The Role of Aircraft Recorders in Human Performance Investigations

1983-10-03
831414
Efforts to learn the reasons why these apparent errors in behavior or performance occur have been largely speculative until Flight Data Recorders and Cockpit Voice Recorders became available in large transport aircraft. Two accidents are examined in which the data provided by the aircraft recorders were employed to explain the underlying reasons for the sequence of events that culminated in the accidents. ...Two accidents are examined in which the data provided by the aircraft recorders were employed to explain the underlying reasons for the sequence of events that culminated in the accidents. ...It is concluded that aircraft recorders are essential basic tools of the human performance investigator requiring quality, dependability and state-of-the-art equipment to refine the investigative methodology of human performance investigations.

American Airlines' Maintenance Recorder Experience

1970-02-01
700317
Fifteen American Airlines BAC 1-11 airplanes have been equipped with electronic engine maintenance recorders for the purpose of evaluating the feasibility and merits of automatic maintenance recording on air transport aircraft. ...The maintenance recorder system and method of data reduction are briefly described. The experience gained to date from this program is portrayed.

Air Transport Flight Parameter Measurements Program – Concepts and Benefits

1980-09-01
801132
A program is described in which statistical flight loads and operating practice data for airline transports in current operations are obtained from existing onboard digital flight data recorders. These data, primarily intended for use by manufacturers in updating design criteria, were obtained from narrow-body and wide-body jets.

Health Monitoring of Electro-Pneumatic Controlled Systems Using Multivariate Latent Methods: An Experimental Validation

2013-01-15
2013-01-9097
Electro-Pneumatic systems exhibit highly nonlinear characteristics due to air compressibility, the presence of friction and the nonlinearities of control valves. Monitoring by acquiring the system's transfer function accurately can be difficult for nonlinear systems. This paper outlines a new idea that one can deal with the electro-pneumatic system as a black box, and using a multivariate technique called principal component analysis (PCA) and projection to latent structure discriminant analysis (PLSDA) to provide robust information about the system's condition. The monitoring system has been experimentally validated for an electro-pneumatic printing machine system using vibration, pressure and displacement sensory data integration using PCA-PLSDA algorithm. Experiments were conducted under two pressures for three artificially conditions: normal, throttled, and leaking system.

The Seat Interference Potential as an Indicator for the Aircraft Boarding Progress

2017-09-19
2017-01-2113
Passenger boarding is always part of the critical path of the aircraft turnaround: both efficient boarding and online prediction of the boarding progress are essential for a reliable turnaround progress. However, the boarding progress is mainly controlled by the passenger behavior. A fundamental scientific approach for aircraft boarding enables the consideration of individual passenger behaviors and operational constraints in order to develop a sustainable concept for enabling a prediction of the boarding progress. A reliable microscopic simulation approach is used to model the passenger behavior, where the individual movement is defined as a one-dimensional, stochastic, and time/space discrete transition process. The simulation covers a broad range of behaviors and boarding strategies as well as the integration of new technologies and procedures.

World's First VTOL Airplane Convair/Navy XFY-1 Pogo

1996-11-18

The Convair/Navy XFY-1 VTOL fighter was ahead of its time. In the early 1950s it became the first airplane to take off vertically, hover, transition to high speed level flight, transition back to hover, and land vertically. Pilot “Skeets” Coleman made a number of successful flights at Moffett Field South of San Francisco, at Brown Field near the California/Mexican border, and at San Diego's Lindbergh Field. This “first of a kind” aircraft soon adopted the name “POGO”. The POGO with its stall proof delta wing had near perfect aerodynamic characteristics in hover, transition and level flight. There were no “black boxes” needed for stability augmentation. The POGO was one of the very first aircraft to use hydraulic power flight controls - a system used today on all modern fighter and transport aircraft.
