Go-Around (Ga) Button; Flight Management System (Fms) - BOMBARDIER LEARJET 40 Pilot's Manual

GO-AROUND (GA) BUTTON

The GA button is located on the outboard side of the left thrust lever.
Selection of the GA button disconnects the autopilot (but not the yaw
damper) and cancels all other vertical and lateral modes except auto-
matic altitude preselect arm. The flight director provides a wings level
command bar display in the lateral axis and a fixed pitch-up vertical
command. The pitch command does not guarantee that the go-around
airspeed will be achieved. If used on takeoff, the pitch attitude will not
guarantee achieving the V .

FLIGHT MANAGEMENT SYSTEM (FMS)

The UNS-1E is a fully integrated Flight Management System (FMS).
The FMS provides centralized navigation sensor control, flight plan-
ning, lateral and vertical flight guidance, steering enroute, terminal and
approach modes of operation. Database management, fuel manage-
ment, and maintenance functions are also provided by the FMS.
The UNS-1E accepts position information from up to five long-range
navigation sensors as well as DME, VOR, or TACAN sensors. The data
from these sensors is used to determine the best computed position.
The UNS-1E incorporates an internal GPS sensor with Receiver Auton-
omous Integrity Monitoring (RAIM) as a standard part of the FMS con-
figuration. The FMS interfaces with the IC-600s for a transfer of
information to the FMS and lateral and vertical steering commands
back to the EFIS and FD/AP.
If a single FMS is installed, it can receive ADC, AHRS, EFIS, and AP
data from either IC-600 but will use the #1 IC-600 as the primary source.
If dual FMSes are installed, FMS 1 will use the #1 IC-600 as the primary
source and FMS 2 will use #2 IC-600 as its primary source. With dual
FMS installation, the pilots can use either FMS as the navigation source
on their PFDs/MFD. In the material that follows, the FMS unit will be
referred to as the Control Display Unit (CDU). The CDU contains a col-
or, flat panel display, ten Line Select Keys (LSK) and dedicated function
keys.
The FMS is powered from the left essential bus by a 5-amp circuit
breaker labeled FMS located on the pilot's circuit breaker panel (AVI-
ONICS [NAVIGATION] group).
