The Videos: B777-300ER Simulator KLAX 25L Los Angeles Ca USA

This approach was flown in a state of the art flight simulator by the author, highly experienced but not endorsed on the B777 or any wide-bodied jet transport and retired from airline service for four years, at the time. The universal application of the Jacobson Flare principles is clearly demonstrated, despite this lack of qualification and recent experience.

One of six fully captioned videos within the app; others include the C172 landing on an uphill grass airstrip and on paved runways and the B737-400 and A380-100, illustrating clearly how the Jacobson Flare may be applied to successive airplane conversions throughout a pilot’s career, on the many varied airfields around the world. This includes grass, gravel or even snow-covered unmarked airstrips by day or night and also water alighting areas for seaplanes.

There is always a way of assessing distance on these surfaces from their contrasting surface shades, or various-shaped edge markers or lights; any longitudinal errors caused by inaccuracies in estimation are made tolerable, through the 1:20 correction, in vertical height terms – that is, a longitudinal error diminishes approx 20 times, when flying a 3° flight path.

Chapter 4. When to Flare: Expansion Pattern as a Cue to Flare

The aim point has long been regarded as the centre of expansion of a flow pattern – a visual effect known as motion parallax, familiar to generations of pilots as that ‘looming’ or ‘rushing’ or ‘explosive’ effect, seen as we approach the runway.

Here we discuss this most useful effect in detail and explain how it provides a perfect visual fix for the flare point as the airplane approaches the runway. An educated guess of flare height is not the only arbiter in assessing when to commence the flare. The flare point can now be quantified, through a simple and precise observation.

Chapter 5. How to Flare: The 4-Second Flare

View the flare in elevation, as the the pilot’s eye path traces a classic exponential curve.

Interactive in-app slides reveal real-time 1-second runway distance increments, defining the entire flare manoeuvre from the flare point through to a predictable touchdown of consistent quality.

This easy to follow concept of flaring over 4 seconds provides a practical sub-structure for flare training. Learn why The Jacobson Flare has been adopted as a standard landing technique by several major training organisations and by thousands of professional and recreational pilots.

Comprehensive Reference Section: Runway Markings

The Jacobson Flare app for iPad includes a comprehensive aviation reference section.

Learn about the importance of the correct seating position. There is more in this than meets the eye.

Review international ICAO-A runway markings and their variants. Learn to view them as useful rulers to be used to our advantage – a better understanding improves touchdown precision and consistency.

Explained in detail: ILS, PAPI and T-VASIS approach slope indicator systems – their value and their limitations; step by step ‘real-world’ elevation and cockpit view diagrams provide an excellent training tool bonus.

Pilots with a thirst for the finer detail can explore flare cut-off geometry and the mathematical derivation of the formulas developed and used to quantify The Jacobson Flare. Other pilots need not be daunted – the calculation is a one-off, per type.

Five Indispensable Calculators: ILS, PAPI and Flare Point

Our in-app ILS, PAPI and T-VASIS calculators make light work of understanding and comparing different resulting approach slope indicator aim point positions, including the vital correction for runway slope.

Easy to use flare point calculators plot visual flare point cues on any chosen runway* with absolute accuracy. The system is designed perfectly to be used with any fixed wing airplane. * This applies equally well on grass and gravel airstrips, by day or night.

Save your own airfield database notes on calculated flare point and runway aim point data; recall them at any time.

Professionals will find the ILS, PAPI and T-VASIS calculators indispensable for day to day operations, as these convert published TCH and MEHT data to a longitudinal pilot-eye aim point, for immediate and simple comparison with the selected or operator-nominated visual aim point. For the first time, runway slope is taken into consideration – this is a significant refinement and explains the reasons for long (deep) touchdowns and heavy wear on down-sloping runways.

The five calculators include:

1. Df calculator
When to flare an airplane greater than 12,500lb (5700kg) MTOW

2. Dx calculator
Where to aim and when to flare an airplane up to 12,500lb (5700kg) MTOW

3. ILS calculator
Compare the ILS aim point with the correct visual aim point

4. PAPI calculator
Compare the PAPI aim point with the correct visual aim point

5. T-VASIS calculator (T-VASIS is gradually being phased out in Australia)
Compare the T-VASIS aim point with the correct visual aim point
