BOTH/VOICE/IDENT SWITCH
This switch controls the audio filtering for the NAV and ADF
receivers.
BOTH Position-When the switch is in this position, both the station
identifier and voice transmissions will be heard. TheBOTH position
is the normal position.
VOICE Position -When the switch is in this position, only voice
transmissions will be heard.
IDENT Position -When the switch is in this position, only the station
identifier will be heard.
MKR HI/LO SWITCH
HI Position-When the switch is in this position, the marker beacon
receiver sensitivity is increased.
LO Position-When the switch is in this position, the marker beacon
receiver sensitivity is decreased.
AUDIOCONTROL-FLIGHT OPERATION
1. MASTER VOLControl-Rotate to a comfortable listening level.
2. Applicable Mixer Switches-Pull "on" and rotate to a comfortable
listening level. The VHF 1 and VHF 2 volume controls do
not affect sidetone levels. The HF volume control will affect the
sidetone level on most models since audio and sidetone utilize a
common line from the transceivers. Some BF transceivers do
not have sidetone capabilities.
3. TRANSMIT SELECT Switch-Rotate to desired position.

FLIGHT MANAGEMENT SYSTEM
The Learjet 31A may be equipped with a flight management system
(FMS). The FMS is an integrated navigation management system that
provides the pilot the capability for worldwide point-to-point navigation,
as well as SIDS, STARS, holding patterns and approaches. Lateral
and vertical (descent only) steering is provided for enroute, terminal,
and approach operation.
Refer to the applicable FMS operator's manual for further details and
operating instructions.
UNS-1 B FLIGHT MANAGEMENT SYSTEM/KFC 3100 FLIGHT CONTROL
SYSTEM INTERFACE
When the UniversalUNS-1B Flight Management System (FMS) is interfaced
with the Bendix/King KFC 3100 FlightControl System (FCS) special
attention must be given to the operating modes selected on both
systems. The different configurations of these two systems can cause
the aircraft to react differently when controlled by the autopilot. The
following is an explanation and procedures for various phases of flight .
ENROUTE
The FMS may be coupled to the FCS by selecting NAV mode on the
flight director. The FCS will capture the FMS if oneofthe following conditions
are met:
If the FMS is in heading mode, the FCS will be in the forced capture
mode when NAV mode is selected on the flight directors
This means the FCS will immediately capture and turn towards
the current FMS NAV leg regardless ofcrosstrack deviation.
If the FMS is in the holding pattern mode, forced capture is
active.
If a Direct-To has been selected, forced capture is active.
If none of the above conditions exist, selecting NAV mode on
the flight director will result in an ARM condition until the
crosstrack deviation is reduced to a value which will result in
capture by the FCS. The aircraft must be maneuvered to reduce
the crosstrack by manual flight or use of flight director NAV/
HDG mode.

ENROUTE VNAV
Enroute VNAV orcruise mode is entered if a VNAV flight plan has been
created, aircraft altitude is valid and available, and the aircraft is not
more than 200 feet below the first vertical waypoint. At this point
VNAV mode of the FCS may be armed. Prior to reaching TOD (top of
descent), the altitude preselector must be set to a minimum of 200 feet
below present altitude. If this is not completed by two minutes prior to
TOD message, RESET ALT PRESELECT will be presented. During this
two minutes, an FPA CHANGE message is presented. This message
must be acknowledged before TOD in order for the FCS to capture
VNAV As the TOD is reached, the FCS VNAV mode will capture and
the FMS will enter descent mode.
In VNAV, the altitude preselector has priority over the FMS. If the preselected
altitude is higher than the FMS target altitude, the aircraft will
level off at the preselected altitude.
A VTO (Vertical Direct To) will cause the VNAV to capture
immediately.
APPROACH MODE (LATERAL)
During FMS approach mode, FMS and FCS reaction is dependent on
FMS heading mode and the sequence in which this mode and the FCS
modes are selected.
If there is a direct link between the enroute/terminal portion of the
flight plan (i.e. no GAPs), and the FMS is already coupled, the crew
need only ARM the approach on the FMS CDU and the FMS will automatically
