t’s the end of the second sweep. It’s a little bit confusing toward the end but from this point the
INS/EGI does its magic and you have some time to check systems, prepare the jet for the mission and
set the rest of the avionics up.

Sweep: The final sweep
1. The TEST panel is the first to be used in this sweep. Press and hold the
FIRE & OHEAT DETECT button and check the:
•
ENG FIRE warning light is on,
•
OVERHEAT caution light is on,
•
MASTER CAUTION light is on,
•
All lights go off when the button is released.
Press and hold the MAL & IND LTS button and check correct operation of the
Voice Message System (VMS) and that all lights are illuminated.
If you don’t
hear any sounds check the INTERCOM knob.
Flip the PROBE HEAT switch to the upper position and check that the
MASTER CAUTION light remains off. Move the switch to the lower TEST
position and check that PROBE HEAT flashes on the caution panel. Once you
are satisfied that the system works as advertised you can place the switch to
OFF again. We will come back later to test the EPU and the oxygen system.
The TEST panel is mostly eye candy and there are no consequences if the above checks are skipped.
2. Move one panel forward to test the FLCS. Before
doing so cycle and check the flight controls (stick and
rudder) to assist in warming up the hydraulic fluid and
removing air from the system. Check that all switches
are down prior to flip
the FLCS BIT switch. It’s a
magnetic switch that stays in place for the duration of the
bit test. The green RUN light comes on and the flight
controls are tested in sequence; progress can be
monitored by looking out of the cockpit at the flight
controls. Members of your flight are also able to see your
flight controls moving.
During the FLCS bit WARN will be displayed in the HUD
and the T/O LDG CONFIG warning light may also flash.
At the end of the self-test the switch will revert back to its
original position and the RUN light will go out.
In some cases the test might fail and the amber FAIL
light will then be illuminated. If that happens the only way to reset is to perform the BIT again. The
status of the FLCS bit is displayed in the FLCS MFD page.
The FLCS bit will initiate only if weight is on the main wheels and if groundspeed is less than 28 kts.
The next check is the Digital Backup operation, simply toggle the DIGITAL BACKUP switch up and
check that DBU on the right eyebrow is illuminated. Move the flight controls and check them visually
for correct operation. Once satisfied return the switch to the OFF position and check that the eyebrow
light goes off. Again, the HUD WARN message will be displayed during the DBU check and the FLCS
page on the MFD will display DBU.
Once all FLCS tests have been completed ensure all
switches are in the DOWN position on the FLT CONTROL
panel.
Both the FLCS bit & DBU are eye candy in BMS and have
no consequences if you skip them.
