S-turn

S-turns
The S-turn is a series of 180-degree turns made across some straight line on the ground, such as a road, fence line, or railroad, which lies at approximately 90 degrees to the direction of the wind.

 


S-Turns
The two downwind and two upwind turns of the S-turn combine the four quadrants of the left and right turns about a point. The technique calls for the wings to be momentarily level at the moment of crossing the reference line.

S-turn - Course flown by student pilot from point A to point B.
Safety Belt - Drink taken by instructor before flying with difficult student.
Short-field Takeoff - A takeoff from any field less than 10,000 feet long.

Scrunch your head against the left sidewall and you have a semblance of visibility straight ahead, but S-turns are still mandatory because of the deck angle.

Slipping or shallow s-turns can be done as well. To ease airspeed control trim the aircraft for its final approach speed.

For gross errors, S-turns or zero (or negative) airspeed may be required. One final rule I have is never do a 360 degree turn. You lose track of your approach angle for too long.
