Autopilot Installation and Configuration the servo can exert, arm travel, control surface resolution, and the amount of force required to shear the brass shear screw. The two inner-most holes of the servo arm should only be used if the installer fully understands the resulting implications. The diagrams above illustrate the linear travel and available force for each mount point on the standard and long-arm servos. CAUTION: Each Dynon Avionics servo includes a precision-machined brass “shear screw” that pins the servo arm to the servo arm attachment, providing an ultimate “manual override”. The shear screw will break at the application of 100 inch-pounds of torque, at which point the servo arm will travel freely. If the brass shear screw is broken during AP installation or usage, do not replace it with a standard screw - contact Dynon for a replacement shear screw. There will be a variety of methods used to install the other end of this control linkage to the existing mechanicals of the aircraft. Some systems will use a hole drilled into the bell crank as the point where the servo push rod/rod end combination interfaces with the controls. Others will use an attachment to existing linkage. Others may attach directly to the control stick itself. It is up to the installer to decide which method is best in terms of safety and AP functionality. Installers should always keep in mind the range of motion of the servo. Total servo arm travel needs to be limited to prevent an OVER CENTER condition (see caution note above), while still preserving the control surfaces’ full range of motion. Carefully consider the prevention of an over center condition when selecting the mounting location and linkage attachment point for any servo installation. The built-in control stops of the aircraft will limit the servo arm travel when installed correctly. Again, Dynon strongly recommends that the included Range of Motion Limiting Bracket be installed in order to absolutely prevent the possibility of an over center condition. The Range of Motion Limiting Bracket should not be used as a normal stop; the aircraft’s built-in stops should always be the primary range limit. 6-10 EFIS-D100 Installation Guide
Autopilot Installation and Configuration AP74 Mechanical Installation This section provides you with dimensions, panel location, and mounting information for the AP74 Dedicated Autopilot Interface. AP74 DIMENSIONS AND PANEL LOCATION The diagram below shows the AP74’s outer dimensions. Note that the instrument extends about 3.7” behind the panel, and that a harness can require up to three more inches. Use the dimensions (in inches) found on the diagram to plan for the space required by the instrument. The front bezels of the vertically oriented AP74 (100756-000) and are the same height as Dynon’s D100- series products and can be mounted close to – or abutted against – one if desired. Plan a panel location that allows for convenient operation of the knobs and buttons. If you plan on using the auto-dim feature, ensure that the instrument is in a location where the light sensor (small circle of rubber on the front of the instrument) can measure the true ambient light conditions in the cabin.
