“…With HWDs, flight data can be displayed in three-dimensional stereo to declutter the information presented [ 3 ]. HWDs have many advantages over traditional displays, such as increasing situation awareness, greatly reducing the pilot’s workload and improving the ease of mobility [ 4 , 5 ]. As performance indicators and the targeting system are integrated in the HWDs, pilots are able to capture, track and launch missiles to targets on the interface, which enables them to gain an advantage in air battle [ 6 , 7 ].…”

Head-worn displays (HWDs) as timely condition monitoring are increasingly used in aviation. However, interface design characteristics that mainly affect HWD use have not been fully investigated. The aim of this study was to examine the effects of several important interface design characteristics (i.e., the distance between calibration lines and the layouts of vertical and horizontal scale belts) on task performance and user preference between different conditions of display, i.e., HWD or head-up display (HUD). Thirty participants joined an experiment in which they performed flight tasks. In the experiment, the calibration lines’ distance was set to three different levels (7, 9 and 11 mrad), and the scale belt layouts included horizontal and vertical scale belt layouts. The scale belts were set as follows: the original vertical scale belt width was set as L, and the horizontal scale belt height as H. The three layouts of the vertical calibration scale belt used were 3/4H, H and 3H/2. Three layouts of horizontal calibration scale belts were selected as 3L/4, L and 3L/2. The results indicated that participants did better with the HWD compared to the HUD. Both layouts of vertical and horizontal scale belts yielded significant effects on the users’ task performance and preference. Users showed the best task performance while the vertical calibration scale belts were set as H and horizontal calibration scale belts were set as L, and users generally preferred interface design characteristics that could yield an optimal performance. These findings could facilitate the optimal design of usable head-worn-display technology.

BACKGROUND: Medical selection criteria for Israeli Air Force (IAF) Flight Academy candidates are strict due to the extreme physiological stressors during military flight. In various air forces the causes for medical disqualification of Flight Academy candidates are different, mainly due to differences in the selection process and criteria. In the present study, we examined the medical conditions leading to disqualification of candidates for the IAF Flight Academy.METHODS: We reviewed the medical records of 3281 military Flight Academy candidates who underwent medical evaluation in the IAF Aeromedical Center between June 2016 and March 2018. For each disqualified candidate, we examined the cause or causes for disqualification divided into categories.RESULTS: Out of 3281 Flight Academy candidates, 519 candidates (15.8%) were disqualified. The most prevalent cause for disqualification were ophthalmological conditions, which constituted more than half of the disqualifications (55.0%). Among the ophthalmological conditions, nonsatisfactory visual acuity constituted more than half (57.4%). The following most prevalent causes were asthma (7.9%), allergic rhinitis (7.3%), renal and urinary conditions, and otolaryngologic conditions (5.2% each).DISCUSSION: The leading cause for disqualification of Flight Academy candidates was ophthalmological conditions, similar to other air forces. Our findings warrant an ongoing review of criteria for disqualification.Groner O, Frenkel-Nir Y, Erlich-Shoham Y, Shoval G, Gordon B. Medically disqualifying conditions among aircrew candidates.
