The Jacobson Flare ®

Flight deckIn this age of technical precision, the manual landing flare manoeuvre has remained imprecise. Conventional flare techniques have involved an inconsistent, critical estimation of height above the landing surface and are subject to a number of variable factors, summarised as aircraft, pilot, and environmental. There has been no acceptable, quantifiable, universal landing technique in the history of aviation, or any recognition of the need for one.

This presentation discusses the development of a practical and very tolerant technique for establishing a consistent landing flare that does not rely on the pilot's perception of vertical height. It applies simple triangulation to provide a visual fix for commencement of the flare. The flare point is derived from a pre-determined longitudinal position on the runway centre-line, ultimately superimposed by the cockpit lower visual cut-off angle. No device or modification is required. Therefore no costs are incurred.

Major advantages over existing techniques are:

Ø      Landing an aeroplane may now be regarded as a skill that can be learned. Pilots are provided with a predictable and consistent visual eye path from final approach through to touch-down. Traditional training methods have assumed the manual landing to be non-quantifiable; this concept enables an original and precise interpretation for a manoeuvre historically regarded as an 'art'.

Ø      Most of the variables affecting perception and judgement may be discounted.

Ø      It simplifies elementary and advanced pilot training for student and instructor, reducing time and cost.

Ø      This technique is "pilot portable" and may be adapted to successive aircraft conversions.Click to enlarge

Ø      Experienced pilots can better maintain consistency of standard by utilising this "visual fix" to complement their highly developed levels of judgement, co-ordination and skill.

Ø      It minimises runway occupancy times.

Ø      It greatly enhances safety.
