Refer to Normal Procedures, Cold Weather Operations, if the airplane has been exposed to ambient temperatures below –10˚C(+14̊ F) for a prolonged period.
If the brake system has been pressurized, the brakes can be bled down to precharge level by pressing the silver button circledabove to release fluid pressure.
EXTERIOR INSPECTION
During inspection, make a general check for security, condition and cleanliness of the airplane andcomponents. Check particularly for damage; fuel, oil, and hydraulic fluid leakage; security of accesspanels; and removal of keys from locks.
