3. BASIC GPS OPERATION
3.1. COVERAGE AREA
The KLN 89(B) 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 4.10 , “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 89(B)!
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 89(B) it always “wakes
up” in the Leg mode. Only the Leg mode is described in this chapter.
In this mode the KLN 89(B) 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 situa-
tion indicator (HSI) or CDI is five nautical miles (full scale sensitivity)
left and right in Leg mode. The other modes are described in
section
4.7 and chapter 5 .
