02 - Onboard to doors closed Flashcards
Describe procedures, limitations and techniques.
How do you check the battery charge?
[SOP]
Set them to off, then check at least 25V (which ensures a charge above 80%).
If not, charge the batteries (via APU or EXT PWR) for 1 h.
Put them back to on and check contactors closed on ELEC DC SD page.
What’s the procedure when there is only two EXT ground power connected?
[SOP]
If only two EXT PWRs are ON, and high electrical demand is expected (i.e., APU start or doors actuation), FC must turn off CAB FANS + COOLG.
When the APU is ON, load reduction is no longer necessary (set CAB FANS + COOLG back to ON).
During refueling, which doors are designated for a possible evacuation?
[OMA 8.2.1.3 Fueling Ops]
The following doors shall be designated for a possible EVAC (if not specified differently by the CAPT):
- 2 doors on main deck: ML1 & 2
- 1 door on upper deck: UL1, if not AVAIL: ML5
Can you describe some of the fueling precautions as per the GOM?
[GOM 17.3 Fueling OPS Precautions]
1) The aircraft parking brake must be set and/or the wheels must be chocked. The aircraft ground altitude must be within limits. Ensure there is sufficient chock clearance available to allow for wheels to move as aircraft may settle under large fuel uplifts.
2) Ground equipment must be positioned in such a manner as to allow for the aircraft to settle during refuelling operations. In particular, equipment must not be positioned under the wings.
3) Passenger embarkation or disembarkation during fuelling is to be performed under the supervision of a staff and the passengers are to be escorted to/from the aircraft and their route shall avoid the fuelling zone.
4) The use of radios, radio telephones, pagers and mobile phones within the fuelling zone must be restricted to operational necessity only. Photographic flash bulbs or electronic flash equipment must not be used within 3 metres of the fuelling equipment or any filling point on the aeroplane.
5) Fuelling operations must be suspended if severe electrical storms are close by. In the event where a lightning threat is eminent fuelling operations must be stopped.
6) Passenger baggage reclamation on the ramp shall be carried out away from the fuelling zone. Fuelling shall be seized if this requirement cannot be complied with.
7) The connection or disconnection of any aircraft electrical equipment, excluding aircraft powering devices is prohibited.
8) Electrical and internal combustion engines, other than those which are powering fuelling vehicles, must not be started in the vicinity of the aircraft or fuelling vehicles.
9) All fuelling vehicles should move forward into the fuelling position. Where/when visibility of the surrounding area is obstructed or if the vehicle has to be reversed a guide person must be used.
10) Warning flags/cones are deployed near the fuelling hose to prevent accidental damage.
11) Equipment performing aircraft servicing functions shall not be positioned within 3 m (10 ft) radium of aircraft fuel system vent openings.
12) The engines of unattended vehicles should be switched off. Vehicles must not be parked under the aircraft wingtip fuel vents.
13) GPUs must not be operated within 6 m (20 ft) radius from the aircraft fuelling vents.
14) The use of metal-wheeled equipment in close proximity to the aircraft is prohibited.
15) The aircraft must be properly bonded from the aircraft bonding stud to the fuelling source. If the bonding cable connecting the fuelling vehicle to the aircraft becomes disconnected during ground operations, the fuel operator must be immediately advised.
16) Personnel working within the fuelling zone, and those engaged in fuelling operations of the aeroplane, must not carry matches, lighters, hand warmers or similar potential forms of ignition, nor must they wear footwear with exposed iron or steel studs, nails or tips that could create a spark. Smoking and the use of naked lights is forbidden.
17) Fire extinguishing equipment on the fuel truck or bowser, and fuelling personnel trained in its use, must be readily available. Such equipment must be suitable for use for initial intervention in the event of a fuel fire.
18) Local airport safety regulations shall be followed in case of a lightning threat which may include stoppage of fuelling. Local regulations may require additional precautions, and these must also be observed. Advise the Pilot-in-Command and Purser of the additional precautions required.
19) Electrostatic charge may accumulate on the surface of the aircraft or fuelling vehicle. The aircraft and the fuelling vehicles must be electrically bonded together throughout the fuelling operation to ensure that no difference in potential exist between the units.
20) Static grounding of the aircraft by positive grounding means is not necessary when performing:
a) Pressure refuelling or pressure defueling.
b) When the airplane is parked or is being serviced during turnaround operation.
21) Static grounding of the aircraft by positive grounding means is recommended when performing over wing refuelling or other fuel related activities.
22) Electrical bonding between the aircraft and fuelling vehicle is required in all cases.
23) Electrostatic charge may also build up in the fuel during fuelling and if the charge is of sufficient potential, can cause sparking within the aircraft tank. The use of a static dissipater additive in the fuel can contribute materially to reducing the risk involved. A reduction in flow rate may be necessary if a static dissipater is not in the fuel.
24) Strong winds can also cause a build-up of static electricity. Large charges of static electricity can develop on support equipment while parked.
25) On some aircraft, changing or removing the electrical power source or electrical power transients, during the fuelling operation may close the aircraft fuelling valves, which can result in damage to the fuelling equipment.
26) Aircraft weather radar must not be operated. Aircraft HF radio transmissions must not be made. Aircraft strobe lights must not be switched on.
