How Simulation Addresses Army Aviation Collective Training Challenges

The modern battlefield demands highly synchronised and proficient Army aviation units. Collective training – the practice of multiple units working together to achieve a common mission objective – is important for ensuring tactical readiness. As armies across the world continue to development Live-Virtual-Constructive training environments, the reliance on aviation simulators and simulations will take on more importance in the overall aviation collective training mission. This shift requires a solid understanding of training needs and how current and future simulation capabilities can meet them. Refinement of requirements for simulation and simulator capabilities and their effective utilisation are important for maximising readiness.

The U.S. Army Research Institute (ARI) undertook a critical piece of research with one primary objective: to identify Army aviation collective training challenges and to compare those needs to current (and planned) collective simulation capabilities. The goal was to provide a comprehensive assessment of training challenges, simulation capabilities, and simulation utilisation to identify how best to align training challenges and simulation capabilities while simultaneously increasing simulation utilisation with respect to tactical unit-level training. By understanding the gaps among collective training challenges, simulation capabilities, and simulation utilisation, the findings can directly inform future simulation development and guide training program design.

Unpacking the Research Process

To achieve its objectives, the ARI employed a systematic, multi-step process. This involved identifying the challenges, evaluating current and planned capabilities and utilisation of relevant simulators and simulations, and then analysing these challenges in light of the identified capabilities and utilisation.

Step 1 - Identifying Critical Collective Training Challenges

The initial phase of the research focused on comprehensively identifying the specific training challenges faced by Army aviation units. This step involved conducting focus groups with Subject Matter Experts (SMEs). These SMEs were typically aviation unit leaders, instructor pilots, and senior aviators drawn from Combat Aviation Brigades. Their real-world experience provided insights into the daily complexities and pain points of collective training currently.

Emergent themes from these focus group discussions were collected and then used to develop a set of challenges. To validate and prioritise these, questionnaires were developed based on these themes. These questionnaires were then delivered to a second, larger sample of stakeholders. Participants in this broader survey included a diverse group of Army aviators, simulation experts, and engineers, ensuring a broad perspective on the identified challenges. This process helped collect a wide range of observations into a prioritised list of critical training needs.

Step 2 - Evaluating Simulation Capabilities and Utilisation

The second step in the research involved a detailed evaluation of the capabilities and current utilisation of Army aviation collective simulators and simulations. This phase was needed to understand what resources were available and how effectively they were being employed in training.

To gather this information, researchers conducted interviews with technical experts. These experts provided insights into the design, functionality, and potential of various simulation systems. In parallel, questionnaires were sent to Army aviation collective training and simulation experts. This two-pronged approach ensured that both the technical specifications of the simulation assets and their practical application in collective training environments were thoroughly documented. The data collected in this step formed the baseline against which training challenges could be compared.

Step 3 - Analysing Challenges Against Capabilities and Utilisation

The final step involved an analysis of the identified critical challenges with respect to the documented simulation capabilities and their utilisation. This analysis was structured into four sub-steps:

1. Assessing Challenge Importance - Reaffirming the criticality and frequency of the identified training challenges.

2. Resource Availability - Determining which resources were relevant and available to address each challenge.

3. Assessing Capability and Utilisation - Evaluating whether the available resources possessed the necessary fidelity and features to effectively address the challenge, and whether they were actually being used to their full potential for that purpose.

4. Drawing Conclusions - Formulating insights and findings based on the comparisons.

To ensure the validity and practical relevance of the findings, the conclusions drawn from this analysis were then presented to and validated with a group of experienced simulation and training experts in a dedicated workshop.

Key Challenges Identified by the Research

The process of focus groups and questionnaires successfully identified a series of collective training challenges faced by Army aviation units. Based on frequency of mention and perceived importance, 16 top themes were included in subsequent questionnaires. These were further refined into 17 collective challenges, each with clear operational definitions, ensuring consistency in understanding across the board.

Four of the six highest-ranked collective challenges were found to be universally relevant across all 18 relevant Army aviation Mission Essential Task Lists (METLs). These pervasive challenges included:

• AMC and PC Development - The advancement of Aircraft Commander (AMC) and Pilot-in-Command (PC) skills.

• Battlefield Communications - Effective communication in complex operational environments.

• Preparing New Pilots - Integrating and developing less experienced aviators into collective exercises.

• Mixed Airframe Missions - Coordinating operations involving different types of aircraft within a single mission.

