Explain how air density affects engine power output.

Explanation should include 

  • how an increase in air density can increase the power output of an aircraft engine 
  • how a decrease in air density can decrease the power output of an aircraft engine. 

Process/Skill Questions:

  • How does air density affect engine performance?
  • Does an aircraft have increased performance when the air is more dense or less dense?
  • What is the effect to engine performance when operating at a high elevation and high temperature?
