It is pleasant to fly aerobatics with PIK-20D, but the control forces are light. It is strongly recommended that before starting flying aerobatics with a PIK-20D one has got aerobatic training on a two-seater sailplane and one has demonstrated for an aerobatic gliding instructor observing on the ground, the ability to pass on a two-seater sailplane the exam of advanced aerobatics consisting of the following maneuvers:
- half roll to inverted flight
- 180 degree inverted turn
- half roll to normal flight
- stall turn
- looping
- slow roll
- half Cuban eight
- half of an inverted Cuban eight
- Immelmann
or an equivalent level sequence of maneuvers.
