3. BASIC GPS OPERATION
3.1. COVERAGE AREA
The KLN 35A was designed to provide worldwide navigation cover-
age from North 74° latitude to South 60° Latitude (figure 3-2).
Outside this area, magnetic variation must be manually entered as
discussed in
section 4.6 , “Operation Outside the Primary Coverage
Area”. See section 2.2 for the data base geographical regions.
3.2. TURN-ON AND SELF TEST
Well, it’s time to get down to business and actually use the KLN 35A!
Figure 3-1 can be folded out and used as a reference during the
following procedures. This is especially handy if you’re learning while
away from your GPS. The steps below take a lot of words to explain,
but before you know it, you will be “flying” through them.
NOTE: When power is applied to the KLN 35A it always “wakes up”
in the En route-Leg mode. Only the En route-Leg mode is described
in this chapter. In this mode the KLN 35A performs great circle
navigation (the shortest distance between two points located on the
earth’s surface). The course deviation output displayed on the unit’s
internal course deviation indicator (CDI) and provided to an external
horizontal situation indicator (HSI) or CDI is five nautical miles (full
scale sensitivity) left and right. The other mode is En route-OBS and
is described in
section 4.5.3 .
