sb_sfo:
My feeling is that this may be a longer-term action.
A lot of issues to consider:
1) What caused BOS incident? Suppose was the charger and battery associated circuitry (best case scenario)
2) What caused TAK incident? Suppose was the charger and battery associated circuitry (best case scenario)
3) What is wrong with these parts? The Engineering team probably yet know. (best case scenario)
4) What if nothing with these parts? In this case the batteries could be the factor. What to do? (IMO this is the worst case scenario)
5) Options? a) The charger and circuitry for NiCd batteries are
DIFFERENT
b) The battery (for the same AH rating is bigger and heavier) has not a direct replacement. So,
6) FAA review
7) Pressure to return ops. (from many players)
8) Risks of further damage to images in a precipitated decision before safety is guaranteed.
To be continued.
How long? In the best case scenario, week(s). In the worst case, month(s).
(This is a risky comment) Your feeling is the same i have. BIG ISSUE.
PS
Just an analogy: If it was needed to replace the batteries of my mobiles and laptops the new volume and new weight would be at least twice.
