Many thanks for your replies. I have had some really interesting (although not unexpected) responses but the intensity of feelings regarding FTL's is quite marked.
I am aware that it may not be looked on too keenly by the CAA but I am determined that they will get a copy of the results as will BALPA and any other interested parties. At least it will be backed up by solid research rather than just anecdotal evidence so it can't be ignored quite so easily. The project has been accepted, in principle for publication by a peer review occupational health journal and will also be offered to flying mgazines at the appropriate time.
I am now collating the results with the study completed by August so will be able to post results Sept.
Thanks for encouragement and for everyone's help who has contributed.
Laurie
