Look at the table and check if you are right

NB! Take off can be cancelled if temperature is more than +50°C or -50°C.

11. Read the text and answer the following questions. You can use your own experience.

1. What might the reason for icing be?

2. At what stages of flight can icing be dangerous for flight?

3. What are possible consequences of icing?

4. What measures can be taken to prevent ice formation?

5. Can you describe any aviation event where icing was involved?

ICING Temperature can influence safe flying greatly. Changeable temperature (from 0° to -10°) might cause icing of an aircraft and the RW. Icing and icy conditions often lead to airline accidents. Icing of wings is a common problem for an aircraft. It might be very dangerous as even a small amount of ice or frost can greatly reduce lifting power and result in some problems

during take off. If ice builds up during flight the consequences can be catastrophic, that is why aircraft are de-iced before take off. Modern planes are designed to prevent ice buildup on wings, engines and tail. What is more, pilots can have special ice detectors in order to avoid icy areas.
