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.
A flight management system (FMS) is a fundamental component of a modern airliner's avionics. An FMS is a specialized computer system that automates a wide variety of in-flight tasks, reducing the workload on the flight crew to the point that modern civilian aircraft no longer carry flight engineers or navigators. A primary function is in-flight ...
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]
SLOP is recommended for use in modern flight management system-based, RVSM (reduced vertical separation minima)-equipped aircraft operations to mitigate the midair collision hazard, which is amplified by the accuracy of modern aircraft navigational technology and onboard flight instruments.
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.
The Garmin G1000 is an electronic flight instrument system (EFIS) typically composed of two display units, one serving as a primary flight display, and one as a multi-function display. Manufactured by Garmin Aviation , it serves as a replacement for most conventional flight instruments and avionics .
In aviation, lateral navigation (LNAV, usually pronounced el-nav) is azimuth navigation, without vertical navigation (VNAV). Area navigation (RNAV) approach plates include LNAV as a non-precision instrument approach (NPA). When combined with VNAV, the resulting instrument approach, LNAV/VNAV, is referred to as an Approach with Vertical Guidance ...
