1 Conference FEDERATION FRANCAISE D’ULM Symposium on the safety

2 Actual situation The heavy accidentology progressed in the ten last years in a very favorable way The level of safety is reached and is maintained with that of certified light aviation The light accidentology (without victim nor collateral damage) remains higher –Regarded as familiar to ultra light aviation, this parameter is however not regarded as worrying..... FOR THE MOMENT.

3 Findings Safety seems not to progress It does not decrease but the progression of the accidents follows from now on that of the number of practitioners Situation in France

4 Findings Safety in instruction is alarming Statistically, the instruction is no longer safer than the other federal activities (+/- 12% of the flights which causes 18% of the fatal accidents - annual report BEA 2009) However it is the portion of the activity theoretically best framed

5 Circumstances of the accidents Not the factors on which the ULM is systematically attacked causes the significant accidents The indisputable structural fractures in stabilized flight are extremely exceptional

6 Circumstances of the accidents Not the factors on which the ULM is systematically attacked causes the significant accidents Engine failures did not result in more really serious accidents than in the cases of certified planes

7 Circumstances of the accidents Not the factors on which the ULM is systematically attacked causes the significant accidents The proven weaknesses of medical nature are exceptionally and are not greater than in the certified aviation

8 Circumstances of the accidents Not the factors on which the ULM is systematically attacked causes the significant accidents Errors in mastering the basic control and operational techniques, characterizing a lack of training, are fewer than in the other branches of light aviation

9 Circumstances of the accidents Not the factors on which the ULM is systematically attacked causes the significant accidents Structural fractures Engine failure Medical shortcoming Lack of training ARE NOT THE MAJOR CAUSES OF THE ACCIDENTS

10 Conclusion The causes are in a very great part identical to those of the other branches of the leisure aviation

11 Conclusion If we assume the pilot is qualified and sufficiently trained Largest vulnerability is situated in the field of the decision-making Has to do mclusionore or less with the level of exceeding the self-confidence or stress

12 Circumstances of the accidents Intention of flight too ambitious with respect to the performances Intention of flight too ambitious with respect to the competences Intention of flight incompatible with the regulation Can cause : Flight in incompatible meteorological conditions Voluntary operations in the limit of flight envelope Evolutions with low height Voluntary violation or unconscious of the regulation and the good practices

13 In accidentology When the major causes concern violations of the rules, A more strict legislation does not bring additional safety

14 Circumstances of the accidents Exaggerated confidence To the GPS To the parachute Encourages to The continuation of dangerous options Sometimes unrealizable

15 The parachute Look to the video about the release of parachute Lien web

16 The parachute How to analyze this example? The pilot was certainly saved, BUT: Because of the structural rupture in dynamic evolution, at the time of the opening, the conservation of the attachment of the parachute with what remains of the cell wasn't guaranteed

17 The parachute How to analyze this example? The pilot was certainly saved, BUT: It takes 8 seconds between the unfolding and the stabilization of the parachute. The loss of altitude was estimated at 450 feet

18 The parachute How to analyze this example? The pilot was certainly saved, BUT: The place where the ULM touched the ground was far from being ideal

19 The parachute The parachute has certain limits of use which must be respected (min height, speed, max weight, …) The only fact of its deployment can’t be enough to save you, even when its specifications are respected We have at least one example of non- deployment because the parachute was damaged by the collision in flight which required its opening

20 The parachute The parachute is not a safety device ! Contrary to a balustrade which can prevent you from a turn over in the vacuum, and with a non- skid which can avoid you from slipping, THE PARACHUTE CANNOT AVOID THE ACCIDENT

21 The parachute The parachute is not a safety device ! It is only a possibility of rescue But at the same time let us remind that it is also an ultimate chance which saved more than 80% of the pilots who made use of it

22 BUT The parachute being only a possibility of rescue The safety of the flight is thus assured only if it is carried out from beginning to end, as if there was no parachute

23 End THE END
