THE PARA PRO
A PARAGLIDING SAFETY AND TRAINING ANALYSIS
by Stein Arne Fossum*
The history of paragliding has been written in a few years, where new barriers have been broken virtually every day. (Today it may suffer from a hard case of the "Icarus Syndrome".) It has developed into a full-blooded aviation activity, which means that it is no longer simple and easy to learn. It has become complex and potentially more dangerous for the "self-learners", while the opposite may be true for the ones that receive proper training.
In the race for more efficient gliders and new developments (high aspect-ratio wings, power, thermal and cross country flying), one seems to forget too often that human nature needs time to learn to perform new tasks in a safe manner. The training methods are very often on the "ground skimming level", while reality calls for cross country and thermal flying.
If one looks at the history of paragliding with respect to the levels of flying that have been reached (limited to foot launched, no power paragliding), we see 5 distinct stages, similar to those involved in flight in hang gliders. However, in paragliding, the lowest two levels are combined, due to the greater ease of takeoff and landing and lower flight speeds in paragliders.
Accidents are most likely to happen when the pilot takes the step up to a higher stage.
The 5 stages of paragliding:
5. CROSS COUNTRY
4. ADVANCED SOARING
(Soaring in turbulent conditions.)
3. BASIC SOARING
(Soaring in non turbulent conditions)
2. ALTITUDE GLIDING
(Altitude and space to manoeuvre, no soaring)
1. GROUND SKIMMING
(Don't fly higher than you would care to fall!)
(this stage is combined with stage 2)
*NOTE: This article was originally written by Stein Arne Fossum when he made the PARA PRO system in 1980- 1982. The names of the stages have been updated, but otherwise it is the original text (with a few additions). At some points it therefore may seem somewhat outdated, yet the principles described herein are timeless. Note that this document only applies to foot-launched paragliding flight at this time, with no mention of tow launches.
Each stage is followed by a more complex stage (a building block system) requiring new knowledge and skills. It is a natural "ladder" where a student should climb to progress safely in his paragliding career.
We have additional stages like Aerobatics, Experimental and Power, all of which I personally consider unsafe for the general pilots at the present time. They should therefore only be performed by specialists using a strict professional program until safe methods are found to make them available to everyone.
In addition to the stage system above, there are also other stages or steps a pilot may take, such as changing to another harness system, or learning to fly a new site or a new glider.
Each time new stages are pioneered, or are being reached by the "self learning" pilots, there are an increase in accidents. Some of those accidents are unavoidable because of the pioneering nature of it (Lillienthal was the first one), while others could have been avoided simply by proper training.
If one analyses why most accidents caused by "pilot error" happen, one finds that they happen either because the pilot tries to perform a task or meet a condition he/she is not able to master, or he/she simply does something that should not be done.
Today we have all the material necessary to avoid most such accidents, either by the knowledge the paragliding community has collected itself or by the available knowledge through other aviation activities. Either we know how a task should be performed correctly or we know that there are clear limitations that we cannot safely exceed. (One sample of the latter is cloud flying. Any sane motor or glider pilot knows that this is dangerous, and it is hence unnecessary for paraglider pilots to rediscover this fact by killing themselves).
Today, paragliding, along with other aviation activities, has most of the information needed to progress safely through the flying stages. All that is needed is to put all together in a training system.
Let us have a closer look at the model of the stages:
The 5 stages of paragliding:
Accidents are most likely to happen when the pilot takes the step up to a higher
stage. A training system should be designed to smooth out these steps with a
natural progression to higher pilot ability. We fill in these steps with instruction.

4. THERMAL SOARING
3. RIDGE SOARING
2. ALTITUDE GLIDING
1. GROUND SKIMMING
(combined with stage 2)
A PILOT'S ABILITY to fly paraglider can be broken down to 4 QUALITIES that we
SKILL: Since paragliding is a practical activity, a pilot's ability can best be measured by his skill, which means his way of performing manoeuvres, links of manoeuvres and tasks, and how he masters flying conditions and new situations. He certainly also must show good AIRMANSHIP but that is not easily measured and difficult to diagram. A good instructor however is able to spot good airmanship often before the pilot is even in the air.
KNOWLEDGE and EXPERIENCE are only "tools" used to improve a pilot's SKILLand AIRMANSHIP and hence his ABILITY as a pilot. They are however of good value in the learning process and their value as such can hardly be overestimated. Left alone by themselves they are meaningless in measuring the pilot ABILITY.BASED on the above "facts" or statements, I have developed a training system, built on the 5 STAGES of PARAGLIDING as a natural progression for a pilot. I have also based the system mainly on the development and measurement of the pilot's SKILL, although the other 3 qualities have found their place.