27) Whenever the flight deck crew are present (e.g. during a transit stop), their clearance must be obtained before fuelling operations commence.
28) The fuel dump system must not be activated
What must be done in case of fuel spillage?
[GOM 17.6 Fuel Spillage]
In the event of a fuel spillage, STOP the fuelling operations, advise the Captain or appropriate Authority and the Emergency services and follow the actions below:
1) The Airport Fire Department shall be summoned immediately as directed by Pilot-in-Command or appropriate Authority, evacuate all persons from the immediate area.
2) Mobilise firefighting equipment as standby protection until the arrival of the airport emergency services.
3) Control the movement of unauthorised personnel or equipment into the area.
4) All electrical equipment must be switched off immediately when fuel spillage is observed.
5) Mobile equipment, motor vehicles and aircraft located within 75 metres (250 feet) of a fuel spill, whose engines are operating, shall be driven/pushed back out of the danger zone if conditions permit this to be done safely. Equipment to have engines shut down.
6) Mobile equipment and motor vehicles located within 75 metres (250 feet) of a fuel spill, whose engines are not operating, shall not be started and shall be abandoned by their operators. The mobile equipment and motor vehicles can be moved under the direction and protection of the Fire Department upon their arrival.
7) All personnel and mobile equipment/motor vehicles shall remain a minimum of 75 metres (250 feet) from the fuel spill until the area is declared safe for entry by the Fire Department.
8) Normal operation must not be resumed on the aircraft or any engines started before the person in charge of the emergency determines that it is safe to continue.
What are the safety precautions during fueling as per the OMA?
[8.2.1.2 Safety Prec. dur. Refuel]
a. ENG IGN shall be off,
b. WXR must not be on,
c. Strobe LT must not be on,
d. HF transmissions must not be made, and
e. Smoking and the use of naked lights is forbidden.
[8.2.1.3 Refuelling and Defuelling when Passengers Embarking, On Board or Disembarking]
The FC shall:
a. Establish COMMs with the Engineer by means that remain AVAIL during fueling,
b. If the presence of fuel vapors is detected /reported, OR any other hazard arises, fueling shall be stopped immediately.
What must be done before releasing the fuel bowser?
[OMA 8.2.1 Fuelling Procedures]
The Commander shall ensure that the ordered fuel has been correctly loaded and distributed prior to releasing the fuel bowser.
TOW has changed by more than 2t. What can you do?
[OMA 8.2.1.1 Ordering of Fuel]
The Commander may request an updated OFP for TOW changes of two tons or more.
What are the implications of refueling with JetA?
[8.2.1.7 Fuel Freezing Point]
The variation of the freezing point of a fuel mixture is not linear. Therefore, the only reliable way to obtain an accurate freeze point of a mixture of fuels is to make an actual freeze point measurement. When this is not possible, apply the following:
JetA1 uplift at DEP ≥ 90%: Fuel Freezing Point = -47°C
JetA1 uplift < 90%: Fuel Freezing Point = -40°C
What if the OIS version of the aircraft differs from the OFP one?
[SOP]
If the OIS version on board is equivalent or greater than the MIN valid version number supplied in the briefing package (OFP), the OIS Version is valid.
If it is lower than the MIN valid version number, then the crew must consider the OIS INOP, & consult MEL for guidance.
After requesting and inserting the CPNY FPLN into the FMS, you realize the D-ATIS page does not display the airport fields as per the FPLN. Would you apply any procedure?
[PRO/ABN/ABN-RESET/COM – ATC Reset] {up to MSN 260}
It is possible to perform an ATC reset, when the Airport fields of the D-ATIS/LIST page are not updated with the right ICAO code following the FMS city pair (FROM/TO) initialization.
How many CDL negligible items are necessary to cause a drag increment?
[PER/TOF/TOC/AFS - CDL (CONFIG Deviation List)]
The CDL items subpanel displays the missing structural parts that the flight crew selects (yellow if via OPS LIB, cyan if via TOPA).
The CDL items subpanel also displays the number of Negligible Items.
If the number of Negligible Items ≤ 3, then no penalty applies. If the number of Negligible Items > 4, then a drag increase for each Item is applied.
What’s the validity of the Daily check?
Can it be extended?
[OMA 8.1.11.2 Daily Maintenance Check Validity]
A380 = 48h (UNABLE to be extended)
An ACFT shall not be dispatched on a flight, if a Daily Maintenance Check would expire before the PLANNED arrival time at the next station.
When checking the TL, you realize the previous Capt did not release the airplane. What can you do?
[Tech Log front Page]
In the event of previous Capt not releasing the TL, or the Purser not releasing the CL, inform the CDM.
Crew observes a malfunction (no ECAM triggered). How to address the situation in regards of dispatching the airplane?
[MEL/GEN/HTU - HOW TO USE MEL ENTRIES SECTION]
The MEL Entries section contains two subsections:
- The ECAM alert section,
- The Crew Observation section.
When an ECAM alert reports a system failure or when there is a visible system malfunction (without any ECAM alert), the flight crew and the maintenance personnel should refer to this section as the main entry point of the MEL for dispatch purpose only.
