1 UNIT 8 METEOROLOGY Flying VFR means that we need a minimum amount of visibility to fly safely. Day or night makes no difference to the visibility or transparency of air. But, what do you understand by visibility ?  Talk to your partner and try to provide a definition. Now have a look at this one: It is the ability to see through air. Clean clear air allows for a better visibility than air polluted with dust and particles.  What weather phenomena do you know that can affect visibility? Mention them.  Now, read the following extract and later, explain these to your partner using your own words. Precipitation Rain or snow reduce visibility. A drizzle will not hinder VFR operations. Fog/mist Fog is visibility less than 1000 metres and Mist is visibility between 1000 and 5000 metres. Haze When visibility is reduced to 5000 metres or less by the presence of dust particles it is called haze. When dust or sand particles are blown off and visibility reduces to less than 1000 metres it is referred to as dust or sand storm. Smoke Industrial activities and fires in residential areas a dd soot and carbon to the environment. This adds enough condensation nuclei to the air so that condensation will take place and thus smog is formed. sea spray It adds salt particles to the air thus increasing the amount of condensation nuclei.

How many different weather conditions can you name now?

Clouds play an important role in determining weather conditions . Watch the following video andtake down notes on:

Types of clouds Description of these

You may need to watch the video twice to analyze vocabulary

Drizzle: stratus clouds + nimbostratus cloud.

Rain: the most common type of precipitation whentemperatures are above zero.

Snow: snow pellets are little grains of ice with a milky whiteappearance and spherical shaped. (sleet: rain and snow)

In what order is ATIS information usually given? What information is mandatory?What information may be optional? Why is this information so critical for both

pilots and controllers?

Oral Practice:

Role playing: take turns to give an actual updated weather report. Use the blank table belowto take notes.

I'm going to have terrible indigestion.

NOTE: It is unusual to say 'I'm going to go to...'Instead, we use 'going to' + a place or event :

We are going to the beach tomorrow. She is going to the ballet tonight. Are you going to the party tomorrow night?

Simple future form

The 'simple' future is composed of two parts: will + the infinitive without 'to'

Subject will infinitive without to

He will leave...

Affirmative Negative Interrogative

I'll see I won't see Will I see?

*I will see I won't see Will I see?

You 'll see You won't see Will you see?

He, she, it will see He won't see Will she see?

We 'll see We won't see Will we see?*We will see We won't see Will we see?

You will see You won't see Will you see?

They 'll see They won't see Will they see?

*NOTE: shall is slightly dated but can be used instead of will with I or we.

The simple future is used:

to predict a future event:It will rain tomorrow.

(with I/ we ) to express a spontaneous decision:I'll pay for the tickets by credit card.

to express willingness:I'll do the washing-up. He'll carry your bag for you.

(with I in the interrogative form) to make an offer:Shall I open the window?

Final Task:

Surf the internet and find a meteorological web page, and from there, find the weather forecast

for the day and for the week.

Task 1:

Work in pairs. Imagine one of you is a pilot who is planning some visual flights for the incomingweek. Talk to him and give the weather forecast. Use the correct future forms.

Now exchange roles and have a different conversation.

Task 2:

Find a METAR and bring it to the class. Practise reporting the METAR as an ATIS, adding anynecessary information.After practicing it in class, paying attention to pronunciation and vocabulary, record the ATIS athome. Your teacher will then tell you how to correct it.
