Performance-Based Navigation and Business Aviation  6
Performance-based navigation promises to make air traffic management more efficient than ever before . . . but what does this mean for business aviation?
GPS Reliability, GDOP and ‘RAIM Holes’  2
The space-based Global Positioning System could be said to be the keystone of the FAA's NextGen ATM modernization but just how reliable is GPS? To find out, we asked John Hansman, Ph.D., an aeronautics professor and researcher at the Massachusetts Institute of Technology.
Honeywell’s Super-Midsize HTF7000 Engine 
According to Honeywell, there are 700 HTF7000-powered aircraft in service with 1,400 engines that have collectively logged more than 2.6 million hours.
Honeywell’s Other Engines 
While Honeywell Aerospace's forward view is firmly fixed on the super-midsize business jet market, the Phoenix-based OEM continues to produce its stable of smaller turbine engines.
HTF7000 From The Cockpit 
Rick Stoulil, chief pilot for Hormel Foods Corp., says: "The way the HTF7000 is set up, it works great. It is equipped with autothrottles and is very responsive [on spool-up] with very little lag. And it's really fuel efficient.
One DOM’s Tale 
The director of maintenance of a large U.S. charter/management company with experience with HTF7000 turbofans half jokes that, while the engine runs well, you do not want to borescope it.
Whatever Happened To The F109?  1
The turbofan for the USAF Fairchild-Republic T-46 advanced trainer was rated at 1,330 lb. thrust and was assigned the designation F109. But the program was canceled after the first 28 F109s were delivered.
GE’s ATP Enters The Turboprop Competition  1
Can GE’s Advanced Turboprop carve out a niche in a market dominated by P&WC’s highly successful PT6A?
P&WC’s Hot Seller 
Introduced to the market in 2012, Pratt & Whitney Canada's PT6A-140 turboprop series has achieved broad acceptance in utility and agricultural markets for both forward-fit and retrofit application on a variety of aircraft.
How Reliable Is FANS? 
It’s reasonable to ask just how reliable are FANS and its constituent parts.
Operating With FANS In Oceanic Airspace  5
What crews should know about the Future Air Navigation System
A ‘Serious Human Factors Issue’? 
While the advantages of ADS-C/CPDLC (or FANS 1/A) are legion, the datalink component is not without its pitfalls that can confuse the inattentive flight crew or one grown complacent due to the automation that characterizes the system.
It's About Efficiency 
Ultimately you're going to have to upgrade to ADS-C and CPDLC to operate above FL 280 in most oceanic airspace anyway (e.g., by Jan. 1, 2020, in the North Atlantic), but here's what you're missing out on now in the North Atlantic Track System.
Building an Oceanic Flight Plan  1
The process of creating a safe, fuel-efficient and regulatory-compliant oceanic flight plan actually begins with the compilation of a comprehensive international operations manual based on standardized procedures and best practices.
A Source For Flight Plan Formats
Looking for a new oceanic flight plan format? Mark McIntyre of Mente LLC advises: "A lot of people aren't aware that international trip planners have a variety of trip flight plan formats. You might want to request a handful of different formats and find one that suits your operation."
