The Houston Metroplex project took a step forward toward full NextGen usage on May 29 with the implementation of a number of new performance-based navigation procedures (PBN). The local controlling body, Houston Center, eventually plans to bring 60 new procedures online for George Bush Intercontinental Airport, Houston Hobby and a number of satellite airports in the area.
After AIN published an article recently about approvals required to fly LPV approaches outside the U.S., a helpful pilot reader offered additional useful information. The story explained, “This requirement [the need for a letter of authorization] flies in the face of the deviation the FAA filed from ICAO requirements that do not require Part 91 operators to obtain approval for any performance based navigation (PBN) procedures.”
The FAA does not require a letter of authorization to fly a localizer performance with vertical guidance (LPV) approach within the U.S. However, guidance for flying in other parts of the world–such as in Europe where the number of LPV approaches is growing–is not nearly as clear and straightforward.
The rapid growth of China’s civil aviation sector has made air traffic management (ATM) efficiencies all the more important as the country strives to keep up with the demand for air travel.
Facing the demands of increasing air traffic capacity and operational efficiency, the countries of the Asia Pacific region have launched various programs to adopt recent advances in Air Traffic Management and advances inavionics technology over the past couple of decades. Some countries (notably Australia) have forged ahead, while others are further behind, but it is hoped that recent developments could see closer cooperation for an eventual move to a whole-area solution.
The Performance-based Operations Aviation Rulemaking Committee (PARC) last week publicly released the final report that its Flight Deck Automation (FDA) working group delivered to the FAA in September. The FDA group was established by PARC, which provides industry-led guidance for the FAA, to address the safety and efficiency of modern flight-deck systems for flight-path management, including energy-state management, for both current and future operational use.
Because air traffic controllers are increasingly making traffic separation decisions based upon an aircraft’s global navigation satellite system (GNSS) capability–or lack thereof–the FAA has begun updating aircraft equipment suffixes for traffic operating in U.S. domestic airspace. For instance, a GNSS-equipped aircraft may now fly a random route without the need for ATC radar monitoring, where previously radar was always required.
UK air navigation services provider NATS has started a 14-week “consultation” process through January 21 to gather comments from airlines and other interested groups on proposed airspace changes surrounding Gatwick and London City airports. The consultation marks the first step in a wider program of proposed changes under the UK Civil Aviation Authority’s Future Airspace Strategy, an ATC modernization plan for the UK and Ireland.
It is becoming more and more likely that in coming histories of aviation, the key major milestones will include the introduction of jet aircraft, the widespread adoption of satellite positioning and the arrival of required navigation performance (RNP). Jets and satnav are now irreplaceable elements that we take for granted.
Prominent aviation industry figures fear that a list of priorities developed to keep the NextGen ATC modernization effort on track during a time of funding pressure and ongoing “sequestration” budget cuts in the U.S. could undermine the ambitious, two-decade effort.
