Abstract The paper presents the results of the integrity of Galileo satellite positioning for the area of the military aerodrome in Dęblin. The integrity parameters of the Galileo satellite positioning have been determined for en-route navigation and the precision approach. To study the integrity parameter, Galileo satellite measurements from the GNSS reference station located in the area of the Aviation Department of the Polish Air Force University, located near EPDE military aerodrome in Dęblin, were used. In particular, in the research, to determine the integrity parameter, the mean errors of the determined coordinates of GNSS reference station in the BLh ellipsoid frame were used. The research test was carried out on 11 January,2019. The authors of the work studied the parameter of the integrity of Galileo positioning used HPL and VPL protection levels.

ABSTRACT Objective Dealing with the COVID-19 outbreak required a rapid adjustment to an unfamiliar and unique situation. The current study aimed to identify the challenges faced by Israeli Air Force (IAF) career personnel. Method A survey was conducted on 550 participants during the first wave of the COVID-19 outbreak. The participants completed a questionnaire that dealt with unique challenges (personal, family, and command). Results Of 550 respondents, 54% reported low mood and irritability, 44% reported a constant feeling of anxiety, and 29% reported having sleep problems. Most of them (66%) were mainly concerned about infecting their family. The shift from normal work conditions to an unfamiliar capsule configuration concerned 58% of respondents. Functional continuity concerned 55% of respondents. Managing subordinates concerned 50% of the participants. Of the three types of challenges analyzed (personal, family, and command), the command challenge was the only one where the personal variables (military role, rank, and marital status) made no difference. Finally, about 30% of all respondents reported they needed professional support in dealing with the new circumstances. Their preferred platform was an easily accessible hotline. Conclusions Life under the COVID-19 threat increased stress factors in the military career population. While reporting greater challenges and higher levels of stress, most of the respondents preferred a brief, focused consultation adjusted to the situation rather than conventional psychological help. The command challenge and the perceived responsibility stood above and beyond all variables examined in the present study.

Speed And Accuracy

A legibility study was performed to investigate the effects of scale factors, graduation marks, orientation of scales, and reading conditions on the speed and accuracy of reading moving-tape instruments. Each of 150 Air Force Officers made 150 self-paced readings from slides of hand drawn tape instruments. Error was expressed as the magnitude of deviation of a subjects' verbal response from the set scale value. An analysis of variance was performed on the mean error scores, standard deviations of error, mean reaction times, and standard deviations of reaction times. The results clearly favored the 1 7/8 inch scale factor over the 1 3/8 inch and the 2 3/8 scale factor. The use of 9 graduation marks was superior to either 0, 1, 3, or 4 graduation marks. Reading conditions had little effect on performance. Horizontal scales were read more rapidly but no more accurately than vertical scales.

Abstract. The article is devoted to the special features of the military pilots training and the problem of forming their readiness for professional interaction when using the joint airspace with other countries. The article deals with the specifics of a military pilot’s job and the specificity of military pilots training at the Kharkov National Air Force University, in particular, at the Aviation English Department. The components of military pilots' readiness for professional interaction, criteria and levels of such readiness are determined. It is emphasized that readiness for professional interaction in the common airspace is a necessary requirement today in view of the active development of cooperation and formation of interoperability between Ukrainian aviation and foreign partners. Such readiness is impossible without a proper level of military pilots’ foreign language command. Successful formation of future aviation pilots' readiness for professional interaction while using common airspace requires the modernization of cadets training and the use of innovative pedagogical technologies that promote personality development and increase the training effectiveness.

