This document is intended for the use of independent testing laboratories qualified for flight testing paragliders. 2 Normative references The following documents, in whole or in part, are normatively referenced in this document and are indispe

24、. 3.1 paraglider ultralight glider with no primary rigid structure, for which take-off and landing are on foot, with the pilot (and potentially one passenger) carried in a harness (or harnesses) connected to the wing 3.2 harness assembly composed of straps and fabric for supporting the pilot in the
25、seated or semi-recumbent or standing position Note 1 to entry: The harness is attached to the wing via two rings or connectors; it can also be integral with the wing via risers. 3.3 emergency parachute emergency device intended to slow the descent of a paraglider pilot in the event of an incident in
26、 flight, which is deployed by the pilot by an intentional manual action Note 1 to entry: This may be unsteered or steerable. 3.4 controls primary steering and speed controls which are designated as such by the manufacturer 3.5 trimmer lockable pitch adjustment system Note 1 to entry: Action by the p
27、ilot is required to return it to the initial position. BS EN 926-2:2013EN 926-2:2013 (E) 5 3.6 accelerator secondary pitch control mechanism generally operated by the feet, which automatically returns to the initial position when the action of the pilot stops 3.7 accelerator fully activated when the
28、 mechanical limits of the glider are reached and further action on the accelerator does not result in a further decrease of the angle of attack 3.8 action of the pilot any transfer of weight, action on the controls, the accelerator or on the trimmer 3.9 normal flight flight condition in which the pa
29、raglider is fully inflated and is following a trajectory close to straight flight (at a speed close to trim speed) without any action on the part of the pilot Note 1 to entry: A small number of cells may still be collapsed. 3.10 spiral dive flight condition in which the paraglider is fully inflated
30、and is following a circling, steep, nose down trajectory with pitch angle of more than 70 and the angle of the span relative to the horizontal between 0 and 40 as illustrated in Figure 1 BS EN 926-2:2013EN 926-2:2013 (E) 6 Key a angle of the span relative to the horizon b pitch angle Figure 1 Illust
31、ration of a spiral dive 3.11 spontaneous recovery when the paraglider returns to normal flight without any action on the part of the pilot BS EN 926-2:2013EN 926-2:2013 (E) 7 3.12 front collapse folding under of the leading edge such that the top surface is visible to the pilot Note 1 to entry: Defo
32、rmation of the leading edge is not considered to be a front collapse. 3.13 cascade transition from one involuntary abnormal flight condition to another involuntary abnormal flight condition 3.14 minimum speed slowest airspeed maintainable without entering a deep stall or full stall 3.15 trim speed a
33、irspeed of the paraglider in straight flight without activating the controls or the accelerator 3.16 maximum speed airspeed of the paraglider in straight flight with the controls in the zero position and the accelerator fully activated Note 1 to entry: Maximum speed is only used when referring to gl
34、iders equipped with an accelerator. 3.17 low speed airspeed of the paraglider in straight flight with the controls at 50 % of travel between the zero and the symmetric stall position, i.e. 50 % of the symmetric control travel 3.18 weight in flight total weight (mass) of the pilot and his entire para
35、gliding equipment (including the glider) ready to fly Note 1 to entry: For the purposes of this document, masses are indicated in kilograms rounded to the nearest integer value. 3.19 additional lines cross lines or folding lines used to help the test pilot in achieving specified manoeuvres 3.20 cros
36、s line single line going from one riser to any position on an opposite A-line or A-line attachment point 3.21 folding lines copy of the complete geometry of the A-lines (angle, cascade, length) used to help the test pilot in achieving specified manoeuvres 4 Requirements 4.1 Paraglider classes The cl
37、ass of a paraglider is determined according to 4.2. The class is intended to give pilots a guideline on whether a paraglider is suitable for their level of skill (see Table 1). BS EN 926-2:2013EN 926-2:2013 (E) 8 Table 1 Description of the paraglider classes Class Description of flight characteristi
38、cs Description of pilot skills required A Paragliders with maximum passive safety and extremely forgiving flying characteristics. Gliders with good resistance to departures from normal flight. Designed for all pilots including pilots under all levels of training. B Paragliders with good passive safe
39、ty and forgiving flying characteristics. Gliders with some resistance to departures from normal flight. Designed for all pilots and may be suitable for pilots under training if recommended by the manufacturer. C Paragliders with moderate passive safety and with potentially dynamic reactions to turbu
40、lence and pilot errors. Recovery to normal flight may require precise pilot input. Designed for pilots familiar with recovery techniques, who fly “actively” and regularly, and understand the implications of flying a glider with reduced passive safety. D Paragliders with demanding flying characterist
41、ics and potentially violent reactions to turbulence and pilot errors. Recovery to normal flight requires precise pilot input. Designed for pilots well practised in recovery techniques, who fly very actively, have significant experience of flying in turbulent conditions, and who accept the implicatio
42、ns of flying such a wing. 4.2 Classification of flight characteristics When testing in accordance with the procedures 5.5.18.1 to 5.5.18.23, various aspects of the paragliders behaviour are measured. These measurements are classified according to 4.4.1 to 4.4.24. The class of a paraglider according
43、to this document is determined by the highest classification obtained, i.e. by the highest level of pilot skill required (see Table 1). 4.3 Failure The glider has failed the test procedure if either: a) as a consequence of tests 5.5.18.1 to 5.5.18.23 any failure of any part or component occurs; b) t
44、he results of any of the tests 5.5.18.1 to 5.5.18.23 are not classified A, B, C or D. NOTE In the classification tables in 4.4.1 to 4.4.24 the letter “F“ (failed) is used to identify unacceptable behaviour. 4.4 Flight characteristics 4.4.1 Inflation/take-off When tested in accordance with 5.5.18.1,
45、it is found out how difficult it is to take-off with this glider (including checking for undesirable tendencies). The behaviour of the paraglider is measured according to Table 2 and classified according to Table 3. BS EN 926-2:2013EN 926-2:2013 (E) 9 Table 2 Measurements and possible ranges in the
