Perspectives: Production Variance
As I have read and listened to the discussion of airline profitability and air-traffic control (ATC) problems, punctuated by bankruptcies, delays, congestion, meltdowns, etc., I have concluded the problem, and therefore the solution, lies outside the current...

Perspectives: Being Net-Centric
The concept of network centric operations, or network centric warfare (NCO/NCW), emerged in the 1990s. Then called "C4I for the warrior," it focused on creating a unified battle space for joint military services. NCW may be a new name for it, but...

Letters
LAAS v. WAAS I read William Reynish’s article "Happy Landing for LAAS?" (January 2007, page 30) with great interest. My main responses to the article are these: Boeing, Airbus and the airlines are not interested in WAAS. It was developed for...

Perspectives: Security and the Separation Kernel
Historically, avionics systems have largely been designed to fit a single application need, such as an attitude indicator or central warning system. The software-intense designs of today’s avionics systems are quite a contrast to their analog...

Safety: Inertial System Drift
The most expensive failure of a twin Inertial Reference System (IRS) occurred on the first Ariane V rocket in 1996. Thirty-seven seconds after liftoff, a software fault caused an extreme attitude change, which tore the launch vehicle apart. Apart from...

Perspectives: eLORAN’s Shortcomings
While I share the concern about possible backups to automatic dependent surveillance-broadcast (ADS-B) in the event of GPS local or larger outages, I don’t believe the entire story about Enhanced Loran (eLORAN) is being told. The whole story may help...

Perspectives: Time for Change
How does that old saying go? The only thing that stays constant is change. This is true in commercial avionics, where we have seen a steady progression from analog to digital components. Change is evolutional or revolutionary. Evolutional change is a steady...

Safety: Slippery Swaps
Initially unnoticed by the flightcrew or air traffic control (ATC), an El Al B747–412 (4X–ELS), with 455 persons on board, slipped well below the ILS glideslope (G/S), while on finals to Heathrow on Jan. 10, 2006. An alert controller saw that the...
