Pilot's Manual
The
fuel management function of the FMS allows the pilot to plan fuel
requirements while
on
the
ground
.
Pilot-supplied data and inputs from
the airplane's fuel flow sensors give the FMS the
necessary information
to calculate and display significant real-time fuel management
information throughout the flight .
For a detailed description
and operation of the FMS, refer to the
"Collins Pro Line 4 Avionics System For The
Learjet 60" Pilot's Guide
(P/N 523-0777003), or the UASC Operator's Manual as appropriate
.
WEATHER RADAR
A weather radar system is installed to give the pilot a pictorial repre-
sentation of the safest possible flight path during adverse weather con-
ditions . The single
unit X-Band weather radar provides data from
atmospheric moisture and ground features
.
The
resulting radar
"pictures" are displayed on the MFDs . Terrain mapping is possible
with the
radar,
and
with practice, the pilot will be able to identify coast-
lines, large rivers and lakes,
mountainous areas and cities . As the radar
system becomes more familiar, it may be used
to
verify position, track,
ground speed, altitude and attitude as well as for weather avoidance .
The
radar can be operated in a split mode or sync mode . In the split
mode, both pilots have
the option of placing the radar in different mode
and range settings on alternate
sweeps .
This gives
the appearance of
two independent radars . In the sync mode, both sides show
the same
radar display . Some installations include the capability to detect
precipitation related turbulence .
Control of the weather
radar is accomplished from the associated Con-
trol Display Unit (CDU) in the
pedestal
. Primary
stabilization for the
radar is obtained from the left Attitude Heading System (AHS)
. Radar
stabilization is automatically obtained from the right AHS if the left
AHS fails .
For a detailed description and operation of the weather radar
system
refer to "Collins Pro Line 4 Avionics System For The Learjet 60" Pilot's
Guide (P/N
523-0777003) .
