At idle speed on the P-6, what is the required RPMs?

Explanation:
Idle speed is the engine speed with no load on the propulsion system. For the P-6, 1400 RPM is specified as the idle setting because at that speed the engine can maintain adequate oil pressure and lubrication, keep the cooling system and accessories running smoothly, and allow the governor to react to small changes without stalling. Going much lower risks oil pressure drop and stalling; going higher wastes fuel and adds unnecessary wear. So 1400 RPM is the appropriate balance for idle operation.
