iLevil AP autopilot

Heavy servos are how a certified autopilot moves a control surface, and their weight, their linkages and their installation are why most light aircraft fly without one. The iLevil AP moves a trim tab instead, and lets aerodynamic force do the work: a small servo on a small tab, riveted or bonded to the surface, gives a light-sport or Experimental aircraft a usable autopilot at a fraction of the weight and panel space.

What it flies

• Heading mode — holds a heading from the internal compass and GPS
• Altitude mode — climbs to, descends to and holds an altitude
• Vertical speed — a rate you set
• Flight-plan steering — follows the route on the tablet
• HOLD — wings level, altitude kept, when you need both hands
• Envelope protection — will not let the autopilot fly the aircraft out of its limits
• Auto trim — keeps the aircraft trimmed as the load changes

An iLevil AW inside

The sensor box is a full iLevil: AHRS, pitot-static airspeed and pressure altitude, WAAS GPS, dual-band ADS-B In traffic and weather, data recording. It runs on 12 to 28 V with a 3.5 hour backup battery, and connects to an engine analyser too.

Control from where your hand is

From the tablet, or from the Levil Aviation Joy — the control grip with the NAV button that engages the autopilot and follows the flight plan — or from the wired iLevil AP Controller for a hardwired installation.

What is in the box

One Levil Aviation box with the iLevil AP sensor unit, and one Aircraft Automation box with the trim-tab kit — the servos and the tabs, sized to your aircraft's cruise speed.

• Sensor box 3.2 × 5 × 1.1 inches, 311 g
• Each trim kit including its servo 150 g; tab 12 inches long, 2 inch moving section

Trim-tab kits are sized by cruise speed: Small 140–180 kt, Medium 120–140 kt, Large 80–120 kt, Jumbo 50–80 kt.
