Qatar Airways_A320 Line Training Technical Questions - Rev.03
Hey guys,
My personal notes from my line training on A320, all the technical questions, answers and tech references up to date. Quite a few guys didn't make it on this fleet and I don't think they were bad pilots but rather unlucky.
Please feel free to implement the revision number in the title with your own questions and we will get something good.
Hope it helps,
TCAS max rang? Proximity, TA, RA? DSC-34-80-10
THRT, ALL, ABV, BLW? DSC-34-80-20
TCAS TA, PF: “TCAS, I have control”, follow TCAS even with climb orders at max ceiling FCTM SI-060

intruders
TCAS TA, maintain safe separation if contact is established OM Part A 8.3.6
If under TCAS RA manoeuvre, ATC request opposite action: “unable TCAS RA”
When clear of conflict: “returning to FL xx or ALT xx”, and then “clear of conflict (assigned
instruction / clearance) resumed”

Fuel feed system sequence:
_ First the ACT (fuel transfer to the centre tank) DSC-28-10-30 p10/12
_ Centre tanks, if the fuel used to cool down the IDG overfill the inner tanks (via the DSC-28-10-60
transfer valves of the outer tanks or the spill pipe), then the centre tank pumps are stopped
until 500kg have been used in the inner tanks… and so on until the centre tanks are empty
_ Inner tanks down to 750kg each
_ Outer tanks through the transfer valves via the inner tanks
_ The last 1500kgs are in the inner tanks
Position computation DSC-22-20-20-10
IRS Mix is a point computed from the three IRS (with less credit for the one which is
drifting or one IRS each if only two are serviceable).
The GPIRS is a mixture of each IRS position and one of the two GPS (based of priority and merit).
The vector between the GPIRS (or the radio position if the GPS mode was rejected by the FMS/
deselected by the pilots) and the IRS Mix is called the BIAS. It is permanently updated by each
FMGC (unless loss of GPIRS and radio then it remains constant) and computed from the IRS Mix
to get the FM position.
If the pilots update the FM position, they also update the BIAS calculated from the IRS Mix.

Daily check validity 36 hours, 48hours at out station OM Part A 8.1.11.1.4
Tech log #16
An Air Crew Notice (ACN) can be reissued not later than after 3 months
Example of flight duty limitation: OM Part A 7.3.7
A cabin crew is in Std by between 0600 and 1800, she is called out from std by at 1600 OM Part A 7.3.8
and report at 1700. She was acclimatised and will fly 2 sectors. OM Part A 7.5
What is the total duty period allowed?
Called after 6 hours, 11 hours of duty plus 12h15m allowed minus 5 hours of std by
exceeding 6 hours equals 19h15 (1 hour more than the pilots)
Exceedance of flight duty time or reduction of rest periods:
_ In flight relief OM Part A 7.4.1
_ Split duty time OM Part A 7.4.2
_ Commander’s discretion to extend/reduce OM Part A 7.4.4
OM Part A 7.4.5
