Performance and Limitations

Question 1

An aircraft is flying at a constant power setting and constant indicated altitude. What happens to the true airspeed and true altitude if the outside air temperature decreases?

Answer 1

The true airspeed and the true altitude both decrease.

Question 2

If an aircraft is flying at L/D max, what can be said of flying at lower or higher angles of attack?

Answer 2

Total drag is increased.

Question 3

What does the lower limit of the green arc on an airspeed indicator represent?

Answer 3

The poweroff stall speed in a specified configuration.

Question 4

If the atmospheric pressure and temperature remain the same, how would an increase in humidity affect takeoff performance?

Answer 4

Takeoff distance would be longer because the air is less dense.
