Because the Weatherly 620GTG is an efficient airplane, it can carry the same load as its competitors with less power. This means less fuel and more profit. Maintenance is less than competitive airplanes.

Effective control of spray pattern

Efficient control surfaces, tip vanes, Weath-Aero fan and the pneumatic boom system work together with the 620BTG'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!

Outstanding cockpit visibility and comfort

If you always like to see where you're going, where you've been and what you're doing, you should be flying the 620BTG. The cockpit makes the pilot's workplace a comfortable and safe environment.

Heavy-duty landing gear

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!

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.

Weath-Aero fan cuts costs

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.

Rugged construction

The 620BTG 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 620BTG 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.

Tip vanes for increased efficiency

Only Weatherly airplanes offer the wing tip vane feature. They diffuse the normal formation of the wing tip vortex< creating a strong downwash outboard of the tip, introducing smaller vortices in the tip area. This results in both a delay in the formation of the trailing vortex and a decrease in its intensity. What the operator sees is and increase in hte speed of the airplane at a given power setting and a more even distribution of the spray pattern without drift. Competitive aircraft will have tip vanes one day, but until then, you can only get them on a Weatherly.

The wing's the thing

  • The 620BTG wing has a high lift to drag ratio, resulting in excellent all-around performance for ag operations.
  • With a 15 percent thickness wing you can fly slowly over a small field - performing jobs your competitors only wish they could.

The 620BTG allows you to spray where you want to

  • The airplane is nimble and quick.
  • Wing tip vanes control the tip vortex, reducing drift.
  • Aerodynamically balanced controls allow precision flying.
  • The 620BTG reduces pilot fatique
  • Control forces are light
  • Noise levels are low
  • Spacious cockpit

The 620BTG makes you money

  • Less fuel is used to pull the airplane through the air
  • It hauls more load, faster and at less cost
  • Tire war is far less than with spring gear airplanes
  • 116 gallons of usable fuel
