kontraktor
haha....
ambo ni tak sampai tahap kontraktor...juz kuli sahaja...
ambo hanya pekerja biasa....daripada bidang aerospace....berjinak2 bidang civil...
bekerja dengan bapa saudara....membuat rumah size sederhana....memang memenatkan...bermula dari membuat tapak.....sehinggalah konkrit, seterusnya mengikat jongkong untuk dinding.....
dan seterusnya...sudah 2 minggu ambo bekerja...selepas abis final exam...balik kg...terus cari kerja....
kerja ni memang sangat penat....fullly use your body strength....contohnya gaul simen untuk konkrit....satu beg simen ( 50 kg ) + 5 kereta sorong batu pasir....then dalam mase satu hari gaul sampai 12 beg simen.....so...pasir tambah simen dalam 60 kereta sorong gaul simen + batu pasir + air....ni baru dalam masa 1 hari.....fuh!!!
lupe nak kira brape kg sume...tangan ni ase macam ringan je bila balik rumah....haha...
memang jd tough...kulit pun habis hangus duk tengah panas....
dah 3 kali col dari spirit aero systems....offer praktikal...kawan2 sume x nak pergi..lau yg nak pergi, mak ayah x bagi...huhu...dorang nak continue degree terus sume...
camne ni??

EYELASH
Reality, infinity
All the pieces here
Athletic shoes, Chocolate mousse
Cellular phone in his room
You will see one day, I'm here to stay
Hold your hand to me
We'll find a way
Lightning streaks, teary bliss
Slicking on the grease
With company you will see
What this all is meant to be
You will see one day, I'm here to stay
Hold your hand to me
We'll find a way
Close your eyes, snip your lashes
They fall within the ashes
The frosty old feeling, will melt oh so painlessly
Close your eyes, kill the darkness
The shears are in the closet

Steering Systems
Some a/c have free castering nose wheels; most have steerable.
Mechanical Steering Systems
Uses foot power to steer the aircraft – no assistance
Some types will disengage when the gear is retracted
Some types have an automatic centering device when weight is off the a/c
Tail Wheel
Conventional gear use the tail wheel to steer
May be a castering type with no steering capabilities (rudder steers)
May be lockable, for parking purposes
Power Steering Systems
Used where large amounts of force are required to steer
Controlled by pilots rudder pedals, OR
By a steering wheel, OR
By a combination of both
Most will require a towing bypass valve which allows
Ground crews to to the a/c without damaging the system
Retraction Systems
Purpose: reduce drag, or adapt a/c for landing on different surfaces
(consider retractable wheels on float systems)
Mechanical Systems
Crank mechanism, or uses a lever pulled by the pilot
This method may use a mechanical latch system to lock wheels “up”
No emergency backup available for this system
Electrical Retraction Systems
Uses a central motor and push-pull rods
Uses microswitches to detect when gear is down/locked, or up/locked
Hydraulic Retraction Systems
Most common system of retraction for most sizes of a/c
Used exclusively where landing gear is too large to be retracted by other methods
May use ED pumps, electric pumps, hand or wind-driven pumps
Emergency Landing Gear Systems
4 possible methods of dropping gear when hydraulics are lost:
air bottle “blows” the gear down
hand crank or ratched
separate hydraulic system (may be hand pump)
mechanical system which releases UP locks, and gear free-falls
Landing Gear Operation
4 main components:
shock strut
the wheel
the brake assembly
the trunnion and side/drag brace
scissors (torque links)
actuating cylinder
down & up locks
the bungee system
Using hydraulics, landing gear retraction requires greater energy than lowering
Gear rotates on the trunnion pin
Extending landing gear requires a release of the UP lock first, then
The gear can begin free falling, slowed by the snubber in the orifice check valve
Final few degrees of travel may require hydraulic pressure assistance
Bungee system is used for emergency operation:
Gear doors must be operated before extension & after retraction
Landing Gear Position Indicator Systems
Positive indication must be provided to the pilot that gear is down & locked
Safety system includes squat switches and other microswitches
Squat switches tell pilot when weight of a/c is on the wheels
Squate switches are electrically “open” when on the ground
Some a/c use warning horns: they sound when:
If gear is retracted, and throttle retarded to below cruise
Landing gear position indicators: show position of Landing gear
May use a system of different color indicator lights
ku harap
someone touch my heart .........
