TL;DR: In this paper, the authors describe the most significant regulatory involvement a developer is likely to encounter in the certification of avionics and discuss certification activities appropriate to the US Federal Aviation Administration (FAA).
Abstract: This chapter describes the most significant regulatory involvement a developer is likely to encounter in the certification of avionics. It discusses certification activities appropriate to the US Federal Aviation Administration (FAA). The chapter discusses some representative differences between FAA practices and those of Europe’s Joint Aviation Authorities. The Federal Aviation Regulations provides several different forms of approval for electronic devices installed aboard civil aircraft. Of these, most readers will be concerned primarily with approvals under the technical standard order system, approvals under a supplemental type certificate (STC), or approvals as part of a type certificate, amended type certificate, or service bulletin. The STC process assumes modification of at least one prototype aircraft. It is in the aircraft modification that all the engineering analysis—aircraft performance, structural and electrical loading, weight and balance, human factors, and so on—comes together. New avionics equipment installed as part of an STC will often lead to new and different procedures for flight crews.

TL;DR: The C-141 as mentioned in this paper was the first airplane to be certified to both military and Federal Aviation Agency (FAA) requirements, with type certification as a requirement of the military contract.
Abstract: For the first time in this country, an airplane has been developed to both military and Federal Aviation Agency (FAA) requirements, with type certification as a requirement of the military contract. Although fundamentally an exploitation of proven state of the art, the 318,000-lb C-141 has many unusual features and represents the solution of several interesting development problems. Of chief interest are its cargo-handling features, the aerodynamic design of its modestly swept wing and of its T-tail, the derivation of its low-drag fuselage afterbody with full cross-section loadable opening, its stringent weight-control program, its long fan-duct nacelle design, its short nacelle inlets, its flight-station innovations for crew efficiency and comfort, and its unique main-landing-gear design. Rather substantial test programs are still in progress, mainly, by now, in the fatigue and flight areas. The C-141 received its FAA type certificate on January 29,1965.

TL;DR: This paper studies the history of cabin pressurization regulations and makes policy recommendations to amend them in a manner that would encourage the design of all-new aircraft.
Abstract: This paper studies the history of cabin pressurization regulations and makes policy recommendations to amend them in a manner that would encourage the design of all-new aircraft. One recently amended regulation (Code of Federal Regulations, Title 14, Sec. 25.841) has an unintended byproduct. The Federal Aviation Administration must grant a compliance waiver in order to certify a new aircraft design with wing-mounted engines to fly at altitudes much above 40,000 ft. However, the Federal Aviation Administration grandfathers existing designs with higher certified ceilings and permits these designs to be modified under the Changed Product Rule (Code of Federal Regulations, Title 14, Sec. 21.101). Because all but the largest commercial aircraft have their useful aerodynamic efficiency compromised if they are restricted to fly at or below 40,000 ft, the current regulation favors current production or derivative changes to existing certified aircraft over the development of an all-new modern airframe.

TL;DR: The systematic approach leading to the award of the Loran-C certification is described, which includes a thorough examination of the certification process, the accuracy requirements described in the Federal Aviation Administration's Advisory Circular 90–45A “Approval of Area Navigation Systems for Use in the U.S. National Aerospace System,” the organization of the program, the preparation of a flight test plan, and the analysis of the data, and resulting conclusions.
Abstract: On October 9, 1981, a Supplemental Type Certificate for airborne, en route, IFR use of Loran-C was awarded to the State of Vermont following completion of a flight test program by the Transportation Systems Center, Research and Special Programs Administration of the U.S. Department of Transportation.
The certification of a Beechcraft E50 aircraft equipped with a Loran-C navigator, is the first ever granted for use of Loran-C in the National Airspace System and culminates a four-year federal-state evaluation program.
This paper describes the systematic approach leading to the award. It includes a thorough examination of the certification process, the accuracy requirements described in the Federal Aviation Administration's Advisory Circular 90–45A “Approval of Area Navigation Systems for Use in the U.S. National Aerospace System,” the organization of the program, the preparation of a flight test plan, the collection of the data base, the analysis of the data, and resulting conclusions.
