Ace Your 107

What are the maximum impact kinetic energy thresholds for Category 2 and Category 3 eligibility, respectively, under 14 CFR §§ 107.120(a)(1) and 107.130(a)(1)?

Why: 14 CFR § 107.120(a)(1) sets the Category 2 injury-severity-equivalent limit at 11 foot-pounds of impact kinetic energy; § 107.130(a)(1) sets the Category 3 limit at 25 foot-pounds.

  • This confuses the 0.55-pound Category 1 weight limit with a kinetic-energy figure, and understates Category 3's actual 25 foot-pound threshold.
  • This reverses the two thresholds — 25 foot-pounds is the higher Category 3 limit, not Category 2's; Category 2's limit is 11 foot-pounds.
