I think this is yet another example of our dysfunctional CAA. Medical Dept have recently been observed to send out
SRG 1205 A quite ridiculous form which shows they clearly have no idea what a CFI is, i.e. an appointment, not a qualification! In any event the form should only be used when there has been a medical hearing issue.
I am puzzled as to what a stammer has to do with NATS?
