"Air density is perhaps the single most important factor affecting airplane performance. Do you agree with this statement? Why or why not?"
This is a great ICAO test question as it allows a candidate to talk about principles of aerodynamics in his own words.
ICAO TEST MODEL ANSWER
We are not going to give you a model answer, but we will help you construct a good answer.
When planning your answer consider these factors:
- lift generated by the wings
- efficiency f the propeller
- power output of the engine
- dry air
Also consider the effects of density altitude:
- attain the same lift
- avoid stalling
- reduced power production
- lower service ceiling
Essential Aviation English vocabulary
lift, airfoil, propeller, humid, reduced, decreased, true, obstacles, altitude
A candidate will also be able to use different forms of a word, eg efficient, efficiency, efficiently so make sure you know your parts of speech.
