Application of fuel/time minimization techniques to route planning and trajectory optimization

Rising fuel costs combined with other economic pressures have resulted in industry requirements for more efficient air traffic control and airborne operations. NASA has responded with an on-going research program to investigate the requirements and benefits of using new airborne guidance and pilot procedures that are compatible with advanced air traffic control systems and that will result in more fuel efficient flight. The results of flight testing an airborne computer algorithm designed to provide either open-loop or closed-loop guidance for fuel efficient descents while satisfying time constraints imposed by the air traffic control system is summarized. Some of the potential cost and fuel savings that are obtained with sophisticated vertical path optimization capabilities are described

Description of the primary flight display and flight guidance system logic in the NASA B-737 transport systems research vehicle

A primary flight display format was integrated with the flight guidance and control system logic in support of various flight tests conducted with the NASA Transport Systems Research Vehicle B-737-100 airplane. The functional operation of the flight guidance mode control panel and the corresponding primary flight display formats are presented

Experimental determination of position-estimate accuracy using back-azimuth signals from a microwave landing system

Flight tests using the Boeing 737 airplane to obtain position estimates with back azimuth signals from a microwave landing system (MLS) are discussed. The equations and logic used to generate a navigation position estimate in the MLS back azimuth signal environment are described. The error in the navigation position estimate is determined. A summary of the Boeing 737 position estimate update process is described. The navigation position estimate error calculated flight data and radar tracking information is analyzed. The position estimate error data using the MLS inputs are compared with error data obtained during dual distance measuring equipment updates

Processing the Therapeutic Relationship

The authors propose that if therapists and clients process their therapeutic relationship (i.e., directly address in the here and now feelings about each other and about the inevitable problems that emerge in the therapy relationship), feelings will be expressed and accepted, problems will be resolved, the relationship will be enhanced, and clients will transfer their learning to other relationships outside of therapy. The authors review theories supporting the idea of processing the therapeutic relationship, discuss the relevant empirical literature in this area, and provide their conceptualization of the construct of processing the therapeutic relationship based on the theory and empirical findings. Finally, they discuss methodological concerns and suggest implications for clinical practice, training, and further research

Introduction to a Special Issue on Disclosure and Concealment in Psychotherapy

Given that questions related to disclosure have long held the interest of both clinicians and researchers, we are excited to present this special issue of Counselling Psychology Quarterly focusing on disclosure and concealment in psychotherapy. All forms of human communication involve some degree of disclosure, whether through verbal or non-verbal means. Most of us are quite careful about both the content and quantity of what we share with others. One factor that affects decisions about disclosure is the type of relationship. Friendships typically include an approximately equal amount of disclosure from both members, whereas in other relationships (e.g. parent–child, boss–employee), disclosure patterns may be less equal. Psychotherapy is one such relationship where participants likely do not disclose equally. Clients are expected to reveal themselves as much as possible so that therapists can help them, although the depth of such disclosures may gradually evolve as clients begin to feel safe with their therapists. In contrast, given that the purpose of psychotherapy is to help the client, therapist self-disclosure (TSD) is usually much more limited and ideally used only to help the client rather than meet therapists’ needs. Because psychotherapy is on the one hand much like a friendship, given the level of intimacy and sharing (Schofield, 1986), yet on the other hand a professional relationship focused on the client, it offers a rich opportunity for examining the disclosure process. We can consider disclosure to exist on a continuum. At one extreme, nothing is withheld and the person is completely open with all conscious thoughts and feelings. At the other extreme, a person does not disclose at all and in fact, might be actively concealing or lying. Few people live at the extremes, as it is almost impossible either to share or withhold all thoughts and feelings. In addition, it is important to recognize that disclosure is a state rather than a trait, such that although one may be generally open, that same person might not disclose in a particular given situation. For this special section, then, we focus on several aspects of this disclosure continuum. First, we focus on TSD. Next, we focus on client disclosure and concealment. We refer readers to prior reviews of the literature to gain more perspective on past research in this area (Henretty, Berman, Currier, & Levitt, 2014; Henretty & Levitt, 2010; Hill & Knox, 2002; Knox & Hill, 2003)

The Use of Dreams in Modern Psychotherapy

We review theories of dream work. We also review the empirical research about how dreams are used in psychotherapy, as well as the process and outcome of different models of dream work. Finally, we review how dream content can be used to understand client, the role of culture in dream work, client and therapist dreams about each other, and training therapists to do dream work

Manual flying of curved precision approaches to landing with electromechanical instrumentation. A piloted simulation study

A piloted simulation study was conducted to examine the requirements for using electromechanical flight instrumentation to provide situation information and flight guidance for manually controlled flight along curved precision approach paths to a landing. Six pilots were used as test subjects. The data from these tests indicated that flight director guidance is required for the manually controlled flight of a jet transport airplane on curved approach paths. Acceptable path tracking performance was attained with each of the three situation information algorithms tested. Approach paths with both multiple sequential turns and short final path segments were evaluated. Pilot comments indicated that all the approach paths tested could be used in normal airline operations

Preliminary test results of a flight management algorithm for fuel conservative descents in a time based metered traffic environment

A flight management algorithm designed to improve the accuracy of delivering the airplane fuel efficiently to a metering fix at a time designated by air traffic control is discussed. The algorithm provides a 3-D path with time control (4-D) for a test B 737 airplane to make an idle thrust, clean configured descent to arrive at the metering fix at a predetermined time, altitude, and airspeed. The descent path is calculated for a constant Mach/airspeed schedule from linear approximations of airplane performance with considerations given for gross weight, wind, and nonstandard pressure and temperature effects. The flight management descent algorithms and the results of the flight tests are discussed

Teaching Graduate Trainees How to Manage Client Anger: a Comparison of Three Types of Training

The authors examined the effects of three types of training (supervisor-facilitated training, self-training, biblio-training) on 62 graduate student therapists\u27 state anxiety, self-efficacy for dealing with anger, and helping skills (i.e., reflections and immediacy) in response to videotaped vignettes of angry clients. Training overall was rated as very helpful, and trainees increased in self-efficacy for working with client anger. Supervisor-facilitated training was rated as more helpful than, and was preferred to, self-training and biblio-training; it also led to more reflection of feelings in response to clients. Results suggest that vignettes such as these might be a helpful adjunct to training once students have competency in the basic helping skills

Description of the computations and pilot procedures for planning fuel-conservative descents with a small programmable calculator

A simplified flight management descent algorithm was developed and programmed on a small programmable calculator. It was designed to aid the pilot in planning and executing a fuel conservative descent to arrive at a metering fix at a time designated by the air traffic control system. The algorithm may also be used for planning fuel conservative descents when time is not a consideration. The descent path was calculated for a constant Mach/airspeed schedule from linear approximations of airplane performance with considerations given for gross weight, wind, and nonstandard temperature effects. The flight management descent algorithm and the vertical performance modeling required for the DC-10 airplane is described
