Inward Rolling Turn

The rolling turn or rolling circle is the king of aerobatics. I remember how I worked so hard to perfect it and thought I was flying it quite well, I was always a bit miffed that the judges didn’t agree but several years later I realised how much better I was able to fly it! […]

Positive Flick Rolls

A well executed flick roll (called ‘snap roll’ in the USA) is a truly spectacular figure.  It should be explosive and dramatic but also meet the judging criteria. The figure is executed so rapidly that it is difficult to judge. In an effort to improve judging accuracy, judges can allocate a “Perception Zero” or PZ. […]

Spinning Part 5, Advanced Fractions

One and a Quarter and One and Three Quarter Turn Spins When spinning, the trajectory is not vertically down but forward and down. This makes 1/4 and 3/4 fractions of spins more complicated because the heavy nose follows the trajectory after recovery causing, in a left spin, the right wing to be high and for […]

The Quarter Clover

The Quarter Clover The quarter clover is a common airshow figure and regularly seen in BAeA competitions in the Sportsman category and has been a figure in the BAeA Club known sequence.  In recent times, at Air Shows, it has also become known as a “Bent Loop” Simply put, a quarter clover is a loop […]

Hasell Checks and Why Do we Do Them

Aimed at – entry level aerobatics HASELL checks are designed to make sure everything is good prior to doing stuff that might result in the aircraft entering an unusual attitude, being on the fringes of control or being out of control and consuming a large amount of height during the recovery process. Of course the […]

Flying in the Aerobatic Box

Flying in the Aerobatic Box I fly with students as a safety pilot in aerobatic competitions on a fairly regular basis. Flying as safety pilot provides a unique experience because I am watching somebody compete, somebody I have probably trained and know their flying abilities well. Their actual performance on the “big day” is often […]

Why do a Tail-Wheel Course?

Being an aviation enthusiast, I enjoy bringing the joy of aviation to others. I feel that the enjoyment of pure flying is being forgotten or lost. In most cases todays pilots just do not realise what they are missing. I would like to describe the merits of our magnificent 1946 Cessna 140 so that others […]

Formation Flying with the British Aerobatic Academy by Robert Hunter

We are at 2000 feet, G-EEEK, the British Aerobatic Association’s Extra 200 flying straight and level, buffeted slightly by unseen turbulence.    I am concentrating hard, trying to stay one step ahead of my aircraft.   Limited though my skills are, flying straight and level would not ordinarily be that much of a problem.  But […]

The Stall Turn or Hammerhead

The stall turn is a magnificent aerobatic figure.  It looks graceful and elegant when flown well but is actually very challenging to fly perfectly and the further up the aerobatic ladder you go, the more challenging it becomes with ever more difficult embellishments and energy management issues. The vanilla stall turn has a k factor of […]

Navigation – Using Mental Dead Reckoning to Calculate Drift

The Dalton Computer or Whiz Wheel is certainly a very good tool, perhaps better than an electronic calculator because it is visual and allows you to check your answers “by inspection”.  A much easier technique however, is Mental Dead Reckoning.  With practice MDR is easy and quick. In this short blog, I will develop the theory from the […]
