There are some very stupid comments on this thread ( eh, unhelpful stacker
), why erode the flight safty barriers we have built up over the years?
We always strive to do the job 100% correctly,I would hope everyone in every trade does, and stupid comments such as "read the label then" & "Stackers don't play a major role in flight safty" show a basic lack of understanding of human factors and flight in general........ as someone said on the previous page, aircraft flightdecks have taken years and years to evolve, hence why emergancy systems are all black and yellow striped, important switches are in a red gate, flap systems have guards, undercarridge systems have lights, warning horns and controls shaped like wheels in a lot of aircraft. It has been evolved over years of painful lessons learnt, crew landed with no gear down, incorrect engine shut down, etc etc etc. Everything is made to make decisions and actions easier to take in times of very stessful/ high workload situations..
The basic fact is that we always find better ways to screw up, make something idiot proof and all you get is a better class of idiot. We all make mistakes, thats why aircraft have redundant systems, ejector seats, and all manor of other equiptment that is used in an emergency... cars have seatbelts and airbags......No one plans an accident do they?? The whole issue of the round can debate is that if all the normal systems fail, the safty net is there as a last chance to prevent cross contamination....
Imangine an engine and prop change On the C-130K. After the Cx, you need to refil the engine oil and the prop oil. The engine takes OX27, and the prop takes OM15, it used to be easy to see the difference in the oil cans just by looking at them, and 99.9% it is nigh on impossible to make a mistake due to reading the label, shape of can etc. Now imagine at dark O'clock on your 10th or 11th nightshift in a row ( not unheard of in theatre), in crap weather, maybe handing the job over to someone else, the oil cans get mixed up due to someone moving staging or whatever reason, and seeing the sqaure can of OX27, in a rush, under pressure, and probably complacent ( happens to everyone) due to having done the job 1000's of times before, you grab the can of oil (which happens to be the new square shape OM15) and start to put it in the engine. As its dark, wet, etc etc, you don't notice the colour until it is too late..... Could have easily been avoided in one simple solution, a different shape can...
Same as the old coloured 731 system, RED= U/S Green= S at a glance, I wager many items have been put back into stock U/S, or even fitted to A/C due to the removal of the simple colour code system
Do we not learn our lessons? There is an old saying that there are no new accidents, just new victims
