Undercarriage Panel

This blog covers the fuel pump panel.

Overview
The styling selected for the aircraft meant that the controls are installed in groups, this means that the undercarriage panel the control, power, hydraulic pressure gauge and indicator lights are fitted into one panel.

Installation.
A facia panel was designed to accommodate the schematic and all material used was 2024-T3 aluminium alodined after fabrication. 

The panel has a single AMP four [4] pin terminal featuring gold plated contacts and a robust lock. This fits into an aluminium bracket that is fixed to the facia using automotive trim tape to the facia and has proved remarkably robust. The 1 1/4'' UMA instruments are fitted with 9 pin RS232 plugs allowing disconnection.

The use of plus is critical to allow removal of the panel with all instruments and is one of the design criteria. 

The panel is fitted with hydraulic pressure, control and power to the pump with all lights featuring a press to test facility.

The panel is fitted with a series of plugs to allow removal. A four [4] pin AMP plug allow power and earth to be brought into the panel. The two [4] pin RS 232 plug is a special item rated at 30 plus amps and has gold plated contacts with the UMA instrument featuring a nine [9] pin RS 232 plug. All these plugs allow the removal of the panel as a single unit for servicing.
