There seem to be some subtle differences between the online survey and the magazine questionnaire. Is this in fact the case?
The magazine article is a flavour of the questionnaire to generate publicity. The survey is the survey and that is how the data will be collected and modelled.
We are asking the CAA to circulate the information, we will be running regular articles in the various magazines and forums.
We can't collect pilots licence numbers etc without going down the data protection route which then increases the complexity and costs. We can filter duplicates even on common IP. You will find that if you go back again your answers from the last session are already completed.
