Do the Level I/II/III baggage scanners sometime indicate a false positive? That is, the baggage really does not contain contraband, but the scanners indicate they do?
Also, do the scanners sometimes indicate a false negative? That is, baggage contains contraband, but the scanners indicate the baggage is clear?
For instance, suspicious baggage caught by my Level I Scanner is sent to the Destroyer. If that’s a false positive, then it needs to be scanned by Level II and Level III scanners to clear it.
I get your logic but it still feels so wierd to me. It feels wrong to upgrade the system to filter out false positives. You upgrade your system to filter out “false falses” so to speak. You want to upgrade to specifik scanners so you can be sure that the genaral scanners dont miss explosives, drugs contraband etc…
EDIT: don’t know if i wrote it correct but point is that i want bagage thts scanned by general scanner to be scanned again to make sure that theres no explosives etc… I’m not scanning again to filter out bags that was incorrectly identified.
If I get you right, your method doesn’t make sense.
Why scan a bag again, if it’s already being scanned as ok? Then just skip the first scan and do the second (or third) accurate scan only, as the first scan is just a waste of time and money (you don’t need to buy and operate this scanner then, do you?).
The logic of my (and EG0611) method is, to do a (fast) scan of the bags in a tier one scanner, which isn’t that accurate, but very cautious causing false positives.
So that any suspicious bag gets a second scan. This scan may be slower (not part of the mechanic yet), but more accurate and mistakly false positives will be sorted out. (your PAX won’t be pleased, if you destroy their bag just because they take their vibrator with them. )
The same then for the more accurate but even slower tier three scanner line.
At the moment this isn’t needed, as there is no speed difference for each tier scanners. But as soon as there is, this method helps to avoid congestions.
Tier III has some false negatives, it “depends on operator skill”
Tier I has false negatives too
Tier II seems to be fine from my testing
EDIT: I meant that Tier I has false positives.
Ok, I should have asked.
By false negatives, you mean that the baggage has, say, drugs in it, but the operator determines that it has none.
Is that correct?
Ok, thank you. Now how I detirmined it.
I was watching the scanning system and I was ramdomly clicking on bags that got rejected by Tier I. A few bags had body parts in them, by kept getting rejected.
EDIT: And now i realize im an idiot
i meant false positives
sorry
