AIR1207
Today's sophisticated aircraft are required to effectively perform a variety of missions. With the advent of micro-miniaturization in electronics and advanced digital computers, a new generation of avionics equipment and systems can be utilized to increase the capabilities of the aircraft. As the quantity and variety of equipment and functions increases, the problems of inter-connecting these equipments with wires presents a constraint on size, weight, signal conditioning, reliability, maintainability and electromagnetic control. Conventional wiring has resulted in large bundles of wires and many connectors which adds excessive weight and reduces the space available for the pilot and other vital elements. This limitation can be relieved significantly by the application of well proven multiplexing techniques.

The standard delineates the characteristics of electric power supplied to airborne equipment at the equipment terminals and the requirements for the utilization of such electric power by the airborne equipment. The purpose of this standard is to foster compatibility between aircraft electric systems or ground support electric systems and airborne utilization equipment to the extent of confining the aircraft and ground support electric power characteristics within definitive limits and restricting the requirements imposed on the power by the airborne utilization equipment.

ARP1061
This ARP provides performance criteria for Altitude Alerting Devices and Systems. These devices can be self-contained or receive remote altitude information and can have integral or remote barometric corrections. Only the generation of the laerting signals is covered by this recommended practice and not the details of the visual or audio alerts operated by these signals. It is recommended that the system's operational correspondence between the selected altitude settings of the Altitude Alerting Device and the Altitude Level Indication normally used to control the aircraft should not exceed ±250 ft RSS throughout the operating range of the device.

This checklist is to be used by project personnel to assure that factors required for adequate system electromagnetic compatibility are considered and incorporated into a program. It provides a ready reference of EMC management and documentation requirements for a particular program from preproposal thru acquisition. When considered with individual equipments comprising the system and the electromagnetic operational environment in which the system will operate, the checklist will aid in the preparation of an EMC analysis. The analysis will facilitate the development of system- dependent EMC criteria and detailed system, subsystem, and equipment design requirements ensuring electromagnetic compatibility. It should be noted that all subjects are not covered and that all items listed may not be required on a given program.

J994A_197110
The scope of this SAE Standard is the definition of the functional, environmental, and life cycle test requirements for electrically operated backup alarm devices primarily intended for use on off-road, self propelled work machines as defined by SAE J1116 (limited to categories of 1) construction, and 2) general purpose industrial). This purpose of this document is to define a set of performance requirements for backup alarms, independent of machine usage. The laboratory tests defined in this document are intended to provide a uniform and repeatable means of verifying whether or nor a test alarm meets the stated requirements. For on-machine requirements and test procedures, refer to SAE J 1446.

AIR1255
This AIR was prepared to inform the aerospace industry about the electromagnetic interference measurement capability of spectrum analyzers. The spectrum analyzers considered are of the wide dispersion type which are electronically tuned over an octave or wider frequency range. The reason for limiting the AIR to this type of spectrum analyzer is that several manufacturers produce them as general-purpose instruments, and their use for EMI measurement will give significant time and cost savings. The objective of the AIR is to give a description of the spectrum analyzers, consider the analyzer parameters, and describe how the analyzers are usable for collection of EMI data. The operator of a spectrum analyzer should be thoroughly familiar with the analyzer and the technical concepts reviewed in the AIR before performing EMI measurements.

The purpose of this document is to set forth the recommendations of SAE Committee S-7 relative to the location and actuation of flight deck controls. These recommendations are intended to minimize confusion and distraction and thereby reduce transition training time, crew errors, fatigue, and other factors detrimental to flight safety and efficiency. In arriving at these recommendations, the committee carefully reviewed the work of the flight deck layout panel of the Aircraft Committee of the Munitions Board, the recommendations and requirements of the Civil Aeronautics Board, the Federal Aviation Agency, the requirements of the airline operators, the aircraft manufacturers, etc. In cases where conflicting opinions existed, suitable compromises were made. The recommendations of this document apply to commercial type, multi-engine transport aircraft which utilize reciprocating or turbine type powerplants and which are operated in subsonic, transonic, or supersonic speed regimes.

Electronic systems must be able to withstand certain radiation environmental stresses which could potentially result in significant transient currents to its semiconductors. The reliability of integrated circuits is dependent upon the overstress to which they are exposed in operation. Overstress of the integrated circuit in the form of metallization burnout causes openings in the interconnection paths leading to failure of the connected circuitry. This study seeks to identify the failure mechanism with its corresponding thresholds and magnitude of currents as well as to identify a probability of survival number for the threshold condition.

An electronic, fully automatic overload indicating system was developed and successfully applied to mobile construction type cranes. A mini-computer monitors the signals from boom load and boom angle transducers. It computes the resultant percentage of rated lifting capacity based on the crane's rating chart. A plug-in program card furnishes the safe operating limits from the rating chart.
