Pzl-Mielec M-18 Dromader

Single Piston

The PZL-Mielec M-18 Dromader is a Polish single-engine agricultural aircraft that stands out as one of the largest and most powerful purpose-built crop dusters ever produced. First flown in 1976, the Dromader was designed by WSK PZL-Mielec to meet the demanding requirements of large-scale agricultural aviation, featuring a massive 1,000-horsepower PZL-3S radial engine and a chemical hopper capacity of up to 2,700 liters. Its robust all-metal construction and high-wing configuration allow it to operate from rough, unprepared strips in remote agricultural regions, while its low-speed handling characteristics and excellent visibility make it ideal for precision application work at altitudes often below 10 feet. What makes the M-18 particularly notable is its sheer scale compared to typical ag-aircraft. With a maximum takeoff weight exceeding 12,000 pounds, it dwarfs American competitors like the Air Tractor AT-802 and Thrush 510G, allowing it to cover more acreage per sortie. The Dromader has been exported to over 20 countries and remains in active service decades after production began, with variants adapted for firefighting, parachute dropping, and even geophysical survey work. Its radial engine—a rarity in modern aviation—gives it a distinctive sound and the ability to run on lower-grade fuels in developing markets. The type's operating envelope reflects its specialized mission: a never-exceed speed of 162 knots keeps it well within the structural limits needed for low-altitude maneuvering, while its stall speed of 54 knots in landing configuration allows safe operation in confined areas. The Dromader cruises efficiently at around 100-110 knots, balancing fuel economy with productivity during long spray runs. SkyMeter has tracked 41 flights across 3 airframes and 3 operators, with GLENN AIR INC the largest observed operator.
