The weather at Saratoga Springs, N.Y. on the night of July 13, 2008 was 1,100 overcast, one-and-a-half miles visibility with moderate rain, and wind calm. Albany approach control vectored us for a GPS approach to Runway 5. We intercepted the inbound course toward the airport.
Wide Area Augmentation System
Garmin unveiled a pair of ADS-B units and a new solid-state weather radar system yesterday, further broadening its avionics product line.
The company’s new GDL 88 is a dual-link ADS-B solution, which transmits and receives on 978 MHz and also receives on 1090 MHz. Its ability to receive on both 978 and 1090 MHz means that it can detect traffic transmitting on either ADS-B OUT frequency and receive subscription-free weather data on 978 MHz. ADS-B OUT capability for flying above 18,000 feet or outside the U.S. could be added with a GTX 330/33 ES transponder.
Columbia Avionics & Aircraft Services obtained FAA STC approval to install Garmin GTN 650 and 750 navcoms in the Cessna 500, 501, 550, 551, S550 and 560. This follows a similar STC that the Columbia, Mo.-based company received in May for the Cessna 650. The touchscreen Garmin GTN navcoms are certified for full autopilot-coupled Waas LPV approaches, including vertical guidance. The STC also covers various combinations of the GTN 650/750, Garmin GTX-33ES mode-S transponders, Garmin GDL-69/A weather data link and a marker beacon receiver.
Sagetech is now taking orders for the Clarity line of iPad and Windows tablet/PC ADS-B weather (FIS-B) and traffic (TIS-B) receivers. Two of the Clarity receivers include an AHRS that provides pitch and bank information for synthetic vision apps like Hilton Software’s WingX. The hockey puck-size Clarity units come in four models, ranging from two Core data-only units and two Core SV units with AHRS. The basic Core unit ($699) receives on the 978 UAT ADS-B frequency, which is for aircraft flying below 18,000 feet. The Core Dual ($877) receives on both 978 UAT and 1090ES frequencies.
Children’s Hospital New Orleans received approval June 18 for a new helicopter WAAS LPV approach to bring arrivals down to a height above landing (HAL) of 270 feet. The new procedure allowing more precise guidance in poor weather was developed by Orange Beach, Ala.-based Hickok & Associates.
The market for inexpensive portable ADS-B receivers that deliver free in-flight data to Apple iPads and other devices is heating up. Boston-based Radenna pioneered this market with the original SkyRadar unit, which communicates wirelessly with the iPad, providing a means to receive free in-flight weather and traffic data from the growing ADS-B ground station network.
EU-funded project Accepta is co-funding the publishing of Egnos (European Geostationary Navigation Overlay System) landing procedures and/or installing its navigation equipment at 40 additional airports in 11 European countries by the end of 2013. The countries soon to get the system at their airports include Finland, France, Italy, UK, Austria and Spain. Egnos, Europe’s equivalent of Waas GPS, has many benefits including operational, economic (especially for business aviation), safety and environmental, said the company.
Last month AIN reported on the disturbing increase in reports of GPS interference and deliberate jamming and raised the question of continuing GPS reliability if these incidents (attributable to small portable jammers used by truckers to obfuscate their whereabouts) increase in numbers and transmitted power.
It’s clear that the final release of the FAA’s Authorization Act has given a new fillip to the agency’s NextGen implementation activity. The 2012 Plan, released in March, has a much more upbeat flavor than its 2011 predecessor, which essentially looked backwards at accomplishments in 2010, when most activities were still in their early stages. Back then, the potential future benefits of NextGen were just that–potential.
Nextant Aerospace is several STCs closer to receiving EASA certification for its remanufactured Beechjet 400A and XT models. The company’s 400XT has already received FAA certification. Two of the supplemental type certificates cover several major operational areas, including Class A terrain awareness and warning systems (Taws) as well as a wide area augmentation system (Waas). Other STCs cover a number of in-flight entertainment options. Earlier deliveries already included the equipment necessary for certification.
