So why did BA change from empower to 115v/60Hz?
One of the more dubious changes I have seen is the new BA club world at-seat power supply which is now 115v at the floor rather than the 15v empower system.
Despite the fact that inevitably it will have trip protection, how can it be safer?
I used the system recently and I continually got 'belts' from touching the metal parts of the new seat. In the dark, upstairs on a 744, I rested my right hand on the metal of the table, and my left hand brushed the side of my laptop, one of these 'wee blue sparks" jumped from my hand to the unoccupied USB port on the machine, which promptly said "there has been a power surge and this point will be shut down as a precaution".
So I am not convinced its a positive development. Is this a grounding issue?
