Provided that you have had the appropriate training for VP, RG and 140+KIAS (if appropriate), then you can indeed fly a single seat 1300lb 200 HP CS prop aircraft around in the UK in VMC using a SSEA Class Rating. ENJOY!!
You won't even need to complete the 1 hr of training flying with an authorised instructor if you don't wish to carry passengers in any SSEA - and your SSEA Class Rating will then be restricted to SSEAs fitted with a single seat!
And before any idiots start, 'single seat' does
not include a C152 flown solo!
