cooling system

Question 1

what are the temperature indicators in the system

Answer 1

cylinder head temperature

exhaust gas temperature

oil temperature

Question 2

what is the most effective way of cooling

Answer 2

reduce power, ensure mixture rich and increase airspeed

Question 3

how does air cooling work

Answer 3

• engine cowl is designed to form an envelope around engine to force air around cylinder
• engine bay has internal baffles (directs air evenly)
• designed for cruise
• ensures intakes for cooling are clear of obstructions

Question 4

airspeeds greater or lower than cruise =

Answer 4

incorrect engine cooling

Question 5

continuous power settings above or below recommended cruise settings =

Answer 5

incorrect engine cooling

Question 6

what are cowl flaps

Answer 6

assist in engine (cylinder heat temperature) control
- pilot operated

Question 7

what are cylinder fins

Answer 7

fins to increase surface area = air dissipation

Question 8

use a … mixture to aid engine cooling at high power

Answer 8

rich (above 75%)

Question 9

lean mixture = … temp

Answer 9

higher
