To answer Duck,
We had to produce EFB policy & procedures manual for CASA acceptance and subsequently received a letter of approval.
The aircraft has an EO for the fitting of an Ipad on each side of the cockpit with a dual USB power port on each side of the cockpit.
Each Ipad is 4G and has software for flight planning, W&B, naips, etc. Crew can lodge and re-file flightplans on the go, can download latest WX & notam, more importantly email the digital copy of the W&B back to our ops desk before departure. Included is access to AOM, AFM, MEL etc.
This has allowed us to rid the aircraft of paper and is a god send. In addition to this we also carry an ipad mini in the cockpit that has all company documents and aircraft approvals digital, COA, COR, Insurances, everything including the EFB approval.
CASA have accepted that we can maintain document control in this manner and meet the requirements. We have yet to have a SAFA ramp check and I think this will be interesting as in some places outside of Oz authorities have requested "Certified Originals".
The challenge was dealing with an FOI who understood the concept, it really came down to a "chicken & egg" scenario, cant use the EFB until you have the approval, cant get the approval until everything is in place. Eventually we ran with paper and EFB for about 6 months and proved no issues until we ditched the paper jepps.
We hung onto paper enroutes for about another 3 months but they have gone too now. We have not had any overheating issues re sunlight at all.
