Honeywell late last week received FAA designation as a consultant for Required Navigation Performance Special Aircraft and Aircrew Authorization Required (RNP SAAAR) operational approvals. The move closely follows approval early this month for PlaneView-equipped Gulfstreams to fly RNP SAAAR procedures, which allow more precise approaches and departures, increasing operational efficiency and reducing operating costs, noise and emissions.
While EGNOS, SBAS, GBAS and Galileo may be unfamiliar to most North American aviators, they are key elements in Europe’s determined move to a satellite air traffic control environment. Addressing the FAA’s satellite operations implementation team meeting in December, Eurocontrol officials reported on progress toward their vision of
It took several years for the U.S. and the European Union to reach agreement about satellite navigation systems, but the cooperation agreement the parties signed in June that paves the way for the Galileo and GPS satellite navigation systems should be beneficial to both sides, and to aviation worldwide.
Effective February 20, the /F suffix for aircraft equipped with single FMSs has been revised to account for advanced Rnav equipment.
As part of its evaluation of loran as a potential backup to GPS, the FAA has contracted Rock-well Collins to build a combined GPS/loran variant of its standard multimode navigation and landing receiver. The unit’s primary function will be to provide GPS navigation, with automatic switchover to loran should GPS signals be lost or degraded, and automatic reversion to GPS when normal service resumes.
Researchers at Jeppesen are rethinking the “next evolutionary concepts” in navigation charting in an effort that company officials said will involve a gradual shift away from paper charts in favor of new types of electronic charts. At the top of the heap of ideas seriously being considered is a unique synthetic-vision system (SVS) in which 3-D nav fixes would appear before the pilots’ eyes on the primary flight displays (PFDs).
LAAS could end up being overtaken by a combination of the FAA’s WAAS and Europe’s GPS equivalent, Galileo. While official speakers at last month’s U.S.
A study commissioned by the NGATS Institute on behalf of the FAA’s JPDO and prepared by the advanced engineering and sciences division of ITT determined that eLoran (for enhanced) has “the highest overall preference rating…particularly in the U.S.” as a backup for satnav receivers in the event of failure or interference.
The DOD’s Navstar GPS reached a new performance level this year, with 30 satellites in orbit versus its minimum required civil complement of 24. Four more satellites add signal coverage and reduce the number of occasional “holes,” or gaps where fix geometry can sometimes fall below navigation standards.
A satellite navigation backup study commissioned by the JPDO has given eLoran “the highest overall preference rating...particularly in the U.S.” Not yet publicly released, the 180-page document was prepared by ITT’s advanced engineering and sciences division and assessed seven candidates against a series of essential requirements.