Beyond these top four, "Air to Ground Integration" was relevant to 15 METLs, indicating its widespread importance, and "ROE (Rules of Engagement) Processes and Procedures" also consistently ranked as highly relevant.

Examples of Key Challenges

To provide a clearer picture of these challenges, the research elaborated on some examples:

Battlefield Communications

This challenge was precisely defined as "communicating the right information to the right person on the right frequency/communication system at the right time". In complex, dynamic battlefields, effective and timely communication is required for mission success and safety. This challenge highlights the need for training environments that accurately replicate the complexities of communication networks, including potential disruptions, multiple channels, and the pressure of real-time information exchange.

Preparing New Pilots

This challenge requires a focused effort on inserting and accomplishing specific developmental training objectives for new pilots into collective exercises. It's not enough for new pilots to simply participate; units must actively analyse the needs of less experienced aviators and purposefully incorporate these developmental objectives into collective training events. Components of addressing this challenge include thorough evaluation and targeted feedback for new pilots. The research concluded that effectively preparing new pilots in a collective setting requires replicating the operational environment and cockpit realistically within simulation, and emphasising that company commanders should focus on developing clear training plans and evaluation criteria for these individuals.

ROE Processes and Procedures

This challenge was defined as "understanding what rules of engagement are and how they impact decision making". In modern combat, ROE are complex and their correct application is important for mission effectiveness and avoiding unintended consequences. Key themes related to this challenge included the recognition that semi-automated forces in simulations could be deliberately ambiguous, much like real combat situations, thus requiring pilots to actively apply decision-making strategies related to ROE. Furthermore, the availability of a "white cell" (personnel who control the exercise flow and introduce events) was noted as valuable for creating specific ROE-related training conditions. A renewed focus on developing precise training plans and company-level objectives related to ROE before exercises would significantly improve training opportunities in this area.

Simulation Capabilities and Training Gaps Army Aviation

A core component of the ARI research involved not only documenting the capabilities and capacities of Army aviation collective simulators and simulations but also illustrating the crucial concept of gaps in training provision. This framework helps show exactly where resources are falling short or are under-utilised.

The concept of gaps is typically illustrated with three overlapping circles:

• Collective Training Challenges (blue circle) - This represents the broad set of training needs and requirements that Army aviation units face.

• Collective Simulation-Training Capability (yellow circle) - This is what existing simulation capabilities and resources can address within the training challenges.

• Collective Simulation-Training Utilisation (green circle) - This represents the subset of capabilities that are actually utilised in collective training events.

Understanding these distinctions allows for precise identification of gaps:

• Gaps in simulation capability - These are defined as the difference between the yellow and blue circles. This signifies training challenges that current simulation capabilities cannot address due to technical or design limitations.

• Gaps in simulation utilisation - These are the difference between the green and yellow circles. This represents the potential for increasing the use of existing capabilities that are currently under-utilised in collective training.

The analysis conducted by ARI found that many capability gaps and many utilisation gaps exist across Army aviation collective training. Findings for challenges like Battlefield Communications and ROE Processes and Procedures explained which resources were found relevant, which lacked the necessary capability (e.g., Evaluator Training lacked capability for both of these ), and which were under-utilised (often due to factors like cost or not being requested by units). Identifying these gaps is the first step towards effectively bridging them.

Fidelity Considerations in Military Flight Simulation

The effectiveness of simulation, particularly in addressing complex collective training challenges, often rests on the concept of fidelity. Fidelity refers to the degree to which a simulator accurately replicates the real-world environment and aircraft behaviour. For military aviation, fidelity requirements can differ significantly from civil aviation.

For example, the Military Aviation Authority of the Netherlands has been developing a tailored system for military flight simulator qualification. A new approach, distinct from civil aviation standards, was needed to adequately address the unique requirements of typical military tasks.

The aim for military simulators is to achieve maximum flexibility in using both existing and future simulation systems. A task-oriented approach allows for maximising the benefit derived from simulators and fully exploiting their capabilities for specific training objectives. This approach also enables more cost-effective upgrades to simulators, as improvements can be directly weighed against their potential to reduce expensive live flight hours.

Key fidelity considerations for military flight simulators include:

• Control Forces and Dynamics - How accurately the feel and response of aircraft controls are replicated.

• Vision Systems - Aspects such as resolution, light levels, and Field of View (FOV) are crucial for visual realism. Military operations, in particular, often require extended FOVs that go beyond typical civil regulations. The research noted that separating FOV from resolution and brightness metrics was appropriate for military classification, acknowledging these distinct operational needs.

