ATPL (Philippines) - Flight Performance & Planning 3 actual test 2023/2024

ATPL (Philippines) - Flight Performance & Planning 3 1. Minimum specific fuel consumption of the turboprop engine is normally available in which altitude range? a. 25,000 feet to the tropopause. b. The tropopause to 45,000 feet. c. 10,000 feet to 25,000 feet. - correct answers a. 25,000 feet to the tropopause. 2. What effect would a change in ambient temperature or air density have on gas-turbine- engine performance? a. As temperature increases, thrust increases. b. As air density decreases, thrust increases. c. As temperature increases, thrust decreases. - correct answers c. As temperature increases, thrust decreases. 3. As outside air pressure decreases, thrust output will: a. increase due to greater efficiency of jet aircraft in thin air. b. decrease due to higher density altitude. c. remain the same since compression of inlet air will compensate for any decrease in air pressure. - correct answers b. decrease due to higher density altitude. 4. What effect will an increase in altitude have upon the available equivalent shaft horsepower (ESHP) of a turboprop engine?: a. Power will remain the same but propeller efficiency will decrease.
