CY&B:
Would you ask your tame fountain how he/she deals with item 5.1 (RTO) here:
http://www.caa.co.uk/docs/33/FORSRG1157.pdf
I confess that I ask candidates about RTO but don't test, despite it being listed as a mandatory test item. IMHO testing RTO would add cost/risk/stress for no benefit - but I'm willing to be convinced otherwise.
