L-3 Aviation Products has been selected to provide its GH-3900 electronic standby instrument system (ESIS) for new production Viking Twin Otter Series 400 aircraft. Canadian-based Viking holds the type certificates for seven legacy de Havilland aircraft — DHC-1 through DHC-7 — and manufactures the 400 Twin Otter. The GH-3900 ESIS is designed to Level A software and hardware standards and can be customized to fit a range of primary systems.
There is something strangely prehistoric about the way many of us continue to fly what we grew up calling a “non-precision” instrument approach. After flying across continents and oceans with navigational precision measured in decimals, we push the nose over a thousand feet per minute “or so” and wait for the minimum descent altitude (MDA). That altitude is measured with an altimeter accurate to plus or minus 75 ft., plus whatever temperature tolerances may exist, and based on an altimeter setting that may be an hour or more old.
It’s one thing to perform an autorotation correctly in the simulator or during a “canned” training session but quite another matter when the engine quits in flight. It’s during the latter that a pilot is prone to revert to first-learned habit patterns. They had better be the right ones, since action is required within 2 sec.
We might not think about it until we have to land at one, but as business jet captain Katha House pointed out, there are a few airports around the globe that are situated below sea level. “Thermal Airport [KTRM] in the Mojave Desert is 115 ft. below sea level,” she said, “and your altimeter will read zero on the approach, and you’ll still be flying! There’s one in Egypt that’s 436 ft. below sea level, and Bar Yehuda Airport [LLMZ] at Masada in Israel is -1,240 ft., the lowest in the world.”
StandardAero’s facility at Seletar Aerospace Park in Singapore was recognized as an authorized maintenance repair and overhaul center for Rolls-Royce RR300 helicopter engines. The authorization follows a similar agreement signed in December for StandardAero’s facility in Winnipeg, Canada. The Singapore agreement extends through 2021. StandardAero’s RR300 line will run parallel to the facility’s Rolls-Royce M250 line. The 32,000-sq.-ft. facility is equipped for full repair and overhaul, and test capabilities.
Last year, after the U.S. Department of Transportation (DOT) released its Notice of Proposed Rulemaking (NPRM) for charter brokers, I prophesized that “2014 might see the industry step in and create voluntary broker rules and a registry of those who meet these standards.”
