A320 brain teasers
Doing some revision of some A320 past papers and got stuck on a few questions (4). Would appreciate some opinions on these brain teasers!!
1) During taxi for take-off on snowy taxiways, you get the following ECAM warning: "ANTI-ICE CAPT TAT FAULT"
a) Check MEL and proceed for take-off under MEL guidance
b) Disregard warning as this is normal
c) Return to stand as Capt's TAT probe must be servicable
d) Disregard warning unless it is accomanied by failure warnings
B can be immedeatly disregarded, while since I do not have an MEL I tend to think C cannot be so cathegoric. That leaves A or D, though for D, Volume 3 simply states "crew awareness" for a TAT fault.
2)For RVSM operation with ADR 3 inoperative:
a) Request new clearance to avoid flight in RVSM airspace
b) For FL300/.78 maximum difference between altitude indication on PFDs should be up to 355ft
c) Record altitude indication on PFDs and standby altimeter for future use.
d) Check that PFD altimeter indication are within tolerance every 30 mins.
All I know on this one is that just 2 ADRs are needed for RVSM ops, thus making ADR 3 redundant. That rules out A but no clue about the rest, though I think C can also be ruled out.
3)APU Fire Extingusher Discharge light:
a)Illuminates amber when fire extingusher bottle has lost pressure
b) Does not illuminate when fire extinguisher bottle has lost pressure due to overpressure
(a) is definately right but (b) not sure about this, but sounds plausable if overpresure is by a fault (leak) in the squib, for example.
4) If before take-off the crew selects a FLEX TEMP that is less than the current TAT and the thrust lever is set to FLEX/MCT gate for take-off;
a) The Engines produce TOGA trust
b) The engines produce MCT thrust
c) The engines produce FLEX thrust
d) The take-off configuration warning sounds
I would think (a) TOGA; but actually I think you would get a value that would be the same as (equal to) TOGA, but stand to be corrected
Just checked again for any RTFQs!!!!.......Any ideas?
