9.4-5 PERFORMANCE

Airplane performance and stall speeds without ice accumulation are
essentially unchanged with the installation of the TKS Ice Protection System.
Significant climb and cruise performance degradation, range reduction, and
stall speed increase can be expected if ice accumulates on the airframe.
Residual ice on the protected areas and ice accumulation on the unprotected
areas of the airplane can cause noticeable performance losses and stall
speed increases even with the Ice Protection System operating.

N OTE S : Maximum altitude loss during wings level stall is approximately
500 feet. KIAS values are approximate and may not be accurate at the
stall. The following stall speeds are with approximately 3 inches of ice
build-up on the unprotected portions of the wing leading edges.