For instance, AIRMANSHIP is expressed by the fact that the pilot has either a STUDENT LICENCE, which means that he lacks the necessary AIRMANSHIP to take care of his own and others’ safety, or he has a PILOT LICENCE, showing he has the necessary AIRMANSHIP. In other words, a student pilot is one that is under a training system, controlled by an instructor, and all his flying shall be in accordance with the instructor guidelines. A pilot licence shows that the holder is a pilot that is mature enough to take care of his own flying, seeking further instruction when he feels he needs it. A pilot licence does not mean that the holder is someone that does not need more instruction because "he knows it all", but merely that he can take care of himself at the stage he is at. When he wants to progress to a higher stage he seeks instruction, before he goes out on his own flying at that stage.
THE COLOUR CODES (or "Black belt in Paragliding"): The stages in the system are colour coded for easy identification. The idea is that the pilot (or student) will wear visible markings that identify him as a Student or a Pilot, as well as the stage he is on (signed off by an instructor). Apart from being a good site control system it has its values as a training aid. It is motivating and it gives the students and pilots insight in what they are up to by breaking down the way to the top into easily identifiable stages or blocks that seem attainable by most people.
Note: The stages are given colours from yellow to brown. A "black" grade or Master grade may be considered as the top level. This grade should express the ultimate in Airmanship, Skill, Knowledge and Experience.
PARA PRO, general description
The objective of this program is to aid and assist the participants to progress safely in, and enjoy, the sport of paragliding, and become true airmen.
Which means that they must be able to enjoy the beauty and freedom of the sport, and not risk injury or restrictions due to their own and others’ lack of will and ability to take care of their safety, enjoyment and freedom.
The ability of an airman is based on knowledge, skill, experience, personal qualities and attitudes, which take time to develop to a standard where one is able to operate alone within the objective above.
The development of this ability is a matter of education, which is done most efficiently, enjoyably and safely through a planned program which motivates the student and pilots by helping them to reach easily definable and natural stages or goals, which gradually expands the operational freedom without jeopardising safety.
The program consists of 5 natural stages, based on the development of the sport, and which gives an excellent progression after the building block principle of learning. One progresses from the easy to the more difficult, from low to high, from basic to advanced, from simple to complicated, being careful not to leave any gaps on the way.
The program also divides the participants into students and pilots which indicated whether they are able to operate alone or not.
THE 5 STAGES
1,2. Altitude gliding Orange Student
3. Ridge Soaring Green Pilot
4. Thermal Soaring Blue Pilot
5. Cross Country Brown Pilot
A student pilot is as the name suggests under training to become a pilot. He is considered to have limited ability to take care of his own and other people's safety.
This means that he has not developed enough ability to evaluate all elements involved with regard to safety and based on this, make safe and sound decisions and act accordingly, without the supervision of an instructor.
A pilot should be able to take care of his own and other people's safety within applicable rules, regulations and code of good practice, while operating alone requires higher stages than they are rated for.
This means that he must be able to evaluate all the elements involved with regard to safety, and based on this make safe and sound decisions and act accordingly, on his own, or to obtain further instruction, information and assistance at his own discretion.
Recommended training and safety limitations
Students should always fly under the supervision of an instructor. Before all the rating requirements are met they should always fly under the direct supervision of an instructor.
Students should only fly paragliders and harnesses suitable for students and which on they have been checked out on by the instructor. They should only do tuning and repairs when approved by the instructor.
Students should only fly demonstration or competition flying at the stages they are rated for and always under the direct supervision of an instructor.
Pilots are expected to be familiar with and to follow all applicable national aeronautical regulations and local flying site rules.
Pilots should not participate in demonstration, competition or other organised flying which requires higher standards than they are rated for.
Minimum age: To fly paraglider: the minimum recommended age is 16 years old, with the written permission of parent or guardian when below 18 years.
PARA PRO, DESCRIPTION OF STAGE ELEMENTS:
Students stage 1, 2 and 3 should be given the necessary lectures, briefings, oral discussions and written tests to ensure that the required knowledge needed to meet the objectives of the applicable stage, is acquired. The listed requirements are a guide to meet those objectives. They should not restrict anybody from giving additional instruction if found necessary. The methods of instruction may vary and are left to the discretion of the organiser/instructor.
Stage 3. Before a student is signed off to become a pilot, he should pass a written test on air law, applicable rules and regulations and code of good practice, to ensure that he has all the necessary knowledge to operate alone, safely and correctly at sites and in the air.
Pilots stage 4 and 5, may at their own discretion acquire the required knowledge, either through attendance of lectures, briefings or through oral discussions and group or personal study.
