The An-2 is a mass-produced single-engine [[biplane]] that was deliberately furnished with a minimum of complex systems. The wing leading edge slats that give the aircraft its slow flight ability are fully automatic, being held shut by the airflow over the wings. When airspeed drops below {{cvt|64|km/h}}, elastic rubber springs extend the slats.<ref name = "An-2"/> Under typical conditions, take-off can be made within {{cvt|170|m}} while the landing run requires {{cvt|215|m}}. These figures vary dependent on weight, air temperature, runway surface, and wind direction.<ref name = "An-2"/>

The An-2 is equipped with features which make it suitable [[Bush plane|for operation in remote areas]] with unimproved airstrips. It is fitted with a [[Air brake (road vehicle)|pneumatic brake]] system similar to those used on heavy trucks to stop on short runways, along with an air line attached to the [[compressor]], so the pressure in the [[tire]]s and [[shock absorber]]s can be adjusted.<ref name = "An-2"/> The batteries, while sizable, are easy to remove, and it does not need a [[ground power unit]] for starting the engine. Likewise, there is no need for an external fuel pump to refuel the aircraft as it is provided with its own.<ref name = "An-2"/>

The operating handbook does not explicitly specify a [[Stall (flight)|stall]] speed, stating instead: "If the engine quits in instrument conditions or at night, the pilot should pull the control column full aft and keep the wings level. The leading-edge slats will snap out at about {{cvt|64|km/h}} and when the airplane slows to a forward speed of about {{cvt|40|km/h}}, the airplane will sink at about a parachute descent rate until the aircraft hits the ground."<ref name = "An-2"/>

The low stall speed makes it possible for the aircraft to fly backwards relative to the ground under high wind conditions while under control.<ref name = "An-2"/>

Many western countries prohibit the use of the An-2 commercially because the aircraft has not been certified by the relevant national aviation authorities. These restrictions vary by country, but all prevent the An-2 being used for any commercial purpose, with the exception of the United States, where PZL-built An-2s are exempt from this restriction due to a [[Bilateral Air Transport Agreement|bilateral agreement]] with Poland.<ref name = "An-2"/> Other An-2s are operated non-commercially under an experimental certification.<ref name=harp/>
