A flight management system (FMS) uses either a performance-based or a geometric VNAV system. A performance-based VNAV system computes a descent path from the top of the descent to the first constrained waypoint using idle or near idle power. This is referred to as an idle descent path at ECON (most economic, or most fuel-efficient) speed.
In 2014, Avidyne began equipping general aviation and business aircraft with the IFD540 and IFD440 navigators incorporating a touch-screen flight management system with full LPV capability. [ 5 ] LPV is designed to provide 25 feet (7.6 m) lateral and vertical accuracy 95 percent of the time. [ 6 ]

Navblue's software creates and uses large aeronautical and navigational databases for flight management systems and flight simulators, as well as ground positioning systems, aircraft simulators, airspace modelling, and air traffic systems. Electronic flight bag software provides Navtech tools to pilots electronically on a laptop or tablet. [12]
Most modern commercial aircraft with auto-pilots use flight computers and so called flight management systems (FMS) that can fly the aircraft without the pilot's active intervention during certain phases of flight.
Universal Avionics Systems Corporation, also known as Universal Avionics, is an international company headquartered in Tucson, Arizona in the United States. It primarily focuses on flight management systems (FMS) and cockpit instrument displays for private, business, and commercial aircraft .
RNP procedures were introduced in the PANS-OPS (ICAO Doc 8168), which became applicable in 1998. These RNP procedures were the predecessor of the current PBN concept, whereby the performance for operation on the route is defined (in lieu of flight elements such as flyover procedures, variability in flight paths, and added airspace buffer), but they resulted in no significant design advantages.
In 1973, Jeppesen NavData® was first used commercially in flight management computer guidance systems (FMCGS). In 1974, Jeppesen entered the flight training business when Times-Mirror merged it with Sanderson Films. [8] 1980s. Jeppesen began a series of acquisitions that added to its product and service offerings:
