The Jacobson Flare Lite now a video on YouTube

For some time, we’ve been asked to produce a Jacobson Flare – Lite: a simplified version, free of diagrams and the geometry and trigonometry that underpins the Jacobson Flare. We understand that there are some who feel that they wouldn’t understand a formal approach and landing technique, even if based on some very basic mathematics.

A picture is always better than a thousand words, but a real picture is unassailable; and we have a real approach and landing video, viewed from the cockpit. The downloadable, no-frills PDF presentation from our website homepage presents the practical application of the Jacobson Flare at YPOK Porepunkah, a grass-surfaced country airstrip at the foot of Mount Buffalo, in NE Victoria, Australia, based on a video from the Jacobson Flare App. The example airplane is the C172 and the images are a carefully selected group of screenshots from the video to assist pilots to identify, illustrate, resolve and integrate the five key elements of the approach and landing, namely:

1. Where to aim;

2. How to aim;

3. When to flare;

4. How much to flare; and

5. How fast to flare.

Now, the Jacobson Flare Lite has been published as a video on YouTube.

Each step is explained as simply as possible, through some brief notes, appended below each image. We suggest that you run the video through first, without any interruption, as an overview, before reviewing each of the selected screen images, in detail.

While the concept of using individual pages allows reading in your own time, it is useful to re-run the video at any time, to visualise application of the notes in real-time; the more times, the better.

Note: Use the video controls to pause, if more time is required to view a slide.

Were you just taught to land? … or were you taught HOW to land?

Many of us are familiar with the adage that ‘it is more valuable to teach someone HOW to fish, than to simply buy them one’. 

There is quite a difference: One is momentary – the other is forever. Landing training is similar.

‘Just taught to land’

Historically, instruction in determining a suitable and consistent landing flare height for each airplane type has been more an art passed on to an apprentice than the formal teaching of a technical skill. Pilots then attempt to recognise and recycle that flare height, consistently, by familiarity and repetition.

The student is expected to remember and reproduce this flawed height estimation, often at another airfield where the visual cues are always different and are offered no alternative: Trial and error have been the arbiters in advancing the soundness of this developing judgement.

Unfortunately, even after the basic skills have been mastered, the same fundamental problem exists because every airplane type requires a different flare height. When needed most – effectively, all the time – an accurate and universal flare model had never been available. After being endorsed on a new airplane type, experienced pilots generally consolidate their assessment of flare-height *. Although subject to the same issues, they become comfortable with the ‘feel’ of their new airplane after some indeterminate time and land it as well as any flown previously – if inconsistently; clearly so, for this method has been accepted and practised for a very long time; in fact, since the end of World War One, in 1918.

(* Even the concept of a ‘flare height’ is flawed mathematically, for every error in judging/estimating/guessing this vertical height compounds by approximately twenty (20) times longitudinally, along the runway.)

It is what is meant, here, by being ‘just taught to land’ by imitating and replicating our instructors’ demonstrations. It is worth keeping in mind that that is how they were taught, too!

‘Being taught HOW to land’

The distinction is very simple: Were you ever encouraged to consider the following five questions and research their answers?

  1. Where to aim?  (your eyes at a nominated aim point on the runway, suitable for the aircraft type)
  2. How to aim?  (using the controls correctly to fly a consistent, stabilised approach path)
  3. When to flare?  (using a simple visual fix to locate an accurate flare point – rather than guessing an elusive and flawed* flare height)
  4. How much to flare?  (utilising a second aim point, together with:
  5. How fast to flare?  (a simple means of developing the perfect flare – an exponential curved eye- and flightpath that we have all been trying – with mixed results – to emulate through judgment, repetition and feel).

The simple explanations and solutions for these five questions – on HOW to apply this technique to ANY fixed-wing airplane on ANY airstrip or runway – and much more – are described in the comprehensive 345-page Jacobson Flare App.

You will then understand the difference between being taught to land and being taught HOW to land.

35th Anniversary of the First Publication of the Jacobson Flare

35th Anniversary of the First Publication of the Jacobson Flare

The original Paper, ‘Where to Flare‘, written and presented by Captain David M Jacobson for the 1987 Australian Aviation Symposium, Canberra ACT, Australia, developed to become The Jacobson Flare.

18-20 November 2022 marks the 35th anniversary of the publication of the original Paper.

 

 

 

 

 

 

An abridged version of this paper appeared shortly after, in the Australian Department of Transport’s Aviation Safety Digest No 134 Spring 1987 edition.

 

For over 100 years aviators have, for the most part, known WHAT we are trying to achieve when landing an aeroplane; it’s the HOW that has been so elusive.

My long-held view is that the visual approach and landing manoeuvre is the worst taught and most neglected topic in the entire flight training syllabus, both civil and military because, until 1987, there had never been a universal, quantifiable and consistently reliable approach and landing training technique. A loose collection of myths and misinformation, opinions and guesswork do not qualify.

37 years ago, I developed a solution. However, the industry is yet to realise that it has a problem. The pathetic fallback, ‘We’ve always done it, this way’, is just not good enough, anymore.

If you agree, contact me and let us start a conversation on how you can introduce the Jacobson Flare to your Flight School or College training syllabus.

Please visit www.jacobsonflare.com and its various tabs. I commend The Jacobson Flare LITE.pdf as the best introduction yet for those new to this subject.
Here is a response from a former RAAF Air Commodore. I look forward to yours.

