This is critical, to assure runway threshold clearance by the landing gear, yet still maximise the landing distance available. This line is generally never defined and these depictions never explain, or nominate the development of an aim point, let alone offering any method to calculate an appropriate aim point for every airplane type (size). Let’s take a simple look at the 5 simple pillars that underpin the Jacobson Flare: Where to aim How to aim When to flare How much to flare and How fast to flare? For these are the keys to understanding the vast differences from the conventional, non-standardised methods, that derive from the pioneering aviators of World War One, passed down without serious challenge or development, for over 100 years.Ĭonventionally drawn, a final approach elevation profile diagram, published in text books and manuals, then depicted on whiteboards and flight training software, will usually display just one sloping line to depict the approach path angle. The fully comprehensive and illuminative description of The Jacobson Flare is contained and presented in The Jacobson Flare App (see further details, below). It is not intended to to provide flight instruction advice to individual readers. The following material is descriptive, only, to provide a simple discussion to offer an initial understanding of the principles that underpin The Jacobson Flare. So far, so good, you say, but you are well entitled to ask: “ OK, but what’s so different from what I’ve just been taught?” … or … “Why would I need it? I’ve been landing airplanes for 20/30/40 years?” These are fair questions but, in a truly honest moment: Do you fully understand, can you explain, can you determine how and why you can perform a ‘greaser’ of a landing on most occasions and then a ‘howler’, the very next time? We can blame a gust or some inattention or distraction but are these reasons, or just excuses? The improvement in confidence, competence and progress of pilots – at all levels – is not only breathtaking: It’s consistent and it’s measurable.’ The flare is initiated from a visual fix, derived from the cockpit lower visual cut-off angle ( the lowest angle visible ‘over the nose’) and the flight path angle, offering a precise and visible model for both student and instructor. ‘Accounting for all – even self-compensating for many – of the variable parameters that have distracted the attention of pilots away from the 5 essential elements of all landings: Where to aim How to aim When to flare How much to flare and How fast to flare?, the Jacobson Flare explains landings as never before.įlown initially at a constant angle, the eye path translates to the classic exponential flare curve that generations of pilots have attempted to execute by judgment alone. Since the development of The Jacobson Flare from 1985, pilots are presented with a fully-defined visual eye path, determined by the airplane type – making the landing safe, sure, simple and universal. This framework confirms to the pilot exactly what is happening at every stage, dispelling the myths that ‘ trial and error‘, ‘ developing a mental picture‘ and ‘ feel‘ are the only ways to master the landing.ģ. The Jacobson Flare uses a visual, logical, geometric framework to guide the pilot from final approach to a perfect touchdown – in the right place.Ģ.
