5.12. VIEWING THE KLN 94 SOFTWARE STATUS (AUX 14
PAGE)
The AUX 14 page (figure 5-93)
shows the application software revi-
sion (line 1), the software status of
the KLN 94 host computer (line 2),
graphics engine computer (line 3),
the GPS receiver (line 4), aeronauti-
cal database (line 5), and land –
cartographic database (line 6).
5.13. THE FUEL MANAGEMENT (AUX 15 – AUX 19)PAGES
Certain models of fuel management computers manufactured by Shadin
Company, ARNAV Systems, Inc., and Sheltech Ltd. May be interfaced
with the KLN 94. The primary benefit of having the KLN 94 interfaced with
a “real time” fuel management computer is that the system can continu-
ously compute the amount of fuel required to reach the destination and
the amount of fuel that will be on board upon reaching the destination. The
concept is the following. The fuel management computer continuously
sends the rate of fuel flow and the amount of fuel remaining to the
KLN 94. The KLN 94 continuously calculates the aircraft’s distance,
groundspeed, and estimated time en route (ETE) to the destination way-
point. The fuel required to reach the destination waypoint is the ETE
multiplied by the current rate of fuel flow. The amount of fuel that will be
remaining at the destination is the amount of fuel presently remaining
minus the fuel required to reach the destination.
CAUTION: The KLN 94 fuel calculations are based on the present
rate of fuel flow, the present groundspeed, the present distance to
destination along the programmed route, and the amount of fuel
presently remaining. Before take-off, the fuel flow computer must be
properly initialized with the amount of fuel on board (FOB) the air-
craft. For some Shadin fuel computers without display units, you
may enter the initial FOB during the KLN 94 Turn-on and Self Test
(see section 3.2). Since many factors influence the required amount
of fuel to reach the destination, it is the pilot’s responsibility to view
the fuel management pages often to check for any significant
changes. Some factors affecting the amount of fuel required are
power changes, altitude changes, headwind/tailwind component
changes, fuel/air mixture adjustments, and routing changes.
The AUX 15 – AUX 19 pages are used to display fuel management infor-
mation for KLN 94s interfaced with compatible fuel management
computers. If there is no fuel management computer interface, these fuel
management pages are not displayed.
