In addition, Hmmsim Legacy supports BVE Trainsim Add-Ons. You can enjoy the same BVE routes you played on PC directly on mobile devices. Expand your experience endlessly with Add-Ons tailored to your preferences.

Red Flag Sim is a modern military aviation simulator built specifically for mobile devices. Mobile platforms have long lacked a combat flight simulator with genuine depth. Red Flag Sim was created to change that, bringing complex flight and avionics systems to mobile through a control scheme designed for touchscreen devices. Our goal is to give players the authentic feeling of operating a fighter aircraft—from trim, angle of attack, energy management, and G-loading to radar, navigation, warning systems, and weapons employment. Every system is modeled around real-world principles and publicly available information. 【IN-DEPTH F-15C SIMULATION】 The current version features the F-15C, demonstrating the level of simulation depth planned for every future aircraft module in Red Flag Sim. Manage the aircraft’s flight state and energy, operate its radar and avionics, employ weapons, navigate, approach, and land safely. This is not an arcade shooter built around simply aiming and firing—it is a flight experience that rewards learning, practice, and continuous improvement. 【REALISTIC FLIGHT DYNAMICS】 Experience how trim, angle of attack, stalls, G-forces, and energy affect the aircraft. Speed, altitude, payload, and control inputs all influence its performance and handling. 【RADAR AND AVIONICS】 Use multifunction displays, fire-control radar, radar warning systems, and navigation equipment to build situational awareness, locate targets, and complete engagements. These systems are designed around meaningful operation and interaction—not merely visual interface effects. 【TRAINING AND QUICK MISSIONS】 Learn essential flying skills, avionics operation, weapons employment, and landing procedures through dedicated F-15C training missions—or jump directly into the cockpit with a selection of quick missions. 【CREATE YOUR OWN MISSIONS】 Use the tactical mission editor to place units, define routes, configure the operating environment, and create your own custom scenarios. 【AN EVOLVING INDEPENDENT PROJECT】 Red Flag Sim has been independently developed by a solo developer and continues to evolve. New terrain, environmental effects, aircraft modules, missions, and simulation systems will be introduced over time. If you have been waiting for a more serious and in-depth combat flight simulator on mobile, welcome to the cockpit of Red Flag Sim. Prepare for takeoff.
