Is Trio, Aspen, or Uavionix the Lowest Cost Commercial Training Aircraft in a Cessna 150 or 152?



A technically advanced airplane has an electronic primary flight display, a multifunction display, and a two-axis autopilot. Now, training in a TAA may be logged toward a commercial pilot certificate in a single-engine airplane.

Technically advanced airplane (TAA) has been in the aviation lexicon for several years. Even if you’ve never flown in one, you probably know that it involves electronic flight instrument systems (“glass”) as opposed to traditional analog (“steam” or “six-pack”) gauges.

The FAA originally described a TAA as an aircraft equipped with at least a “moving-map display, an IFR-approved GPS navigator, and an autopilot.” However, in the summer of 2018, the FAA specifically defined the term technically advanced airplane in the federal aviation regulations (61.129(j)). Combined with a change to the requirements for commercial pilot training, this change gives career-bound pilots access to more—potentially more modern and less expensive—options for training aircraft.
