Falcon 7X Main Ship Battery Longevity

October 2020

According to a Falcon Service Advisory FSA-00-10-009-R12-E on the Falcon 7X aircraft, the mainship batteries are one of the main drivers for cancelled or delayed flights. Due to the design of the Falcon 7X electrical system, the #1 battery is solely responsible for the APU start.

Recommendation

We recommend swapping the position of the #1 and #2 batteries during the 12M capacity maintenance event in order to optimize their longevity.
