We were on the JHAWK Arrival and had the flight plan and the arrival program in our FMS. I had the arrival displayed on my iPad and the other pilot had the ILS displayed on his iPad. As we approached the NOAHS Intersection; my iPad battery went dead. By the time the other pilot switched his iPad to the arrival; our FMS started turning to the airport rather than us switching to heading mode and flying a heading of 010. Approach noticed the turn in progress and gave a correctional turn and the flight continued with vectors to a visual approached. While the information that can be used on an iPad reduces the paperwork and weight carried; the time of battery life is not good on long trips so we will charge up the battery on our iPad's en route.
We were on JHAWK Arrival and had the flight plan arrival in our FMS. The pilot not flying had arrival on his iPad and the pilot flying had the approach on his iPad. As we approached NOAHS Intersection the pilot not flying iPad battery died and by the time the pilot flying was able to switch from the approach to the arrival page the FMS turned the plane toward MCI instead of the heading of 010. Approached noticed our errant turn and told us to turn 010. We now have chargers in the cockpit to ensure battery performance of both iPad's.
CE560 flight crew reports an iPad battery failure at an inopertune time during the JHAWK arrival to MKC; resulting in a track deviation after NOAHS.
