Panning is another map page function, which

allows you to move the map beyond its current limits
without adjusting the map scale. When you select
the panning function—by pressing the small right
knob—a target pointer flashes on the map display. A
window also appears at the top of the map display
showing the latitude/longitude position of the pointer,
plus the bearing and distance to the pointer from your
present position.

1.   Press  the  small  right  knob  to  activate  the 

panning target pointer. 

2.   Turn the small right knob to move up (turn 

clockwise), or down (turn counterclockwise). 

3.   Turn the large right knob to move right (turn 

clockwise), or left (turn counterclockwise). 

4.   To cancel map panning and return to your pres-

ent position, press the small right knob. 

When the target pointer is placed on traffic, the

traffic range, altitude separation, squawk code (if avail-
able), and tail number (if available) are displayed. The
traffic is identified as follows: 

TA: Traffic Advisory. This is traffic with 500 feet, or

less, of altitude separation that is converging or
maintaining altitude separation.

PA: Proximity Advisory. This is traffic with 500 feet

of altitude separation that is not a TA.

TRFC: Other traffic.

The Ryan TCAD Setup Page is accessed from the

Traffic Page. The TCAD Setup Page allows you to
configure traffic data. The definitions of the available
options are listed in the TCAD Pilot’s Handbook.
