Naval aviation is on the brink of taking advantage of a 12 year old capability. Naval commercial derivative aircraft have had the ability to navigate in instrument meteorological conditions using global positioning technology for nearly as long as civil commercial-for-hire aircraft. However, tactical naval aircraft, like the E-2C Hawkeye, are now only beginning to obtain and install the necessary technology to meet federal aviation regulations for satellite based area navigation. Worldwide airspace controlling agencies have mandated the use of navigation equipment that meets highly specific performance standards prior to entry in required navigation performance airspace. Aircraft not compliant with these standards are denied flight clearance or experience clearance delays. The Department of Defense has issued policy guidance that allows military aviation organizations to self-certify satellite based navigation technologies to meet required navigation performance standards. In many ways, military navigation technologies far exceed the performance requirements for civil and international airspace use. These technologies, however, are highly specific in their mission orientation and must demonstrate their compatibility with civil aviation standards. This study focused on the source and the specifics of navigation performance requirements. Domestic and international regulations and policies were reviewed as they pertain to civil aviation, and then applied to military aviation. Critical technical standards documents were reviewed to determine the best strategy for complying with civil and international regulations. Lessons learned from previous E-2C navigation system evaluations were also reviewed and incorporated within this compliance strategy. Compliance and self-certification responsibilities belong to aircraft specific program managers within the Navy’s acquisition organization. Sophisticated navigation systems incorporating satellite positioning technology require a tailored approach toward compliance demonstration. Military receivers with precise positioning capability satisfy many of the required availability, accuracy and containment standards. To satisfy civil requirements, correctly keyed, military navigation systems may be evaluated according to standards typically applied to the most highly augmented standard civil systems. This thesis contains a comprehensive list of compliance items selected for their applicability to the E-2C Hawkeye mission.

The scientific objective of this study is to design an aircraft flight experiment that will provide airborne imaging data, augmenting satellite data, to advance the fundamental understanding of polar mesospheric clouds (PMCs). By capturing simultaneous top and bottom views of the PMCs, these airborne images will both provide insight into the time evolution of PMCs, and into the micro-features of these clouds, from which gravity waves and other details of the clouds vertical structures may be obtained. These data may help us better understand the driving mechanisms of these clouds and ultimately those elements of global climatic change, which are believed to cause their expanding presence. The proposed imager will use a similar charged-coupled device and interface as that of the Aeronomy of Ice in the Mesosphere’s (AIM’s) Cloud Imager and Particle Size (CIPS) imager and will observe the clouds in both the visible spectra and in a near-ultraviolet spectrum closer to the sensitivity of the CIPS imager. The sensor is to be integrated aboard UTSIs Piper Navajo. Algorithms for satellite intercept trajectories and airborne imager positioning are developed for flight campaigns, scheduled for the 2007 Boreal Summer along a series of airstrips in both Northern Quebec and Alaska.

The purpose of this study was to investigate, under experimental conditions, the effect of a laboratory experience on self-acceptance and internal-external control with academically deficient college students as compared with Regular students.The ninety subjects in this study were all undergraduate students at Ball State University, Muncie, Indiana. The study was conducted during the spring of 1978.Two sections of the Career and Life Planning course, Counseling Psychology 110, were designated as control groups; and, two other sections were designated as experimental groups. One section of the control group sections contained Academic Opportunity Program students; and, one section contained regular students. The same was true for the experimental group. The experimental groups participated with a vital peer in six one hour laboratory sessions over a six week period. Each week's laboratory session consisted of an experiential exercise and a group discussion. The feedback by the subjects and vital peers utilized guidelines delineated by Brammer.The data collected for each subject was the total score obtained on the Personal Orientation Self-Acceptance Scale and Rotter's Internal-External Scale. Each subject was administered a pre-test and post-test of each instrument.The effects of the treatment were analyzed through the use of a 2 X 2 multivariate analysis of covariance. The pre-test scores were used as a covariate.An F-test was used to test the parallelism of regression hyperplanes. This test-examined the homogeneity of the mean factors; and the results indicated the groups were parallel. The implications for this test indicated that the results could be interpreted directly.Two null hypotheses were stated. The first null hypothesis stated that there would be no significant difference between the A.O.P. subjects and the Regular subjects on the P.O.I. (Sa) Scale. This hypothesis was not rejected at the .05 level. The second hypothesis stated that there would be no significant difference between the A.O.P. subjects and the Regular subjects on the I-E Scale. This hypothesis was not rejected at the .05 level. A significant multivariate F (F=4.43, P.<.05) did occur when comparing all of-the A.O.P. subjects scores and all of the Regular subjects' scores. The univariate F which had an effect on the multivariate F was the P.O.I. (Sa) Scale (F=7.42, P.<.01).It was concluded from this study that:this treatment, with this population, in this time frame and measured by the P.O.I. (Sa) Scale, did not produce significance between the Experimental and Control groups.2. this treatment, with this population, in this time frame and measured by the I-E Scale, did not produce significance between the Experimental and Control groups.3. A.O.P. and Regular subject groups in this study experienced an increased overall mean on the Post P.O.I. (Sa) Scale.4, based on the correlation matrix which was constructed, the P.O.I. (Sa) Scale and the I-E Scale were found to measure separate factors.The results of this study and subjective observations indicated several areas which may be worthy of further exploration.1. This study needs to be replicated where the time periods could be extended to an hour and one-half to provide more time for the individual laboratory experiences.It is recommended that two groups of subjects be used which are not enrolled in the Career and Life Planning class.3. Although the measurement instruments used in this study are frequently used in research, it might be advisable to replicate this study using a different measurement which may be more sensative.4. Since the purpose of this study was to establish a need for further research, this research might be geared towards creating an instrument that does evaluate the effects of a V.P. feedback process.5. A 12 hour marathon group may provide additional and different information than the six week laboratory experience.6. Board games similar to the Ungame and Lifestyle may be added to the laboratory experiences. The subjective responses indicated subject popularity which may influence self-acceptance and/or internal-external control.

A self-contained, portable, inertial and positional measurement system was developed and tested for an HGU-55 model fighter pilot helmet. The system, designated the Portable Helmet Instrumentation System (PHIS), demonstrated the recording of accelerations and rotational rates experienced by the human head in a flight environment. A compact, self-contained, “knee-board” sized computer recorded these accelerations and rotational rates during flight. The present research presents the results of a limited evaluation of this helmet-mounted instrumentation system flown in an Extra 300 fully aerobatic aircraft. The accuracy of the helmet-mounted, inertial head tracker system was compared to the aircraft-mounted referenced system. The ability of the Portable Helmet Instrumentation System to record position, orientation and inertial information in ground and flight conditions was evaluated. The capability of the Portable Helmet Instrumentation System to provide position, orientation and inertial information with sufficient fidelity was evaluated. The concepts demonstrated in this system are: 1) calibration of the inertial sensing element without external equipment 2) the use of differential inertial sensing equipment to remove the accelerations and rotational rates of a moving vehicle from the pilot’s head-tracking measurements 3) the determination of three-dimensional position and orientation from three corresponding points using a range sensor. The range sensor did not operate as planned. The helmet only managed to remain within the range sensor’s field of view for 37% of flight time. Vertical accelerations showed the greatest correlation when comparing helmet measurements to aircraft measurements. The PHIS operated well during level flight.
