Rotorcraft (Helicopter)
FAA Approach Category A
40 aircraft
Scoring thresholds
FLARE applies these curves to every aircraft in this category, except where an aircraft carries its own G-force curve or tail-strike limit. Scores fall in a straight line between the points, from 0 to 100 per criterion; the composite formula is documented in the scoring methodology.
Vertical rate at touchdown
The rotorcraft curve, used instead of the fixed-wing descent-rate curve.
| fpm | Score |
|---|---|
| ≤ 100 fpm | 100 |
| ≤ 156 fpm | 90 |
| ≤ 239 fpm | 75 |
| ≤ 350 fpm | 55 |
| ≤ 461 fpm | 35 |
| ≤ 600 fpm | 10 |
G-force at touchdown
FLARE's general G-force curve, as this category has none of its own.
| Peak G | Score |
|---|---|
| ≤ 1.20 g | 100 |
| ≤ 1.40 g | 85 |
| ≤ 1.60 g | 65 |
| ≤ 2.00 g | 40 |
| ≤ 3.00 g | 10 |

Aircraft in this category
The 40 named aircraft FLARE recognizes in this category. ★ marks a hand-written landing guide. Vref is quoted at the aircraft's reference weight, usually its maximum landing weight, and FLARE adjusts it to the weight you land at.
