Embry Riddle Aeronautical University researchers are asking INSTRUMENT-rated PRIVATE pilots and AIRLINE pilots to complete a 2-5 minute questionnaire (https://www.surveymonkey.com/r/GK3ZD3B) as to the amount/type of NON-revenue flying in light aircraft undertaken by them. Such information, combined with light aircraft accident data, could lead to improved general aviation safety for either, or both, groups of pilots.
