1.5. The test referred to in point 1.4.2 must be preceded by a test in which an initial load of three times the maximum permissible vertical force (in daN, equal to g · S/10) recommended by the manufacturer is applied in a gradually increasing manner, starting from an initial load of 500 daN, to the reference centre of the coupling device.

Other key features include a fully marinized structure and engines for continuous corrosion resistant operations in a maritime environment; extensive use of composites to increase resistance to corrosion fatigue; state-of-the-art crash-worthiness features in the areas of structural design, load attenuation, passenger safety, payload retention, fire suppression, and emergency escape; triple redundant digital fly-by-wire flight controls and hydraulic systems; Rolls-Royce AE 1107C engines, which share the same engine core as found on the CC-130J; modern avionics with glass cockpit displays; a number of radar options to include weather, maritime search, or terrain-following and terrain avoidance; an ice protection system, which includes ...[+++]both anti-ice and de-ice capabilities certified into known moderate icing—and most of our testing of that system was actually performed in Shearwater; and an open passenger and cargo cabin with roller rails, winch, hoist, and a rear loading ramp to provide the SAR techs with the clearance required to safely perform all necessary ground and airborne tasks. The V-22 program is in full production.

In order to take account of various unavoidable errors due, in particular, to the measuring technique and to the increase in running speed of the engine with a partial load, a measured speed exceeding the value for the maximum design speed by 3 km/h shall be acceptable for the type-approval test.

1.6.2.The overload test involves the gradual increase of the horizontal load by increments of 5 % of the initial energy requirement up to a maximum of 20 % of energy added (see Figure 10c of Annex IV).1.6.2.1.The overload test is satisfactory if, after each increase by 5 %, 10 % or 15 % in the energy required, the force decreases by less than 3 % for a 5 % increment and remains more than 0,8 Fmax.1.6.2.2.The overload test is satisfactory if, after the structure has absorbed 20 % of the added energy, the force exceeds 0,8 Fmax.1.6.2.3.Additional cracks or tears and/or entry into or lack of protection of the zone of clearance due to elasti ...[+++]c deflection are permitted during the overload test.