Merenungi hari-hari sepi
Aku tanpamu
Masih tanpamu
Bila esok hari datang lagi
Ku coba untuk hadapi semua ini
Meski tanpamu meski tanpamu
Bila aku dapat bintang yang berpijar
Mentari yang tenang bersamaku disini
Ku dapat tertawa menangis merenung
Di tempat ini aku bertahan
Suara dengarkanlah aku
Apa kabarnya pujaan hatiku
Aku di sini menunggunya
Masih berharap di dalam hatinya
Suara dengarkanlah aku
Apakah aku slalu dihatinya
Aku di sini menunggunya
Masih berharap di dalam hatinya
Kalau ku masih tetap disini
Ku lewati semua yang terjadi
Aku menunggumu Aku menunggu
Suara dengarkanlah aku
Apa kabarnya pujaan hatiku
Aku di sini menunggunya
Masih berharap di dalam hatinya
Suara dengarkanlah aku
Apakah aku ada dihatinya
Aku di sini menunggunya
Masih berharap di dalam hatinya
hijau daun - suara ku berharap -

LANDING GEAR SYSTEMS
Landing Gear Configurations
Two main types: Conventional, and Tricycle
Has nose wheel, which may be steerable
Main gear, on either side
Example: Cessna
Keeps aircraft level during take-off and landing
The most important advantage is its ease of ground handling.
Two main wheels
One tail dragger wheel
Reduced drag in the air
Reduced landing gear weight
Requires more skill in ground taxiing
The most important advantage is the ability to operate the aircraft over rough terrain.
Classification of Landing Gear
Main landing gear
Cushions landing impact
Heavily stressed area
Main Landing Gear consists of the main weight-bearing structure
Auxiliary landing gear includes tail wheels, skids, nose wheels, etc.
Nonabsorbing Landing Gear
Includes Rigid landing gear, Shock-cord landing gear, Spring landing gear
Rigid: helicopters, sailplanes. No flexing other than the structure.
Shock cord system: uses “Bungee” cords
Spring type uses spring steel (some Cessna’s)
Shock-Absorbing Landing Gear
Dissipates landing energies by forcing fluid through a restriction
This fluid generates heat, dissipated into the atmosphere
Two types: Spring Oleo, and Air-Oil Oleo
Spring Oleo is history by now
Air Oleos are all very similar: a needle valve restricts fluid flow
Air in the oleo holds the weight of the a/c on the ground
Air Oleos present in both retractable and fixed gears
Fixed Gear
Non retractable, usually bolted on to the structure
Often uses fairings or wheel pants
Cessna 152
Advantages:
Lighter weight
Less compex
Least costly
Retractable Gear
Designed to eliminate drag (the greatest advantage)
Can be either fully or partially retractable
Direction of retraction depends on airframe model
Methods of retraction: hydraulic, electric, mechanical, pneumatic
Critical area of aircraft maintenance for safety reasons
Hulls and Floats
Can be single float, or multiple
Definition may include floating hulls (ex. “Lake” aircraft)
Floating hulls may only require wing tip floats
Skis used for snow and ice (wood, metal, composites)
Skis may use shock cord to assist angle of ski attack
Skis are mounted on the same strut as tires
Landing Gear Components
Exact definitions of some components will vary
The Oleo strut is the widely used form of shock absorption on aircraft landing ge
ar.
Trunnions
Portion of the landing which attaches to the airframe
Supported at the ends by bearings
Landing gear traditionally extends from the center
Struts
Vertical member, contains the shock absorbing mechanism
Top of the strut mounts onto the trunnion
Strut forms the cylinder for the oleo (“outer” cylinder)
Piston is the moving portion (aka piston rod, tube or inner cylinder)
Oil is forced from the lower portion of the strut to the upper
Oil flow is restricted or varied according to a metering pin
Final weight of a/c rests on air in the top of the strut
Snubbers are used to prevent a sudden dropping of gear on takeoff
Metering pin controls the flow of fluid between the chambers.
The shock of landing is absorbed by the fluid being forced through a metered orifice. The metering pin gradually reduces the size of the orifice as the shock strut extends, which avoids a rapid extension after the initial shock of landing and related bounce.
Chevron seals are used in shock struts to prevent the oil from escaping
On nose wheel struts, a cam is built into the strut for the purpose of straightening
the nose wheel before retraction.
Filling a shock strut: “exercise” the strut in order to seat the seals, and remove air bubbles from the fluid.
Most shock strut oil levels are checked by releasing the air, bottoming the strut, and checking to see if the oil is at the level of the filler plug.
