Keeping ATP valid
Hi all,
Been a while since I've been in the CFI world, so sorry about the basic question. I figured that there has to be some others on here who are in the same boat as I am, so here goes.
I worked for an airline until April 2015, I was there for 7 years, and decided that I wanted out of the lifestyle and switched careers. I have an ATP that I got while I was at the airline, which was previously a commercial single engine privileges. I now have type ratings in a CL-65 and ERJ-170 and 190. My last training event was in February of 2015 (a proficiency check at the airline). My ATP license says issued December of 2012.
My question is this: what do I need to do to keep this license valid? I am not flying much at all anymore, but would still like to keep it valid. Do I just need to complete a biennial flight review to ATP standards? If so, when does that need to be done by? Two years from the last training event, or two years from the date on my license?
Thanks for the help.
