EQUIPMENT LOCATION
The MD302 Standby Attitude Module is designed primarily to be installed in the instrument panel of the
aircraft. However, within the limitations of the environmental qualifications, other locations may be
acceptable when considered within the context of the specific application and with the appropriate
installation certification.
The MD302 has an extra wide viewing angle and AnyWay™ selectable orientation that allows for flexible
installation locations and options. The unit can be mounted vertically (knob left or knob right) or horizontally.
Once installed, the display orientation can be selected to match the installation. See Figure 2.1. However, be
sure to consider appropriate field-of-view in regards to pilot and/or co-pilot visibility and accessibility when
selecting a location to install the MD302. Note: when installing in vertical orientation, choose the knob
position based on whether or not the pilot’s hand will obscure the display during operation.
Additionally, consider what equipment is behind the panel which may impede the installation of the
MD302. Clearance for the unit as well as its electrical and pneumatic connections and routing must be
allowed. Be aware of routing cables near other electronics or with other wire bundles that may be
susceptible to high energy flow. Avoid sharp bends in cabling or hoses and routing near aircraft control
cables. Also avoid proximity and contact with aircraft structures, avionics equipment, heat sources or
other obstructions that could chafe or damage wires or hoses during flight and cause undesirable effects.
No external cooling is required.