• Motion Simulation - The ability of the simulator's motion base to accurately provide motion cues to the pilot.

Crucially, minimum fidelity levels should be set to ensure that they do not cause negative training transfer, meaning the simulator should allow tasks to be executed substantially similarly to how they would be performed in the real aircraft. It's also recognised that certain tasks might be perfectly doable with systems of limited fidelity (e.g., tasks primarily performed on autopilot). Studies suggest that a substantial portion, up to 50%, of aviation training can be effectively conducted on Flight Simulation Training Devices (FSTDs) even without extremely high fidelity, provided they are above a certain minimum acceptable level. However, the research also highlights that more studies are needed to precisely define these minimum fidelity requirements for FSTDs across various military training tasks.

A Path to Enhanced Readiness?

The ARI research identified several overarching themes regarding Army aviation collective training and proposed tangible recommendations for various stakeholders.

Key Themes Identified

One central theme was the intense focus on simulation-training resources for Army aviation collective training. Despite this, it was also clear that the unit itself bears the primary responsibility for identifying specific training needs and building comprehensive collective training plans. A persistent challenge identified was that commanders may not always fully recognise or embrace their critical role in the detailed planning and execution of simulation-based training. Consequently, simulation experts must ensure that tactical leaders are fully aware of the available tools and how to best make use of them. Effective prioritisation and clear communication of collective training objectives are key inputs to success.

Recommendations for Training Developers and Facilitators

For those involved in developing training programs and facilitating collective training exercises, the research offered specific recommendations:

• Use realistic settings and configurations for communication tools within simulations. This directly addresses the Battlefield Communications challenge.

• Develop and apply standardised evaluation metrics, then provide targeted feedback to units and individuals. This ensures consistent assessment and actionable insights.

• Develop "take-home packages" summarising areas for focus and improvement after exercises. This reinforces learning beyond the simulator session.

• Work proactively with units to incorporate company-level objectives into larger exercises. This helps ensure the training is tailored to specific unit needs.

• Develop and implement Unmanned Aircraft System (UAS) technology appropriately within simulation, reflecting its growing role in modern operations.

Recommendations for Unit Leaders and Trainers

For the unit leaders and trainers on the ground, the research provided this guidance:

• Develop training plans and conduct METL crosswalks before exercises. This proactive planning ensures training directly supports mission essential tasks.

• Ensure company-level objectives are clearly communicated to exercise coordinators well in advance. This allows for better integration into the overall exercise design.

• Communicate unit-level objectives related to the area of operations to training developers. This provides necessary context for realistic scenario creation.

• Bring experienced aviators and leaders to evaluate flight teams during collective exercises. Their expertise is invaluable for real-time assessment and feedback.

• Utilise or bring suitable Defence legal personnel if ROE is a primary training focus. This ensures legal and ethical considerations are accurately addressed.

• Incorporate unit-level objectives into the overall Brigade training plan, ensuring alignment across the command.

Increasing Simulation Utilisation

A overarching general recommendation from the research highlights a pressing need: to significantly increase simulation-training resource utilisation to enhance overall unit readiness. A promising way to achieve this, as suggested by the research, is through the development of a planning aid. This aid would be based on the research's analysis tool, designed to identify simulation resources that precisely match specific METL requirements, inform the best utilisation strategies for those resources, and actively help in planning effective training events. Such a tool could be invaluable for both home-station training and for coordinating larger, more complex events.

Closing the Gap for Enhanced Army Aviation Readiness

This comprehensive research conducted by the U.S. Army Research Institute has provided insights into Army aviation collective training challenges and the important role simulation can play in overcoming them. The research results, including the concept of the analysis tool, were formally briefed to the U.S. Army Aviation Center of Excellence Directorate of Simulation, which actively supported the idea of developing such a simulation-training planning tool.

The end product of this valuable research was indeed the analysis tool: a decision-support matrix designed to improve both the development and the effective use of simulators and simulations for achieving Army aviation collective training objectives. This powerful tool helps unit leaders and specialists enhance their current training programs, while also assisting simulation experts in identifying areas for future improvement and development. The tool is planned for dissemination, ensuring its benefits reach a broad audience across Army aviation.

The insights and learnings from the research undertaken is valuable to Army Aviation units across the world as they plan for future simulation aided collective training into the future.
