A paragliding accident almost never has a single cause. It is a chain of decisions, and it can be broken at any link. In this module we cover the pre-flight check, the launch rules, separation in the air and risk management. Then human factors, the emergency landing, calling for help in the mountains and first aid. We look separately at what is specific to Gudauri, at working with a passenger on a tandem, and at the operator’s duties under the regulations in force. The extended version adds the chain-of-events model, accident statistics by phase of flight, an analysis of mistakes at launch and on landing, flying near rock faces and in rotor, separation in a group, obstacles and water, fatigue and fear, and detailed first-aid protocols.
The analysis of almost any paragliding accident ends the same way: there is no single cause. There is a chain of small things, each harmless on its own. Slept badly — left later — hurried at the launch site — cut the pre-launch check short — did not notice that the reserve pin had come out of its loop — flew into a sharp, narrow thermal (a rising column of warm air). No single link was fatal. The sequence was.
Hence the main conclusion of the module: to stop an accident, it is enough to break any one link. Almost always that costs a minute of time and one calm “no”.
In Gudauri the price of a mistake is higher than at flatland sites. Below the main tandem launch there are more than 400 metres of sheer cliffs. The thermals here are sharp, narrow and rough. Landing fields are few, and there is usually nowhere to land “somewhere nearby”.
In 2022 a Border Police helicopter crashed near Gudauri. It was carrying out a rescue operation searching for paraglider pilots; eight people on board died. After that the regulation of the industry was tightened. The price of a mountain rescue operation is measured in other people’s lives. The calculation “I’ll fly, and if something happens they’ll send help” is not a decision.
The model used in aviation is called the “Swiss cheese” model. It was proposed by the psychologist James Reason. Imagine several slices of cheese standing one behind another. Each slice is a layer of protection: training, equipment check, briefing, right-of-way rules, the reserve. Each has holes — weak spots. Usually the holes do not line up, and the danger runs into the next slice. An accident happens when the holes line up in a row.
The DHV — the German Hang Gliding and Paragliding Association — puts the same thing more briefly: accidents are, as a rule, caused by a chain of events and wrong decisions.
Two conclusions follow from the model. First: one hole does not kill, so looking for “the main cause” is pointless. Second: to stop an accident it is enough to close any hole — not necessarily the first one.
| Link | What it looks like | How to break it |
|---|---|---|
| The evening before | Went to bed at two in the morning | Move the flight to another day |
| The drive | Left an hour late | Say out loud: one flight today instead of three |
| The launch site | A queue, other people’s wings underfoot | Step aside and prepare there |
| The check | “I fastened the leg straps, I’m sure I remember” | Five points out loud, then a second person |
| Launch | The wing came up crooked, but “I’ll manage” | Bring the wing down, start again |
| The first seconds | Drifting sideways towards the rocks | Abort the run |
| In the air | A sharp thermal near the slope | Move away from the slope into the valley |
The most careful risk estimate to date was published in 2022 in the journal Wilderness & Environmental Medicine by Matt Wilkes’s group. The researchers combined a survey of 1,655 paraglider pilots with an analysis of a thousand incidents from a European database for 2012–2019:
| Phase of flight | Share of injuries |
|---|---|
| Landing approach and landing | 39 percent (393 cases) |
| Launch | 21 percent (206 cases) |
| Ridge soaring along the slope | 20 percent (189 cases) |
German statistics say the same. According to the DHV analysis for 2024, 385 incident reports came in: 167 with serious injuries and 10 fatal. By phase: launch — about 112 cases, landing approach — about 101, landing — about 45, leaving the slope and cross-country — about 58. Among the causes, wing collapses come first: 63 cases, 31 serious injuries, 4 fatal. Next come obstacles on approach — 40 cases, including 15 cars and 10 trees. Then stalls on approach: 13 cases, one fatal. Knots in the lines are a separate line — about 14 cases in a year.
A caveat is mandatory: these are reports, not a complete census. The DHV database contains what pilots reported themselves, and roughly half of the cases happened abroad. These numbers cannot be divided by the number of flights — the denominator is unknown.
| Part of the body | Number of injuries |
|---|---|
| Legs and feet | 287 |
| Lumbar spine | 165 |
| Arms, hands, shoulder | 146 |
| Thoracic spine | 80 |
| Chest | 69 |
| Pelvis | 55 |
| Head | 33 |
| Cervical spine | 28 |
The spine in total — 273 injuries out of 659. This is a direct consequence of how the pilot meets the ground: seated, with a vertical impact along the axis of the body. Two conclusions follow. First: the back protector under the seat is not a formality. Second: on landing you must get onto your feet in time, not take the impact with your pelvis and lower back.
Before take-off the pilot must check the wing, the lines, the pin and the handle of the reserve parachute. Radio communication is checked separately. The pin is the peg that keeps the reserve closed: while it sits correctly, the parachute will not come out by itself. Instruments are checked too — the batteries must last for the whole flight.
A separate point is weight. Every certified wing is tested at both the minimum and the maximum take-off weight of its range. The manufacturer must confirm how the wing behaves at both limits. Outside the range the wing does not behave as written in the certificate, and there are no more guarantees. If the actual loading does not match the weight limits of the wing and the reserve, flying is explicitly prohibited.
An example. The pilot weighs 85 kilograms, the equipment 20, the wing is certified for 130–220 kilograms. With a 95-kilogram passenger the take-off weight comes to 200 — within the range. With a 120-kilogram passenger it comes to 225 — already beyond the upper limit. An excess of “only” five kilograms means flying in a configuration that nobody has ever tested.
A separate word about leg straps. This is the best-known fatal mistake in paragliding, and it happens to experienced people. The pilot gets into the harness not through the legs but from above, and after lift-off falls out. In DHV accident reports such cases repeat year after year. It is caught with one movement: sitting in the harness, take hold of both leg straps with your hands and pull. Don’t look — pull.
A safe launch means three conditions at once, not one of them to choose from:
Within 30 metres of the lift-off point there must be no power lines, cable car, buildings, trees over 5 metres, boulders over a metre, rocky gullies or busy roads. The slope of the site along the run must be no more than 30 degrees.
Now about the length of the run. In light wind and at maximum all-up weight the run gets significantly longer. The lift-off speed rises with the loading, and a headwind does not add to it. All the missing speed has to be made up with your legs, so the site is chosen with a margin.
At a certified site the pilot does not work alone. The operator is required to keep two assistants to the flight director at every launch area, each having completed the relevant course. Moving to the launch position, preparing and taking off are only allowed with the flight director’s verbal clearance.
The order of actions is this. Lay out the wing, fit your equipment, switch on the radio. Bring the wing up while still not clipped into the harness, and satisfy yourself that it is in order. Look around the airspace, clip in the risers, check the connection and announce out loud that you are ready.
