§ 125.221 Icing conditions: Operating
limitations.
(a) No pilot may take off an airplane
that has frost, ice, or snow adhering to
any propeller, windshield, stabilizing
or control surface; to a powerplant in-
stallation; or to an airspeed, altimeter,
rate of climb, flight attitude instru-
ment system, or wing, except that
takeoffs may be made with frost under
the wing in the area of the fuel tanks
if authorized by the FAA.
(b) No certificate holder may author-
ize an airplane to take off and no pilot
may take off an airplane any time con-
ditions are such that frost, ice, or snow
may reasonably be expected to adhere
to the airplane unless the pilot has
completed the testing required under
§ 125.287(a)(9) and unless one of the fol-
lowing requirements is met:
(1) A pretakeoff contamination
check, that has been established by the
certificate holder and approved by the
Administrator for the specific airplane
type, has been completed within 5 min-
utes prior to beginning takeoff. A pre-
takeoff contamination check is a check
to make sure the wings and control
surfaces are free of frost, ice, or snow.
(2) The certificate holder has an ap-
proved alternative procedure and under
that procedure the airplane is deter-
mined to be free of frost, ice, or snow.
(3) The certificate holder has an ap-
proved deicing/anti-icing program that
complies with § 121.629(c) of this chap-
ter and the takeoff complies with that
program.
(c) No pilot may fly under IFR into
known or forecast light or moderate
icing conditions, or under VFR into
known light or moderate icing condi-
tions, unless—
(1) The aircraft has functioning deic-
ing or anti-icing equipment protecting
each propeller, windshield, wing, stabi-
lizing or control surface, and each air-
speed, altimeter, rate of climb, or
flight attitude instrument system;
(2) The airplane has ice protection
provisions that meet appendix C of this
part; or
(3) The airplane meets transport cat-
egory airplane type certification provi-
sions, including the requirements for
certification for flight in icing condi-
tions.
(d) Except for an airplane that has
ice protection provisions that meet ap-
pendix C of this part or those for trans-
port category airplane type certifi-
cation, no pilot may fly an airplane
into known or forecast severe icing
conditions.
(e) If current weather reports and
briefing information relied upon by the
pilot in command indicate that the
forecast icing condition that would
otherwise prohibit the flight will not
be encountered during the flight be-
cause of changed weather conditions
since the forecast, the restrictions in
paragraphs (b) and (c) of this section
based on forecast conditions do not
apply.

§ 125.223 Airborne weather radar
equipment requirements.
(a) No person may operate an air-
plane governed by this part in pas-
senger-carrying operations unless ap-
proved airborne weather radar equip-
ment is installed in the airplane.
(b) No person may begin a flight
under IFR or night VFR conditions
when current weather reports indicate
that thunderstorms, or other poten-
tially hazardous weather conditions
that can be detected with airborne
weather radar equipment, may reason-
ably be expected along the route to be
flown, unless the airborne weather
radar equipment required by paragraph
(a) of this section is in satisfactory op-
erating condition.
(c) If the airborne weather radar
equipment becomes inoperative en
