2. The cursor should be on and over the selected altitude field on
the right side of line 2. If the cursor is not on, press B .
3. Enter the desired altitude of 1900
feet in the selected altitude field,
using the right inner knob. The
altitude may be entered in 100
foot or 10 meter increments (fig-
ure 4-60).
NOTE: If the KLN 89(B) does not have an altitude input, the indicat-
ed altitude field on the left side of line 2 will be preceded by a
colon (:), indicating that you should manually enter the aircraft’s pre-
sent altitude, as well as the desired altitude.
4. Use the right outer knob to move
the cursor to the offset field adja-
cent to the active waypoint
identifier. Entering an offset
allows you to reach the desired
altitude a specified distance
before or after reaching the way-
point. If you wished to reach a certain altitude 5 miles after
passing a waypoint, you would enter +05. In this example you
desire to reach traffic pattern altitude two nautical miles prior to
the airport, which allows sufficient time to slow down and prepare
for the landing. Enter an offset of -02 nm (figure 4-61).
5. Use the right outer knob to move
the cursor to the groundspeed
(GS:) field. Use the right inner
knob to select your anticipated
groundspeed for the descent
(figure 4-62), remembering that it
may increase from your current groundspeed when you start
descending.
Notice that the bottom right corner of
the ALT 2 page now displays a verti-
cal speed. If you wish to start your
descent now using the displayed ver-
tical speed, use the outer knob to
position the cursor over the vertical
speed field (figure 4-63). VNAV oper-
ation is initiated by bringing the cursor over the vertical speed field.
Or, by leaving the cursor off of this field, you may watch the required
vertical speed increase as you fly toward your waypoint. When the
