9.1 PRIMARY MEANS OCEANIC/REMOTE

OPERATION

ORS 04 and later versions of the KLN 900 provide for pri-

mary means oceanic/remote operations (per FAA Notice

8110.60).

When the KLN 900 is to be used as a primary means of

navigation for oceanic/remote operations (including mini-

mum navigation performance specifications (MNPS) air-

space), you are required to verify that FDE is available for

the oceanic sections of your flight prior to departure.

(Please refer to section 5.8.2 for more information about

FDE.) The PreFlight Version 2.0 (or greater) software

can be used to perform the required FDE prediction for

the oceanic sections of your flight. The PreFlight soft-

ware program runs on a Microsoft Windows-compatible

personal computer and includes the capability to transfer

flight plans and waypoints to and from the KLN 900 using

an interface cable. Instructions for ordering the PC inter-

face cable (i.e. the PC Data Loader Kit) appear on the

order form in Appendix F.

During your flight you should turn to the KLN 900's

MODE page and select OCEANIC: ON (figure 9-2) at the

beginning of the oceanic/remote section of your flight.

Since oceanic mode does not require the same level of

satellite integrity monitoring as do the other modes of

flight, oceanic mode effectively increases the availability

of RAIM and FDE. In oceanic mode, the CDI sensitivity is

5 nmi full scale, unless manually changed by the pilot.

Finally, at the end of the oceanic/remote section of your

flight , your should turn to the KLN 900's MODE page and

select OCEANIC: OFF (figure 9-3).

If you have an approach loaded and come within 30 nau-

tical miles of the destination airport, the KLN 900 will

automatically switch from Oceanic mode to Approach

ARM. If the KLN 900 is in either Approach ARM or

Approach Active, the OCEANIC mode will be turned OFF

and the OCEANIC selection on the MODE page will not

be user-editable (figure 9-4).

NOTE: The PreFlight software program (described in

Appendix F) allows you to predict RAIM and FDE cover-

age along a flight plan. For more detailed information

about B-RNAV, FDE, Oceanic mode, and operating the

PreFlight software, please refer to the PreFlight User's

Manual which is stored on the PreFlight diskettes.
