Slipstream
The column of air pushed rearward by a rotating propeller; it always moves faster than the aeroplane itself.

SLIPSTREAM - The flow of air driven backward by a propeller or downward by a rotor. Compare DOWNWASH.
Slipstream: The stream of air behind a propeller which usually has about 20 per cent greater speed than that of the aeroplane, at every speed.
Slipway: The inclined place used for hauling boat and float seaplanes into and out of the water.
The helical slipstream will also meet the horizontal stabiliser at an angle but the resultant effect is difficult to determine or distinguish.

[edit] Non-aerodynamic criticality
On certain aircraft, hydraulic, pneumatic or electrical systems may be powered by one engine. This engine would therefore be critical in this respect.
Added to this is the fact that slipstream from the propeller over the inner part of the wing and tail section improves effectiveness and delays the separation of the airflow near the wing root.
Suddenly there was no sound other than the sound of the slipstream. In my anxiety, I had failed to allow for time for adequate descent.
The next thing to notice is that on practically all aircraft, the vertical fin and rudder stick up, not down, projecting well above the centerline of the slipstream.
COCKPIT VOICE RECORDER (CVR) — A crash-resistant device featuring a very sensitive microphone to digitally record sounds heard in the cockpit of an airplane: pilot-to-pilot conversation and comments, warning horns and signals, slipstream, ...
The wing design minimizes the frontal area in the propeller slipstream for increased performance, and also provides direct prop blast to the tail sections for superior controllability in slow flight.
VENTURI TUBE - A small, hourglass-shaped metal tube, usually set laterally on a fuselage in the slipstream to create suction for gyroscopic panel instruments. Now outdated by more sophisticated means.
The next innovation was a fully deflectable horizontal stabilizer that directed propeller slipstream into the rotor. Cierva {license?

is then created by an increase or decrease in thrust, plus another contribution due to an increase or decrease in the speed over a small part of the wing and most part of the horizontal tail. (On a "tee" tail configuration, the propeller slipstream ...
The slipstream from the Lycomings makes that portion of the wing much more effective and dramatically drops the Vmc with one of the main engines out.
I use the words appropriate amount because it's possible that you may not even need to apply left rudder when entering a climbing left-hand turn thanks to our good friends P-factor, torque, the propeller slipstream and gyroscopic precession.
