FAR 23.1419 : Ice protection.
[Ifcerti.cation withiceprotectionprovisionsisdesired, compliancewith the require-ments of this section and other applicable sections of this part must be shown :
(a)
An analysis mustbeperformedto establish, on thebasis ofthe airplane’s operational needs, the adequacy of the ice protection system for the various components of the airplane. In addition, tests of the ice protection system must be conducted to demonstratethat the airplaneis capable ofoperating safelyin continuous maximum andintermittent maximumicing conditions asdescribedinAppendixC ofpart25 of this chapter. As used in this section, ”Capable of operating safely,” means that airplane performance, controllability, maneuverability, and stability must not be less than that required in part 23, subpart B.

(b)
Except asprovidedbyparagraph(c) of this section,in additiontothe analysis and physical evaluationprescribedinparagraph(a) of this section,the e.ectiveness of the ice protection system and its components must be shown by .ight tests of the airplane or its components in measured natural atmospheric icing conditions and by one or more of thefollowing tests, asfound necessary todetermine the adequacy of the ice protection system–

(1)
Laboratory dry air or simulated icing tests, or a combination of both, of the components or models of the components.

(2)
Flight dry air tests of the ice protection system as a whole, or its individual components.

(3)
Flight testof the airplane orits componentsin measured simulatedicing condi-tions.

(c)
If certi.cation with ice protection has been accomplished on prior type certi.cated airplanes whose designs include components that are thermodynamically and ae-rodynamically equivalent to those used on a new airplane design, certi.cation of these equivalent components may be accomplished by reference to previously ac-complishedtests, requiredinSec.23.1419(a) and(b),provided that the applicant accounts for any di.erences in installation of these components.

Subpart F : Equipment
(d) A means mustbeidenti.ed orprovidedfordetermining theformation ofice onthe criticalparts of the airplane.Adequatelighting mustbeprovidedfor the use of this meansduring night operation.Also, when monitoring ofthe external surfaces of the airplaneby the .ight crewisrequiredforoperationof theiceprotectionequipment, external lighting must be provided that is adequate to enable the monitoring to be done at night. Any illumination that is used must be of a type that will not cause glare or re.ection that would handicap crewmembers in the performance of their duties. The Airplane Flight Manual or other approved manual material must describe the means of determining ice formation and must contain information for the safe operation of the airplane in icing conditions.]

33.6 Miscellaneous Equipment
FAR 23.1431 : Electronic equipment.
(a)
In showing compliance with Sec. 23.1309(b)(1) and (2) with respect to radio and electronic equipment and theirinstallations, critical environmental conditions must be considered.

(b)
Radio and electronic equipment, controls, and wiring must be installed so that ope-ration of any unit or system of units will not adversely a.ect the simultaneous operation of any other radio or electronic unit, or system of units, required by this chapter.

(c)
[For those airplanes required to have more than one .ightcrew member, or whose operation will require more than one .ightcrew member, the cockpit must be eva-luated to determine if the .ightcrew members, when seated at their duty station, can converse without di.culty under the actual cockpit noise conditions when the airplane is being operated. If the airplane design includes provision for the use of communication headsets, the evaluation must also consider conditions where headsets are being used. If the evaluation shows conditions under which it will be di.cult to converse, an intercommunication system must be provided.
