The state vector estimates are derived from navigation avionics on each individual aircraft. Any user may then assemble a surveillance picture of nearby traffic by collecting these reports and comparing them to their own position. Of course, such a surveillance picture only includes aircraft that are equipped with ADS-B avionics and are transmitting their state vector updates. While in the end state one can envision near universal equipage, \"early adopters\" of ADS-B receivers will gain little utility until a significant fraction of the fleet equips. Traffic information system broadcast (TIS-B) is a tool to bridge this transition. TIS-B collects state vector information on aircraft through ground-based surveillance sensors, reformats the information into \"ADS-B-like\" formats, and broadcasts these reports on the common ADS-B channel. This paper describes the test organization and preliminary results from a data collection activity conducted jointly by FAA and industry from May 20-23 at Memphis International Airport to characterize key elements of TIS-B.","PeriodicalId":190149,"journal":{"name":"Proceedings.

Now, CCSDS is branching out to provide new standards for the interchange of information, and the interconnection of subsystems and devices onboard of a spacecraft. This effort is know as Spacecraft Onboard Interface (SOIF). SOIF will publish standards that will allow for the enhanced reuse of spacecraft equipment and software. SOIF expects that these standards will be well known and used within the space community, and that they will be based on or similar to the well-known Internet protocols. This paper will provide a description of the SOIF work by reviewing this work with three orthogonal views. The first of these views is the Protocol view, which describes the protocols and services that are to be implemented in order to provide the users with the advantages of the SOIF architecture. The second of these views is the Services View, which describes the data communications services that are provided to the users. And finally, the Interoperability view provides a description to users how SOIF can be used to interchange between different spacecraft data busses. This paper will give the reader an excellent introduction to the work of the international SOIF team.","PeriodicalId":190149,"journal":{"name":"Proceedings.

This paper identifies some of the major contributions why wiring installed on legacy aircraft has taken center stage. It suggests a planned approach to enhance wiring safety that will improve electronic system performance and reliability. We suggest a two pronged approach: 1. Become cognizant of the technical and operational issues that govern electronic systems robustness and determination of useful life. This is accomplished by providing training to those individuals directly exposed to the aircraft electrical systems during operations. Training can aid management, engineering and technical positions by providing the latest practices that are applicable to the tasks at hand. 2. Apply available technology complementary to the issues of legacy and new design aircraft for systems level diagnostics, prognostics and enhanced life expectancy. Several alternatives in obtaining both of these objectives are presented in this document and is only meant to stimulate the thinking of those readers involved in the everyday operations of aircraft into a more proactive approach to maintaining aircraft electrical systems.","PeriodicalId":190149,"journal":{"name":"Proceedings.

Among these factors are scheduled and actual flight times, flight itineraries, airport capacity, and turn around time between flights. From the existing recorded data, it is possible to present a general profile of both airport congestion and passenger delays, measured with respect to the published schedule, at major airports within the US. This paper illustrates the discrepancy between the two measurements. Airport congestion may be masked by flight schedules which account for routine arrival delays and/or with slack time provided for turn around at an airport. It is possible for an airport to be heavily utilized, with little or unnoticeable at-gate delays (measured with respect to scheduled arrival time). On the other hand, at-gate delays can occur at under-utilized airports. Arrival and departure queuing delays are better indicators of airport congestion than passenger delays. Average flight at-gate delays are derived from performance data and compared with simulation results for 30 of the busiest airports in USA for a good weather day. The effects of variations in schedule flight time and slack time are studied parametrically in the simulation and calibrated to match the recorded baseline national airspace system (NAS) delay profiles. This paper illustrates a technique for estimating NAS-wide impact of propagated flight delays, based upon a method for calibration a system-level simulation against real world delays as well as delays derived from other simulations.","PeriodicalId":190149,"journal":{"name":"Proceedings.

Spurious radiated emissions were efficiently characterized from devices tested in either a semi-anechoic or reverberation chamber, in terms of effective isotropic radiated power. Eight representative handsets (4 GSM, 4 CDMA) were commanded to operate while varying their radio transmitter parameters (power, modulation, etc.). The measurement process and resulting data may subsequently be used by others as a basis of consistent evaluation for cellular/PCS phones, Bluetooth, IEEE802.11b, IEEE802.11a, FRS/GMRS radios, and other portable transmitters. Aircraft interference path loss (IPL) and navigation radio interference threshold data from numerous reference documents, standards, and NASA partnerships were compiled. Using this data, a preliminary risk assessment is provided for CDMA and GSM wireless phone interference to aircraft localizer, Glideslope, VOR, and GPS radio receivers on typical transport airplanes. Existing data for device emissions, IPL, and navigation radio interference thresholds needs to be extended for an accurate risk assessment for wireless transmitters in aircraft.","PeriodicalId":190149,"journal":{"name":"Proceedings.
