PREFLIGHT INSPECTION (Continued)
CABIN (Continued)
IF OAT IS AT OR ABOVE 15°C (59°F)
• With TKS Ice Protection System fluid temperatures
at or above 15°C (59°F) the fluid viscosity will
decrease, or become thinner, and may affect proper
fluid flow to parts of individual panels. With lower
fluid viscosity operating pressure may not be high
enough to cancel the red A-ICE PRESS LOW
annunciator.
• It is extremely important to visually inspect each TKS
panel for proper fluid flow across a portion of the
active area of each panel prior to flight into known or
forecast icing conditions.
At these higher temperatures TKS panels may not “Wet Out
or achieve 100% saturation” like they do at cooler
temperatures.
