Reliable Pratt & Whitney R-985 power
Effective control of spray pattern
Efficient control surfaces, tip vanes, Weath-Aero fan and the pneumatic boom system work together with the 620B's agile flight characteristics and instant control responses to enable you to do a better job than competitors who only wish they owned a Weatherly. With just a flick of a finger the airplane puts the spray where you want it - and keeps it from going where you don't. An environmentalist may even invite you to lunch!
Weatherly's leadership continues with the innovative Weath-Aero fan. It's blades feather during ferrying and at the end of a spray run. This reduces drag to a small fraction of the drag offered by old-fashioned fixed pitch, brake type fans. The operator adjusts the blade angle during flight to obtain the needed boom pressure. This results in better control of the spray pattern, keeping you another step ahead of the competition. Weatherly's competitors offer the Weath-Aero fan as an option - Weatherly Aviation offers it as standard equipment.
The 620 series airplanes feature Oleo landing gear suspension, pinned at the spar so that landing loads are transmitted to the spar in a manner that avoids twisting stresses. A trailing strut carries forward and aft loads during landing. The landing gear's wide track provides excellent ground handling characteristics not available from a spring type landing gear. There are also no side loads on the tires during normal landings. This means that you can be flying while your competitor is driving to the tire store!
If you always like to see where you're going, where you've been and what you're doing, you should be flying the 620B. The redesigned cockpit makes the pilot's workplace a comfortable and safe environment.
The 620B fuselage features monocoque construction to reduce airframe weight. It allows simple less expensive replacement in the unlikely event that damage occurs. Large openings and removable panels make the 620B easy to inspect and maintain. The hopper construction is sturdy, chemical-resistant and tough. The wing leading edges are attached with piano hinges to the wing is easily inspected for damage or corrosion.
Night lighting option
The Weatherly night lighting system allows you to work while your competition sleeps. This option features two 600 watt lights, turning lights, wing tip strobes along with a larger alternator. It effectively lights the flight path for safe night spraying and fertilizing operations.
