pattern you want to fly

• Press “ENTER” twice to return to the MAP display


CREEPING LINE PATTERN EXERCISE• Set up a Creeping Line search from 2W2

to GAI– 0.5 mile spacing– initial direction: southeast (135 degrees)– 1.0 nm leg length– first turn to the right

• Activate it and watch the simulation...


CREEPING LINE PATTERN GX55/60 vs Simulator• In the simulator, you specify the DIRECTION as the

initial direction you want to fly, which is 90 degrees CW or CCW from the “direction of travel,” i.e. the direction of the route along which you are searchingIn the GX55/60, according to the UPSAT “Creeping Line Update” document, you specify the DIRECTION as the direction of the route along which you are searching.

• In the simulator, you specify the TURNS parameter as the direction of the first turn.In the GX55/60, you specify whether you want to start the search on the left or right side of the route.


Setting up an Expanding Square Search (1)

• With the MAP display on, press the “PAT” soft key, and rotate the small knob right two clicks



Setting up an Expanding Square Search (2)

• Enter the Start point, track Spacing, and initial Direction of the pattern you want to fly

• Press “ENTER” twice


EXPANDING SQUARE PATTERN EXERCISE• Set up an expanding square search

around 1W5– 1.0 nm spacing– initial direction: south (180 degrees)

• Activate and watch the simulation...• Tip: DO NOT FLY THE LITTLE AIRPLANE

ON THE GX55 MAP DISPLAY! Instead, make your TRacK match the BeaRinG to the next waypoint.


Marking a Point

MRK (MARK) Soft Key


MARKING A POINT EXERCISE• With the expanding square search

around 1W5 running, mark the position of 2W2 at the closest point of approach


Creating a User Waypoint• Press “NAV” to get to

the Navigation display

• Press the “DB” soft key to get to the Create User Wpt by Lat/Lon display

• Rotate the large knob to go to the other user waypoint creation modes

DB Soft Key


USER WAYPOINT EXERCISE• Let’s create a User Waypoint for P-40,

using the Create User Wpt by Lat/Lon mode– P-40 is centered at 39 38.9N, 077 28.0W

• Now create a User Waypoint 2 nm north of VPORT, which is at the NW end of the GAI-ANP flyway, using the Create User Wpt by Radial/Dist mode– VPORT is an Intersection (K-type, i.e. US), use

radial = 010 degrees and distance = 2 nm


Creating a Flight Plan (1)

1. Press the “FPL” button.2. Rotate the large knob until you see the “Press SEL to

Create a New Flight Plan” display.3. Press the “SEL” button, and enter a name for the flight

plan. Use the small knob to select individual characters for the name, and the large knob to move left and right in the name.

4. Press the “ENTER” button when done entering the flight plan name.

5. Turn the small knob to begin entering waypoints.6. Press the “SEL” button to enter the first (FROM) waypoint.7. Rotate the small knob to select the type of waypoint

(airport, VOR, NDB, intersection, user, etc)8. Rotate the large knob to position the cursor on the first

character of the waypoint ID.


Creating a Flight Plan (2)9. Rotate the small knob to select the first character of

the waypoint ID.10. Turn the large knob clockwise one click to position the

cursor on the next character of the waypoint ID.11. Turn the small knob to select the desired character of

the waypoint ID. Repeat steps 10 and 11 until the waypoint ID has been entered.

12. Once you have finished entering the waypoint ID, press the “ENTER” button to store the waypoint.

13. Press “ENTER” again to enter another waypoint, or “SEL” to indicate you have finished entering waypoints. Repeat steps 7 through 12 until you have entered all the waypoints in the flight plan.

ARE WE HAVING FUN YET?


FLIGHT PLAN EXERCISE

• Create a flight plan named “CXY-OKV”• Use the following waypoints:

– Airport: CXY– VOR: HAR– Intersection: SCAPE– VOR: HGR– Airport: OKV

• Activate it, switch to the MAP display, and watch the screen for a minute


Activating a Flight Plan

1. Press the “NAV” button2. Press the “FPL” soft key3. Turn the big knob until you see the flight

plan you want to activate4. Press the “SEL” button5. Turn the big knob until you see

“Activate?”• other options include reverse-activate (to go

home), delete, rename, copy, etc.

6. Press the “ENTER” button


Setting up a Parallel Track Search (1)• In theory, this should be simple...

– Program a flight plan– Activate the flight plan– Hit the NAV button, turn the big knob until

you see...


Setting up a Parallel Track Search (2)• But whenever I try it on the simulator, no

joy.• In theory, once you get that screen...

– Press the “SEL” button– Turn the big knob to make the side indicator

(left/right flash, and the little knob to choose left or right)

– Turn the big knob to make the offset distance flash, and the little knob to set the desired distance

– Turn the big knob to make “Use?” flash, press “ENTER”


PARALLEL TRACK SEARCH EXERCISE• Let’s try this one in the airplane.