ABSTRACT Background Decreases in routine healthcare practices have been shown to occur during disasters. However, research regarding the impacts of natural disasters, pandemics, or military conflicts on emergency medical services (EMS) is scarce. Objectives This study assessed the impact of a military conflict versus the coronavirus disease 2019 (COVID-19) pandemic on a national EMS organization in terms of responses to overall daily emergencies, medical illnesses, motor vehicle collisions, and other injuries. Methods This retrospective comparative cohort study assessed daily routine emergency ambulance calls to Magen David Adom (MDA), Israel’s national EMS organization. This included overall emergency calls as well as those related to medical illnesses, motor vehicle collisions (MVCs), and other injuries. All data were obtained from the MDA command and control database. During the military conflict Operation Protective Edge (2014), the civilian population was subjected to intensive rocket attacks for 24 days, followed by 26 days of a progressive withdrawal of operations and then to a post-conflict period. During the first wave of the COVID-19 pandemic (March-April 2020), the population was subjected to 32 days of total lockdown, followed by 27 days of progressive relief of confinement, and then to a post-lockdown period. Results The total number of emergency calls in this study was 330,430. During the conflict, the mean number of daily calls decreased, followed by an increase during Relief and Post-Conflict with higher values in Post-Conflict than in Pre-Conflict. During the COVID-19 pandemic, there was a decrease in the mean daily number of calls during Lockdown. It remained low during Relief and increased during Post-Lockdown. However, it remained lower in Post-Lockdown than during Pre-Lockdown. Calls related to medical illnesses decreased during the conflict and during the lockdown. The post-conflict period was characterized by a similar baseline call magnitude but not during the post-lockdown period. Decreases in calls for MVC and other injuries were significant during the lockdown but not during the military conflict. Post-lockdown was accompanied by return to baseline call volumes for MVC, whereas calls for other injuries increased above baseline both after the lockdown and military conflict. Conclusion This study shows decreasing trends in routine daily calls for EMS during both Operation Protective Edge and COVID-19. However, different patterns of needs for EMS were evidenced for medical illnesses, MVC, or calls concerning other injuries. These results are instrumental for managing the operational demands of EMS during military conflicts and pandemics.

The Impact

BACKGROUND: Graves’ Disease (GD) is a common cause of hyperthyroidism. Although definitive treatment with radioactive iodine (RAI) is preferred for military aircrew, there are cultural and individual differences in receptivity toward RAI, and clinical guidelines that recommend antithyroid drugs (ATD) as the first line therapy. We examined a case series of Republic of Singapore Air Force (RSAF) aviators with GD treated with ATD and the impact of their condition on aeromedical disposition.CASE SERIES: All RSAF aircrew diagnosed with GD and treated with ATD over a 15-yr period were retrospectively identified and analyzed to determine the impact on their fitness for flying duties. The mean age of the 13 aircrew was 33 ± 7.1 yr (range, 25–47 yr), with 11 (84.6%) being males. There were 10 (76.9%) who had ATD as the only treatment while 3 (23.1%) were initially treated with ATD but subsequently underwent RAI or surgery. Of the 10 treated with only ATD, 3 (30.0%) were returned to restricted flying, 6 (60.0%) were returned to unrestricted flying, and 1 (10.0%) is still undergoing ATD titration. There were 10 (76.9%) aircrew who were returned to some form of flying duties while on low doses of ATD.DISCUSSION: This case series suggests that ATD is a viable treatment modality in the aeromedical management of military aviators with GD and it is possible to return military aircrew on a stable maintenance dose of ATD to flying duties. A framework is proposed to support the aeromedical decision-making process for military aircrew in the treatment of GD.Loh EH-T, Soh FW, See B, Tan BBC.

Focused on the period of atmospheric (above-ground) nuclear weapons testing in the continental United States, from 1945 to 1963, this chapter, written by Susan Courtney, does two things. First, it describes some of the basic conditions and infrastructure that shaped the proliferation of films of nuclear weapons tests, including the U.S. government’s secret military film studio dedicated to this work in the hills above Los Angeles, known as Lookout Mountain Air Force Station or Lookout Mountain Laboratory. Second, it turns to the representational legacy that resulted, which was by no means limited to films made by or for the military. More specifically, it considers how footage of atomic tests in New Mexico and at the Nevada Test Site helped to shape the filmic record of nuclear weapons—and popular cultural memory—by framing the bomb in the desert West, arguably the screen space of American exceptionalism.

The largest air transport at present operating on air routes is the Douglas Globemaster which is able to lift up to 130 passengers and a considerable load of mail and freight. Experience of flying Globemasters many times on the military route between Seoul City Airport (Korea) and Tashekawa Air Force Base (near Tokyo) suggests the following observations. They may be of value to those aircraft manufacturers in Great Britain now building 130/150 seater jet air liners and to British Overseas Airways Corporation and other air lines who will be concerned with operating them, possibly by 1960.
