Alternatively, a constant-speed propeller is one where the pilot sets the desired engine speed , and the blade pitch is controlled automatically without the pilot's intervention so that the rotational speed remains constant. The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit.
Same as the IO-360-A1A but set up for operation in an inverted position. Differences include a front-mounted propeller governor, two dry oil sumps, dual external oil scavenge pumps, an oil tank, three options of position for fuel injector mounting and provisions for a constant speed propeller.

However, the actual propeller speed remains stable only if operational conditions (e.g., airspeed) do not change, otherwise the pilot has to constantly adjust the pitch to maintain the desired propeller speed. Constant-speed propeller control system simplifies this for the pilot by introducing a propeller governor, where the lever controls the ...
A 6-bladed Hamilton Standard 568F propeller on an ATR 72 short-haul airliner. Lowry [27] quotes a propeller efficiency of about 73.5% at cruise for a Cessna 172.This is derived from his "Bootstrap approach" for analyzing the performance of light general aviation aircraft using fixed pitch or constant speed propellers.
Aircraft fitted with variable-pitch propellers or constant speed propellers are started in fine pitch to reduce air loads and current in the starter motor circuit. [ citation needed ] Many light aircraft are fitted with a 'starter engaged' warning light in the cockpit, a mandatory airworthiness requirement to guard against the risk of the ...
Power 115 hp (86 kW) at 2800 rpm, dry weight 250 lb (113 kg) Similar to O-235-C1 except crankcase and crankshaft supply pressurized oil to a constant speed propeller. Accessory case changed to accommodate a standard propeller governor drive.
The major improvement in Bellanca's introduction of the Super Decathlon was the change of engine to the Lycoming AEIO-360-H1A or –H1B, both of 180 horsepower (130 kW), which was accompanied by a selection of constant speed propellers. The American Champion Super Decathlon uses the AEIO-360-H1B, along with a constant speed propeller.
