TrueCourse™ FMS improves fuel efficiency while enhancing operational capability for the war fighter.

Flight PlanningThe flight planning function provides for the assembly, modification, and selection of active and secondary flight plans. Data can be extracted from the navigation data base that contains flight plans, navigational aids, airways, waypoints, published departure and arrival procedures, and approaches along with associated missed approach procedures, etc. The selection of flight planning data is done through the pilot interface, through uploading of pre-planned navigation data, or through the data link function.

Features

• Guides pilot in creation of FAA compliant Flight Plans

• Integration of Civil Airspace Rules and Restrictions

• Provides worldwide Navigation Database (NDB)• Waypoints, Airways, Airports,

and Runways• Standard Instrumented

Departures (SIDS)• Standard Arrivals (STARS)• Precision Approaches• In-flight modifications to flight

plans

Lateral NavigationThe Lateral Navigation function operates on the flight plans provided by the Flight Planning function, and computes a detailed, continuous, flyable lateral (2-dimensional) flight path consisting of curved and straight path segments that achieve the goals of the flight plan elements (waypoints, procedures, etc.) while taking into account aircraft and autoflight systems performance limitations as well as civil airspace rules and restrictions.

Features

• Waypoint-to-Waypoint• Airways• World Wide SIDs and STARS • Precision and Non-Precision

Approaches

Vertical Performance OptimizationThe Vertical Navigation function operates on the flight plans provided by the Flight Planning function, and computes a detailed continuous, flyable vertical flight path (4-dimensional) over the lateral path provided by the Lateral Navigation function. The Vertical Path is optimized to meet the mission goals while taking into account aircraft performance limitations, pilot-entered constraints, and civil airspace rules. The paths and/or segments of paths can be optimized for minimum fuel consumption, minimum time, maximum loiter, or to meet a time constraint at a waypoint.

Features

• Integrated with Lateral Profiles• Optimized Vertical and Thrust

Profiles• Minimum Fuel Flight Profiles• Minimum Time Flight Profiles• Required Time of Arrival (RTA) at a

Waypoint (Constrained Minimum Fuel)

• Maximum Loiter• Flight Envelope Protection

NavigationThe navigation function furnishes continuous, real-time, three dimensional solutions to the crew and provides the following navigational outputs: estimated aircraft position (latitude, longitude, and altitude), aircraft velocity, drift angle, track angle, magnetic variation, wind velocity and direction, time, and an estimate of actual navigation performance, The navigation function automatically selects the combination of available sensors that provides the best solution for estimating the aircraft position and velocity. Using the sensor accuracy characteristics, sensor raw data, and information about the current conditions, the best combination of position sensors (GNSS, IRU, DME, VOR, etc.) is selected to minimize the position determination error

Advanced Airspace FeaturesTrueCourse™ FMS provides many advanced features to support the state-of-the-art in both today’s airspace and Next Generation civil airspace. This includes the ability to provide up to Required Navigation Performance (RNP) 0.1 procedures, Required Time of Arrival (RTA) capability accurate to 5 seconds, continuous descent approach, precision approaches including RNP 0.1, GPS Landing System (GLS) and FMS Landing System (FLS) approaches, and future support for trajectory negotiation with the civil air traffic control automated systems.

Features

• RNAV/RNP 0.1• Required Time of Arrival (5

seconds)• Continuous Descent Approach• Performance Based Navigation• LP/LPV Approach Integration• Trajectory Negotiation with Air
