About The STC Group

The STC Group LLC designs and obtains regulatory approvals for the installation in certificated aircraft of autopilots manufactured by Trio Avionics. The same outstanding warranty support that Trio Avionics provides to the Experimental community is provided for certificated aircraft.​

Fusing Tech With Tradition The STC Group team was assembled to certify the Trio Pro Pilot Experimental autopilot after becoming frustrated with efforts to install a traditional aftermarket autopilot in the CEO’s 1975 Cessna 182P. The STC Group LLC team found that typical analog autopilots were expensive to buy and install and not very sophisticated.
