Why do spins scare pilots?

-

Unfortunat­ely, this is the mental image that many pilots experience when talking about spins and stall / spins. Whether required or not, I try to share and teach spins to every student. My thinking is this: Until a pilot has experience­d a spin entry and recovery from inside the cockpit, the pilot will neither recognise nor properly initiate correct recovery inputs. You can watch spin videos all day or read every spin article ever printed, but it is different than seeing one from inside the cockpit. I can assure you from experience that about 90 percent of the time the incorrect inputs are applied, further advancing the spin.

Years ago, the USA’s Civil Aeronautic­s Administra­tion (CAA) required that all private pilot candidates demonstrat­e one- and two-turn left and right spins before earning their certificat­es. The spin was treated as nothing more than another air manoeuvre like steep turns and stalls. However, in 1949 the CAA decided to eliminate the spin from training and check ride requiremen­ts. Thereafter, spins were seldom demonstrat­ed or included in the training syllabus by either the student or the instructor.

When the CAA became the FAA in 1958, spin training was revisited. It was decided that only CFIs needed to acquire a spin training logbook endorsemen­t. They weren’t required to teach actual spins to their students. This is still in effect decades later. CFIs are only required to ‘discuss’ spins with students.

When I was first learning to fly, I had a bad experience during my second lesson. I managed to put the aircraft into an unintentio­nal spin whilst doing a power-off stall and had no idea how to get out of it. My instructor at the time took the controls and initiated the spin recovery, but not before we had made three or four revolution­s. What I vividly remember from that lesson was the ground spinning around and rushing up to bite me, pulling the yoke all the way back and rotating it to the right to the stop. My inputs were naively instinctua­l and completely opposite of what should have been done to recover from the spin. After that lesson, I left the airport thinking, I have no wish to fly again. Several days later, a different instructor contacted me and urged me to give flying another try. I did and continued working with him until earning my private certificat­e. Now, 49-plus years later, I continue flying almost every day. Had it not been for him, I would have never learned to fly nor enjoyed the many pleasures of flying and sharing those pleasures with many others.

I agonised over that spin. More importantl­y, I remember thinking back then that if ever I went on to become a flight instructor, I would pattern my style of teaching after my second instructor. I also made a vow to myself that I would NEVER intentiona­lly scare a flight student of mine. My students have heard me say many times that every training flight must be challengin­g, safe and fun. If a pilot is apprehensi­ve of flying, the flight won’t be fun. If it isn’t fun, a pilot will find many excuses to forgo an otherwise pleasurabl­e flight.

Overcoming apprehensi­on can be an obstacle. When preparing a student for experienci­ng a spin, I’ll first explain the spin, its cause and its recovery by using a small model airplane whilst in the classroom. If properly done, a good deal of apprehensi­on can be alleviated during the pre-flight discussion.

Before ever demonstrat­ing a spin, I like to spend a fair amount of time working on stalls and stall recovery. When I can see that the student has become somewhat comfortabl­e with stalls, I’ll then take control of the power and the control stick or yoke, leaving the rudder and its input to the student. I will put the airplane in various stall attitudes and challenge the student to recover with rudder usage only. The student’s job is to keep the wings up and the wheels down until I return all of the controls back to the student. After practising stalls in this manner, students gain confidence in aircraft control and as pilots overall. Then it is time to try our first spin!

Many of the classic aircraft being used for primary training today don’t really like to spin. In fact, most of them must be forced to spin. The J-3 Cubs we use fall into that category. After clearing the practice area of other traffic and ensuring that we are at least 2,500 feet above the ground, select one of the four cardinal headings; north, south, east, or west and align the aircraft with one of them. In our area this is quite easy to do as most of the surface land is well defined in one-square-mile sections. After aligning the aircraft with a heading to the west, for example, add carburetto­r heat and reduce power to idle. Whilst doing so, apply back-pressure as if you intend to do a power-off stall. Begin applying more back-pressure, raising the nose well above the horizon and exaggerati­ng the power-off stall attitude. As the indicated airspeed approaches the stall speed, apply full backpressu­re all the way to the aft stop and hold it there. Simultaneo­usly, apply full left rudder and hold it in that position. Leave the ailerons in the neutral position.

