MAXIMUM AVAILABLE SYSTEM OPERATING TIME
With the ice protection system uid tank full, the following maximum
operating times are available:
NORM Flow Duration
................................................. 160 Minutes (6 GPH)
HIGH Flow Duration
................................................... 80 Minutes (12 GPH)
MAX Flow Duration
.................................................... 40 Minutes (24 GPH)
Continuous operation of the aircraft in conditions that promote ice
accumulation is prohibited.
VISUAL/TACTILE CHECK
Takeoff is prohibited with any frost, ice, snow, or slush adhering to the wings,
tail, control surfaces, propeller blades, or engine inlet.
To assure the absence of frost, a visual and tactile check of the wing
leading edge and upper surface is required if the OAT is below 10°C. This
check shall be performed in accordance with the “Normal Procedures”
section of this supplement. During ground icing conditions, takeoff must
be accomplished within 5 minutes of completing the inspection, unless the
airplane is operated in accordance with 14 CFR 135.227(b)(3).
Each upper surface of the wing must be inspected for the condition
and presence of vortex generators. Each wing must have all 14 vortex
generators installed on the upper surface.
WINDSHIELD PUMP
The windshield pump is rated for intermittent use only. Continuous operation
may damage the pump. Do not operate the windshield pump longer than 10
seconds. Allow 10 seconds between operations.
INERTIAL SEPARATOR
If the inertial separator is set to BYPASS at any point due to suspected or
actual icing conditions, do not return it to the NORMAL position until the
inertial separator door has been visually inspected and veried free of ice.
AUTOPILOT
Autopilot operation is prohibited when operating in icing conditions that are
outside the 14 CFR 25, Appendix C (for IAC AR certied airplanes, IAC
AR Aviation Regulations Part 25, Appendix C) dened conditions in the
“Environmental Conditions” section of this supplement.
CAUTION: Use of the windshield ice protection system will reduce the
maximum available operating time of the system.
WARNING: Use of the Windshield Ice Protection System may obstruct
view due to residual ice protection uid on the windshield. Do not operate
the Windshield Ice Protection System within 30 seconds of landing.
