DCS World Training Mission: Texas Helo Range (1/3)

As a follow-up to the previous training scenario centered on Tarnak Range for fixed-wing aircraft, this mission shifts focus toward rotary-wing operations. To avoid any jealousy from our “slow-mover” friends, this post introduces Texas Helo Range, a lesser-known but operationally significant training area used primarily by helicopter crews deployed out of Kandahar Airfield.

Often overlooked in official charts and sparsely documented, Texas Helo Range was known primarily to those who flew rotary-wing missions in the region, and its recreation in DCS offers a nice opportunity for helicopter pilots to train with appropriate terrain considerations and realistic procedures in a combat-relevant environment.

Texas Helo Range: General Layout and Purpose

Texas Helo Range was a designated rotary-wing gunnery range situated in southern Afghanistan, approximately 9 nautical miles south of Kandahar Airfield. The range extended in a rectangular shape area to the south, reaching about 12 nautical miles south of the field. Geographically, it was located at the northeastern edge of the Registan Desert, an earea of sparsely populated, arid terrain known as the “Red Desert.” Its isolation and predictable visibility conditions made it ideally suited for air-to-ground training by coalition rotary-wing assets.

The range was purpose-built to support helicopter-mounted machine gun training, with a specific focus on general-purpose machine guns (GPMG) used in door-mounted roles. The site was structured around fixed gun lanes, each clearly demarcated with physical and procedural boundaries, to facilitate controlled, repeatable weapons employment. These lanes were designed to manage firing arcs, ensure aircraft separation, and control weapon trajectories. The physical configuration of the range emphasized safety through both design and oversight, ensuring that all munition trajectories remained well within designated safety arcs.

The Registan Desert, often referred to as the "Red Desert", is a defining geographical feature of southeastern Afghanistan. Texas Helo Range is encompassing the isolated mountains at the center of this picture.

Training activities on Texas Helo Range included both dry and live-fire exercises, allowing aircrews to rehearse engagement profiles under realistic conditions. These included approaches, acquisition, and engagement from both left and right-hand gunner positions, often coordinated between lead and wingman aircraft. The gun runs were flown with precision, adhering to fixed ingress and egress headings, and often conducted in profile pairs or formation to simulate combat team tactics.

During periods of live-fire activity, the range was actively monitored and controlled. A Liaison Officer (LNO) or a designated Range Safety Officer (RSO) was typically positioned in Kandahar control tower, overseeing operations. The RSO was responsible for maintaining safety standards, providing clearance for firing runs, and ensuring immediate coordination in case of emergencies or misfires. Crews were required to check in with range control before commencing activity and remained under procedural control throughout their training window.

The range was used extensively all coalition rotary-wing platforms. It played a critical role in gunnery qualifications, mission rehearsals, and operational validation. The environment fostered operational realism, particularly in preparation for close support or overwatch roles in the Afghan theater. Standard operations included the use of specific target sets placed within the firing lanes, often visualized by dust trails, terrain contrast, or temporary ground markers.

Exactly as for Tarnak Range, Texas Helo Range’s significance extended beyond weapons training. It served as a venue for reinforcing cockpit coordination, pilot-gunner communication, range safety protocol adherence, and procedural discipline. These were foundational skills for aircrew deployed in combat zones where weapon handling, target identification, and engagement discipline had to become second nature.

Crash of Lynx ZF540 at Texas Helo Range

While this training range provided a realistic and valuable training environment for helicopter crews operating out of Kandahar, its demanding terrain and low-level profiles were not without risk. You'll find here the example of a tragic incident that underscores the challenges of rotary-wing gunnery training in this austere environment.

On 20 December 2013, a British Army Air Corps Lynx Mk9A helicopter, serial number ZF540, was involved in a fatal accident at Texas Helo Range in southern Afghanistan. The aircraft was participating in a training mission involved a formation of two Lynx helicopters practicing live firing with the M621 20mm cannon mounted on the rear left cabin position. As part of the exercise, both helicopters conducted repeated firing runs onto designated range targets.

While preparing for another attack pass, ZF540 entered a tight right-hand orbit at low altitude, likely to reposition for a firing run. During this maneuver, the aircraft experienced a sudden loss of lift, leading to a rapid and unrecoverable descent. The helicopter struck the ground in a steep right-hand bank and with near-vertical attitude. Tragically, all five personnel on board were killed on impact. The second Lynx in the formation witnessed the crash and immediately reported the incident.

The subsequent inquiry (all info available here) identified the most probable cause as a loss of lift during a low-speed, low-altitude turn. The helicopter was operating close to the limits of its aerodynamic performance in an environment with minimal room for error. The maneuver likely led to a combination of insufficient airspeed and an excessive bank angle, both of which reduced lift below the level required to sustain flight. Environmental conditions, including dust and terrain features in the range area, may have further complicated the pilot’s ability to perceive height and depth, impairing situational awareness at a critical moment.

Workload in the cockpit was assessed as a significant contributing factor. The training setup placed high demands on both the flying pilot and the rear gunner. The coordination required for targeting, communication, and aircraft control during live-fire exercises is complex and time-sensitive. In this case, it may have diverted attention from key flight parameters during the maneuver that preceded the crash.

While low-level live-fire exercises are often perceived as "fun", it is important to remain constantly aware of the heightened risks inherent to these demanding maneuvers.

The official report produced a number of recommendations. The most important of them was the reinforcement of altitude discipline during dynamic maneuvers, especially in environments where visual cues may be limited or degraded. The inquiry also stressed the need for conservative turn parameters when operating near the ground, and highlighted the importance of robust crew coordination and clearly defined roles between the pilot and gunner. Recommendations also included enhancements to simulator training to better replicate the risks associated with low-speed, low-level flight in operational settings.

The absence of distinct visual references, combined with blowing dust, can rapidly turn the desert into a "degraded visual environment" (or DVE), severely limiting situational awareness.

In the context of DCS, while the physical consequences of a mishandled approach are virtual, the training value is real. Pilots simulating helicopter gunnery missions should maintain a strict safety buffer from the terrain and be particularly cautious when conducting attack patterns that involve steep turns or significant altitude changes. Familiarity with terrain, careful planning and briefing, and precise coordination with simulated or multiplayer crew members are important for building and reinforcing safe operating habits. The lessons from this incident remain highly relevant for any aviator, real or virtual, who seeks to operate helicopters effectively in a tactical environment...
