PPT contains basic information of aircraft/aeroplane icing and the methods or devices (icing prevention and removal system) to avoid such phenomenon.

2. LITERATURE REVIEW
 Fikret Caliskan , Chingiz Hajiyev
The paper aims at the detection and identification of airframe
icing using statistical properties of aircraft dynamics and
reconfigurable control protecting aircraft from hazardous icing
conditions.
 Guo fan , Chang shinan
This paper describes the principle of electro-impulse de-icing
(EIDI) system of an aircraft which use electromagnetic force to
remove ice.
 Mark G. Potapczuk
The research paper covering the icing environment,
investigations into the physics of ice accretion on aircraft
surfaces,engine performance, icing instrumentation
development etc.

3. INTRODUCTION
 In aviation, aircraft icing are those atmospheric
conditions that can lead to the formation of
water ice on the surfaces of an aircraft.

4. EFFECTS OF ICING

5. ACCIDENTS
 Aircraft icing is one of the major weather
hazards to aviation and has resulted in several
fatal accidents.

6. CAUSES OF ICING
1. Liquid Water
Content
(LWC)
 Amount of available
water
 Varies from cloud to
cloud
 Varies within same cloud

7. 2. Temperature
Most icing tends to occur
at temperatures
between 0°and -20°C
More than 50% of those
occur between -8 and -
12°C
CAUSES OF ICING

8. CAUSES OF ICING
3. Water Droplet Size
Icing patterns change with
droplet size.
In relation to icing hazards
–Droplet size not as important
as
LWC and Temperature
