Following a certification and verification process, the European Commission approved the European Geostationary Navigation Overlay Service (Egnos) “safety-of-life” service for aviation last Wednesday. Egnos is closely similar to, and compatible with, the U.S. Waas satellite-based augmentation system that corrects timing errors in GPS signals, making it more accurate.

Phoenix-based Accord Technologies is at Heli-Expo (Booth No. 7839) to acquaint OEMs, avionics developers and modification centers with its NexNav modular GPS receivers.
The company’s small, low-power receivers are available as circuit card assemblies (CCA) for avionics OEM hosting or as LRUs for aircraft installations. They will support ADS-B, all normal GPS procedures and precision approach requirements.
Accord’s NexNav technology is compatible with Satellite Based Augmentation Systems (SBAS) including WAAS, European EGNOS, Japan’s MTSAT and GAGAN in India.
Eurocopter has improved its Dauphin to offer more modern avionics and enhanced passenger comfort. Certification of the new model, dubbed the N3+, is pegged for late this year.
Visually on the outside, the medium twin will differ from the previous models, as the installation of new radar equipment has prompted a redesign of the nose, which will now resemble that of the EC155.
The French helicopter industry is endeavoring to catch up with the U.S. in satellite-aided precision approaches, as it strives to enable landings and takeoffs at hospitals in IMC. The ultimate aim is to build a solid network of inter-hospital low-altitude IFR routes, according to participants at a forum held by the Toulouse-based air and space academy late last year.
Helileo (Hall 4 Stand E66), a Galileo test bed and expert company located in Aerospace Valley of southwest France, is offering flight testing services to manufacturers of GPS, EGNOS and Galileo receivers. Under an original program, the French start-up company plans to have one engineer testing hardware during French Army pilot training flights operated by Helidax, a private venture, with Eurocopter EC 120 helicopters.
Airbus plans to install satellite-based augmentation systems (SBAS) in its A350XWB to support GPS Cat 1-equivalent 200-foot LPV approaches. SBAS includes the FAA’s WAAS; Europe’s Egnos (2010); India’s Gagan (2011); and Japan’s MSAS (2010/11). The FAA has already published 1,445 WAAS LPV approaches (exceeding the number of ILS approaches) and plans to have 6,000 available by 2018.
Europe’s regulatory body, the European Commission, has issued a Eurocontrol notice of proposed rulemaking (ENPRM) mandating ADS-B after Feb. 5, 2015. At that time, all aircraft operating in European airspace must transmit ADS-B Out signals and meet Eurocontrol’s enhanced mode-S surveillance standards. Currently in the public comment stage until April 8, the final rule is expected in late 2010.
Before GPS, approach classifications were cut and dried–they were either precision (ILS) or nonprecision approaches. But as pilots move into the future, they will need, before considering an approach into an “obstacle-rich environment,” to first navigate through an acronym-rich environment of new terminology to decide how to reach the threshold.
The SESAR (Single European Sky ATM Research) program to define and implement a new air traffic management system for the Single European Sky (SES) presents an opportunity for all stakeholders to work together to develop a common concept of operations (ConOps, in Eurocontrol jargon).
The International Civil Aviation Organization (ICAO) announced it will issue revised standards for helicopter navigation this fall that are intended to take advantage of GPS receiver technology and new types of instrument approach procedures.
