A global mosquito-control solution supplier was ready to upgrade its aerial system.
Shrinking the Potential for Mosquito-Borne Disease
A global mosquito-control solution supplier on the front lines of the fight against these pesky insects was ready to replace a popular but decade-old aerial application system with a new version that would take advantage of faster hardware and responsive high-resolution touchscreens. The re-envisioned mosquito-control solution would automatically provide pilots with accurate guidance to and through the ground zones set to be sprayed with chemicals, while accurately avoiding other predetermined zones to limit risk to public health and wildlife.
The client made several requests. They wanted the new system to work equally well on fixed and rotary wing aircraft. They asked for a user interface that was intuitive and easy-to-use both day and night, and capable of delivering a rich visual representation of current guidance, map data, and “spray,” “no-spray” and “already sprayed” zones. They also wanted a simple, reliable means of backing up mission data and upgrading system software. Plus, the system had to be able to create a detailed log of aircraft movement, weather conditions and spray operations for each mission that could be securely retrieved for debriefing and analysis.
ICS tackled both UX design and engineering, assembling a team of C++, Qt, OpenGL and QML developers to tackle critical software implementation tasks, and visual designers to ensure the UI was on point. Quickly ICS’ UX experts created a prototype of the application’s UI that significantly improved on the previous generation of the system.
The new UI included a streamlined menu system featuring comfortable navigation and data entry during mission preparations on the ground, as well as in-flight, when aircraft vibrations make touchscreen input precision more challenging. The UI also incorporated day and night themes (night mode usable with night vision goggles) and a means to transparently switch between various units (meters, kilometers, feet, kilometers per second, knots, etc.) without loss of precision.
The ICS team also developed a fluid and responsive guidance system that accurately displayed vector and raster geographical maps, as well as spray and no-spray zones, sprayed areas and guidance information, taking advantage of data from weather sensors and GPS. The application can turn chemical spraying on and off automatically based on aircraft position relative to the spray zone. It also allows for manual control when pilots deem necessary.
Other key features include functions that allow the pilot to save fuel and shorten flight time; an option to either use existing spray zones or define new ones on the fly; and an integrated obstacle awareness subsystem relying on FAA obstacle data.
The cutting-edge new system has created a buzz in the industry. Mosquitoes, you’ve been forewarned.
