The PZL M-24 Dromader Super (a.k.a. Super Dromedary) is a single engine agricultural aircraft, developed in the 1980s by the WSK-Mielec (later PZL-Mielec) from the PZL-Mielec M-18 Dromader. It did not progress beyond the prototyping stage.

Development
The plane was developed as a bigger and more capable variant of the successful agricultural plane PZL-Mielec M-18 Dromader. Some components of the M-18 were used it its construction, but it is generally bigger and stronger, with a more powerful engine. The wings were fitted with a new central section of a larger span.
The first prototype of the M-24 flew on July 20, 1987, and was powered with a 736 kW (987 hp) Shvetsov ASh-62IR radial engine. The second prototype, designated M-24B, was powered by the Polish-designed 890 kW (1,200 hp) PZL-Kalisz K-9AA radial engine and first flew in 1988. The third prototype, M-24T, was powered by the Pratt & Whitney PT6A-45AG turboprop engine. Four prototypes were built, but the type did not enter production.
The experience with the M-24 was utilised in creating the M-18B variant of the M-18, powered with the PZL K-9 engine, first flown in 1993.
Design
The aircraft is a metal low-wing cantilever monoplane, conventional in layout. It has a monocoque fuselage, covered with duralumin. The wings are composed of three parts, fitted with flaps and slats. There is a two-seat cabin (pilot and optional passenger or mechanic, in tandem), placed high. The single radial engine has a four blade propeller. Behind the engine is an internal 2,700-litre (590 imp gal; 710 US gal) tank for chemicals or water. A fuel tank holds 1,400 litres (310 imp gal; 370 US gal).
The plane has exchangeable sets of equipment for spraying, cropdusting or fire extinguishing. It has conventional fixed landing gear with a tail wheel.
