With the CG in the forward position the elevator may not be able to
produce a sufficiently high angle of attack to completely stall the wings
with positive flap settings. In this case, the stall speeds are defined by
the minimum achievable speed for the specific flap setting.
The stall speed in all flap settings is increased by approximately 5 km/h
with the airbrakes extended. The landing gear position has no
measurable influence on the stall speeds.
Take-off performance
Not applicable to a self-sustaining aircraft.

Turbulators
On the lower surface of the flaperons there is a line of blow holes
supplying air by NACA ducts. It is necessary to keep these holes and
ducts clean for optimum performance. The blow holes force the boundary
layer transition from laminar flow to turbulent flow in flap setting 1 and 2.
If the boundary layer control is not working properly, a whistling sound
can be heard when changing to flap setting 1 and 2.
WARNING:
Turbulator tape is fitted to the tailplane and rudder and
is essential for both the performance and control of the
aircraft. Flight without tailplane turbulators is not allowed
as it might result in a reduction in pitch authority. See the
JS-MD 3 Aircraft Maintenance Manual for the correct
location of the turbulator tape.
