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 ]
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 .
System Performance: Avionics systems must meet performance benchmarks as defined by the FAA, ensuring they function correctly in all phases of flight. Certification : Shops performing installations must be FAA-certified, and their technicians often hold certifications such as the General Radiotelephone Operator License (GROL).
There are several levels to most standards. A low-safety product such as an in-flight entertainment unit (a flying TV) may escape with a schematic and procedures for installation and adjustment. A navigation system, autopilot or engine may have thousands of pages of procedures, inspections and rigging instructions.
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.
SLOP allows aircraft to offset the centreline of an airway or flight route by a small amount, normally to the right, so that collision with opposite direction aircraft becomes unlikely. In the North Atlantic Region pilots are expected to fly along the oceanic track center-line or 1 or 2 nautical miles to its right, randomly choosing one of ...
