3. Move down to the MANUAL TRIM panel. A good habit is to always check that all needles are
centred, especially if you have a cockpit where knobs might not be so!
Place the TRIM/AP DISC switch in DISC and ensure that stick trim actions do not induce flight control
movement or needle deviation. Return the switch to NORM and apply stick trim to check needle
deviation and re-centre.
Failure to set the trims properly may induce problems during or immediately after the take-off
roll.
Those checks may appear like eye candy but as asymmetric drag is implemented in BMS ensuring
proper trim settings before take-off is strongly advised
!
4. If your mission could include air-to-air refuelling you
need to test the AR system. On the FUEL panel open
the AR door by flipping the AIR REFUEL switch to
OPEN and check the right indexer for a blue RDY light.
Hit the stick DISC button and RDY is replaced by an
amber DISC indication. After three seconds DISC goes
out and the blue RDY light returns. Move the AR switch
to CLOSE and the blue RDY light goes out.
BMS rarely develops a fault into the AR system so this check could be categorised as unnecessary.
5. The next item to check is the EPU but for the test to be valid we need to ask the
crew chief to first remove the EPU pin. This is done after engine start through the
ATC menu (Ground page). Please note you must be on the ground ATC frequency.
Once the crew chief has removed the EPU pin (preventing the EPU from actually
starting during your normal engine start sequence) the status message in the top
right corner of your screen will disappear.
Once the EPU pin is removed, move to the EPU panel and cycle the EPU to OFF
and back to NORM. With the mouse make sure you use a left-click to move it from
NORM to OFF; a right-click would engage the EPU which should be avoided on the
ground. The real reason is of no significance to us; hydrazine is toxic to your ground
crew
but we don’t have them in Falcon.
Check first that both the EPU GEN and EPU PMG lights are OFF on the ELEC panel.
Testing the EPU is done with the EPU/GEN switch on the TEST panel. Engine RPM
needs to be around 80% and the
parking brake can’t be engaged so make sure your
aircraft is still on chocks and back them up with toe brakes. Move the throttle to 80%
RPM, toggle and hold the EPU/GEN switch on the test panel and check lights:
•
EPU AIR light ON (EPU panel),
•
EPU GEN and EPU PMG lights OFF (ELEC panel),
•
FLCS PWR 4 lights ON (TEST panel),
•
EPU RUN light (EPU panel) comes on after five second
You can then release the test switch and return the throttle to IDLE.
If the green run light fails to come on reinitiate the test with a slightly higher
throttle setting.
This check can be omitted as, with the EPU switch in the NORM position, the
system will run automatically whenever needed.
6. Check the ECM panel and toggle the top left switch to OPR. This is the only
switch implemented on the ECM panel. While you are there check the AUDIO
panels one last time for correct volumes on COMM 1, COMM 2 and
INTERCOM. TACAN volume is not implemented and we set the ILS volume
earlier. No further action should be required as you set COMM 1 and 2,
THREAT and MSL tone volume knobs earlier.