Before a student or a pilot is signed off at an applicable stage, the instructor or observer must be convinced that he meets the required standard of knowledge.
Students stage 1,2 & 3, should be given the necessary instruction in each of the practical skills. Before a skill is actually performed, the student should be given a theoretical briefing in the basic theory, the purpose, normal procedures, mistakes, faults and dangers and their corrections, as well as the acceptable safe criteria of performance.
Each skill should be practised until the instructor is convinced that it is mastered within correct and safe procedures and limitations for the applicable stage. The skills may be signed off progressively as the above criteria is met. A special flight test is hence not necessary.
Pilots stage 4 & 5, may at their own discretion, within acceptable safe methods, acquire the necessary instruction for each practical skill. Before the skills are signed off, they should be demonstrated to an instructor or observer, who should be convinced that they are mastered within safe procedures and limitations.
Experience is not, by itself, a measurement of pilot ability. It shall, however, ensure that the knowledge, skills and airmanship have been practised a minimum number of times in various situations. Exercise, drill and practice are important in the learning process to meet the objective of all true learning which is: to effect behavioural changes.
The experience requirements should be documented by a logbook or reliable witnesses. The instructor or observer should be convinced that the minimum requirements are met or he/she must require further proof.
The instructor or observer should be convinced that the student or pilot has the ability to take care of his own and others’ safety at the applicable stage, within applicable rules, regulations, recommended safety limitations and code of good practice.
PARA PRO, STAGE 2, LOW FLIGHTS & ALTITUDE GLIDING
Low flights is gliding near the ground over smooth terrain, normally not above 5 meters. Altitude gliding is gliding with enough height and distance from the terrain to be able to manoeuvre relatively freely.
INSTRUCTIONAL AND SAFETY RECOMMENDATIONS:
The objectives of this stage are to introduce the student to paragliding by a progression through first low flights (the first stage) and then altitude gliding (the second stage) and make him able to practice and enjoy this within safe limitations, as well as to prepare him for the next stage.
This stage is probably the most important in the whole progression of the student, since it is here the basis for good (or bad) habits is founded. One shall in safe closeness to the ground, fly easy equipment, in easy hills and conditions, to gain confidence in flying, the equipment and also oneself and practice and learn the basic skills.
The student shall then gradually become accustomed to flying well clear off the ground, and lose possible height anxiety (allow for individual progression). One must now plan and prepare for each flight and one finds that one is actually safer with altitude that gives time and space to manoeuvre and correct for possible mistakes. One learns and practices the basic manoeuvres, such as speed control including slow flying, co-ordinated turns, and combinations of those, correction for wind drift and precision approaches and landings. The latter proves that one has mastered the other manoeuvres with sufficient planning and precision. The key word is planning that starts even before takeoff and continues all the time. One must be ahead of the events, observe, evaluate, decide and act accordingly. This "process of flying" is vital in all aviation, also on the higher stages. It is warned against attempts to take off in cross-, down-, gusty or strong winds and to fly in unstable or turbulent conditions or in lift. One should at the beginner’s hill only practice gentle turns with only small diversions form the flight path. In the intermediate hill, poor planning, preparations and takeoff techniques may have the most serious consequences. All manoeuvres should be done into the wind to avoid drifting into the hill or too far off and hence not be able to reach the landing area. Advanced manoeuvres, like 360o turns, pylon flying and slow flying should be performed with extra caution and sufficient height and distance to the terrain to allow for corrections or recovery if control is lost. Turns, downwind flying and airspeed below speed for best glide angle close to the ground should be avoided. Approach should be planned in good time, and started with good height. After all rating requirements have been met: The student should, when flying without the direct supervision of an instructor only fly in beginner or intermediate hills with light to medium (0-3 m/s, 0-15 km/h, 0-10 mph), smooth winds. Takeoffs should only be done in approximately headwind. Lift or turbulence should be avoided, or if this is not possible, flown straight through (away from the hill) to calmer conditions in order to land in the ordinary landing area. One should also avoid flying alone.
A beginner hill is a hill with smooth terrain, preferable snow, sand, grass or gravel, with a profile that allow for low flights with the type of glider in use. The takeoff and landing areas and the area between should be free of obstacles and other hazards with a good margin to either side. It should be possible to do the whole flight in close to a straight line.
An intermediate is a hill where takeoff, landing area and the flight path between them is considered to be easy and with good margins to any obstacle or other safety hazards. The takeoff area should be smooth with a profile that allows for acceleration to flying speed before getting airborne (no cliff launch). The landing area should be large and easy to reach by normal manoeuvring with a good margin of height. There should be established two-way communication between takeoff and
landing if the landing area cannot be seen from takeoff.
