ARP1420C
The turbine-engine inlet flow distortion methodology addressed in this document applies only to the effects of inlet total-pressure distortion. Practices employed to quantify these effects are developing and therefore, periodic updates are anticipated. The effects of other forms of distortion on flow stability and performance and of any distortion on aeroelastic stability are not addressed. The guidelines can be used as necessary to create a development method to minimize the risk of inlet/engine compatibility problems. The degree to which guidelines for descriptor use, assessment techniques, and testing outlined in this document are applied to a specific program should be consistent with the expected severity of the compatibility problem. This Aerospace Recommended Practice (ARP) provides guidelines by which gas turbine engine aerodynamic stability and performance, as affected by the quality of the airflow delivered to the engine, can be evaluated consistently.

This standard specifies the characteristics of the SAE Linear Token Passing Bus (LTPB) Interface Unit. The LTPB provides a high reliability, high bandwidth, low latency serial interconnection network suitable for utilization in real time military and commercial applications. Multiple redundant data paths can be implemented to enhance reliability and survivability in those applications which require these attributes. The token passing and data exchange protocols are optimized to provide low latency and fast failure detection and correction. Physical configurations with bus lengths up to 1000 m can be accommodated. This specification defines the following: a. General Description (3.1): An overview of the LTPB protocol. b. Physical Media Interface (3.2): This portion of the standard defines the physical interface to both optical and electrical bus media. c.

AIR6170A
This test method provides stakeholders (runway deicing chemical manufacturers, users, regulators, and airport authorities) with relative ice melting capacity of runway deicing chemicals, by measuring the amount of ice melted as a function of time. Such runway deicing chemicals are often also used on taxiways and other paved areas. This test method does not quantitatively measure the theoretical or extended time ice melting capability of ready-to-use runway deicing/anti-icing chemicals in liquid or solid form.

(1) The Behavior Annex document provides a standard sublanguage extension to allow behavior specifications to be attached to AADL components. The aim of the Behavior Annex is to refine the implicit behavior specifications that are specified by the core of the language. The Behavior Annex targets the following goals: • Describe the internal behavior of component implementations as a state transition system with guards and actions. However, the aim is not to replace software programming languages or to express complex subprogram computations. • Extend the default run-time execution semantics that is specified by the core of the standard, such as thread dispatch protocols. • Provide more precise subprogram calls synchronization protocols for client-server architectures.

AIR5826B
This document provides a review of published methods that have been used to provide estimates of the levels of distortion and/or the concomitant loss of stability pressure ratio that can occur when the recommended full complement of aerodynamic interface plane high-response instrumentation is not used when obtaining inlet data. The methods have been categorized based on the underlying mathematical representation of the aerophysics. Further, the use of maximum value statistics, which has been used to further improve the results where short-duration time records have been employed, is discussed.

On-Board Diagnostic (OBD) regulations require passenger cars, and light and medium duty trucks, to provide a Data Link Connector to support communication of diagnostic information to off-board devices. Legislated diagnostic information is also required to be communicated in a timely fashion to the off-board devices. Many vehicle manufacturers also provide access to enhanced diagnostic information and vehicle systems/subsystems via this connector. Generally, there are two forms of communication methodologies used in current vehicles: a. Open access to communication busses b. Communication busses isolated via a gateway This document provides guidelines for securing communications with any off-board device for vehicles utilizing either methodology.
