Pro Line 21™ Integrated Avionics System


Rockwell Collins Pro Line 21™ is a family of flexible avionics system solutions designed to address a wide range of aircraft and missions. From light turboprops to long-range business jets, from commercial helicopters to special missions aircraft, Pro Line 21 gives you flexibility in flight deck configuration and flight display formatting.

Rockwell Collins Pro Line 21 systems are flying on aircraft delivered from the factory and are also available as aftermarket upgrades. Continuous improvements to existing Pro Line 21 systems bring new capabilities to you as operating requirements evolve. Retrofit packages have also been developed for many aircraft to give you a modern “glass cockpit” and add value to your aircraft investment.

Whether you are looking to enhance your existing Pro Line 21 avionics system or wanting to upgrade to more reliable and capable avionics, Pro Line 21 is the right choice.
