OK the FAA has cleared Boeing for flight testing, my only problem is that
they are proposing a change of the cells position between each other in the batteries. This is to help in cooling between cells.
IMHO I don't think that is the answer.
The ability to see the charging rate of the battery, along with voltage and the heat of the battery during the process of ground operations is key to all their problems.
Once that has been discovered then the problem can be solved.
The electronics, coils, and cables during ground operation is the answer.
Soon rather than later this will be determined.
The FAA said that they needed to be 1000% certain(yes, thousand) before they would allow the plane to fly commercially again. If this temporary fix gets them to 1000%, why wouldn't it be the permanent fix, too much weight?
It will not be a permanent fix at 1000% percent.
Not until they know with absolute certanty what caused the batteries to overheat will we know the answer.
Untill then it's just a wait and see.
Don't believe what you read or hear from the media. Only from BA, NTSB and FAA
There has been only one flight allowed. The FAA has not cleared them (yet) to do any more tast flights.
The BA proposal for increased cell protection/distance is what the WSJ said is a possible interim step to get planes airborne while the NTSB continues to look for the root cause. I suspect the one flight is to gather data on the new design to give to the FAA/NTSB. Hopefully it leads to removing the flight ban and the root cause can be discovered.
Thousands of flights have taken place with the 787 without a problem prior to the fires and smoke on the two aircraft.
The test flight will prove nothing. It will be a normal flight without any problems.
UNLESS they see a battery problem prior to takeoff. Then we will see the problem.
If so, it is a charging problem.
We will be waiting to see the results.
IMHO I think it is a charging problem.
