01The problem

Hours in Visio and AutoCAD for every install.

Avionics shops and homebuilders have long drawn their interconnects by hand in general-purpose tools, spending hours on monotonous detail work for every installation. SkyWire Studio cuts that out with prefabricated symbology and populated LRU templates that are easy to modify, so a drawing that used to take hours takes minutes.

SkyWire Studio changes that.

  • Using SkyWire Studio has been a great addition to our avionics installation and modification workflow. We appreciate its intuitive user interface, the flexibility to create custom LRUs and symbols, and the convenience of its cloud-based platform, which enables seamless collaboration between users. Technical support is outstanding. The founder truly stands behind his product.
    Paul Haglund — Avionics Manager, Kenmore Air Harbor
  • SkyWire Studio has been a good way to get drawings done quickly. If you want to keep a crew moving, quick drawings are a must. SkyWire cuts out all the monotonous detail work and gets you going with prefabricated symbology, and LRU population that is easy to modify.
    Steve P. — Propelling Aviation
  • SkyWire Studio has made it easy to organize my avionics wiring into professional diagrams. What used to take hours in Visio, now only takes seconds to minutes.
    Alex J. — RV-7 Homebuilder
  • I spent a good chunk of my engineering career using AutoCAD to make wire schematics and I've enjoyed what you have with SkyWire for avionics focus in mind!
