Renewal of lapsed UK ATPL
I wondered if anyone knows the answer to this. A UK ATPL issued in around 2001, has now lapsed, and has not been exchanged for another other licence such as an EASA ATPL. The original license I am assuming was issued under CAP 54 rules. Can it be renewed without a certificate of test, IR renewal or medical, bearing in mind that is quite difficult to achieve under current COVID-19 lockdowns. Also is this licence valid for life, but with priviledges restrictled to say CPL or PPL as the pilot becomes older or the medical status is restricted or down graded.
