Airservices Australia commissioned two new ground stations to support its national automatic dependent surveillance-broadcast (ADS-B) network as the country’s first ADS-B mandate approaches. Australia’s Civil Aviation Safety Authority (CASA) requires that aircraft flying above 29,000 feet be fitted with ADS-B avionics by December 12.

Extension of Comment Period on Use of Enhanced Flight Vision Systems (EFVS) and Pilot View Requirements for Vision Systems
During day two of the U.S. government shutdown, 15,000 FAA employees were still off the job on furlough and the business aviation community appears to have found the early impact of the closure to be greater than anticipated with disruption to several important FAA functions that were not impacted by previous Federal government shutdowns.
The FAA has released a notice of proposed rulemaking (NPRM) that would allow many more operators to continue flying below decision altitude/decision height or minimum descent altitude (DA/DH or MDA) during IMC when equipped with enhanced flight vision systems (EFVS). Such systems generally use infrared sensors to deliver real-time images of the external view to cockpit displays, and the new rules would not apply to synthetic vision systems. Millimeter-wave radar could also be used for future EFVS operations.
Miami Approach Control recently reissued guidance on how it plans to handle practice instrument approach requests for aircraft in the local area. For example, standard IFR separation will be applied to all aircraft. Aircraft requesting a procedure turn or a traditional holding pattern are expected to inform the approach controller on initial contact. The facility also reminds pilots that clearance for an approach does not authorize the aircraft to fly the published missed approach without previous authorization.
Helicopter pilots unexpectedly straying into IFR conditions and losing control of their aircraft has been identified as the cause of the greatest number of rotorcraft fatalities, according to the International Helicopter Safety Team (IHST). The group, which is focused on greatly reducing helicopter accidents by 2016, has reported that NTSB figures from 2011 indicate that 45 of 52 such accidents proved fatal to occupants. “That means the chances of surviving an inadvertent encounter with IFR are just 14 percent,” according to IHST.
Steve Hickok is understandably proud of the work his company has done to bring safe and reliable GPS-enabled lateral navigation (LNAV) and localizer performance with vertical guidance (LPV) approaches to helicopter operators across the U.S. In fact, every helicopter Waas LPV approach approved since 2008 has been developed by Hickok & Associates (Booth No. N6204.)
Unmanned aircraft system (UAS) operators in the U.S. would have to file and fly instrument flight plans and equip their aircraft for position reporting with transponders and automatic dependent surveillance-broadcast Out (ADS-B Out) transmissions based on GPS.
The old Terminal Instrument Procedures Working (TWG) group has been disbanded, and the new U.S Instrument Flight Procedures Panel (IFPP) is taking its place. The TWG was formed in an era when instrument approach procedures were designed around land-based navaids. Because the FAA has committed itself to developing a National Airspace System built to performance-based navigational standards (PBN), the agency believed the complexities inherent in these designs demand a more comprehensive working group.
So-called human factors and a series of small technical snags in the Indonesian air traffic control system led to the crash of Sukhoi Superjet 100 S/N 95004 on May 9 outside Jakarta, in which 45 people died, according to a final accident report released Tuesday by Indonesia’s National Transportation Safety Committee.
