Just getting back in the saddle after 15 years out, had an hour with the CFI and he adjudged me as needing 4-5 hours to get back up to scratch. I was surprised about how much came back to me, but then I had been thinking about it for a while, had done a lot of viewing of some of the really good YouTube content out there, and did some of the ol' bath and car seat 'piloting' - so my head was getting into the right space before I got in the cockpit. Was still shocked at how much of a blast I had, what with moving from spam cans to three-axis microlights and an instructor very keen to demonstrate the aircraft's capabilities!