Before progressing to the next stage it is of vital importance that the student knows the theory as well as mastering all practical skills, especially airspeed control in the lower speed range and that he is able to recognise and correct for nearness to stalls.
This applies to both straight flight and turns. To gain a minimum of experience, the student is recommended to practice a minimum of 4 flying days and 20 flights, after all rating requirements are met.

PARA PRO Stage 2, AIRMANSHIP Requirements:

PARA PRO, STAGE 3, BASIC SOARING, GREEN.
Basic soaring is soaring in easy ridge or thermal conditions, without gusts or turbulence, well clear of the terrain, obstacles and other traffic.
INSTRUCTIONAL AND SAFETY RECOMMENDATIONS
The objectives of this stage are to introduce the student to soaring flight and to make him able to practice and enjoy soaring within safe limitations. He should also be qualified to become a pilot, with the ability to operate alone within safe limitations and to take the responsibility for his further progression.
Soaring has many stages in itself, with increasing difficulty, from easy conditions and manoeuvs with a large safety margin, to marginal or extreme conditions with minimal margins. When a pilot "masters the art", it seems quite simple and in a sense it is. This, however, should not mislead anyone into believing that it is easily mastered. Lack of knowledge, misjudgement, wrong manoeuvring, ignorance or gambling may easily end up in a serious accident. One will in this stage get more time to practice in the air and the flying can get automated. There is however less room for mistakes and errors. Therefore careful planned progression is very important. Exercises should in the beginning be simple and with large margins. Soaring requires careful preparation, good planning and ability to do precise and fast manoeuvring. Especially important is good launch technique and control in the lower part of the speed range. One must be able to fly co-ordinated turns with a minimum loss of altitude, often in marginal conditions close to the ridge while calculating drift and keeping constant lookout for other traffic and manoeuvring according to traffic rules. One must also be able to recognise all kinds
of collapses and to execute prompt and correct recovery at the first signs, with a minimum loss of height and control.
To become a pilot: One should now also be free to develop further, and one has still a lot to learn in order to be able to use the possibilities there is. One will be given possibilities that will demand very good "airmanship" including self discipline and carefulness. It can often be necessary not to fly or to fly with large margins. The point is that one must show that one is able to take responsibility and that one know where ones own as well as others limits are, and when further instruction is necessary.
An instructor will no longer be responsible. This puts large demands on one’s personality. It is warned against too fast a progression, overconfidence, inattention, ignorance, gambling, misjudgement and lack of skills. One will operate in stronger winds with smaller margins than on previous stages. Even before takeoff accidents can happen. Poor takeoff techniques, lack of control and correction of glider while running, or takeoff without a "perfect" glider can have serious consequences. One should have qualified assistance when launching in strong or gusty winds. Further one should be very careful with the conditions, which can change suddenly. Strong wind and turbulence may easily lead one to the lee side, or to drift in over dangerous/ unknown terrain. One should also avoid flying alone.
It is also warned against the so called "intermediate syndrome" or "Icarus syndrome", meaning that it is easy to believe that one now knows and masters everything, and that neither oneself or the equipment has limitations. (It is well known that Icarus was the first who killed himself because of this attitude.)
The student (before stage 3 is attained) should only fly:, with instructor present, in easy smooth conditions with a wide lift band or in smooth thermal conditions. This will allow him to manoeuvre with a good margin to other traffic and the terrain. He should be careful not to turn before he is established in flying position with good control of airspeed and direction. He should not try to return to a lift band he has flown out of. Ridge soaring in marginal lift, in strong wind (above 7 m/s, 25 km/h, 15 mph), in turbulence, cliff launches, crosswind launches, top landings or landings into the hill (hillside landings) are also not allowed. After all rating requirements have been met one can fly freely within the safety limitations, as long as a higher stage is not required by other rules or regulation. One will have the responsibility to seek further instructions when necessary. It is recommended in the beginning to use the rules for students (above) as a guidance for safe flying.
Only experienced pilots should fly at advanced sites close to the ridge, in marginal, strong or turbulent conditions or in "heavy traffic".
Before progressing to higher stages, the pilot should have a variety of experience from different sites and conditions. The process of flying should be automated, so that reactions are fast and correct in the different situations/exercises one has to master. It is recommended to fly a minimum of 20 hours and 50 flights.
PARA PRO Stage 3, KNOWLEDGE Requirements:
1. Repetition of stage 2 theory.
2. Stalls and collapses: In takeoff, in gusts and turbulence. In lift gradients. Turning in lift gradients. In wind gradient. Turning in wind gradient (downwind). Secondary stalls.
