GARMIN G1000
PERFORMANCE
Airplane performance and stall speeds without ice accretion are
unchanged with installation of the TKS Ice Protection System. Use the
performance charts located in the POH/AFM, Section 5, for
performance calculations.
If the TKS Ice Protection System is operating normally and
preventing ice from accreting on the airframe protected
areas and propeller, normal performance will only degrade
slightly. If ice is allowed to accrete on the airframe protected
areas, however, significant climb and cruise performance
degradation, range reduction, as well as buffet and stall
speed increase can be expected. Ice accretion on the
airframe protected areas will cause noticeable performance
losses.
NORMAL AND BALKED LANDING RATE OF CLIMB
Residual ice on unprotected airplane surfaces will cause a loss in rate
of climb. Additional accumulation of ice on the airplane will result in
significant loss in normal rate of climb.
