NZ-920 Navigation Computer
Leading Particulars
Table 9-1
The NZ-920 Navigation Computer provides many varied navigation functions;
however, the primary function is to provide high-accuracy long range
lateral and vertical navigation.
To accomplish this function, the
navigation computer connects to a variety of sensors.
The prime radio navigation inputs are VOR bearing and DME distance. This
may be broken down into two categories -- VOR/DME and multi-DME. Some
DMEs can be commanded to scan two or three channels, while others supply
distance from a single channel (station). The navigation normally
optimizes the present position calculation accuracy by utilizing DME
distance data from at least two stations versus VOR bearing and DME
distance data from a single station.
The VOR bearing input is subject to
error due to bends in the beam, multipath effects, station misalignment,
etc. Using multi-DME, the bearing information from a station may be
calculated instead of simply measured.
Two types of radio (VOR/DME) configurations are supported. First the FMS
will support a system with single channel DMEs. In this system, both the
on-side VOR/DME and the cross-side DME are brought into the navigation
computer. The
second system configuration supported by the FMS is a
directed scanning DME.
In this configuration,multiple distances can be
received from a single DME receiver.
In this configuration, distances
from two stations can be utilized for
a more precise position fix.
