Connex,
A few posts ago you asked if any of us can foresee problems with licensing. So far in the course of looking into this issue, I've come up with:
Possible demarcation both ATSA/ATSA and/or ATSA/ATCO
Handling of loss of license
Application of SCRATCOH?
Possible two tiers within the grade between licensed and unlicensed ATSAs - how will it be decided which tasks are licensed?
These are on top of the issues already mentioned in this thread such as the cost of running such a scheme, medical requirements, training, LCEs and the biggest one of all - ATCO opposition, (in spite of some encouraging comments on previous posts).
I'm still in favour.
