“Condensation – Why it Needs to be Addressed in Every Aircraft”

2003-09-08
2003-01-3000
A wide body aircraft carries almost a half–ton of water and ice between the cabin and skin of the aircraft. The water can get on wires and connectors, which can cause electrical problems, cause corrosion and rust, and, eventually, “rain in the plane”. The speaker is the CEO of CTT Systems that has developed a system that solves the condensation by using dry air. The speaker will discuss how condensation can be prevented and how airlines can also save maintenance costs in the process. This topic is relevant for the attendees at the Aerospace Expo, as they are decision makers who need to be aware of this issue. It is also important for the MRO shows as the attendees are on the front lines of dealing with this problem.

“A Dry Aircraft is a Safer Aircraft – Beating Condensation by Using Dry Air”

2003-09-08
2003-01-3017
The airline industry seems to be providing more leisure features on planes like inflight entertainment, Internet access and Digital TV, but it seems the airline industry has ignored the issue of excess condensation on aircraft, which had plagued carriers since the birth of the airline industry. How safe are passengers when a wide body aircraft carries in excess almost a half ton of water and ice between the cabin and skin of the aircraft? Besides the added weight straining the aircraft, excess condensation soaks wires and connectors which can cause electrical shorts. There have been instances of emergency doors frozen shut, locked by ice stemming from excess water dripping inside the plane. Extra water also causes “rain-in-the-plane”, an issue that has gained national attention and causes passenger discomfort. It's time for the industry to address what has become a serious issue.

Wireless Ground Communication in Support of Aircraft Maintenance and Flight Operations

1995-05-01
951387
The wireless Spread Spectrum Ground Communication (SSGC) system will contribute to the enhancement of aircraft maintenance, flight, dispatch, and cargo operations efficiency. A concept layout of the wireless SSGC system implementation in an airport environment is illustrated in Figure 1. The SSGC system will provide both text/graphics data transmission and voice communication for flight crew, maintenance, and dispatch personnel in the airport gate environment. This system will link ground information system and onboard avionics systems, and provide access by ground crew to an information database through portable graphics terminals. The objective is to integrate both airborne avionics, ground crew, and ground based resources into a seamless operating system.