The Jacobson Flare LITE - How to land a plane explained.

THE New and Free Jacobson Flare Lite

For some time, we’ve been asked to produce a NEW and FREE Jacobson Flare LITE: a simplified version, free of diagrams and the geometry and trigonometry that underpins the Jacobson Flare. We understand that there are some who feel that they wouldn’t understand a formal approach and landing technique, even though based on some very basic mathematics.

A picture is always better than a thousand words, but a real picture is unassailable. We have a real approach and landing video, viewed from the cockpit.

This downloadable, no-frills PDF presentation presents the practical application of the Jacobson Flare at YPOK Porepunkah, a grass-surfaced country airstrip at the foot of Mount Buffalo, in NE Victoria, Australia. It’s based on a video from the Jacobson Flare App.  The example airplane is the C172 and the images are a carefully selected group of screenshots from the video assist pilots to identify, illustrate, resolve and integrate the five key elements of the approach and landing, namely:

  1. Where to aim;
  2. How to aim;
  3. When to flare;
  4. How much to flare; and
  5. How fast to flare.

Each step is explained as simply as possible, through some brief notes, appended below each image. We suggest that you run the video through first, without any interruption, as an overview, before reviewing each of the selected screen images, in detail. While the concept of using individual pages allows reading in your own time, it is useful to re-run the video at any time, to visualise application of the notes in real-time. The more times, the better.

A fundamental aspect of the Jacobson Flare is the relationship between the pilot’s eye position in the cockpit and the position of the main landing gear of the airplane. While the subject airplane was a late model C172, the criteria used in this example at YPOK is equally applicable for a wide range of comparable 4-6 place single- and twin-engine light airplanes.

The notes that introduce the following presentation define three key locations on the airstrip for an initial aim point 1 at approximately 300ft/90m from the approach threshold; a longitudinal flare cut-off point (used to create a visual fix in place of a conventional guess of flare height), located at 200ft/60m (or 100ft/30m short of aim point 1); and an additional aim point 2, located at the upwind threshold. These have been pre-calculated for airplanes of the above description and, in this case, located by measurement. (The Jacobson Flare App content and on-board calculators cover and simplify this once-only step.)

An unsealed gravel runway would be equally adaptable to the Jacobson Flare, as there are always discernible contrasting marks suitable for selection as the Aim Point 1 and flare cut-off point, respectively. (While these distances may need to be estimated, the use of a longitudinal flare fix is 400-times more tolerant of error, compared with a conventional guess of vertical flare height, when flying a standard 3º (1:20) approach path.)

A sealed and painted runway offers a calibrated ruler that removes all guesswork. For C172 and similar types, the ‘top’ of the first centreline mark beyond the threshold ‘piano keys’ at 300ft/90m from the threshold and runway numbers is suggested as Aim Point 1. This provides approximately 10ft/3m main gear threshold clearance.

The flare cut-off point, calculated and rounded to 100ft before Aim Point 1 (the C172 previously calculated and rounded flare cut-off distance), is located at the ‘bottom’ of this centreline mark (200ft/60m from the threshold). Aim point 2 is selected, as usual, on the runway centreline (i.e., on the ground) at the upwind threshold.

For smaller 2-place airplanes, such as light sport aircraft (LSA) or airplanes like the B77, C150 or PA38, the flare cut-off point would be around 60-80 ft/18-25m short of the same aim point 1.

For all other larger types of airplanes, a greater understanding and the one-off pre-calculation of these points, for each different airplane type/size, is necessary and it for this reason that the Jacobson Flare App was developed. We strongly recommend it, for the cost of flying just one less-necessary circuit.

We invite you to download and explore the Jacobson Flare LITE version, but please understand that this LITE version cannot and does not contain the comprehensive information that resides in the Jacobson Flare App for iOS.

Note: On mobile phones and tablets, it is suggested that the Jacobson Flare LITE is opened in a PDF reader such as Adobe Acrobat. After the embedded video in the PDF is played, selecting ‘DONE’ should return the reader to the PDF, to enable further progress through the presentation.

No thanks … We are too busy! Does that ring any alarm bells?

No thanks … We are too busy! Does that ring any alarm bells? – It should.

Many might argue that our lives in general and our working lives in particular, seem busier today than ever; with more responsibilities than ever.

When you’re busy, it is a perfectly normal response to not want to be bothered by fresh thinking, on something that you thought was settled years ago.

But is it always a sensible response? Perhaps not.

When it comes to landing an airplane – of any size – how come it still comes down to an educated guess, regarding when to commence the flare, how much to flare and how fast to flare the airplane? Especially when EVERYTHING ELSE in aviation is very well defined and documented.

Why is it that flight training manuals – whether from manufacturers, aviation authorities or flight training organisations – contain little useful information on HOW to land an airplane, when those same manuals discuss ALL other topics so very well?

Perhaps the answer is because all those other topics are based on fact, whereas discussion around the landing manoeuvre has been based historically on opinion, feel, judgment, repetition and experience – NONE of which can be taught – handed on, unchallenged, for over 100 years. We all had to ‘get the hang of it.

Perhaps this also explains why the quality of landings, worldwide, is so inconsistent, often with sad and expensive results.

We invite you to take a few moments to check out www.jacobsonflare.com and consider the answers to these questions.
