Terminal Event: A Novel by James Stewart Thayer »

BOOK REVIEW. This new air crash novel by thriller writer James Thayer is loosely based on the TWA 800 disaster. It depicts the story of a complex air crash investigation as seen through the eyes of a former NTSB investigator whose wife was a victim of the crash. According to AVweb's Phil Kolczynski — an attorney who has been involved in many crash cases at the FAA, DOT, and in private practice — Thayer's latest page-turner is the best of its genre in recent memory, offering unparalleled technical accuracy, believable characters, a tight plot with plenty of action, and a surprise ending.

Three Low Cost Altitude Alerters »

While GPS has revolutionized the way we navigate in two dimensions, the most common cause of pilot violations and CFIT accidents is the pilot’s failure to deal properly with the third dimension: altitude. In this regard, a good altitude alerter can be worth its weight in gold. Once the exclusive province of the turbine crowd, alerters have now come down in price to levels that most G.A. pilots (even renter pilots) can afford. We review three of them: the Icarus AltAlert ($995), the AirSport ($599 to $899), and the CMM Altitude Tracking Module ($249.95). More

Sandel Avionics SN3308 Electronic HSI: EFIS Becomes Affordable »

The SN3308 is the world's first three-inch electronic HSI: small enough to fit in any GA panel, and at $7,895, priced about the same as an ordinary mechanical HSI. But, that's where the similarity ends, because the SN3308 is a magnificent multifunction color display that serves as an HSI, RMI, and moving map, and provides an integrated EFIS-style readout of nav data from your VOR, GPS, Loran, ADF, DME and marker beacon receivers. AVweb editor Mike Busch recently installed one in his Cessna 310 and still can't wipe the smile from his face. Here's Mike's in-depth review of what he calls "a glass cockpit for the rest of us."

Update: The New 406 MHz ELTs »

Now that several manufacturers have come to market with new 406 MHz ELTs, and some have become available that transmit on both the old (121.500 and 243.00 MHz) and new (406 MHz) frequencies, you may be wondering if you should replace your aging ELT or just stick with what you have. AVweb's avionics guru explains that the new units have some compelling advantages, but suggests it might be a bit early to switch and offers some knowledgeable guidance. More

GAMIjectors for Lycomings »

General Aviation Modifications Inc. originally developed its GAMIjectors to correct fuel distribution problems on big-bore Continental engines. Recently, however, GAMI received FAA approval for installation of the precision-balanced injectors on most Lycoming engines as well. The balancing process is quite different for Lycs, but the outcome is the same: a smoother engine that can be leaned aggressively without running rough. AVweb publisher Carl Marbach recently flew his newly re-engined Aerostar to Ada, Oklahoma, for the GAMIjector treatment, and offers this detailed PIREP. More
