Limitations
Section 2
Model G58
2-15
Ground use of windshield heat is limited to 10 minutes at a
time.
Sustained flight in icing conditions with flaps extended is pro-
hibited except for approach and landings.
LIMITATIONS WHEN ENCOUNTERING SEVERE
ICING CONDITIONS (Required By FAA AD 98-
04-24)
Severe icing may result from environmental
conditions outside of those for which the
airplane is certificated. Flight in freezing
rain, freezing drizzle, or mixed icing condi-
tions (supercooled liquid water and ice
crystals) may result in ice build-up on pro-
tected surfaces exceeding the capability of
the ice protection system, or may result in
ice forming aft of the protected surfaces.
This ice may not be shed using the ice pro-
tection systems, and may seriously
degrade the performance and controllability
of the airplane.
1. During flight, severe icing conditions that exceed those
for which the airplane is certificated shall be determined
by the following visual cues. If one or more of these
visual cues exists, immediately request priority handling
from Air Traffic Control to facilitate a route or an altitude
change to exit the icing conditions.
a. Unusually extensive ice accumulation on the airframe
and windshield in areas not normally observed to col-
lect ice.
b. Accumulation of ice on the upper surface of the wing,
aft of the protected area.
