By the time hypoxia is detected, it’s often too late, and the higher the cabin altitude, the less time pilots have to realize that they need to don oxygen masks.
Despite the first day of spring being just a few weeks away, encounters with icing at altitude still represent a very real problem. Responsibility for understanding the intricacies of ice formation, as well as how to exit an area of icing before a loss of aircraft control occurs, still falls on the cockpit crew. Here are some valuable icing resources that are easily accessed from any Internet connection that are worth bookmarking for next year’s season.
Twin Commander Aircraft has developed a pressurization leak kit for rudder-pedal horns. Leaks in the boots that enclose the rudder-pedal horns can result in a noticeable loss of pressure differential, meaning a higher cabin altitude at cruise. Twin Commander’s new rudder-pedal seal kit includes a plug for the rudder-pedal horns/brake valve arms and improved boots that help preserve cabin pressurization.
Twin Commander Aircraft has developed a rudder-pedal seal kit that it says virtually eliminates pressurization leaks in a troublesome area. Leaks in the original boots that enclose the rudder-pedal horns can lead to a noticeable loss of pressure differential, resulting in a higher cabin altitude at cruise. Twin Commander’s new rudder-pedal seal kit includes a plug for the rudder-pedal horns/brake valve arms and improved boots that help preserve cockpit and cabin pressurization.
Anti-icing surfaces under development at GE and EADS could one day reduce and possibly even eliminate the need for existing anti-icing techniques. Research organizations at the two major aerospace companies are currently working on surfaces that would naturally repel ice without using energy.
Embry-Riddle Aeronautical University has taken delivery of a Mentor advanced aircraft training device built by Frasca. The trainer will be used in studies of hypoxia, or oxygen deprivation, in the university’s Normobaric lab. The Mentor replicates a Cessna 172 cockpit complete with Garmin G1000 avionics and a Truvision visual system.
The American Association of Airport Executives (AAAE) and National Air Transportation Association (NATA) both recently submitted comments to the Environmental Protection Agency (EPA) on proposed new rules for limiting de-icing fluid runoff at commercial airports. The EPA proposal would establish standards for the amount of aircraft de-icing fluid that airports must recapture and prevent from entering wastewater runoff.
International Water-Guard has marked some highlight events recently, among them delivery of its 2,000th water treatment unit (for installation in a Dassault 2000LX) and delivery of the first of the new IWG-A6 unit to Gulfstream Aerospace for the new G650.
Gulfstream Aerospace has reinstituted its “Meet the Quote” spare parts price-matching program, initially launched in March 2004, and operators have until July 31 to enjoy the savings. The program includes price matching on the most popular exchange parts, including valves, alternators, regulator and brake assemblies, actuators and display units. The offer is extended to operators of all Gulfstream jets.
Writing in the spring 2000 issue of the FAA’s Federal Air Surgeon’s Medical Bulletin, Rogers Shaw, team coordinator of the FAA’s Civil Aerospace Medical Institute’s aeromedical education division’s airman education program, offered these tips for heading off the dangers of dehydration:
• Drink cool (40 deg F) water (forget the old theory that lukewarm water is absorbed more quickly into the system).
