ACCURATE APPROACH GUIDANCE :
The Global Navigation Satellite System (GNSS) can provide more accurate approach guidance and, in many cases vertical guidance; these features reduce visual maneuvering and enhance safety. The ability to provide better approaches to more runways without any airport infrastructure cost will increase the usability of many airports and reduce delays, diversions and cancellations due to bad weather

DECOMMISIONING OF TRADITIONAL NAVIGATION AIDS:
The availability of GPS based GNSS guidance will allow the phased decommissioning of certain traditional ground-based navigation aids. Operators can now avoid the cost of replacing some traditional aids;

GLOBAL APPLICATION:
GNSS is global in scope and has the potential to support all phases or flight, resulting in a seamless global navigation system and eliminating the need for a variety of ground and airborne equipment, each meeting specific requirements;

ROUTE FLEXIBILITY :
The availability of accurate GNSS-based guidance on departure supports efficient noise abatement procedures. It allows greater flexibility in routing, provides the possibility of lower climb gradients and higher payloads where terrain is a restricting factor;

ENVIRONMENTAL BENEFITS:
GNSS design and use of environmentally beneficial arrival and departure procedures allow the aircraft systems (i.e. The Flight Management System) to manage flight performance (climb, descent, engine performance, etc.). Benefits include reduced fuel emissions and environmentally-tailors noise footprints.
