New Guide for In-Time Aviation Safety Management System (IASMS) Functionality
1. Scope
1.1 This ‘Standard Guide’ is intended primarily for industry: UAS designers, integrators, and service providers who wish to increase awareness of potential approaches that are suitable for In-Time Aviation Safety Management System (IASMS) functionality, to aid system design, implementation, evaluation, and operation. IASMS functionality will be referred throughout this standard guide, for convenience, as In-Time Aviation Safety Management (“IASM”).
1.2 Per the guidance in Form and Style for ASTM Standards, this standard guide should not be used directly as a specification for a capability, system, service, or function for an IASMS. This standard guide serves as a reference to develop a specification for an IASM capability, system, service, or a function. Additionally, this standard guide can be used as a reference for how one or more of these elements could be developed or augmented with IASM.
1.3 This standard guide is structured such that IASM functions, focusing on the IASMS approach, including monitoring, assessment, and mitigation. Additionally, IASM functions include data exchange as a supporting but essential fourth component of the approach. These functions are detailed in individual sections.
1.4 Not every type of UAS operation, including its user(s), the environment, associated elements (“AE”), and the UAS itself, is discussed comprehensively in this standard guide. Rather, a representative range of approaches for IASM functionality is provided.

Rationale
This standard guide is needed because existing standards and associated guidance do not address fault and failure modes that are crosscutting in terms of the UAS, services, systems, operator, and the environment. Additionally, there is no standard that provides potential approaches for how to monitor or alert in response to the presence of such fault and failure modes, how to assess their impact on flight and supporting capabilities (such as navigation) and risk, and how to approach mitigating them during flight operations. Existing standards’ individual requirements for functions like monitoring and alerting may share names with IASM functions, however these standards do not sufficiently address integration-level failure modes identified in this guide.
The intended users and usage of this standard guide is summarized in 1.1.
