RV-12iS Flight Training Supplement 11-2
STALLS, POWER-OFF
A pilot who is proficient and practiced in stalls is able to identify and take immediate and appropriate corrective
action if/when an inadvertent stall occurs.
Suggested exercise procedure:
Reduce power to idle and maintain wings-level, coordinated flight while increasing nose-up pitch attitude to
maintain target altitude until the aircraft stalls.
Stall break will typically be noted by the nose pitching down abruptly and potentially rolling right or left up to 15°.
While approaching the stall, maintain wings-level using rudder only, keeping the ailerons neutral. Upon stall break,
release control stick back pressure and increase engine power. Allow the aircraft to accelerate to 60 KIAS and re-
establish wings-level climbing flight.
Establish 30° bank turn to the right and repeat above exercise.
Establish 30° bank turn to the left and repeat above exercise.
Lower flaps to ½ deflection and repeat exercises listed above.
Lower flaps to full deflection and repeat exercises listed above.
STALLS, POWER-ON
Practicing power-on stalls offers the same benefits as practicing power-off stalls but exposes the pilot to more
extreme attitudes and builds the pilot's proficiency at using rudder to counteract p-factor.
Suggested exercise procedure:
Establish a full power, wings level climb at 65 KIAS. Increase nose-up pitch attitude by approximately 15° and
maintain that attitude as airspeed decays to the stall.
Stall will be noted by the nose pitching-down abruptly and potentially rolling right or left up to 15°.
While approaching the stall, maintain wings level using rudder only while keeping the ailerons neutral. Upon stall,
release stick back pressure and re-establish wings-level climbing flight at target airspeed.
Establish 30° bank turn to the right and repeat above exercise.
Establish 30° bank turn to the left and repeat above exercise.
Lower flaps to ½ deflection and repeat exercises listed above.
TURNS, STEEP TURNS
Continuous turns of 360° (or more) are good to practice because it familiarizes the pilot with the sight picture of
being banked at 45° or more for a period of time long enough to complete a full turn. The sight picture in a side-by-
side aircraft is different for a turn to the left versus a turn to the right. Practicing turns also exposes the pilot to the
physical sensation of additional acceleration and helps develop skills related to maintaining directional orientation
during a period of rapid heading change. Steep turns expose the pilot to the additional pitch and power adjustments
required to overcome the loss of vertical lift associated with a steep turn and the increased loading.
Suggested exercise procedure:
Point the nose of the aircraft at a prominent point on the horizon to use for reference. Establish power for cruise
flight at maneuvering speed (V
a
) and trim for level flight.
Note nose position relative to horizon.
Roll into a 45° bank left turn and while banking through 30° increase stabilator control back pressure slightly to
maintain the nose close to the previously noted position relative to the horizon.
Maintain the bank angle and altitude, and continue the turn for a full 360°, completing the turn with the nose pointed
exactly at the pre-selected reference point.
Strive to maintain constant airspeed throughout the turn and when airspeed increases above V
a
. reduce the
amount of bank before attempting to increase pitch.
Maintain attitude by visual reference to the horizon with only very quick glances at the EFIS to verify consistent
altitude.
