The new self declaration without GP countersignture, is in principle a good thing, but for the likes of us who have had cardiac surgery and subsequent medication, it is potentially restrictive, and at odds with the DVLA Group 1 medical requirement.
At least with the previous declaration, your GP with knowledge of your history could use his or her common sense, as I would suggest that pilots with a condition that is monitored and appropriately medicated, are arguably less likely to suffer incapacitation than an undiagnosed one.
Being forced now to go for LAPL certificate, with possible cost implications, will cause many to think twice, myself included, before heading off to the nearest AME.
