so any suggestion about to improve this survey??????
You say it is a survey in GA, yet many of the questions seem to assume employment as a pilot. To be paid as a pilot you need to be CPL or higher. There are a lot of PPL's in GA that are not employed as pilots (like me). I gave up on the survey when I encountered many questions about shifts, rest times etc to which there was no appropriate answer for a PPL hobby flyer.
To improve the survey it either needs to provide answer options appropriate for PPLs, or else exclude PPLs from the survey and direct it at CPLs and higher.
