STEP 0: PREP AIRCRAFT
0.1
Connect adapters and hoses to the aircraft, tape-up all unused ports on the aircraft.
0.2
Leave hose ends near the 6600 but DO NOT connect to 6600 yet.
STEP 1: SELF TEST
1.1 Open at least one each of Pt, Ps1 and Ps2 ports on 6600 to ambient. Close all Vent valves.
1.2 Turn ON 6600 and run SELF TEST (NEXT SCREEN twice; GO).
STEP 2: SET GROUND
2.1
With ports still open SET GROUND (F-7 ; GO)
STEP 3: LOW LEVEL LEAK CHECK
3.1
Connect hoses from aircraft to 6600. Close all unused ports on the 6600.
3.2
GO TO GROUND (F-8 ; GO)
3.3
Pitot Leak check:
a. Airspeed Target = 200 knots; GO
b. Setup Pt Mode = Leak ("L" flashing) wait for Pt to stabilize at 200 knots; GO
c. If Pt cannot achieve 200 knots or if Pt Leak exceeds 50 kts/min. (warning message ) then GO TO
GROUND, Go to MEASURE on Pt, Ps1 and Ps2, then find the leak. Go back to Step 3.2
d. If Pt leaks down to below 100 knots and leak has not yet been found then CANCEL out of Leak Screen,
allow Pt to "recharge" to 200 knots, then change Pt back into Leak Mode and continue searching for the
leak.
e. When Pitot is Leak tight, CANCEL out of Leak Screen and proceed to step 3.4
3.4
Ps1 Leak check:
a. Pt=200 knots; Ps1=Ps2 = 3000 feet above Ground; GO
b. Setup Ps1 Mode = Leak ("L" flashing) wait for Ps1 to stabilize at target; GO.
c. If Ps1 cannot achieve target or if Ps1 Leak exceeds 2000 ft/min. ( warning message) then GO TO
GROUND, Go to MEASURE on Pt, Ps1 and Ps2, then find the leak. GO TO GROUND, then go back
to Step 3.4
d. If Ps1 leaks down more than 1000 feet and leak has not yet been found then CANCEL out of Leak
Screen, allow Ps1 to "recharge" to target, then change Ps1 back into Leak Mode and continue
searching for the leak.
e. When Ps1 is Leak tight, CANCEL out of Leak Screen and proceed to step 3.5.
3.5
Ps2 Leak check :
a. Only if the Ps2 output is connected to the aircraft, repeat 3.4 for the Ps2 output leak check. Once Ps2 is
leak tight, proceed to step 4.
STEP 4: CHECKOUT AIRCRAFT INSTRUMENTS
4.1 Run Profile (F -4) or execute your Test Procedure to checkout cockpit instruments.
4.2 GO TO GROUND at the end of Profile or Test Procedure.
4.3 Turn off 6600, then disconnect hoses.
