What does an in-line engine look like?

• Like a normal engine

• The cylinders are lined up in a row from the front of the engine to the back, with the tops pointed up

• Cylinders vertically placed on each other

• Cylinders stacked horizontally

How are the cylinders arranged in a horizontally opposed engine?

• vertically placed on top of each other

• that is not an engine type

• A horizontally opposed engine has two banks of cylinders lying flat, directly opposite each other

• horizontally stacked on each other

Why are horizontally opposed engines the favoured design for small aircraft engines?

• the horizontally opposed engine’s flat shape generates less form drag

• because thats how physics work

• large aircrafts need bigger engines

• it's very light so it is easy for the smaller aircrafts

What are the two types of engine arrangements we learned today?

• horizontally opposed and in-line

• horizontally opposed and off-line

• vertically opposed and in-line

• vertically opposed and off-line

What is the most common engine arrangement?

• not opposed

• vertically opposed

• diagonally opposed

• horizontally opposed

What is form drag?

• brings the aircraft up

• a force that GOES with the aircraft's movement in the air

• a force that opposes the aircraft's movement in the air

• moves the aircraft forward

TRUE OR FALSE: The in-line engine was the first mass produced engine type.

• True

• False

Why is it important to learn about this?

• develop an understanding of subsequent and related principles of aviation

• orient and generate interest

• So we don't crash planes

• it is not important

What was today's lesson about?

• Engine arrangements

• leadership

• survival

• drill
