SATCE Solution

Military Pilot Training System


Government defense contractor


ASTi is integrating its Simulated Environment for Realistic ATC (SERA) product into a pilot training system for a major government defense contractor. SERA is ASTi’s response to the International Civil Aviation Organization’s (ICAO’s) recommendation that flight simulators provide a Simulated Air Traffic Control Environment (SATCE) system. SERA provides this full flight military simulator with an immersive air traffic control (ATC) environment and voice interactions with controllers, ground crew, and other entities.

Unique Entities and Voices

Provide a SATCE solution with distinct speech from ATC and pilots on other aircraft.

During a training scenario, the customer’s communication environment is sterile: only students and instructors talk on the airways. To increase realism, the program needs a rich radio environment that generates unique voices for every entity.

SERA creates dozens of different entities in the simulated world, from various ATC to commercial aircraft flying around the airspace. Each entity sounds like a different person, supplying contextually accurate chatter to the environment.

Nonintrusive Dialogue Prompts

Provide a developed speech technology that seamlessly understands and responds to students without getting stuck.

Many SATCE solutions suffer from faulty speech recognition. During flights, they get stuck in error loops that constantly prompt the student to repeat his or her response. Instead of a training enhancement, the technology becomes a frustrating distraction.

ASTi provides top-notch speech recognition and synthetic speech for training applications. We’ve conducted extensive development and testing to ensure that SERA’s speech recognition does not hinder training. SERA carefully listens to and interprets student responses, providing prompt and contextually accurate answers. As a result, students can focus on the training, not the technology.

Repeatable Diversions and Events

Create repeatable diversions and events during a flight, allowing students to target specific weaknesses.

SERA allows instructors to plan out scenario events and diversions (e.g., runway incursions) before the flight begins. If the student goes off course, SERA uses the latest artificial intelligence technology to react and correct the error, just like real ATC.

Updated Data Sets

Furnish accurate airport and navigation data that does not interfere with testing and certification.

Customers across programs share the benefit of new airports and data refinement. ASTi regularly updates SERA’s data package every 28 days, ensuring information is always correct. SERA also uses the same data packages as the Digital Aeronautical Flight Information File (DAFIF) and Aeronautical Radio, Incorporated (ARINC) 424 specifications. As a result, SERA’s updates do not interfere with the customer's testing and certification processes.

Integrated Solution

Assimilate SERA into the customer’s existing simulator without significant development or configuration.

SERA works with a variety of simulators and can drive image generators in multiple formats, including Distributed Interactive Simulation (DIS) and Common Image Generator Interface (CIGI). The host system and instructor operator station can communicate with SERA’s public API. As a result, systems like traffic collision avoidance systems (TCAS) and Automatic Dependent Surveillance–Broadcast (ADS-B) can understand SERA entities. Administrators and instructors can easily configure and manage these settings in the SERA web interface. Contact ASTi to learn more about custom integration options.
