Lufthansa Technik (LHT) is studying ways to reduce the loads imposed on a bizliner’s interior walls and their structural attachments by a sudden drop in cabin pressure. The solution appears to lie in installing large cutouts in the walls and floor.
Apple’s new iPad Air, which is thinner and weighs one-third of a pound less than the previous-generation iPad, has passed rapid decompression testing conducted by Jeppesen. The company tested the iPad Air to 51,000 feet, similar to tests conducted on all previous iPad versions. “No anomalies were detected during testing of any of the iPad models,” according to Jeppesen, which makes the Mobile FliteDeck and FliteDeck VFR apps for the iPad.
Essex Industries (Booth No. N4930) is promoting two new emergency breathing devices here at NBAA.
The Self-Contained Unit (SCU) is an emergency-breathing hood that protects for up to 60 minutes against smoke, carbon dioxide, lack of oxygen or decompression. The hood dons in less than 15 seconds and provides 360-degree visibility and allows the wearer to hear, talk, and move freely. It has a 10-plus-year shelf life.
The FAA has issued an airworthiness directive for the Boeing 737-600, -700, -700C, -800, and -900 series. The AD was prompted by a report of cracks found in the skin at body station 540 just below stringer S-22L on a 737-700.
It’s a simple concept: if you can flight plan a higher altitude to use during an overwater emergency, then you might not need as much extra fuel to reach an alternate airport. Most airlines and business jet operators flight plan for an emergency altitude of 10,000 feet, because supplemental oxygen isn’t needed at that altitude, when flying from the equal-time point to an alternate airport.