Information about shock struts: see:
Manufacturer’s maintenance manual
Information decal located on the strut
Mfr’s overhaul manual
Torque Links
Also called scissors assembly
Two A-frame members
Connects and aligns upper and lower cylinders
Connects the strut cylinder to the piston
Restricts extension of piston during retraction
Correctly aligns axle to the strut
Trucks
Located at the bottom of the strut piston
Axles are mounted on the truck
Trucks can tilt fore or aft to allow for a/c attitude changes
Drag Links
Stabilizes landing gear longitudiannly
May be hinged to allow retraction
Also called a drag strut
Side Brace Links
Stabilize gear laterally
May be hinged to allow retraction
Can be called a side strut
Overcenter Links (aka downlock mechanism)
Use to apply pressure to the center pivot joint in a drag or side brace link
Overcenter link is hydraulically retracted to allow gear retraction
Also called a downlock, and/or a jury strut
Swivel Glands
Flexible joint with internal passages
Route hydraulic fluid to the wheel brakes
Used where space limitation eliminate flex hoses
Shimmy Dampers
Hydraulic snubbing unit
Reduces tendency of nose wheels to oscillate
Piston type dampers
Piston and rod filled with hydraulic fluid
Piston has an orifice restricting speed of travel
Slow movement has no restriction
Large shimmy dampers incorporate temperature compensation
Vane type dampers
Employ stationary vanes and rotating vanes
Small passages restrict fluid movement
Central shaft rotation is restricted from moving quickly
Damper Inspections
Check for leakage & effectiveness of operation
Check mounting bolts and hardware
Most dampers are fairly reliable

aircraft fuel systems
An aircraft fuel system allows the crew to store, manage, and deliver fuel to the propulsion system of an aircraft. Fuel systems differ greatly due to different performance of the aircraft in which they are installed. A single engine piston aircraft will have a very simple fuel system.
The fuel is piped through fuel lines to a Fuel Control valve (Fuel selector). This valve serves several functions. The first one is to act as a fuel shutoff valve. This is required to provide the crew with a mean to prevent fuel to be sent to the engine in case of an engine fire. The second role is to allow the pilot to choose which tank feeds the engine. Many aircraft have the Left Tank, Right Tanks selection available to the pilot. Some Cessnas have only the “Both tanks” feeding position, and many have the “Both tanks” position in addition to the Left and right. The reason to have the Left and Right Tank option is to allow pilots to balance fuel load
Fuel System
Most modern aircraft are equipped with 2 or more fuel tanks (or cells). In high wing aircraft, the cells are housed in the wings. Since they are higher than the engine, the fuel flows down to the engine by the force of gravity.
On low wing aircraft fuel pumps are required. To initially get fuel to the engine for starting, an electrical “boost pump” is turned on to pump fuel to the engine. After the engine is started, a mechanical fuel pump driven by the engine feeds fuel to the engine. The electric boost pump can now be turned off.
Each fuel tank is equipped with a drain valve located at the lowest point in the tank. This drain allows the pilot during preflight walk-around to check for and drain off any water which may have accumulated in the fuel tank. There is usually another drain located at the lowest part of the fuel piping system. This valve must also be drained during pre-flight to eliminate any water which may have accumulated in the fuel lines. Associated with this drain is a fuel strainer which filters out foreign matter which may be in the fuel system.
A vent line allows air to enter the tank as fuel is used. During hot weather, fuel may expand and overflow through the vent when tanks are full.
A fuel selector valve located inside the cockpit allows the pilot to select which tank(s) are to be in use during flight. Most small aircraft operate with the selector set on Both, such that both the left and right fuel tanks are simultaneous feeding fuel to the engine. The pilot may set the selector on Left or Right tank as a means of equalizing the loading of the aircraft. Usually, the selector should be set to both for take-off and landing. Pilots of low wing aircraft should exercise caution in their fuel management if tank selection is other than both. Running a tank dry can cause the engine to quit and vapour lock to occur in the fuel lines. It may be impossible to restart the engine under these conditions.
There is a fuel gauge in the cockpit for each fuel tank. The lower 1/4 of the fuel gauge indication is marked with a red line as a caution to the pilot of a low fuel condition. The pilot should never rely on the fuel gauge as the sole measure of fuel remaining. The gauges on aircraft are subject to a variety of indicator errors. The pilot should therefore double check the fuel remaining based on the power setting of the engine in flight and time in flight.
Inside the cockpit a fuel mixture control and a fuel primer pump are located on the instrument panel. The mixture control is used to adjust the air/fuel mixture for the altitude being flown. It allows the pilot to adjust the fuel/air ratio entering the engine. As altitude is gained, the intake air becomes less dense. Less fuel must be fed through the carburettor to permit the fuel/air mixture to remain correct proportion. If leaning is not accomplished by the pilot, a rich mixture (too much fuel) results. This is not only wasteful of fuel, but can result in fouled spark plugs due to carbon and soot buildup on the spark plugs. A rough running engine results. An additional gauge called an Exhaust Gas Temperature Gauge can be installed in the aircraft as an aid in achieving the proper “leaning” of the engine.
The fuel primer is a plunger that can be used in cold weather to inject fuel directly into the carburettor as an assist in starting the engine in cold conditions.
Three different grades of fuel are used in reciprocating engine aircraft. These grades are designated by octane rating and are colour coded so the pilot can insure the proper grade of fuel is being pumped into the tanks.
