STANDBY ALTERNATORS

I just finished reading the September 2022 issue of Aviation Consumer with the standby alternators article, and wanted your readers to know of another offering that wasn’t mentioned in the article. Kelly Aerospace has the STC for Cessna 182S, 182T and T182T aircraft that adds a secondary alternator via a bracket and pulley installation to provide a fully redundant backup electrical system. 

I had this system added to my 182S in 2017 and it continues to perform flawlessly to this day. The advantage of the Kelly system is that the backup alternator they use is a 95-amp model, which is actually more capable than the stock 60-amp primary alternator. This means no load shedding is necessary when using the backup alternator. The installation was straightforward and the cost reasonable (under $6000 in 2017). I flew the airplane to Lake County Executive Airport in Ohio to have it installed by Kelly Aerospace, but they also ship out the kits for your local A&P to install it.
