9. CONDITION levers As required.
10. Red anticollision light Reset.
To reset, turn off approximately 5 seconds,
then to the NIGHT (red) position. When
voltage drops below approximately 20
volts, the anticollision light may become
inoperative. Normally, NIGHT (red) strobe
is used for ground operations and DAY
(white) is used for flight operations.

AIR/TEMP switches Set as desired.
5. BLEED AIR VALVES As required.
Do not leave brake deice on longer than
required to check function of annunciators

Brake deice control valves may become
periodically. One cycle of the valves is
required daily, regardless of the weather
6. BRAKE DEICE switch As required.
7. Avionics Check and set as required.
8. TCAS TEST and set.
9. FLAPS Check.
10. Altimeters Set and Check.
Never taxi with a flat tire or a flat shock
strut. During taxi operations, particular
attention should be given to propeller tip
clearance. Extreme caution is required
when operating on unimproved or irregular
surfaces or when high winds exist. If
operations produce a propeller RPM over
1600, retard propeller levers to the detent
to limit RPM to 1600 to help reduce the
possibility of ingestion of ground debris.
