Of course it’s only supposed to actually deploy with WOW. One wonders if and if so, how this was addressed in Boeing’s 787 electrical power systems safety analysis in terms of hazard/risk assessment and probability of failure
My outrage at TCMA Included my ignorance of this procedural decision....It also came on the heels of Boeing's reluctance to ground the 787 after (Emergency) Battery fires in 2012...mostly apologies to tdracer and moderators....
