1. Hold the elevator so that its trailing edge aligns with the horizontal tail tips (take the average if
left and right align differently) throughout this procedure. Use adhesive tape between elevator
trailing edge and elevator tips to temporarily align the elevator to neutral deflection in alignment
with the horizontal tail tips.
2. Secure digital inclinometer to the top of the trim tap surface with double-side tape. Ensure that
its long axis is perpendicular to tab hinge line and that it does not interfere with tab operation.
3. Operate the trim tab until its trailing edge aligns with that of the elevator. Zero the inclinometer.
