FUELING PROCESS AND LOCKS INTRODUCTION

FUELLING ZONE

The fuelling Area is|Sector is|Region is an
area of 06 meters around the aircraft tank filling or venting points, the fuelling browser or hydrant and the hydrant pit used for refueling. The air flow points can be found|are situated at the wing as well as for aircraft with additional tail tanks - at the tip of the right - hand part of the horizontal backing.

Ground Servicing Equipment, not immediately required for aeroplane handling, shall not be positioned within the fuelling zone.

The use of mobile telephones is totally forbidden within the fuelling zone.

Fuelling/de-fuelling:

Fuelling/de-fuelling is considered to start out as soon as the filler lines are linked to the aircraft and pressurized.


Fuelling/defueling shall only be considered terminated after all filler hoses have been turned off from the aircraft. The cockpit crew shall be informed about the end of the fuelling/de-fuelling process. The cockpit crew shall, in turn, inform the cabin crew appropriately.
The Engineer in charge or flight crew, as appropriate, shall ensure adherence to the protection precautions by spot checks.

Safety safety measures|safeguard  during fuelling / Defuelling.
 
During Fuelling/Defuelling this basic safety precautions shall be adhered to:
-    Fuel hoses shall be positioned by the shortest way to the fuel inlets. An Sufficient| safety distance shall be kept from wheel-brakes (at least 1 meter) and from the APU-air-Inlet as applicable.
-   
-    Bonding cable connections from the fuelling pickup truck|vehicle to the airplane must be established to release| any static electricity before fuel hoses are linked.
-   
-    Ground servicing equipment, not immediately required for the handling of the flight, shall not be positioned within the fuelling Zone.
-   
-    Spilled gasoline shall be removed or dry out immediately in the occurrence of the open fumes/flames brigade before passengers are boarded.
-   
-    The control switch must be used during fuelling. If fuelling is performed by two persons, one person must be present at the switchboard of the fuel bowser or hydrant all the time.

-    In case of overwing fuelling/defueling, ground power devices|products as well as aircraft auxiliary power units shall be linked and began up before the beginning of fuelling/defueling and shall not be turned off or disconnected until fuelling/defueling is terminated. No electric powered switch on the aircraft or on the floor|surface power unit should be managed whilst over wing fuelling is in progress, apart from such switches necessary for fuel.

-    During pressure fuelling electrical and/or, electronic systems may be operated as far as required during pre-flight activities, except weather radar and HF |might not exactly be used.

-    During thunderstorm fuelling/defuelling is strictly forbidden.

-    Safety precautions during Fuelling with passengers.


-    The start of refueling must be coordinated with the commander to allow him to brief the  crew concerning safety rules, restrictions  polices and procedures. After refueling is completed, the leader must be informed as well.

-    If during fuelling, passenger remains on embarking or disembarking, it must be|should be ensured that the fuelling process is supervised by a competent,  certified and a skilled person. All necessary steps have to be matched with the commanders.

-    The fuelling process must be interrupted immediately if it is observed that any of the safety rules are not adhered to.

-    If during fuelling, the occurrence of fuel fumes is detected in the cabin, the flight deck and or station staff|employees|workers shall be informed immediately. The fuelling/defueling process and other activities using electric powered equipment, for example, cleaning, shall be stopped immediately.


SECURING OF LOAD:

Weight on board an airplane must be secured properly to withstand following different forces take-off and obtaining.You will find four forces:

FORWARDS|FRONT: Horizontal forces effective during landing and steep sides of decent.

BACKWARD: Side to side forces effective during take-off and steep angles of the climb.

SIDEWARD: Side to side forces effective during difficult|hard landing, turbulence and close turn.

UPWARD: Vertical causes|makes effective during landing and turbulence in flight.
Depending on the flight situations, these forces can be robust than the normal gravity force 1g.

                                              KINDS OF LOCKS (INTRODUCTION)


We will be discuss and possess the working of different kind of  lock| used to a different kind of ULD's (containers/pallets/cargo) in a safe and secure manner. staff is calling them.

Door sill restraints,  center guide, Container {middle|centre} lock, Side restraint,  Double lock, End stop, Restraint rail and so on|and so forth
Not necessarily, all will be present in one aircraft. Sometimes, some LOCKS might have missing in the hold and a proper procedure mention about the weight. The weight of such positions in which tthe place that  unserviceable or lacking would be limited.
 

                                                          END STOP
Last to loading, the serviceableness of the pallet and the pallet net should be checked. Pallets shall |just be built after dollies or other roller-equipped loading systems. Heavy loading tools and rollers shall not be applied |right to the pallet floor. If such tools are required, the pallet floor must be|should be protected by use of spreaders. Large, heavy and strongly packed items shall be located at the bottom and as near to the centre of the pallet as possible.
