. Sample risk assessment matrix from AFPAM 90-803. 19 USAF Airworthiness Bulletin (AWB) 150B echoes the approach of separately identifying severity and probability, and using a risk matrix to determine an overall risk level. 17 AWB-150B establishes specific definitions for four severity categories and six probability ranges (though one probability category is zero, through elimination of risk), and integrates them into four overall risk levels using a risk matrix ( Fig. 2 ): high, serious, medium, and low. AWB-150B enacts AFI 62-601, which

Fig. 2.; U.S. Air Force (USAF) airworthiness risk assessment matrix. 21 The USAF Airworthiness Bulletin defines specific probability/frequency levels, as well as descriptions for each of four severity categories. The product of probability/frequency yields a risk; these risks are grouped into one of four risk assessment codes (RACs).

Equipment). 1 , 8 The flight simulator had also been used for pilot training and some airworthiness compliance activities and technology research. The checklist, quick reference handbook, and configuration documents were provided to the pilots during the experiment. Dual HUDs, manufactured by Thales Group and certified by Airbus in early 2015, were equipped in both pilots’ positions in the flight simulator with the display resolution of 1280 dpi × 1024 dpi, as in Fig. 1 . The eye position of the HUDs coincided with cockpit eye position. The size of the eye box, the

Fig. 4.; Legacy disposition recommendation vs. AMRAAM disposition recommendation. The diagonal cells from top left to bottom right are concordant (white boxes), where the AMRAAM and legacy dispositions were the same. The AMRAAM disposition was more restrictive for cells above this diagonal line (medium gray), and less restrictive for cells below the line (light gray). Percentages are expressed as the cell number divided by the total legacy dispositions for a given row. *Both cases were impacted by a policy change. The AMRAAM and legacy dispositions were in accordance with aeromedical policy at the time of review; the policy changed in between legacy and AMRAAM dispositions. †The legacy disposition was not in accordance with aeromedical policy at the time of the legacy disposition recommendation. ‡Compared to the legacy disposition, one restricted waiver was less restrictive with the AMRAAM disposition, and one restricted waiver was more restrictive with the AMRAAM disposition.
