Why: 14 CFR § 107.65 requires a remote pilot to have, within the previous 24 calendar months, passed an initial or recurrent knowledge test or completed recurrent training covering § 107.73 (or § 107.74 training for a qualifying part 61 certificate holder). AC 107-2A § 6.7.2 confirms the 24-calendar-month recurrent training cycle.
Part 107 has no recurrent flight-hour requirement; recency under § 107.65 is satisfied through knowledge testing or training, not logged flight time.
Remote pilots do not hold an FAA medical certificate under part 107, so there is nothing to renew; recency is purely a knowledge requirement.
