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 |
|---|---|
| ≤ 150 fpm | 100 |
| ≤ 200 fpm | 90 |
| ≤ 275 fpm | 75 |
| ≤ 375 fpm | 55 |
| ≤ 475 fpm | 35 |
| ≤ 600 fpm | 10 |
G-force at touchdown
| Peak G | Score |
|---|---|
| ≤ 1.10 g | 100 |
| ≤ 1.20 g | 90 |
| ≤ 1.35 g | 75 |
| ≤ 1.55 g | 55 |
| ≤ 1.75 g | 35 |
| ≤ 2.00 g | 10 |
Other thresholds
- Ideal touchdown zone
- 120–400 m
- Tail-strike limit
- 9°
- Approach-speed tolerance
- ±11% of Vref, min 10 kt
Aircraft in this category
The 13 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.

| Boeing B-17 Flying Fortress ★ | 96 kt |
| Boeing B-29 Superfortress | 110 kt |

| De Havilland Canada DHC-4 Caribou | 77 kt |
| De Havilland DH-98 Mosquito Mk IV | 109 kt |
| Douglas A-1 Skyraider | 90 kt |
