What ways can you detect icing in flight?

Weather radar is designed to detect large droplets since they are not only an indication of potential in-flight icing but also updrafts and wind shear. Runback ice forms when supercooled liquid water moves aft on the upper surface of the wing or tailplane beyond the protected area and then freezes as clear ice.

Which parts of the aircraft are anti iced?

Large, turbine powered aircraft typically are equipped with anti-ice systems that use hot com- pressed air (called bleed air) that is tapped off the compressor section of the engines to prevent ice from forming on critical engine components such as the air inlet lip and the turbine engine inlet guide vanes.

What is the effect of flying with total Anti-ice on?

The ice changes the airfoil cross section and destroys lift, increases drag and raises the stalling speed. At the same time, thrust is degraded because of ice on the propeller blades and the pilot finds himself having to use full power and a high angle of attack just to maintain altitude.

What is ice prevention in aviation?

Ice Prevention Several means to prevent or control ice formation are used in aircraft today: Heating surfaces with hot air. Heating by electrical elements. Breaking up ice formations, usually by inflatable boots.

How are ice detectors used on an airplane?

Ice can be detected visually, but most modern aircraft have one or more ice detector sensors that warn the flight crew of icing conditions. An annuciator light comes on to alert the flight crew. In some aircraft models, multiple ice detectors are used, and the ice detection system automatically turns on the WAI systems when icing is detected.

How are anti-ice systems used in aircraft?

Large, turbine powered aircraft typically are equipped with anti-ice systems that use hot com- pressed air (called bleed air) that is tapped off the compressor section of the engines to prevent ice from forming on critical engine components such as the air inlet lip and the turbine engine inlet guide vanes.

What are the ice protection requirements for aircraft?

PROTECTION REQUIREMENTS 2 6.1 Ice Protection Requirements: Unintended Exposure to Icing Conditions 3 6.2 Ice Protection Requirements: Intentional Operations in Known and Forecast Icing Conditions 4 6.3 Ice Protection Requirements: Operating Safely in Icing Conditions 5 7.

When to use wing anti ice ( Wai ) in flight?

See Instrument Probes page for explanation. Wing anti-ice (WAI) is very effective and is normally used as a de-icing system in-flight, in applications of 1 minute. On the ground it should be used continuously in icing conditions.
