LIMITATIONS
ENVIRONMENTAL CONDITIONS
Some icing conditions not defined in 14 CFR Part 25 Appendix C have
the potential of producing hazardous ice accumulations, which (1)
exceed the capabilities of the airplane's ice protection equipment, and/
or (2) create unacceptable airplane performance and stall speed
increase. Pilots must be prepared to divert the flight promptly if
hazardous ice accumulations occur. Inadvertent operation in these
conditions may be detected by:
1. Unusually extensive ice is accreted on the airframe in areas not
normally observed to collect ice.
2. Accumulation of ice on the upper or lower surface of the wing aft
of the protected area.
3. Heavy ice accumulations on the windshield, or when ice forms
aft of the curved sections on the windshield.
4. Ice forms aft of the protected surfaces of the wing struts.
If these conditions are encountered, the pilot must take immediate
actions to exit these conditions.
Continued flight in icing conditions is prohibited after encountering one
or more of the following with the TKS Ice Protection System fully
functional and operating:
1. Airspeed in level flight at constant power decreases by 10 KIAS
using Maximum Cruise Power.
2. MEA or MOCA (if applicable) on current leg falls into Area "C" of
Figure S1-1, Enroute Tool For Exiting Icing, located in the
Performance section of this supplement.
Exit strategies must be determined during preflight planning.
