LIQUID ROCKET ENGINE RELIABILITY CERTIFICATION

ARP4900
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.

747 Flight Test Certification

1970-02-01
700828
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 type certification 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.

A Comprehensive Approach to Icing Certification

1975-02-01
750507
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.

A350XWB Icing Certification Overview

2015-06-15
2015-01-2111
The EASA Type Certificate 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.

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.
