Glider / Sailplane
FAA Approach Category A
Typical Vref 45–55 kt
8 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.
Descent rate at touchdown
| fpm | Score |
|---|---|
| ≤ 100 fpm | 100 |
| ≤ 156 fpm | 90 |
| ≤ 239 fpm | 75 |
| ≤ 350 fpm | 55 |
| ≤ 461 fpm | 35 |
| ≤ 600 fpm | 10 |
G-force at touchdown
| Peak G | Score |
|---|---|
| ≤ 1.10 g | 100 |
| ≤ 1.18 g | 90 |
| ≤ 1.29 g | 75 |
| ≤ 1.45 g | 55 |
| ≤ 1.61 g | 35 |
| ≤ 1.80 g | 10 |
Other thresholds
- Ideal touchdown zone
- 50–200 m
- Tail-strike limit
- 14°
- Approach-speed tolerance
- ±10% of Vref, min 10 kt
Aircraft in this category
The 8 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.
