On average, an airplane is struck by lightning more than once per year.

Purpose-Built for High Stakes Applications
Manufacturers such as Boeing and Airbus take every precaution to ensure that electromagnetic interference (EMI) doesn’t interfere with operations of the aircraft and other equipment they supply to commercial and military customers. That includes relying on BAND-IT Tie-Dex bands to terminate connections and shield cables from EMI, in turn securing personal safety and continuous operations.
Commercial and military aircraft carry more electronic equipment with every new design
Fly-by-wire systems are replacing traditional hydro-mechanical controls. TV screens keep passengers entertained and power ports allow you to charge your phone while simultaneously using the on-board WiFi system.
The EMI generated by these and other electronic devices can disrupt pilot/control tower communications, and have been suspected of causing autopilot disconnects and erratic flight deck indications. Today’s digital control systems need to be designed in anticipation of EMI sources from the outside as well. Solar flares, radar and lightning – don’t be alarmed, but an airplane is struck by lightning once each year, on average – threaten system performance and jeopardize safety.
