This Digital Annex (DA) contains the current, full-PDF version of ARP5149B, Training Program Guidelines for Deicing/Anti-Icing of Aircraft on Ground, as well as .jpeg format files of Appendix D, Application Guidelines Configuration, Critical Component, and Spray Area Diagrams for Aircraft. The .jpeg diagram files may be used by purchasers in accordance with the terms of the included license agreement.

This document establishes the minimum criteria for effective training of air carrier and contractor personnel to deice/anti-ice aircraft to ensure the safe operation of aircraft during ground icing conditions. Appendix D specifies guidelines for particular airplane models.

This document describes the megawatt-level DC charging system requirements for couplers/inlets, cables, cooling, communication and interoperability. The intended application is for commercial vehicles with larger battery packs requiring higher charging rates for moderate dwell time. A simplified analog safety signaling approach is used for connection-detection to guarantee de-energized state for unmated couplers with superimposed high speed data for EVSE-EV charging control and other value added services.

Dynamic impact test represent various automotive collision conditions. The impact testing recommended practice is intended to recognize the capabilities of autonomous vehicles while at the same time recognizing the vehicle fleet into which they are introduced will consist of non-autonomous vehicles for a considerable period of time. The scope of the document is to cover the range of impact conditions expected taking into account the capabilities of the vehicle and the impact testing technology now available for performance evaluation including virtual and physical testing.

Develop and document an aerodynamic constant speed procedure for heavy vehicles that can accurately calculate the aerodynamic performance through the typical expected yaw angles during operation at highway speeds.

The purpose of this AIR is to compile in one definitive source, commonly accepted calibration, acceptance criteria and procedures for simulation of Supercooled Large Droplet (SLD) conditions within icing wind tunnels. Facilities that meet the criteria for either some or all of the recognized conditions will have known SLD icing simulation capability.

This document is intended to serve two purposes: (1) provide a list of topics for potential customers to ask of the facility to aid their selection decision-making, and (2) provide a list of icing wind tunnel and engine test stand facilities that simulate flight through icing or ice crystal clouds.

This AIR addresses the use of Software tools to supplement or automate human activities in the development of systems, but not the hardware or software items within those systems. If a systems development tool is also used in the scope of hardware or software item development, for that usage it would then become subject to the guidance presented in DO-254 and DO-178B/C, respectively.

AS 6413 and slash sheets /1 & /2 hold the main information for testing of battery packaging. This document holds further information and expansion of philosophy, clarification etc. surrounding the testing and industry needs.

This AIR will provide a basic understanding of STPA and how it can be applied to development and safety assessment of civil aircraft. It will explain, by way of an example, the information needed to begin STPA, the expected STPA outputs, and the phases of aircraft development and safety assessment that can be supported by STPA.

Clarify the role of the human considerations in Functional Hazard Assessments by identifying the sufficient input information regarding those considerations from the development process, how failure conditions may use that information, and what information the safety assessment process provides to other processes, particularly Human Factors, to assure those aspects of failure conditions are valid.

This AIR would examine the applicability of ARP 4754 and ARP 4761 to UAS and would identify the shortcomings in both recommended practices with regards to the specific technical aspects needed for UAS development.

This document provides information on current practices for testing air data probes to 14 CFR Part 33 Appendix D ice crystal and mixed phase icing conditions. This AIR is primarily concerned with techniques for measuring the flow and icing environment in the test facility. While the focus of this report is the testing of air data probes, techniques described may be applicable to Appendix D tests of other aerospace equipment as well.

A review of icing materials that would be educational to a designer of a UAV ice protection system is provided. Additionally, the differences between unmanned and manned ice protection systems are explored along with a discussion on how these differences can be addressed.

This standard is intended to demonstrate and document the control of the potential hazards from lithium cells or batteries (UN 3090 and 3480) when transported as cargo on aircraft. [still need to identify if we are addressing global (external fire) or local (battery internal failures)] This standard addresses the need to control the hazards which might arise from a failure from an individual cell by containing the hazards within the package. This specific hazards addressed within this standard are: • Uncontrolled fire • Rapid overpressure pulse within compartment

This category specification provides a minimum performance standard that may be used for mitigation means, in addition to the foundation specification (AS6413), to provide external fire thermal threat capability which supports the safe shipment of lithium batteries as cargo on aircraft. This slash sheet provides information and testing to assist or augment the performance of the packaging used for shipping of lithium batteries. If protective equipment and measures are used, the performance of the battery package under the challenge of external heat and fire may be improved and enhanced.

The new standard will establish minimum performance requirements for angle of attack (AOA) and angle of sideslip (AOS) sensors in ice and rain conditions. The new standard will cover the various sensor technologies used to measure these flow angles and is limited to the sensor itself as defined from the portion of the sensor that is directly exposed to the ice and rain environment to the means by which its output is relayed to the relevant aircraft systems. The user of this standard must evaluate the aircraft level installation requirements for the probe to ensure adequate coverage for the application. It may be necessary to modify the test conditions in order to meet the applicable installation requirements.

This document describes a method for measuring deformations, and fragment distribution patterns during an impact between a soft or frangible projectile and a regular helispherical leading edge. The document describes the hardware, setup, and instrumentation required. In this test method a soft body projectile impacts a helispherical leading edge symmetric to the curvature and centric in the transversal direction. The ductile target is backup by a rigid adapter structure behind. The target must be sufficiently large so that the projectile flows around its curvature and induces an indentation. This test is intended for measuring the remaining plastic deformation of the target after the impact. The projectile breakup pattern data may also be captured during this test. The values stated in either SI units or inch-pound units are considered separate standards. The values stated in each system may not be exactly equivalent; therefore, each system must be considered as independent.

This document describes a method for measuring deformations from a normal impact between a soft or frangible projectile and clamped plate. The document describes the hardware, setup, and instrumentation required. In this test method a soft body projectile impacts a square ductile plate clamped on all four sides. This test is intended for measuring the remaining plastic deformation of the target after the impact.The values stated in either SI units or inch-pound units are considered separate standards. The values stated in each system may not be exactly equivalent; therefore, each system must be considered as independent. This standard does not address all of the safety concerns associated with its use. It is the responsibility of each user of this standard to ensure that any safety issues are properly addressed.
