Feathered propeller on the outboard TP400 turboprop of an Airbus A400M. On most variable-pitch propellers, the blades can be rotated parallel to the airflow to stop rotation of the propeller and reduce drag when the engine fails or is deliberately shut down. This is called feathering, a term borrowed from rowing. On single-engined aircraft ...
The Airbus A400M Atlas [nb 1] is a European four-engine turboprop military transport aircraft.It was designed by Airbus Military, now Airbus Defence and Space, as a tactical airlifter with strategic capabilities to replace older transport aircraft such as the Transall C-160 and the Lockheed C-130 Hercules.

The TP400 large propeller would still have enough ground clearance with the engine installed on the A340 low-mounted wing. [13] A400M showing its counter-rotating propellers on each wing. A small difference in the propeller gearboxes is required to make them go in opposite directions, namely the addition of an idler gear in two of them.

The auto feather system also allows pilots to reduce the drag of the propellers during an engine failure, therefore, allowing the plane to glide for a longer period of time. An automatic feathering system was first introduced on the Martin 4-0-4 aircraft, a piston engine airplane.
The device which controls the propeller pitch and thus speed is called a propeller governor or constant speed unit. Reversible propellers are those where the pitch can be set to negative values. This creates reverse thrust for braking or going backwards without the need to change the direction of shaft revolution.
Swept propeller Scimitar propeller on a 1926 Alexander Eaglerock Eight-blade scimitar propellers on the Airbus A400M Atlas. A scimitar propeller is a type of propeller that has curved blades with increasing sweep along the leading edge. Their name is derived from their visual similarity to the curved blades of scimitars.
A propeller blade in feathered position. In aeronautics, blade pitch refers to the angle of the blades of an aircraft propeller or helicopter rotor. Blade pitch is measured relative to the aircraft body. It is usually described as "fine" or "low" for a more vertical blade angle, and "coarse" or "high" for a more horizontal blade angle.
