S-turns are handy when you've been cut up on final. Sideslips are handy when you've cut somebody else up on (long) final. Both should be taught a lot more than they are.
....and how does that, and any of this S turn business, comply with the requirement for all turns in the circuit to be in the same direction as that set by other aircraft*? And surely good airmanship dictates that that if you cannot continue the approach safely you go around.
