When you don't KNOW what to do, DO NOTHING! Even the Air France plunge into the Atlantic was caused by the pilots doing the wrong thing, same with the Colgan disaster.
Typical stall and spin approach scenario, ...."I pulled back on the stick, and the nose wouldn't come up! The elevator didn't seem to work, so I pulled harder....."
While being flipped on approach by wake turbulence does call for immediate and expert recovery, this doesn't happen a lot.....but if your aircraft is properly trimmed and was flying just fine a few seconds before things went pearshaped, let go of everything and pray!
History relates, in the early days, the first pilot to recover from a spin decided he was going to die anyhow, and stopped trying to bring the nose up from what he thought was a dive.....
