Answer

Brief Explanations:

For a fixed-pitch propeller aircraft with a float-type carburetor, carburetor ice restricts fuel-air flow. Since the propeller pitch is fixed, the first noticeable effect is a reduction in engine speed (RPM) as the engine's power output drops. Engine roughness typically occurs later, and temperature drops are not the primary early indicator.

Answer:

loss of RPM.
