STC Now Updated To Include Additional Cessna And Piper Models
The STC for the TruTrak Vizion autopilot has been updated to include the remainder of the Cessna 172 series , the Cessna 175 series, the Piper PA28 series, and the PA32 series aircraft. These aircraft are added to the existing AML STC which currently includes the Cessna 177 series and part of the Cessna 172 series aircraft. The next models to be added the STC will be the Cessna 180, 182, and 185 series aircraft.
In July of 2017, the initial STC was issued for the Vizion Autopilot system. The completion of that STC brought a truly affordable two-axis autopilot to the Cessna 172 aircraft. The Cessna 177 was added in the early fall of 2017. The plan for the remainder of 2018 is to concentrate on adding many aircraft to the AML.
According to TruTrak, the Vizion autopilot will neither let the pilot accidentally stall or overspeed the aircraft with the use of minimum and maximum airspeed settings. Also included is the Emergency Level feature, which allows the pilot to press one button and the autopilot will engage and bring the aircraft to wings level and zero vertical speed. This mode is unique in that it initially commands wings level, but then switches to track select mode to allow the pilot to more easily select a new desired direction.
Another safety feature of the TruTrak autopilot is AEP. This mode is a bank angle protection mode that the pilot can easily arm / disarm. AEP is used when the autopilot is powered up, but not engaged, in other words when the aircraft is being hand-flown. When armed, AEP monitors the aircraft bank angle and will engage the roll servo with a modulated signal that allows the servo to put a lighter than normal force into the control system. This is not like the autopilot actually engaging, as the pilot may still very easily override the servo. The system simply aids the pilot in lowering the bank angle of the aircraft. This feature was specifically designed with LOC (loss of control) accidents in mind.
