Just viewed the Boeing fix, very nice.
I know they are trying to cover all the bases and did a good job I think.
Two big points from my take on it.
1. Batts are not reqd during flight.
2. Safety box to be fitted anyways.
I think there are well covering the future when any batt fails that it's no problem at all. Apart from batt not avail for use.
I think they are doing a god job indeed.
I hope no 787 batt ever smokes again, but if they have a high failure rate, regulators will insist on more changes/ETOPS problems etc etc.
Batt or any problems with the 787 will make too much press over the next few years, that will have its own problems to be dealt with.
If they have any smoking batts in the box events, it will be interesting to see how the press is handled.
I guess they have learned a lot, toned down batts and made good changes to the overall system to keep it chilled and for it to be isolated when the computer says "not normal"
So two big items remain.
1. To get the batt fix certified.
2. Checking other systems on the 787 were certified using a correct process.
I wish the 787 good fortune...
