AIRBUS TECH
HOW LONG MUST THE TAKEOVER PUSHBUTTON BE PRESSED AND MAINTAINED TO DEACTIVATE THE OFFSIDE SIDESTICK?
40 SECONDS
Starting the APU on batteries only is limited to what altitude?
25,000ft
What pressure does the RAT operate at
2500PSI*
Verification REQ
What do the leak measuring valves do on the overhead maintenance panel?
Shuts off the flight controls
Verification REQ
Where does the hyd reservoirs get bleed air pressure from
Usually engine 1 or the cross bleed duct if number one pressure is too low
Verification REQ
What are the triangles on the CEO hyd SD page at the top?
System users and become amber when pressure below 1450psi
Verification REQ
What system uses hot air to heat?
3 outboard slats (3-4-5) and engine inlet
Verification REQ
What systems are electrically heated?
Cockpit windows, waste water drains, and pitot static sensors
Verification REQ
When are the TAT probes heated?
Once in the air. All other probes are heated after first engine start.
Verification REQ
What is the fuel feed sequence for the A320 during takeoff?
Centre tank pumps first until slats, then wing tanks feed engines during takeoff, 500kg of wing fuel used then centre tank takes over, centre tank empties then wing tanks empty to 750kg, then outer transfer opens.
VERIFICATION REQ
What is the operating pressure of centre tanks compared to wing tanks?
Centre tanks operate at 30 psi, opposed to wing tanks at 25 psi. This ensures centre tank fuel takes priority.
VERIFICATION REQ
When do jet pumps start operating in relation to wing tank fuel usage?
Jet pumps start once 250kg has been used from the wing tanks, then they top up the wing tanks until they are full.
VERIFICATION REQ
When does the ACT (Automatic Control Transfer) start and stop?
ACT starts 30 minutes after landing gear is up, when centre tank is below 5000kg, and stops when at 5750kg.
VERIFICATION REQ
What is the minimum fuel level for gravity feeding the centre tank?
Aircraft with jet pumps can gravity feed the centre tank down to 2T.
VERIFICATION REQ
When will G load show on the lower SD?
Above 1.4 and below 0.7 (2 seconds)
VERIFICATION REQ
When will LDG memo reset?
Above 2200RA, or won’t come up until 800RA
VERIFICATION REQ
How long after start will the Ecam memo show up?
2 minutes
VERIFICATION REQ
Types of failures?
Independent primary and secondary
VERIFICATION REQ
Side slip indicator full lock indicates what lateral G?
0.3
VERIFICATION REQ
Blue beta target, flap 1-3?
80% or 1.25 EPR (35% or 0.25 EPR)
VERIFICATION REQ
