Hi All.
Thanks for the feedback.
EASA has moved from being restrictive to be more allowing in their wording regarding the use of EFB's, but still require EFB's to comply with ED-130 and other documents, especially if it involves T-PEDs (transmitting personal electronic devices, i.e. iPad with 4G simcard). ED-130 is somewhat of a nightmare to navigate and require specialized testing equipment, so based on that I consulted you brilliant lot, to see if somebody allready were using approved solutions.
Thank you for the discussions so far, I will post my findings and solution here, and I am still open for input...
