Its Baaack! You know,"That Boeing Battery"

Its not what you think, and its its certainly not another battery melt down on the 787  as was the conditioned on an ANA's 787 that occurred last year. Instead its a no answer on causal battery effect for melt down. Japan, after much study, testing and theorizing cannot find the needle in the haystack. There have been changes in manufacturing standards which tighten the envelop of manufacturing defects of operational constraints, where both the battery maker and battery parameters funnel the parameters through a finer eye of that needle. It has wrapped in in metal and vented its gas in an appropriate manner. Using a just-in-case plan B, no harm no foul approach.

The needle has not been found, only new types of battery results and theories, which float the ethernet in abundance. Birds fly, but we don't know how, with 16th century sentiments remaining on the table. New batteries are being designed that can't, won't or would lose its its temper and melt down. Those new ones are years away, but possible as testing suggests. Boeing is stuck with the LIon on its needle head ready to swallow. Thank goodness for the "LIon steel cage", as is good as it is, just don't let it out of its cage.

Here is, as found below, what Japan says today. How perplexing the LIon is even when a Japanese firm makes the Boeing LIon.

Japan fails to find why ANA's Boeing 787 battery melted down



What LiftnDrag has learned since the first fire:
  • Many causal or a combination of conditions exists even though nothing is identified for certain
  • Many precautions are having a greatly improved effect on battery safety
  • Factory production updates on its LIon, gives assurances, and contributes towards reduction or elimination of meltdowns.
  • Boeing containment system works well in real time operation when it smoked.
  • Airline battery procedures for replacement and monitoring of "that battery" is keeping ahead of any problems.
 Bottom line, Boeing and partners have completely corralled the beast, but the beast is still standing, albeit, in a pen.

  • It is passenger safe in a worst case scenario, such as battery explosion, fire, and smoke. 
  • The airplane flies safely without its ground support battery. 
  • It has been made safe for the passengers during a catastrophic failure. 
  • The LIon can wait for its replacement.  
  • ANA has joined the line of people throwing its hands in the air over the issue.
Safety redundancy is a paramount safety process for airlines flying today. Discovered weaknesses in theory are back-up by other situational safety measures.

The LIon battery is in the same class found in all Airplane systems, where situational events are supported by additional flying options and employment of safety solutions or regimens. 

Example One: What if the power is lost on board ( not a battery issue)? It has several options to land, one is a Ram Air Turbine (AKA RAT). This was standard equipment even before the LIon battery existence.

Boeing or its partners will never stop in its pursuit of the Battery solutions. Industry is currently closing the LIon gap with new and more powerful batteries that won't heat, smoke or destabilize under operation.
