I'm slightly worried that several people seem not to have covered spiral descent/dive recoveries during EASA PPL training though.
Not speaking for the other posters, but I deliberately did not include any techniques for spin/spiral dive recovery in my post, since the scenario of the OP is the base to final turn.
If you end up in a spin in that scenario, there's no way you'll recover in time. If you end up in a spiral dive in that scenario, you may be able to recover if you're completely on the ball. But IMHO prevention is the only real solution for this scenario.
