A very swift service is available at the FCLD counter.
As mentioned there is a small form to complete, they need
at least one valid type rating (LST or LPC) within last 12 months.
The current cost is GBP 185.00, payable there and then.
If you get there early enough, i.e. 8.30 onwards you will be out well within 2 hours, usually quicker.
