Fifty general aviation pilots (average age 49; range 40-73) completed a questionnaire concerning cockpit visual problems. The results of the questionnaire indicated that proper interpretation of the airspeed indicator and the altimeter required the best visual acuity (48 and 39 percent of the respondents respectively). However, 33 percent reported
