BACKGROUND Aircrew-aircraft compatibility is important in military aviation for flight safety. Anthropometric aircrew selection standards in RAFO were embedded from the selection standards of western defense forces as the aircrafts were imported from there. Henceforth efforts were made to fit local native aviators into aircrafts not initially designed for them. In view of this, this study was carried out to obtain the anthropometric data of Oman aircrew recruits and compare these with published western and eastern data with a hope to understand and highlight the aircrew-aircraft mismatch issues, if any.METHODS The anthropometric data of 2296 Omani recruits from 2003 to 2012 were collected and their statistical distribution of data was collated. Published data from the UK and Singapore were used to carry out the comparative distribution of five anthropometric dimensions.RESULTS Minimal differences were noted between Oman and Singaporean recruits whereas differences were most pronounced between Oman and Western populations (UK). Aircrew cadets from Oman, Singapore, and UK differed significantly in standing height. The UK cadets (M = 177.4 cm) showed the highest standing height followed by Oman cadets (M = 171.9cm), and then Singapore cadets (M = 168.5 cm).DISCUSSION This study has provided opportunities to recognize the discrepancies involved in selection of Middle Eastern aircrew for western cockpits. This adds impetus to the scope for application of military recruitment standards suitable to the native population in aiding the ideal man-machine interface. This approach shall consider national policy, the significant anthropometric trends of the general population, and the procured aircraft profile of the country.Al Wardi Y, Jeevarathinam S, Al Sabei S.

This study is a unique examination of significant outcomes in aviators with previous history of both AF and stroke.METHODS Pilots examined by the FAA between 2002 and 2012 who had had AF at some point during his or her medical history were reviewed, and those with an initial stroke or transient ischemic attack (TIA) during that time period were included in this study. All records were individually reviewed to determine stroke and AF history, medical certification history, and recurrent events. Variables collected included medical and behavior history, stroke type, gender, BMI, medication use, and any cardiovascular or neurological outcomes of interest. SKLB-D18 mouse Major recurrent events included stroke, TIA, cerebrovascular accident, death, or other major events. These factors were used to calculate CHA₂DS₂-VASc scores.RESULTS Of the 141 pilots selected for the study, 17.7% experienced a recurrent event. At 6 mo, the recurrent event rate was 5.0%; at 1 yr, 5.8%; at 3 yr 6.9%; and at 5 yr the recurrent event rate was 17.3%. No statistical difference between CHA₂DS₂-VASc scores was found as it pertained to number of recurrent events.DISCUSSION We found no significant factors predicting risk of recurrent event and lower recurrence rates in pilots than the general population. This suggests CHA₂DS₂-VASc scores are not appropriate risk stratification tools in an aviation population and more research is necessary to determine risk of recurrent events in aviators with atrial fibrillation.Tedford J, Skaggs V, Norris A, Sahiar F, Mathers C.
