If the ignition switch is moved from BOTH to either LEFT or RIGHT during an engine ground check, normal operation is usually indicated by a slight

  1. increase in manifold pressure

  2. bump in propeller rpm

  3. drop in torque meter pressure indication

  4. rise in oil temperature

The correct answer is: bump in propeller rpm

An increase in manifold pressure (A) could indicate air restriction or an engine problem. A drop in torque meter pressure (C) could indicate an issue with the fuel system or an engine issue. A rise in oil temperature (D) could point to oil issues or cooling issues within the engine. Option B, a bump in propeller rpm, is the most likely indication of normal operation during an engine ground check. When the ignition switch is moved from BOTH (meaning both magnetos are on) to either LEFT or RIGHT (meaning only one magneto is on), there is a slight change in timing which can lead to a small increase in propeller rpm. This shows that the engine is running smoothly and both magnetos are functioning properly.
