This is a general curriculum that has been developed to identify the minimum knowledge and skill requirements of a composite and/or metal bond repair technician/specialist. This revision changes the document from an all-inclusive curriculum into a modular set of curricula. Teaching levels have been assigned to the curriculum to define the knowledge, skills and abilities graduates will need to make composite repairs. Minimum hours of instruction have been provided to ensure adequate coverage of all subject matter - lecture and laboratory. These minimums may be exceeded, and may include an increase in the total number of training hours and/or increases in the teaching levels.
This SAE Aerospace Standard (AS) specifies the interface requirements for tow bar attachment fittings on the nose gear (when towing operations are performed from the nose gear) of conventional tricycle type landing gears of commercial civil transport aircraft with a maximum ramp weight higher than 50 000 kg (110 000 lb), commonly designated as "main line aircraft". Its purpose is to achieve tow bar attachment fittings interface standardization by aircraft weight category (which determines tow bar forces) in order to ensure that one single type of tow bar with a standard connection can be used for all aircraft types within or near that weight category, so as to assist operators and airport handling companies in reducing the number of different tow bar types used.
This SAE Aerospace Recommended Practice (ARP) outlines the basic general design considerations for transport aircraft tow bars. It does not cover the requirements for tow bars intended for aircraft with a maximum ramp mass (MRW) below 8600 kg (19 000 lb).
The purpose of this SAE Aerospace Information Report (AIR) is to provide information that would be useful to potential users/operators and decision makers for evaluating and quantifying the benefits of an Engine Monitoring Systems (EMS) versus its cost of implementation. This document presents excerpts from reports developed to analyze "actual aircraft cost/benefits results". These are presented as follows: a. First, to outline the benefits and cost elements pertaining to EMS that may be used in performing a cost versus benefits analysis. b. Second, to present considerations for use in conducting the analysis. c. Third, to provide examples of analyses and results as they relate to the user/operator and decision-maker community. The document encompasses helicopters and fixed wing aircraft and distinguishes between civilian and military considerations.
Minimum Performance Requirements for Non-Refrigerant Tracer Gasses and Electronic Tracer Gas Leak Detectors
This standard provides the testing and functional requirements guidance necessary for a leak detection device that uses any non-A/C refrigerant tracer gas, such as helium or a nitrogen-hydrogen blend, to provide functional performance equivalent to a refrigerant electronic leak detector. It explains how a non- refrigerant leak detector’s calibration can be established to provide levels of detection equal to electronic leak detectors that meet SAE J2791 for R-134a and SAE J2913 for R-1234yf.
This SAE Aerospace Recommended Practice (ARP) covers the requirements for a Stationary Runway Weather Information System (referred to as the systemRWIS or System) to monitor the surface conditions of airfield operational areas to ensure saferthe conditions of the aircraft ground operations of aircraft areas of an airport. The RWIS shall providesystem provides (1) temperature and condition information of runway, taxiway, and ramp pavements and (2) provide atmospheric weather information conditions that assist needed airport personnel to maintain safer and more for efficient airport operations and maintenance. The system can be either a wired system or a wireless system.
This paper describes a recommended practice and procedure for the correlation of test cells that are used for the performance testing of turboprop and turboshaft engines. This Aerospace Recommended Practice (ARP) shall apply to both dynamometer and propeller based testing. Test cell correlation is performed to determine the effect of any given test cell enclosure and equipment on the performance of an engine relative to the baseline performance of that engine.
The configuration of a test facility that exists at the time when a correlation is being carried out should be "base lined" as a condition of correlation approval acceptance, and, be maintained during the time period that the respective correlation approval lasts. This defines test facility configuration control. This is due to the fact that a change in configuration may have the potential to change the established correlation factors and measured engine performance. If such a change occurs then this should be judged by the respective OEM's or designated correlation approval authorities Subject Matter Expert (SME). In some cases, this may involve consultation with the engine project customer or airworthiness authorities.
Aerospace Qualified Electronic Component (AQEC) Requirements, Volume 1 - Integrated Circuits and Semiconductors
This Standard applies to integrated circuits and semiconductors exhibiting the following attributes: a. A minimum set of requirements, or information provided by the part manufacturer, which will allow a standard COTS component to be designated AQEC by the manufacturer. b. As a minimum, each COTS component (designated AQEC) will have been designed, fabricated, assembled, and tested in accordance with the component manufacturer's requirements for standard data book components. c. Qualification of, and quality systems for, the COTS components to be designated as AQEC shall include the manufacturer's standards, operating procedures, and technical specifications. d. Components manufactured before the manufacturer has addressed AQEC requirements, but utilizing the same processes, are also considered AQEC compliant. e. Additional desired attributes of a device designated AQEC (that will support AQEC users) are found in Appendix B of this standard.
Drivers who live where it gets really cold in the winter know the value of remote-starting systems. In this episode of SAE Eye on Engineering, Senior Editor Lindsay Brooke looks at remote-starting technology.
Pallet extensions provide support for items of cargo beyond either the short or the long sides of a pallet, allowing increased volume to be achieved. The extensions are desgtned to suit the contour of wide-bodied aircraft. Each extension consists of a panel or shelf extending upwards and outboards within an envelope bounded by the ULD contour (see Figures 1, 2, 3, and 4). The panel or shelf is secured in this position by means of chains, cables, or structural members attached to the rails of the adjacent sides of the pallent edge.

This document applies to the development of Plans for integrating and managing electronic components in equipment for the military and commercial aerospace markets; as well as other ADHP markets that wish to use this document. Examples of electronic components, as described in this document, include resistors, capacitors, diodes, integrated circuits, hybrids, application specific integrated circuits, wound components, and relays. It is critical for the Plan owner to review and understand the design, materials, configuration control, and qualification methods of all "as-received" electronic components, and their capabilities with respect to the application; identify risks, and where necessary, take additional action to mitigate the risks. The technical requirements are in Clause 3 of this standard, and the administrative requirements are in Clause 4.
