Avidyne Entegra is an integrated aircraft instrumentation system, produced by Avidyne Corporation, consisting of a primary flight display (PFD), and multi-function display (MFD).
 Cirrus became the first customer of the Entegra system and began offering it on the SR20 and SR22 aircraft in 2003 as the first integrated flight deck for light general aviation (GA).
 The original Entegra system was designed to use third-party components such as a GPS from Garmin and an autopilot system from S-TEC Corporation.
The Cirrus Aircraft Corporation (formally Cirrus Design Corporation) is an aircraft manufacturer that was founded in 1984 by Alan and Dale Klapmeier to produce the VK-30 kit aircraft.
 The company headquarters is located in Duluth, Minnesota, United States.
 As of June 2015, Cirrus had delivered over 6,000 aircraft in 16 years of production, and has been the world's largest producer of piston-powered aircraft since 2013.
The Cirrus Airframe Parachute System (CAPS) is a whole-plane ballistic parachute recovery system designed specifically for Cirrus Aircraft's line of general aviation light aircraft including the SR20, SR22 and SF50.
 The design became the first of its kind to become certified with the FAA, achieving certification in October 1998, and remains the only aircraft ballistic parachute used as standard equipment by an aviation company.

 The engine featured fuel injection.
Ampyx Power is an airborne wind energy company founded in 2008 by Bas Lansdorp and Richard Ruiterkamp.
 It was created after Lansdorp dropped his five-year-long studies of wind energy at Delft University of Technology to found Ampyx Power.
 In 2011, Lansdorp sold a majority of his Ampyx Power shares to fund his new project, Mars One.
 Wubbo Ockels' interest in energy began when he let a kite line slip and it burned his hand.
 He became interested and started to study and research how this could be turned into electricity.
 At Delft University, he formed a team with Bas Lansdorp that worked on developing kites that could retrieve energy from the sky.
 Richard Ruiterkamp became the team leader and he created a fixed wing aircraft that allowed greater controllability and allowing the generation of more energy.
 In 2008 he founded the company with Bas Lansdorp.
 Lansdorp worked on the business aspect, and Ruiterkamp was head of the science division.
 Currently, Ampyx Power has a team of 40 engineers.
 Their current prototype is the AP3 Ampyx Power Airborne Wind Energy System (AWES).
 The system is a tethered aircraft that converts wind into electric energy.
 The aircraft is tethered to an on the ground generator.
 When the aircraft moves and flies, it reels the tether and powers the generator.
 The plane is then reeled in through the tether and then re-released into the air.
The Cirrus SR22 is a single-engine four- or five-seat composite aircraft built from 2001 by Cirrus Aircraft of Duluth, Minnesota.

Krossblade Aerospace Systems is an aviation company founded in 2014 in Phoenix, Arizona, USA.
 The company is known for developing a 5-seat hybrid, vertical take-off and landing, VTOL concept, SkyCruiser, and for its drone/UAV prototype, SkyProwler.
 Both aircraft employ the switchblade transformation mechanism to transform from a multirotor aircraft for vertical take-off and landing, to a pure winged aircraft, for rapid and efficient cruise.
