Whirlybird has it right, the weather has been really difficult recently for solo circuits. Not necessarily the cloud base but it has been very cross windy which is no good for solo circuits but fine for dual navs. We've also done steep turns, PFLs and diversions.
Im flying everday this week (weather permitting) so Ill let you know how I get on!!
Blueskis I am flying a high wing (c152).
Thanks for your advice
