Homework

The exposure to input

Students need to listen to this clip about what bleed air is and its function to discuss.

How does the bleed air system function?

Using a mind map to open a dialogue between your students activates them and provide a more interactive stimulation for understanding. 

Bloom taxonomy level 2: Understanding

Bloom's taxonomy verb: 

Why are the main components so important to the bleed air system?

1. Because they are necessary parts in the creation of pneumatic power
2. Because it is necessary to provide pneumatic power to the pneumatic system in the specific aircraft.

For a more result-oriented overview of student understanding, add global MC to keep students focus on the lesson topic and to stimulate critical thinking.

*It helps to put timers on these questions to energize students

What is bleed air?

1. It is just extracted air that is being used in the pneumatic system
2. It is hot, highly compressed air that is taken from the airplane's engine.

Exercise 1 - Vocabulary 

After watching the video, complete the following: 

• Go to exercise 1 a and b
• List the pneumatic components mentioned in the video.
• Describe in your own words what the pneumatic system is and does.
• Match the functions of the components and list the systems they supply power to.

APU

Processing content: 

I used an ICT feature called "drag and drop" for students to place in the correct order.

The focus of this activity is to remind them which systems the pneumatic system powers.

Exercise 2: Answers

1. What is bleed air?

Compressed, highly pressurized air that is very hot. It is used to power certain systems that require energy from pressurized air.

 

2. Is the temperature of the bleed air stable?

No, it varies a lot depending on where it’s extracted from. It varies from 250 degrees Celsius.

 

3. Name three systems that bleed air provides with power.

Engine one and two start systems, air-conditioning and cabin pressurization, engine one and two anti-ice systems, wing anti-ice systems, water tank pressurization system, hydraulic system A and B reservoir pressurization system, air temperature probe aspiration system and nitrogen gas generation.

Exercise 2: Answers

 

4. What is the function of the pneumatic manifold system?

It collects all the air from the three systems that provide pneumatic power.

 

5. What is the function of the bleed air isolation valve?

It divides the pneumatic manifold in a left and a right side, this provides system redundancy.

Exercise 2: Answers

6. What is the function of the duct pressure transmitters?

It provides indications to the duct pressure pointers in the forward overhead panel.

 

7. From which part of the engine is bleed air extracted?

The compressor section, the 5th and 9th stage.

 

8. What is the function of the fifth stage check valve?

It prevents bleed air from the 9th stage to get into the 5th stage bleed airport.

Exercise 2: Answers

9. What is the function of the PRSOV?

It regulates pressure to 42 psi; it gives bleed air temperature limitation to 235 degrees Celsius and bleed air shutoff.

 

Bonus question:
What does PRSOV mean?

1. Pneumatic Software Regulating Valve
2. Pressure Regulating Shut-Off Valve

Bonus question:
What is the ideal bleed air temperature?

1. Between 199 and 229 degrees Celsius
2. Between 99 and 229 degrees Celsius
3. Between 199 and 239 degrees Celsius
4. Between 200 and 300 degrees Celsius

Keep working!

In the future, you will need to read a lot of manuals at your job. It is very important to read manuals carefully. If you miss something, that might lead to a catastrophic mistake.

Some paragraphs were missing from the manuals

You will find the missing paragraph in the table

Place the missing paragraphs at the correct gap in the text

everything you learned about the pneumatic system in an info graph. 

Use the program Canva to create your own infography.

Click on the following slide to get create your own Canva account. 

Output: 

Every output should involve CLT (communicative language teaching) because it encourages the students to produce what they've learned product.  This will ensure retention and better understanding of how it all works. 

You can even add an extra detail to that activity by suggesting the students to use the vocabulary that was used in the lesson or the grammar topic that was discussed.
