Aeroplanes operated in conditions where they cannot be maintained in a desired flight path without reference to one or more additional instruments, shall be, in addition to (a) and (b), equipped with a means of preventing malfunction of the airspeed indicating system required in (a)(4) due to condensation or icing.

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.
