aircraft systemsFAA-published sample question (AGI, Aug 2021)
Air cooled engines dissipate heat
A
through cooling fins on the cylinder and head.✓ Correct Answer
B
by air flowing through the radiator fins.
C
through the cylinder head temperature probe.
Explanation
Air-cooled engines dissipate heat through cooling fins on the cylinders and cylinder heads, with baffles directing airflow over them (PHAK Chapter 7). Radiators belong to liquid-cooled engines, and a temperature probe only measures heat.
