Licence Renewal
A strange thing for everyone is that while the need for revalidation is 24 months (every two years) the need to renew the licence is 60 months (five years) and this has the effect of the pilot being required to renew their licence half way between the second and third revalidation.
I suspect that there are many pilots who are unwittingly flying with current validations but with expired licences! Synchronisation would be helpful.
