Under most conditions, pilots are able to successfully understand the avionics during flight. There are times, however, when the pilot may not be totally aware of what the avionics are doing, why an action is being performed, and what the automation will do next. Explanations of these conditions that lead to aviation surprises have included many relating to the lowered situation awareness of the pilot during these times. It has also been shown that several vertical guidance modes are not displayed which lead to a pilot loosing track of the current mode of operation, especially during periods of high mental workload and multi-task performance. This paper suggests ways to improve situation awareness in a dynamic flight environment.","PeriodicalId":332554,"journal":{"name":"15th DASC.

This includes the technologies and corresponding infrastructures which are arising in response to the Consumer Portable Electronics COTS market. This paper argues that innovative use of emerging commercial packaging technologies will be required for military avionics OEMs to survive and compete; especially as we move towards the year 2000 in an environment where the rules and rites of classical military procurement are fading. Three emerging packaging technology areas have been identified as being key enablers for realizing low cost reliable avionics systems. The technology areas are: area array interconnects; advanced PWB technologies; composite materials for heatsinks. The movement towards area array interconnection is the impetus behind development of the mentioned enabling technologies. These technologies will be useful to Avionics OEMs whether for new designs or for the repackaging of commercial architectures for insertion into tactical environments.","PeriodicalId":332554,"journal":{"name":"15th DASC.

Although these devices were not perceived as a problem in the past, the proliferation of computer-based electronic devices, small radio receivers, transceivers, telephones, and video cameras has created a new class of problems for both modern and older civil transport aircraft. The proliferation of the PED has, in essence, changed the operational environment of today's aircraft. A portion of the paper is an examination of the results of a search of the Aviation Safety Reporting System (ASRS) database for suspected cases of electromagnetic interference. A number of reports have been entered into the database that indicate potential problems caused by PEDs. The difficulties in addressing the PED problem are discussed. This discussion involves regulations, guidelines, and airline policy relevant to the PED problem.","PeriodicalId":332554,"journal":{"name":"15th DASC.

This paper explores key cockpit technologies and procedures that enhance aviation safety and, at the same time, are cockpit enabling technologies for free flight. These enabling technologies are integrated through two complementary operational concepts known as Flight Operations and Air Traffic Management Integration (FTMI) and Situational Awareness for Safety (SAS), with due consideration given to human factors. These two concepts, along with their supporting avionics, data links, and ground-side air traffic and Flight Information Service (FIS) infrastructure, make free flight a distinct technical possibility.","PeriodicalId":332554,"journal":{"name":"15th DASC.

The FMS-equipped aircraft operated initially in the domestic environment. Eventually, FMS-equipped aircraft operated on very long segments, such as Los Angeles to Hong Kong, which often required operation of the aircraft at multiple limits such as maximum takeoff weight, maximum fuel capacity, and/or specified fuel reserves. These limits are not fully considered by the current generation FMS in attempting to optimize the speed schedule. Software enhancements to this speed schedule logic could bring economic benefits to airlines flying these operationally challenging flights.","PeriodicalId":332554,"journal":{"name":"15th DASC.

The assessment process is a combination of analysis, simulation, and tests and is currently under development for demonstration at the NASA Langley Research Center in the High Intensity Radiated Fields (HIRF) Laboratory and Closed-Loop Test (CLT) Laboratory. The assessment process is comprehensive in that it addresses (i) closed-loop operation of the controller under test, (ii) real-time dynamic detection of controller malfunctions that occur due to the effects of electromagnetic disturbances caused by lightning, HIRF, and electromagnetic interference and incompatibilities, and (iii) the resulting effects on the aircraft relative to the stage of flight, flight conditions, and required operational performance. In addition, this method uses electromagnetic field modeling codes to determine internal electromagnetic environments to which onboard electronic equipment will be subjected. Lower cost demonstrations of certification compliance should be realizable using this method due to the reduction or elimination of costly full-aircraft tests.","PeriodicalId":332554,"journal":{"name":"15th DASC.
