Chapter Eight Anti-Ice and Defog Systems

CHAPTER EIGHT

ANTI-ICE AND DEFOG SYSTEMS

800. INTRODUCTION

This chapter discusses the anti-ice and defog systems installed on the aircraft. The aircraft is

capable of flying in all weather; therefore it is essential you understand the capabilities and

limitations of the system. This knowledge will help build a solid foundation for understanding

the potential hazards associated with flying in dynamic weather conditions and the

responsibilities associated with flight in adverse weather conditions. Additionally, it provides

you with an understanding of these systems to aid in understanding operating procedures and

limitations.

The icing protection systems prevent ice on the following areas:

Wing leading edges

Horizontal stabilizer

Air Data Systems (ADS)

Pitot tubes

Static ports

Angle-of-Attack (AOA) vanes and transmitters

Flight deck windows

Windshield imbedded heater elements

Supplemental windshield and side windows defogging is provided by

the ACU and EHS

801. ENABLING OBJECTIVE

Recall the basic description, related components and systems, and operating limitations of the

anti-icing and defog systems.

802. ENABLING STEPS

List all limitations for operation of anti-icing equipment on the ground and in flight.

State procedures and limitations for using windshield heat.

Recall the indications of illuminated annunciators.
