AEROTOW. The ASK-21 flies well on aerotow. Typical aerotow speed is 60 knots.
It is “slick” so rope slack may occur in rough air. Use the “yaw away from the rope” or ½
airbrake method to gently remove the slack. Release if slack is excessive.
Fly just above the towplane wake.
Match the bank of the towplane and keep the towplane just above the horizon.
PATTERN PLANNING.
Keep the airspeed at no more than 55 knots, and check the variometer to see if you are
flying in lift or sink. This is essential. 5 Knots down works well on the downwind leg and
early base leg. “55 and 5.” Glance at the trends of the airspeed and vario. Check your
angles to the aim point, touchdown and stop points.
Use the “TLAR” (“That Looks About Right”) or my “TLAW” (“That Looks About Wrong!”)
method to judge your pattern. Increase your sink with the airbrakes on final approach to fly
through the “mail slot” over the end of the runway with ¾ airbrakes.
ASK-21 on final approach, before “roundout” or flare to land on main and tailwheel.
Use about ¾ Airbrake, 55 knots max. through the “mail slot” at the end of the runway.
