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 |
|---|---|
| ≤ 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 |
| ≤ 1.27 g | 90 |
| ≤ 1.52 g | 75 |
| ≤ 1.85 g | 55 |
| ≤ 2.18 g | 35 |
| ≤ 2.60 g | 10 |
Other thresholds
- Ideal touchdown zone
- 400–800 m
- Tail-strike limit
- 11°
- Approach-speed tolerance
- ±4% 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.
| Aircraft | Vref |
|---|---|
| BAE Concorde | 163 kt |
| Bell X-1A | 160 kt |
| Boom XB-1 | 170 kt |
| General Dynamics F-111 Aardvark | 148 kt |
| Lockheed A-12 Archangel | 175 kt |
| Lockheed F-104 Starfighter | 175 kt |
| MiG MiG-25 Foxbat | 185 kt |
| Northrop YF-23 Black Widow II | 155 kt |
