vertical speed, use the outer knob to
position the cursor over the vertical
speed field (figure 5-10). 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 desired
vertical speed is reached, position the cursor over the vertical speed field
and VNAV will commence. When VNAV begins, the top of the page dis-
plays an advisory altitude. Descending at the vertical speed displayed on
line 4 should keep you very close to the VNAV advisory altitude, but you
may need to make slight adjustments to stay right on pace.
A better way yet to initiate VNAV is to program a desired vertical speed to
use for the descent, after you have entered the desired altitude, waypoint,
offset, and groundspeed. To program a vertical speed, do the following
step:
6. Use the right outer knob to move the cursor to the vertical speed field,
and then enter the desired value (figure 5-11). Vertical speed may be
selected in increments of 100 feet per minute or 10 meters per
minute. If the time to begin your
descent is greater than one
hour,
Vnv Armed will now be
displayed on the top line of the
page. If the time is less than one
hour, the top line displays a
countdown to the time to begin
the descent.
7. Return to any desired page for now by pressing the
A
button once.
Alternatively, you may turn off the
B
and use the outer knob to
change pages. Approximately 90 seconds before the time to begin
descent, the message prompt will flash. When you view the Message
page, it will display
Vnv Alert . This is notification for you to view the
NAV 1, NAV 4 (map), or ALT 2 page because it is getting close to the
time to begin your descent. All three of these pages are capable of
displaying VNAV data.
8. When the countdown timer
reaches 0:00, the time will be
replaced with an advisory alti-
tude (figure 5-12). Begin your
descent at a rate such that the
altitude displayed on your altime-
ter matches the advisory
altitude.
