I assume you guys use Foreflight for FAA pubs? What about flight manuals, TOs, etc? For non-FAA (AFMAN/AFI/etc) we use Goodreader.
Foreflight? Ha, that's way too useful for 121.
We use Jepp FD Pro for all our charts. Functionality has expanded since I started two years ago. We got own ship position on taxi, then approach, then on SIDs and stars. We now get weather in Jepp and even D-ATIS at appropriate airports.
For weather, we primarily use WSI, but Foreflight also serves as a legal source for weather and Notams.
It is useful to note that we can't connect our tablets to the in flight weather and we are specifically prohibited from using an ADS-B reciever. So the only way to get inflight weather is get Digital ATIS, use our onboard radar, or text the dispatcher.
We have another program called Comply365 for all our pubs. It keeps everything current and has a Read and Initial type functionality.
