Wide-Body Trijet Airliner

FAA approach category D Typical Vref 140 to 165 kt 2 aircraft

Target for descent rate

60 to 120fpm

Full marks for descent rate up to 120 fpm; under 60 fpm the coach says the touchdown was softer than this aircraft is normally flown.

Scoring thresholds.

Roundout applies these 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 for each part; the composite formula is in the scoring methodology.

Descent rate at touchdown (fpm)The score at each point of the curve.

100≤ 120fpm

90≤ 173fpm

75≤ 253fpm

55≤ 360fpm

35≤ 467fpm

10≤ 600fpm

G-force at touchdown (g)The category's own curve.

100≤ 1.10g

90≤ 1.22g

75≤ 1.41g

55≤ 1.65g

35≤ 1.89g

10≤ 2.20g

Ideal touchdown zone: 300 to 700mpast the threshold
Tail-strike limit: 9°1 of its aircraft have their own
Approach-speed tolerance: ±7%of Vref, at least 10 kt

The 2 aircraft in it.

Every one of them is held to the target above. What sets them apart is their own Vref, quoted at the reference weight, usually the maximum landing weight; Roundout adjusts it to the weight you land at.
