737 Operations Manual
Anti–Ice Operation
Requirements for use of anti-ice and operational procedures for engine and wing anti-ice are contained in Supplementary Procedures, Adverse Weather, section SP.16.
Rain Repellent Use
Do not actuate rain repellent unless windshield wipers are operating and medium or heavy rain conditions exist.
CAUTION: Do not use rain repellent in an attempt to clean a dry, dirty windshield. If rain repellent is inadvertently applied, do not use the windshield wipers until required for rain removal.
Inflight operation:
Windshield Wiper selector ....................................... Desired position
Rain Repellent
switches .......................... Push and hold momentarily (one at a time)
Rain repellent may be used any time rain intensity requires the use of
windshield wipers.
One application of repellent should be sufficient for an entire takeoff or landing. Additional applications may be required for takeoff or landing in very heavy rain.
Window Heat System Tests Overheat Test
The overheat test simulates an overheat condition to check the overheat warning function of the window heat system.
WINDOW HEAT switches.................................................................ON
WINDOW HEAT TEST switch.................................................... OVHT
OVERHEAT lights – On
Supplementary Procedures -Anti–Ice, Rain 737 Operations Manual
ON lights – Extinguish Lights extinguish after approximately 1 minute. MASTER CAUTION – On ANTI–ICE system annunciator – On WINDOW HEAT switches ............................................................. Reset Position the WINDOW HEAT switches OFF, then ON.
Power Test
The power test verifies operation of the window heat system. The test may be accomplished when any of the window heat ON lights are extinguished and the associated WINDOW HEAT switch is ON.
WINDOW HEAT switches ................................................................ ON
Note: Do not power test when all ON lights are illuminated
WINDOW HEAT TEST switch ...................................................... PWR The controller is forced to full power, bypassing normal temperature control. Overheat protection is still available. WINDOW HEAT ON lights ..................................................Illuminated If any ON light remains extinguished, the window heat system is inoperative. Observe the maximum airspeed limit of 250 kts below 10,000 feet.
