ATPL exams without first class medical certificate
I currently hold a second class medical certificate, but I have been assured by my country's authority's doctors that I do meet the standards for the issue of a first class medical certificate the day I obtained my second class medical certificate.
I am thinking of undergoing eye surgery as I have been discussing this option recently with my ophthalmologist. This would take some time because of the time lapse requested by the UK CAA to be assessed after eye surgery -- it should be around 3 months for LASIK.
In the meanwhile, am I allowed to attend an ATPL course and sit the exams without a valid medical certificate at all and just with an EASA PPL?