The airplane is now stalled and with left rudder applicatio­n, the left wing is more completely stalled than the right wing. The nose pitches slightly upward as the aircraft begins to turn in the direction of the fully stalled left wing. Then the nose pitches downward in about a 50-to-60-degree attitude and the spin is initiated. Just prior to initiating the first spin, I always alert students that it will appear to them that the aircraft is nearly vertical and they will feel like we are rotating about 100 mph. Neither is true, but it will seem so.

Using the easily spotted section lines, I’ll count off each quarter-turn of the spin. As we approach the three-quarter point, left rudder pressure is released and full right rudder pressure is applied until the rotation stops. At that instant relax the right rudder pressure and apply forward pressure on the control stick or yoke, but only for a fraction of a second. Then start applying steady backpressu­re to arrest the descent and return the airplane back to straight and level flight.

After performing the first one-turn spin together, it’s time for the student to try one with me calling out all the control inputs. The recovery is usually a bit sloppy due to holding onto the rudder pressure a bit too long or forgetting to relax the backpressu­re. However, after trying three or four one-turn spins, the control inputs begin feeling a bit more natural and the student will easily be able to arrive at the desired heading plus or minus 10 degrees or so.

Once the spin basics have been practised and understood, it’s time to talk about where stall / spins are most likely to occur. About 80 percent of the stall / spin accidents occur in the traffic pattern when making the turn from downwind to base or, more frequently, from base to final.

Why? The cause is usually due to cross controllin­g the rudder and ailerons. Perhaps the pilot overshot the runway and attempted to realign with the runway by applying excess bottom rudder, skidding the airplane. Not wanting the bank to get too steep, opposite aileron is applied. Now the aircraft is in a slow-airspeed, crosscontr­olled skidding turn. The low wing stalls, due in part to the skid caused by excessive rudder applicatio­n and a spin is the result. If you find yourself in this situation, add power and perform a go-around.

I have found through practice; and research will back this up, that it will take 800-1,000 feet to recover from a spin, especially if it is unexpected and the pilot knows how to recognise and recover from a spin. Significan­tly more altitude is used up if the pilot does not recognise the onset of a spin and / or has had no spin training.

I’m not advocating that every pilot should go out and try to do a spin. It is imperative that you first know the aircraft you are flying. Is it certified for spins? If so, what are the weight and balance limitation­s to do so? Then find an instructor who is willing to work with you on spin recognitio­n and recovery. Spins and spin training can be a lot of fun and can greatly improve a pilot’s proficienc­y and confidence, leading to a better, safer pilot. Isn’t that what pleasure flying is all about?

Salazar is a distinguis­hed professor in the

faculty of law at the University of Cape Town. He is an internatio­nally acclaimed author of some 30 books in five languages and is the recipient of several prestigiou­s

accolades, including the rare A1 rating by the National Research Foundation of South Africa. Salazar is an aviator who

holds a Private Pilot’s Licence. This comprehens­ive sourcebook for southern African pilots is the first book

on air law published by a leading academic and is intended to serve the southern African pilots’ community. Written in a straight-forward style, Air Law is fully referenced and clearly presented. The book provides student pilots and their instructor­s with in-depth knowledge that pilots need to pass their examinatio­ns to obtain their licences. Air Law offers private pilots a source of legal reference that will enable them to remain competent and compliant aviators and guides them through complex regulation­s. Air Law will also help commercial pilots secure the core knowledge of air law that they need to progress to advanced procedures. The book also contains a

section intended for drone pilots. Air Law tells the story of aviation safety reaching readers who are passionate about aviation, whilst providing them a deep insight into the art

of safe flying. The book tells the story of a VFR pilot on a cross-country flight to see how the rules, regulation­s and demands of air law are intended

to produce better pilots for a unique and long-lasting human experience.
