How to connect a GPU ?
Position GPU unit in front of aircraft nose with brakes on.
Ensure cabling does not interfere with PAX embarking or disembarking the aircraft.
Plug the 28v cable into the GPU access port
Activate the applicable switch to provide power to the aircraft.
What sort of power does a rectifier convert and provide to the Aircraft ?
Converts 415V AC at 3 phase to 28.5V DC to supply the A/C
Can we operate the diesel powered Generators used for GPUs ?
No.
How do we know the Rectifier is QANTAS owned ?
It will have a QANTAS OWNED sticker on it
Rectifier serviceability ?
No U/S tag on the rectifier
No obvious signs of damage, cuts in the wires, evidence of arching.
Excesssive kinks or bends in the wire, the plugs are fitted correctly with no angular bend forces on them.
Rectifier precautions ?
Do not move the rectifier
Don’t use if U/S
Don’t turn on or off during refuelling
Don’t disconnect or connect leads unless the unit is switched off
Don’t adjust the voltage or any settings
If severe weather then switch it off, to avoid damage
Beware of any trip hazards from the unit.
Operating instructions with rectifier units ?
Ensure the unit is in the correct position.
Ensure the unit and power supply are both switched off.
Plug the cable into the power supply socket on the aircraft.
Turn the power supply on
Turn the rectifier switch on
Ensure green DC ON switch light illuminates.
To switch off, turn the rectifier unit off, turn the supply power off, unplug

Documents to be carried whilst at work ?
AUS license, Medical, cyclic/ line check card and passport if international
Can we refuel with pax onboard, if so how ?
Yes as long as it’s not over wing refuelling
Must stop if fuel vapour is detected inside the cabin
Flight crew to notify the cabin crew that refuelling will take place
Fasten belts sign off, no smoking sign on, emergency lights ARMED
Passengers are to be advised that refuelling is taking place
Exits are clear, doors open and Evacuation can immediate
Can we refuel with the APU running ?
Yes need to be pressure refuelling
APU is not to be turned off or on when refuelling
Left main tank has enough fuel for APU
Fuel truck parked 9.2 m away
Fuel spillage refuelling is to be stopped immediately
At ports where they are not accostumed to refuelling they need to be noticed the APU Will be operating
What must we check when refuelling is complete ?
Refuel access panel closed and refuelling on light is out
If you are starting the engines during the pushback when do you do the start checks ?
After all doors are closed and start/pushback clearance is received.
Main and Aux battery loads between engine starts ?
0.4
What do we Reject for in the high speed regime ?
Master warning, engine failure/fire, directional control issues, anything that the captains deems would make the aircraft not fly able.
What’s CAMO stand for ?
Continuing airworthiness maintenance organisation.
What’s AMO stand for ?
Approved maintenance organisation
What’s MOCO stand for ?
Movement Control
Enroute thunderstorms avoided by how far ?
20nm
How long to leave the aircraft before doing a magnastick check ?
5 mins
Basic airport requirements for LAHSO ?
ATC, Airport runway and taxiway signage refer to AIP.
Two modes of LAHSO ?
Passive or active, active is aircraft landing and holding short. Passive is the aircraft which had unrestricted use of the RWY.
If you can’t participate in LAHSO ops what must you do ?
Notify ATC as soon as practical.
Pilot approved maintenance tasks are outlined where ?
In the FDEM.
How many re tests of the 24 hr system checks can we do ?
1 re test
What’s CAO 20.7.1B ?
Aeroplane weight and performance limitations specially above 5700kg
What’s a contaminated runway ?
Runway that has more than 25% of the runway surface area required covered in Water or slush more than 3mm deep. Lose snow more than 20mm deep. Or compacted snow or ice.
What’s the take off distance a available?
The length of the takeoff run available and if Clearway is provided the length of the clearway for climb to 35ft
Four declared distances for all runways ?
TORA, TODA, ASDA, LDA
What’s ASDA ?
Consist of TORA plus stopway suitable for use during a rejected takeoff
When would we use a STODA ?
To reduce the climb gradient required after takeoff. You sacrifice Takeoff distance to reduce climb gradient.
All takeoff gradients are based on obstacles within a pre defined survey area which is usually ?
180m wide at the end of the clearway.
15km out at an angle of 12.5% until 1800m at the end of the surveyed area
Obstacle clearance must be established for all obstacles within ?
The take off area. 150m at the end of the clearway. Out at 12.5% until reaching a safe altitude.
Limitations with published gradients ?
And what’s the solution?
Obstacles outside the survey area have not been considered and they may need to be. Engine failure procedures that incorporate turns to avoid climbing over big obstacles.
Maximum brake release weight is defined by the most limiting requirement of ?
Takeoff distance Takeoff run Accelerated stop distance Climb gradient OEI obstacle clearance OEI
How’s your takeoff distance calculated ?
Start to 35ft @V2 greater distance of AEO +15% or OEI at V1
What’s the Takeoff run ?
Ground roll plus half the distance to 35ft. Greater distance of AEO +15% or OEI at V1
What’s the ASD ?
Start to Accelerate to V1 and then come to a complete stop. AEO or OEI action at V1
What’s your minimum V1 value based on ?
VMCG which is the minimum for maintaining directional control on the ground.
Climb gradient requirements 4 segments ?
1st segment 35ft to gear fully retracted = positive rate.
2nd : Gear fully retracted to minimum 400ft QLINK 1000ft = 2.4%
3rd: Acceleration to final takeoff climb speed= 1.2% Available.
