Steps to be taken in the damage tolerance analysis are itemized and details of required certification testing are included. The benefits of multiple load path crack arrest structure compared to single load path integral construction are outlined.
This paper provides information on the Airport Certification Program, including the certification/safety inspection procedures and a list of minimum safety standards that will be contained in the Federal Aviation Regulations (FAR).
This was due to the small number of engines tested, especially identical units, and the limited number and type of tests performed on each engine during a typical qualification or certification test program. ...The Liquid Rocket Certification Subcommittee advocates a new approach to rocket engine reliability certification as a result of reviewing current methods to qualify or certify engines. ...Current design and development practices leading to formal liquid rocket engine qualification (USAF) or certification (NASA) will not achieve the specific reliability objectives of future programs. New rocket engine programs are dictating quantified requirements for high reliability in parallel with a cost-constrained procurement environment.
The certification of the Concorde SST has presented a new challenge to the manufacturers and to the certification authorities in the United Kingdom, France, and the United States of America. ...The certification of the Concorde SST has presented a new challenge to the manufacturers and to the certification authorities in the United Kingdom, France, and the United States of America. Apart from the need to ensure, for an advanced type of civil aircraft, a level of airworthiness at the time of entry into service at least as good as current subsonic jets, many new technical and administrative problems have had to be dealt with. ...Apart from the need to ensure, for an advanced type of civil aircraft, a level of airworthiness at the time of entry into service at least as good as current subsonic jets, many new technical and administrative problems have had to be dealt with.
Five test airplanes were used in an intensive test program involving 1443 flight hr and 36-1/4 airplane months, with the last certification flight on December 23, 1969. Full typecertification approval was granted by the FAA on December 30, 1969 after a total of 10-2/3 months of flight testing. ...The 747 flight test certification program was initiated with the first flight of the No. 1 airplane on February 9, 1969. ...These statistics compare very well with the original program estimates, which were based on Boeing's extensive experience with development and certification testing of commercial transport airplanes. The success of this test program was not due to any great advancements in flight test techniques specifically for the 747, but was due to the tried and proven test methods developed during past certification programs at Boeing.
During the certification of an airplane, the chances of encountering icing conditions as defined in the Federal Aviation Regulations (FAR) are so small that the satisfactory performance of an anti-icing system has to be established by methods other than flight tests in FAR icing conditions. ...The methods used within the industry, therefore, vary very widely in type, scope, and accuracy. This paper describes an approach used by Gates Learjet that is simple and inexpensive to be within the reach of any manufacturer, and accurate enough to contribute towards the creation of a standard procedure within the whole industry.
The EASA TypeCertificate for the A350XWB was received the 30th September 2014 after 7 years of development and verification that the design performs as required, with five A350XWB test aircraft accumulating more than 2600 flight test hours and over 600 flights. ...The intent of this paper is to provide a general overview of the main engineering and test activities conducted in order to support A350XWB Ice and Rain Protection Systems certification. Several means of compliance have been used to demonstrate compliance with applicable Certification Basis (CS 25 at Amendment 8 + CS 25.795 at Amendment 9, FAR 25 up to Amendment 129) and Environmental protection requirements. ...Several means of compliance have been used to demonstrate compliance with applicable Certification Basis (CS 25 at Amendment 8 + CS 25.795 at Amendment 9, FAR 25 up to Amendment 129) and Environmental protection requirements.
For this type of testing, EPA has proposed simulating a vehicle following the hybrid vehicle test procedures, including the use of the vehicle cycles and the A to B comparison testing - as required for the full vehicle evaluation option. ...The use of a normalized powertrain cycle provides for a vehicle independent powertrain evaluation, potentially allowing for a powertrain certification to be applied to many vehicles - as is the case in heavy duty engine emissions certification.
A description of the methods of fatigue analysis and tests which were required to obtain Federal Aviation Agency certification under the Transport Category are presented. The overall program of tests is briefly described, with the major discussion devoted to the fatigue evaluation.
In this context, this paper describes the current aircraft emission certification requirements for pollutants as CO, NOx, Smoke and HC, including the limits applicable to each engine thrust levels. ...In this context, this paper describes the current aircraft emission certification requirements for pollutants as CO, NOx, Smoke and HC, including the limits applicable to each engine thrust levels. Certification tendencies (including more stringent emissions standards) being discussed by the international community are also presented.
That experience is invaluable, but alone it may not lend itself to certification conclusions that are rationally based when evaluating the pilot interaction with new or unfamiliar types of flight deck systems. ...That experience is invaluable, but alone it may not lend itself to certification conclusions that are rationally based when evaluating the pilot interaction with new or unfamiliar types of flight deck systems. Test pilots need to know how to recognize when a cockpit systems function is properly conceived and implemented and more importantly how to recognize when the function may contribute to hazardous errors in interpretation.
The course will define the roles and responsibilities of the Aircraft Certification Office (ACO), Manufacturing Inspection District Office (MIDO), Flight Standards District Office (FSDO), and the Aircraft Evaluation Group (AEG). Type and Supplemental TypeCertification (TC and STC) processes, and Change Product Rule for alterations and modifications to previously type certified aircraft will be discussed.
This four hour short course will provide an overview of the airworthiness certification process and the role of the FAA Designated Engineering Representative (DER) and Authorized Representative (AR) with insight into the type design, minor/ major Changes, FAA conformity process, and test witnessing.
This course describes the basic elements of the process for achieving a successful aircraft certification globally once certification by the State of Design has been accomplished. The regulatory framework established under ICAO is presented with discussion of how major countries around the world comply with the ICAO Standards and Recommended Practices (SARPs).
