This article presents a review about Beyond Visual Line Of Sight (BVLOS) operations using unmanned aircraft in forest environments. Forest environments present unique challenges for unmanned aircraft operations due to the presence of trees as obstacles, hilly terrain, and remote areas. BVLOS operations help overcome some of these unique challenges; however, these are not widespread due to a number of technical, operational, and regulatory considerations. To help progress the application of BVLOS unmanned aircraft operations in forest environments, this article reviews the latest literature, practices, and regulations, as well as incorporates the practical experience of the authors. The unique characteristics of the operating environment are addressed alongside a clear argument as to how BVLOS operations can help overcome key challenges. The international regulatory environment is appraised with regard to BVLOS operations, highlighting differences between countries, despite commonalities in the considerations that they take into account. After addressing these points, technological, operational, and other considerations are presented and may be taken into account when taking a risk-based approach to BVLOS operations, with gaps for future research to address clearly highlighted. In totality, this article provides a practical understanding of how BVLOS unmanned aircraft operations can be done in forest environments, as well as provides a basis for future research into the topic area.

Purpose: This paper aims to critically evaluate the definition of the brand concept, support the critique with an empirical study and provide a definition to resolve the problems that have been identified. Design/methodology/approach: This paper combines a conceptual critique with empirical research using a sample of 730 journal papers to analyse the scope and number of brand-related concepts in extant literature. Findings: The brand concept has evolved to become problematic with no clarity of definition. There has been an explosion in the number of brand-related concepts that make the brand concept opaque and unwieldy. Based upon the findings, the authors argue that it is necessary to return to a “label and associations model” of the brand concept to ameliorate these issues. Research limitations/implications: The empirical research presented examines only 730 papers from a much wider body of brand literature. Nonetheless, it illustrates the fact that researchers and theorists are not talking about the same concept when using the term “brand”. Practical implications: Practitioners are not being served by academic branding literature because no two researchers appear to be studying the same entity. This prevents a body of research from being built to guide practitioners. Originality/value: This paper makes an original contribution by combining a conceptual critique and empirical study to examine the problems arising from the absence of an agreed definition of the brand concept and uses this as a foundation for creating a resolution to the problems.

While the potential risks of unmanned aircraft have received significant attention, there is little in the academic literature that examines how operational risks are mitigated by users. This study examines the prevalence of key operational risk mitigations amongst a sample of 812 unmanned aircraft users in New Zealand, their confidence levels in identifying and complying with airspace requirements, and their ability to read visual navigation charts (VNCs) and use AirShare (a local tool that shows airspace requirements). Significant differences exist between the number and type of mitigations applied, users’ confidence levels in identifying and complying with airspace requirements, and users’ ability to read VNCs and use AirShare based upon user characteristics. Education, practical assessment, membership of a professional body, professional/semi-professional use, and operating for a certificated organisation all improve risk mitigation (greater number and variety of risk mitigations applied). The only risk mitigation employed by almost all users was conducting a pre-flight check of their aircraft, identifying the need for users to view risk mitigation more holistically. The findings support policy directions related to educational requirements, the ability for member-based organisations and professional bodies to self-regulate, and the fitness of the current regulatory system in New Zealand.
