The paper outlines failures of selected avionic electric power devices operated onboard of combat helicopters in Iraq and Afghanistan. While the authors were examining the electric power system of aircrafts in order to prolong their operation life they paid attention to numerous symptoms of wear demonstrated by some units of aircrafts. It was peculiar that such symptoms have never appeared during similar examinations of aircrafts operated in our country. By all accounts, the weird wear of components results from high intensity of flights and specific features of operating missions, but harsh climatic conditions seem to be the crucial factor. The authors believe that many of spotted failures experienced by electric power equipment may also happen to aircrafts operated in Poland but obviously, due to much lower intensity of operation and mild impact of environmental factors, such failures shall occur much later.

The authors focused their attention on two groups of electric devices and associated destructive factors:

1. Air-cooled electric rotary machines. Fine-grained sand sucked together with air leads to very quick abrasion of protective paint coatings inside the machines. Not frequent but intense rainfalls are the reason for appearance of corrosion pits that lead to such effects as increase of pole shoe volumes. This, in turn, results in shearing of winding insulations with breakdowns (shorts) to ground and, as a final consequence, considerable drop of power demonstrated by an electric machine.

2. Contactors and electromagnets, which are allegedly tight. However, dust penetrates anyway via microfissures and disables operation of moving parts.

and turned to sprint again toward cone 3. The participant circled cone 3 and returned to the finish line. The participant was not allowed to touch the cones or place their hands on the floor when making turns or circling the final cone. All participants executed two attempts with cone 3 on the left and two attempts with the cone on the right side. Statistical Analysis All data were presented in the form of means ± standard deviations. Comparisons between the right and left sides were examined by paired t-tests.

The first two subscales address the cognitive aspect of empathic behaviour/attitude ( 23 ). The validity and reliability of the JSE were evaluated ( 11 , 23 , 24 ); it has been translated into 53 languages and used in more than 80 countries worldwide ( 26 ). The only Slovenian study so far used the JSE in medical students (JSE-S) and confirmed the three-factor structure of the 18-item scale ( 13 ). For our study, the JSE was translated into Slovenian

Immediately thereafter, subjects were asked to take off their shoes and then were seated on the dynamometer chair, with the seat back at an angle of 75° (0° = full hip extension in the lying position) and the proximal part of the calves touching the frontal edge of the seat. In order to minimize extraneous body movements, the shoulders, the chest, the hip and the right femur of the subjects were firmly secured to the chair by means of adjustable straps and belts. In addition, subjects were told to use the

tests were performed in athletes’ practice sites, before their training sessions. It was ensured that the floor on which the tests were conducted were cleaned and dried to prevent accidental slips. Sports shoes commonly used in practice sessions were used to perform the tests. Before testing, all athletes performed typical warm-up activities in order to not hinder their performances. Firstly, participants performed the Badcamp agility test ( Loureiro Jr and de Freitas, 2016 ) and afterwards they performed the SRAT from EUROFIT ( Adam et al., 1988 ). A five-minute rest
